Description

  The present invention relates to an in-vehicle information transmission device for transmitting information to a passenger in a vehicle.

  Conventionally, various information is given from a vehicle to a passenger inside the vehicle. For example, a corresponding operation sound is emitted to the driver when the winker operates or reverses, and these operations can be confirmed as an aid to the driving operation. When the door is in an open state, a warning is given with a lamp or the like. Furthermore, when a sensor detects an obstacle around the vehicle, there is an alarm that alerts the user. In addition, in recent years, there are also those that issue a warning when the running lane is protruding while detecting the running state of the vehicle, or when the danger of a collision with an obstacle or other vehicle on the course is detected, Advanced information is being transmitted to passengers.

  Various means for transmitting such information have been proposed, and among them, there is an apparatus for transmitting information to the driver via a steering wheel, as described in Patent Document 1 below. This is configured to give a mechanical stimulus to the palm of the driver by deforming the grip portion of the steering wheel (steering) based on vehicle state information, ambient environment information, and the like. In this way, it is possible to maintain a good in-vehicle environment by transmitting information necessary for driving only to the driver and not giving unnecessary information to other passengers.

JP 2007-22340 A

  Although it can be said that it is preferable in order to maintain the vehicle interior environment, it is preferable to transmit information only to those who need information as in Patent Document 1 described above and not to transmit information to those who do not need information. It can be said that it is important to communicate to those who do. For this purpose, it is necessary to prevent information that should be given due to vibration and noise during traveling from being buried and making it impossible for the passenger to make a determination.

  Further, in the configuration in the above-described Patent Document 1, information transmission is performed by mechanical stimulation due to deformation of the gripping portion, so that the information transmission speed is reduced, and it is not suitable for providing urgent types of information. It can also be said that it is difficult to transmit various information using the same means.

Specifically, the information given to the passenger can be transmitted in a form that can be easily distinguished from the vibration of the vehicle.

Characterized in that it configured to determine the operation command signal to the.

  If comprised in this way, it will become possible to notify a passenger appropriately by giving required information as a small vibration, reducing the vibration transmitted from a vehicle. In addition, since the transmission of information is directly performed by vibration, it is possible for the passenger to reliably determine even if the interior of the vehicle is noisy. Furthermore, since vibration with high transmission speed is used as an information transmission means, it is possible to form various vibration patterns and to handle various information separately.

  In addition, in order to appropriately notify information to a plurality of passengers, the vibration detection means and the vibration means are configured as corresponding information transmission units, and the information transmission unit Are provided at each of a plurality of locations corresponding to the seating position of the passenger, and an operation command signal is determined for each seating position based on a superimposed signal obtained by superimposing a vibration canceling signal and an information signal at each seating position. Thus, it is preferable to configure so as to output to the vibration means.

  In addition, in order to give only necessary information to each passenger and prevent unpleasant feelings from being caused by the transmission of unnecessary information, the information signal given through the information signal generator varies depending on the seating position. It is preferable to configure so that the

  In addition, depending on the situation, a non-operation mode in which no vibration force is generated by the vibration means, a vibration suppression mode that only cancels vehicle vibration, and an information notification mode that transmits information by vibration can be used separately. In order to make it possible, a signal setting unit that outputs an on / off signal to the cancellation signal generation unit and the information signal generation unit is provided, and the cancellation signal generation unit and the information signal generation unit are input. It is preferable that the signal generation operation is switched between the execution state and the stop state in accordance with the ON / OFF signal.

  In addition, in order to be able to selectively use the non-operation mode in which vibration is not generated by the vibration means for each seating position, the vibration suppression mode, and the information notification mode, the control unit is provided for each information transmission unit. The canceling signal generating unit, the information signal generating unit, and the superimposing unit are provided, and the signal setting unit outputs individual on / off signals to each canceling signal generating unit and each information signal generating unit. Thus, it is preferable that the signal generation operation in each signal generation unit is individually switched between the execution state and the stop state.

  Furthermore, in order to enable more appropriate information transmission to the passenger, the installation location of the vibration means and vibration detection means is at least one of a handle, a seat, and a seat belt retractor. It is preferable to have a configuration.

  According to the present invention described above, it is possible to provide an in-vehicle information transmission device that allows a passenger to easily discriminate given information from vibrations and noises of a vehicle and can transmit a variety of information. Is possible.

  Embodiments of the present invention will be described below with reference to the drawings.

  The vehicle-mounted information transmission device of this embodiment has a configuration as shown in the block diagram of FIG. 1, and is largely an electromagnetic actuator (hereinafter simply referred to as “actuator” as a vibration means for transmitting information to a passenger. ) Five information transmission units (hereinafter simply referred to as “units”) U1 to U5 configured by associating A1 to A5 and acceleration sensors S1 to S5 as vibration detection means one by one. The control unit 2 is connected to these.

  The actuators A1 to A5 are devices that are controlled by voltage and cause the mover to reciprocate with respect to the main body according to the voltage pattern. For example, a linear actuator described in JP-A-2004-343964 is used as a drive source. it can. Furthermore, it is widely known that a stronger reaction force can be generated by attaching a weight to the tip of the mover to increase the excitation force, and each of the actuators A1 to A5 is similarly configured in this embodiment. doing. By using such actuators A1 to A5, a large excitation force can be generated, and the frequency and waveform of the excitation force can be controlled by voltage.

  A unit U1 composed of the actuator A1 and the acceleration sensor S1 is provided in the driver's seat as shown in FIGS. 2 and 3 to transmit information to the driver. More specifically, the actuator A1 is incorporated in the handle 74 as an information transmission place, and the acceleration sensor S1 is provided in a dashboard 73 that supports the handle 74.

  A unit U2 composed of the actuator A2 and the acceleration sensor S2 is incorporated in the passenger seat 82, and units U3 to U5 composed of the actuators A3 to A5 and the acceleration sensors S3 to S5 are arranged at the rear. It is provided inside the seats 83 to 85 at each seating position. The control unit 2 is housed in a dashboard 73 and is partially omitted in the drawing, but is electrically connected to the in-vehicle computer 72 for controlling the engine 71 and the above units U1 to U5. It is connected to the.

  As described above, it is important that the actuators A1 to A5 and the corresponding acceleration sensors S1 to S5 are installed close to each other, and at least be associated with each other in terms of vibration transmission. That is, the term “unit” as used herein includes not only the case where they are integrated, but also the case where they are attached to two points that have a one-to-one correspondence relationship and whose transfer function is known. As described later, this is based on the installation location of the acceleration sensors S1 to S5 as a reference point, and based on the vibration detection signal obtained there, grasps the vibration at the installation location of the actuators A1 to A5 as response points. Thus, the actuators A1 to A5 are controlled to suppress vibration at the response point, and another vibration is generated as an information signal.

  Hereinafter, returning to FIG. 1, a detailed configuration will be described.

  The control unit 2 includes cancellation signal generation units 21a to 21e and information signal generation units 22a to 22e that generate cancellation signals and information signals corresponding to the units U1 to U5, respectively. In addition, superimposing units 23a to 23e that generate and output a superimposed signal in which the cancellation signal generated by these and the information signal are superimposed are provided, and operation signals are amplified after the amplified signals are amplified by amplifiers 24a to 24e. It is configured to be given to each actuator A1 to A5 as a signal.

  Each of the canceling signal generation units 21a to 21e receives vibration detection signals obtained through the respective acceleration sensors S1 to S5, and generates canceling signals for canceling vibrations at the installation positions of the actuators A1 to A5 based on the signals. Generate. Further, the canceling signal generators 21a to 21e are supplied with a rotational speed signal of the engine 71 from the in-vehicle computer 72. By using this signal as a reference, the canceling signal can be generated with high accuracy. It is like that.

  On the other hand, the information signal generators 22a to 22e are given various kinds of information to be notified to the passengers through an information input unit (not shown), and generate information signals in a form corresponding to these information.

  As described above, the cancellation signal generated by the cancellation signal generation units 21a to 21e and the cancellation signal generated by the information signal generation units 22a to 22e are input to the superimposition units 23a to 23e, where a superimposed signal is generated by superimposing both signals. After being amplified by the amplifiers 24a to 24e, they are given to the actuators A1 to A5 as operation command signals.

  As will be described later, when the generation of the information signal is in a stopped state and the signal given to the actuators A1 to A5 is an operation command signal based only on the cancellation signal, it functions as a simple vibration suppression. . Thus, when attention is paid only to the vibration control technology, it can be said that this control means is substantially the same as that described in JP-A-2009-275814. Therefore, the detailed vibration suppression principle and detailed configuration are omitted.

  Further, the canceling signal generating units 21a to 21e and the information signal generating units 22a to 22e are connected to switching units 31a to 31e and 32a to 32e, respectively, and an on signal or an off signal is input thereto. ing. The canceling signal generation units 21a to 21e and the information signal generation units 22a to 22e are in a signal generation operation state when an on signal is input, and are stopped in a signal generation operation state when an off signal is input. I have to.

  Further, the switching units 31 a to 31 e and 32 a to 32 e constitute one on / off signal output unit 3, and this on / off signal output unit 3 corresponds to each switching unit 31 a to 31 e, 32 a according to the input from the signal setting unit 4. The outputs of .about.32e can be individually changed between the on signal and the off signal. That is, the execution and stop of the signal generation operation in an arbitrary signal generation unit can be appropriately switched by the input from the signal setting unit 4.

  Further, the switching as described above executes only the cancellation signal generation units 21a to 21e in the non-operation mode in which both the cancellation signal generation units 21a to 21e and the information signal generation units 22a to 22e are stopped for each seating position. It is possible to switch between the three modes of the information notification mode in which both the vibration suppression mode in the state and the cancellation signal generation units 21a to 21e and the information signal generation units 22a to 22e are in the execution state.

  With the above configuration, the operation can be performed specifically as follows. Hereinafter, description will be made with reference to FIG.

  For example, when information is transmitted by the unit U1 attached to the driver's seat, first, a dash that is close to the handle 74 that is an information transmission place (response point), supports the rotating shaft, and is related in terms of vibration transmission. A vibration detection signal is output by an acceleration sensor 74 provided in the board 73 (reference point).

  And in the cancellation signal production | generation part 21a, the cancellation signal for canceling the vibration in the installation place of actuator A1 is produced | generated. When the installation location of the acceleration sensor S1 and the actuator A1 are close to each other, it can be regarded that the acceleration sensor S1 and the actuator A1 are installed, so that the cancellation signal is obtained by inverting the phase of the detection signal from the acceleration sensor S1. It can be. However, if it cannot be considered that the positions of the actuator A1 and the acceleration sensor S1 coincide with each other, the transfer function between the mounting positions of the actuator A1 and the acceleration sensor S1 is checked in advance, and the vibration at the reference point is used by using the transfer function. It is necessary to obtain the vibration waveform generated at the response point from the detection signal and to use the waveform having the opposite phase to that of the vibration waveform as the cancellation signal.

  In addition, since the vibration in the vehicle includes a lot of vibration from the engine 71, the waveform of the engine speed component obtained from the in-vehicle computer 72 is generated in advance as a reference waveform as described above, and based on this, An offset signal is generated. In this way, it is possible to appropriately generate a canceling signal without causing a control delay in response to an increase or decrease in engine speed.

  On the other hand, in the information signal generation part 22a, the information signal of the form according to the kind of the information is produced | generated by inputting the information which should be given to a driver | operator. In the drawing, a state where a rectangular wave signal is generated is shown as an example. This information signal can be formed in an arbitrary form such as a triangular wave as well as a rectangular wave, and can be created in various forms by combining a frequency, an amplitude, or an intermittent pattern. Such a pattern is formed by a combination of fine changes. However, since vibration with a high transmission speed is used as the transmission means, it becomes possible for the passenger to easily distinguish the pattern.

  The cancellation signal generated by the cancellation signal generation unit 21a and the information signal generated by the information signal generation unit 22a are input to the superposition unit 23a, where a superposition signal obtained by adding both signals is generated.

  The superimposed signal is amplified through the amplifier 24a and output as an operation command signal to the actuator A1, thereby generating an excitation force having the same waveform. By doing so, the original vibration of the vehicle that originally occurred at the place where the actuator A1 is installed is canceled and suppressed by the vibration corresponding to the cancellation signal included in the superimposed signal. Then, a signal corresponding to the information signal included in the superimposed signal remains, and is transmitted to the driver through the handle 74 as a predetermined pattern of vibration corresponding to the information.

  In this way, it is possible to newly generate vibration as an information signal after suppressing the inherent vibration of the vehicle at the installation location of the actuator A1 by the canceling signal. Therefore, the vibration as the information signal is easily distinguished from the vibration inherent in the vehicle by the passenger. In addition, since the vibration as the information signal can be reduced, it can be transmitted only to the driver who should give information and not to other passengers. , Those who do not need the information will not be discomforted by being given extra information. Furthermore, since the information transmission means is vibration, even if the interior of the vehicle is noisy, it is possible to reliably transmit to the driver. Even if a signal is formed with a vibration pattern that varies finely depending on the type of information signal, the original vibration caused by the vehicle is reduced, so that the discrimination is easy. Therefore, information can be transmitted in various patterns.

  Up to this point, the description has been made mainly on information transmission to the driver. However, for the passengers other than the driver, the actuators A2 to A5 and the sensors S2 to S5 are located inside the seats 82 to 85 according to the seating position. Units U2 to U5 are incorporated, and the control unit 2 controls these units, thereby suppressing vibrations inherent to the vehicle and transmitting information. Similar to the steering wheel 74 for the driver, by transmitting information through the seats 82 to 85, it is possible to appropriately transmit information to passengers other than the driver in distinction from vibrations and noises inherent to the vehicle. .

  Sensors S2 to S5 are provided corresponding to the actuators A2 to A5, respectively, and by allowing the positions of the sensors S2 to S5 to be associated with each other in terms of vibration transmission, it is possible to appropriately suppress the original vibration of the vehicle. .

  As information to be given to passengers other than the driver, firstly, a danger notification signal when a danger of collision with an obstacle is detected can be considered. By giving such information, passengers other than the driver can be prepared for danger, and the impact caused by the collision can be reduced. Further, as information different for each seating position, it is conceivable to provide an adjacent door opening notification signal to the door-side seats 82, 83, 85. By doing so, it is possible to give information for prompting confirmation of closing of the door only to the person who operates the door. Further, it is possible to provide information for prompting the user to attach the seat belt only to the seating position by limiting the seat belt to a person who is not wearing the seat belt. As described above, it is possible to divide each seating position and transmit information only to persons who are related to information.

  Furthermore, for those who do not need to transmit such information, the information signal generators 22a to 22e generate information signals for each sitting position through the on / off signal output unit 3 from the signal setting unit 4 shown in FIG. Can be switched to the vibration suppression mode. By doing so, it is possible to use only the vibration suppression function and not to use the information transmission function. For example, such a mode can be suitably used when carrying an infant.

  Moreover, the non-operation mode which stopped each signal generation can be used suitably with respect to the person who likes the original vibration of a vehicle. Moreover, this non-operation mode can be used suitably also when there is no passenger in a seating position, and can also suppress unnecessary energy consumption.

  The mode switching through the signal setting unit 4 can be performed individually according to the seating position, and the information notification mode for transmitting information after performing vibration suppression, and the above-described non-operation mode and vibration suppression mode. Can be made to meet various passenger preferences.

  Without considering the distinction between the driver and the passenger, the information given to the passenger is generally considered as shown in the table shown in FIG. 5. By applying the present invention, the current notification method is changed to the vibration pattern. It can be replaced with the main information transmission method. In addition, as described in the table, there is a risk that information may be insufficient when information is transmitted using only vibration patterns. For example, when transmitting information from car navigation systems, combining vibration patterns and display displays This makes it possible to reduce the time for the driver to watch the display and to transmit information while improving safety.

  As described above, the vehicle-mounted information transmission device of the present embodiment is installed in a part of the vehicle 7 and generates actuators according to the input operation command signal, and the actuators A1 to A5. Acceleration sensors S1 to S5 for detecting vibrations in a part of the vehicle 7 associated with the installation location of the vehicle, and controlling the vibrations generated by the actuators A1 to A5 by outputting the operation command signals to the actuators A1 to A5. A canceling signal for generating a canceling signal for canceling the vibration at the installation location of the actuators A1 to A5 based on the vibration detection signals from the acceleration sensors S1 to S5. Generators 21a to 21e and information signal generators 22a to 22e that generate information signals according to information transmitted to the passengers And superimposing units 23a to 23e that generate superposed signals by superimposing the canceling signals from the canceling signal generating units 21a to 21e and the information signals from the information signal generating units 22a to 22e, and the superimposing units 23a to 23e. The operation command signal is determined based on the superimposed signal.

  Since it is configured in this manner, it is possible to appropriately notify necessary information with a small vibration that is not transmitted to other unrelated persons while reducing vibration transmitted from the vehicle 7 to the passenger. It becomes possible. Further, since the information is given by vibration, it is easy for the passenger to detect, and the information can be reliably transmitted even when the interior of the vehicle is noisy. Furthermore, since a means having a large transmission speed called vibration is used, it is easy to discriminate even if the vibration pattern is varied depending on the type of information, and this makes it possible to provide various information.

  The acceleration sensors S1 to S5 and the actuators A1 to A5 are configured as corresponding information transmission units U1 to U5, and the information transmission units U1 to U5 are provided at a plurality of positions corresponding to the seating positions of the passengers. Each is provided, and is configured to determine an operation command signal for each seating position and output it to the actuators A1 to A5 based on a superimposed signal obtained by superimposing a vibration canceling signal and an information signal at each seating position. Therefore, even when there are a plurality of passengers, information can be appropriately notified to each passenger.

  In addition, since the information signal to be given through the information signal generators 22a to 22e is made different depending on the seating position, only necessary information is given to each passenger, and unnecessary information is not given. , No more unpleasant feelings to the passengers.

  In addition, the canceling signal generators 21a to 21e and the information signal generators 22a to 22e are provided with a signal setting unit 4 that outputs an on / off signal, and the canceling signal generators 21a to 21e and the information signal generator Since 22a-22e is comprised so that signal generation operation may be switched between an execution state and a stop state according to the on-off signal input, according to a situation, there is no vibration generation | occurrence | production by actuator A1-A5. The operation mode, the vibration suppression mode, and the information notification mode can be properly used, and energy consumption can be suppressed when the non-operation mode or the vibration suppression mode is set.

  The control unit 2 includes the cancellation signal generation units 21a to 21e, the information signal generation units 22a to 22e, and the superposition units 23a to 31e corresponding to the information transmission units U1 to U5, The signal setting unit 4 outputs individual on / off signals to the canceling signal generation units 21a to 21e and the information signal generation units 22a to 22e, so that signal generation in the signal generation units 21a to 21a and 22a to 22e is performed. Since the operation is individually switched between the execution state and the stop state, a non-operation mode in which no vibration is generated by the actuators A1 to A5 for each seating position, a vibration suppression mode in which only vibration suppression is performed, Since the vibration control and the information notification mode for notifying information can be set, an appropriate operation mode can be selected according to the passenger.

  In addition, since the actuators A1 to A5 and the acceleration sensors S1 to S5 are installed at least one of the handle 74 and the seats 82 to 85, information can be effectively transmitted to the passenger.

  The specific configuration of each unit is not limited to the above-described embodiment.

  For example, a part of the above-described embodiment can be modified to configure the vehicle-mounted information transmission device 101 as shown in FIG. In addition, the same code | symbol is attached | subjected to the part which is common in FIGS. As shown in FIG. 6, the gist of the present invention is not limited to the case where the actuators A11 to A11 and the acceleration sensors S11 to C correspond to each other one to one. That is, each cancellation signal generation is performed so that vibrations generated at the installation locations of the actuators A11 to A1 are obtained by a common signal from the sensor group SA including the acceleration sensors S11 to S1, and cancellation signals corresponding to the vibrations are generated. You may comprise the parts 21a-21e. In short, it is only necessary to know the transfer function between each response point where the actuators A11 to 11 are installed and the reference point for detecting the vibration, and to accurately obtain the vibration at the response point. If possible, the reference point may be a single point or a plurality of points. Therefore, although there is a possibility that the vibration control accuracy may be lowered, the sensor group SA can be configured by only one acceleration sensor S11.

  Further, the acceleration sensor S11 as the vibration detecting means is not limited to the form shown in FIG. 6, and as long as it can output information on the vibration waveform including the magnitude and phase of the vibration at the reference point to the cancellation signal generation units 21a to 21e. It is also possible to use various alternative means. For example, in the case where the vibration control is performed only for the vibration of the engine 71 which is the largest vibration source in the vehicle, the magnitude of the vibration of the engine 71 can be substantially determined by the rotational speed. Only by extracting the rotational speed signal of the engine 71 through 72, the magnitude and vibration waveform of the engine 71 as a reference point are obtained, and based on this, the cancellation signal generators 21a to 21e generate cancellation signals. Is also possible. In such a case, the in-vehicle computer 72 itself functions as a means for replacing the sensor group SA.

  Furthermore, as shown in FIG. 6, depending on the positional relationship of the actuators A <b> 11 to 11, a one-to-one correspondence with the amplifiers 24 a to 24 e is not necessarily required. The actuator A11 may be driven, or signals output from the plurality of amplifiers 24a to 24e may be used while being switched as operation command signals for one actuator A11. That is, it is only necessary that the operation command signals are given by the amplifiers 24a to 24e to the actuator group AA including the actuators A11 to A11. The number of amplifiers 24a to 24e is not limited to five.

  In the above-described embodiment, the acceleration sensors S1 to S5 are used as the vibration detection means. However, the present invention is not limited to this configuration as long as the vibration can be detected, and a general vibration speed and vibration displacement can be detected. A simple sensor can be used.

  In the above-described embodiment, the electromagnetic linear actuators A1 to A5 are used as the vibration means. However, the vibration waveform is not limited to the above-described configuration, as long as the vibration waveform can be finely controlled. An electromagnet or vibrator having a configuration can also be used.

  In the present embodiment, the vehicle capacity is assumed to be five on a vehicle, and the vehicle-mounted information transmission device is attached to the vehicle. However, it can be appropriately changed according to the size of the vehicle. That is, when the number of passengers is increased or decreased from five, it is sufficient that the units 2 to U5 are increased or decreased and the control unit 2 is made to correspond thereto.

  In the above-described embodiment, the actuators A1 to A5 and the acceleration sensors S1 to S5 are installed at the handle 74 or the seats 82 to 85. Communication may be performed.

  It is also possible to provide a plurality of information transmission units for one seating position so that information is transmitted to a single passenger from a plurality of locations.

  Other configurations can be variously modified without departing from the spirit of the present invention.
