  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

  With reference to FIG. 1, a vehicle equipped with a vehicle control apparatus according to an embodiment of the present invention will be described. This vehicle is an FF (Front engine Front drive) vehicle. The vehicle on which the vehicle control device according to the present embodiment is mounted may be a vehicle other than FF.

  The vehicle includes an engine 100, an automatic transmission 2000, a differential gear 5000, a drive shaft 6000, a front wheel 7000, and an ECU 8000. Automatic transmission 2000 includes a torque converter (not shown), a planetary gear unit 3000, a hydraulic circuit 4000, a shift operation device 8014, and a paddle shift device 1512.

  Automatic transmission 2000 increases or decreases the rotational speed of the crankshaft of engine 100 to a desired rotational speed by forming a desired gear stage. In the present embodiment, automatic transmission 2000 is a manual shift that upshifts or downshifts a gear according to a driver's operation instruction, in addition to an automatic shift mode that automatically changes the gear according to the state of the vehicle. Has a mode. The output gear of automatic transmission 2000 is in mesh with differential gear 5000.

  The automatic transmission 2000 may be a stepped automatic transmission or a continuously variable automatic transmission, and a plurality of separated gear ratios may be provided in the same manner as the stepped automatic transmission. May be set in advance, and the gear stage may be upshifted or downshifted in accordance with a shift instruction from the driver.

  A drive shaft 6000 is connected to the differential gear 5000 by spline fitting or the like. Power is transmitted to the left and right front wheels 7000 via the drive shaft 6000.

  Shift operation device 8014 includes a shift lever 8004, a position switch 8005, an upshift switch (1) 8010, and a downshift switch (1) 8012.

  The paddle shift device 1512 includes a paddle-shaped upshift switch (1) 1508 and a paddle-shaped downshift switch (2) 1510 as paddle shift switches.

  The ECU 8000 includes a vehicle speed sensor 8002, a position switch 8005, an accelerator position sensor 8007 provided on an accelerator pedal 8006, a stop lamp switch 8009 provided on a brake pedal 8008, and an upshift switch (1 ) 8010 and downshift switch (1) 8012 and upshift switch (2) 1508 and downshift switch (2) 1510 of paddle shift device 1512 are connected via a harness or the like.

  A vehicle speed sensor 8002 detects the vehicle speed of the vehicle from the rotational speed of the drive shaft 6000. The vehicle speed sensor 8002 transmits a signal representing the detection result to the ECU 8000.

  A position switch 8005 detects the position of the shift lever 8004. Position switch 8005 transmits a position signal indicating the position of shift lever 8004 to ECU 8000. ECU 8000 controls automatic transmission 2000 according to the received position of shift lever 8004. For example, when shift lever 8004 moves to the D (drive) position, position switch 8005 transmits a position signal indicating that shift lever 8004 is in the D position to ECU 8000. When the ECU 8000 receives a position signal indicating the D position, the automatic transmission mode is set, and the automatic transmission 2000 is controlled so that the gear stage is automatically changed according to the traveling state of the vehicle.

  Upshift switch (1) 8010 transmits an upshift signal to ECU 8000 when the driver moves shift lever 8004 to a position indicating an upshift instruction for the gear stage. The downshift switch (1) 8012 transmits a downshift signal to the ECU 8000 by the driver moving the shift lever 8004 to a position indicating a downshift instruction for the gear stage.

  Similarly, upshift switch (2) 1508 transmits an upshift signal to ECU 8000 when the driver operates the paddle portion of upshift switch (2) 1508. The downshift switch (2) 1510 transmits a downshift signal to the ECU 8000 when the driver operates the paddle portion of the downshift switch (2) 1510.

  In ECU 8000, the terminal for inputting the upshift signal from upshift switch (1) 8010 and the terminal for inputting the upshift signal from upshift switch (2) 1508 are the same terminal. Similarly, in ECU 8000, a terminal for inputting a downshift signal from downshift switch (1) 8012 and a terminal for inputting a downshift signal from downshift switch (2) 1510 are the same terminal.

  Shift operation device 8014 is a sequential shiftmatic mechanism, and further includes a shift gate 1500 having a sequential shift pattern as shown in FIG.

  Shift gate 1500 regulates the movement path of shift lever 8004. Shift gate 1500 has a predetermined shape, and includes a P (parking) position, an R (reverse) position, an N (neutral) position, a D position, an M (manual shift) position, and an upshift position. (Hereinafter referred to as (+) position) and a downshift position (hereinafter referred to as (−) position) are set.

  The shift gate 1500 has a shape that allows the shift lever 8004 to move to the (+) position or the (−) position when the shift lever 8004 moves to the M position set beside the D position. When shift lever 8004 moves to the M position, a position signal indicating that shift lever 8004 is at the M position is transmitted to ECU 8000.

  In the present embodiment, the shift gate 1500 may have a shape that cannot be moved to the (+) position or the (−) position unless the shift lever 8004 is moved to the M position, and particularly the sequential shift shown in FIG. It is not limited to patterns.

  When shift lever 8004 moves to the (+) position, upshift switch (1) 8010 transmits an upshift signal to ECU 8000. When shift lever 8004 moves to the (−) position, downshift switch (1) transmits a downshift signal to ECU 8000.

  Note that when the driver moves the shift lever 8004 to the M position, the M position is set as the reference position 1502, and thus the operation force after the driver moves the shift lever 8004 to the (+) position or the (−) position. When is released, mechanical force by a spring or the like acts on the shift lever 8004 to return to the reference position 1502.

  As shown in FIG. 3, the paddle shift device 1512 is provided on the rear side (front side of the vehicle) of the steering wheel 1520. The paddle shift device 1512 may be provided at a place where the driver can operate the steering wheel 1520 (that is, when the driver is holding the steering wheel with both hands). The position shown in FIG.

  In the present embodiment, it is assumed that the driver faces the steering wheel 1520, the upshift switch (2) 1508 is provided on the right side, and the downshift switch (2) 1510 is provided on the left side. The positions where the switch (2) 1508 and the downshift switch (2) are provided are not particularly limited to the positions shown in FIG.

  When the driver operates the upshift switch (2) 1508 with a finger while holding the steering wheel 1520 with both hands, the upshift switch (2) 1508 transmits an upshift signal to the ECU 8000. Specifically, when the driver pulls the paddle portion of upshift switch (2) 1508 toward the front, upshift switch (2) 1508 transmits an upshift signal to ECU 8000. When the driver releases the operating force applied to the paddle portion of the upshift switch (2) 1508, the paddle portion returns to the reference position.

  Similarly, when the driver operates downshift switch (2) 1510 with a finger, downshift switch (2) 1510 transmits a downshift signal to ECU 8000. Specifically, when the driver pulls the paddle portion of the downshift switch (2) 1510 toward the front, the downshift switch (2) 1510 transmits a downshift signal to the ECU 8000. Note that when the driver releases the operating force to the paddle portion of the downshift switch (2) 1510, a mechanical force by a spring or the like acts to return the paddle portion to the reference position.

  Instead of the paddle shift device 1512, a shift operation device including an upshift switch and a downshift switch provided on the steering wheel 1520 may be used.

  In the vehicle having the above-described configuration, a vehicle on which only the shift operation device 8014 is mounted and a paddle shift device 1512 in addition to the shift operation device 8014 are mounted as devices for performing an operation to increase or decrease the gear position of the automatic transmission. The required vehicle specifications (for example, speed change characteristics) differ from those of the vehicle. However, if a control unit corresponding to each vehicle specification is set, the cost may increase.

  Therefore, in the present embodiment, when ECU 8000 detects that a gear stage upshift or downshift instruction has been received when shift lever 8004 has not been moved to the M position, paddle shift device 1512 It is characterized in that the automatic transmission 2000 is controlled based on the recognition result and the state of the shift operation device 8014 or the paddle shift device 1512 by recognizing that it is mounted on the vehicle.

  Specifically, the ECU 8000 causes the paddle shift device 1512 to move to the vehicle when the position of the shift lever 8004 based on the detection signal from the position switch 8005 is not the M position and receives an upshift signal or a downshift signal. Recognize that it is installed.

  Further, when the ECU 8000 recognizes that the paddle shift device 1512 is mounted on the vehicle, the ECU 8000 sets a shift characteristic of the automatic transmission 2000 that is different from that when the paddle shift device 1512 is not mounted on the vehicle. Automatic transmission 2000 is controlled based on the states of shift operation device 8014 and paddle shift device 1512 and the set shift characteristics.

  FIG. 4 shows a functional block diagram of ECU 8000 which is a vehicle control apparatus according to the present embodiment.

  As shown in FIG. 4, ECU 8000 includes an attachment recognition unit 100, a recognition information storage unit 200, and a manual shift control unit 300.

  The wearing recognition unit 100 receives a position signal, an upshift signal, and a downshift signal from the shift operation device 8014. The attachment recognition unit 100 receives the upshift signal and the downshift signal from the paddle shift device 1512.

  When the shift position is a shift position other than the M position based on the position signal, and the reception recognition unit 100 receives an upshift signal or a downshift signal, the mounting recognition unit 100 is mounted on the vehicle. Recognize that. The attachment recognition unit 100 transmits the recognition result (that is, whether or not the paddle shift device 1512 is attached) to the recognition information storage unit 200.

  The recognition information storage unit 200 stores the recognition result. In addition to the recognition result, the recognition information storage unit 200 may store shift characteristics corresponding to whether or not the paddle shift device 1512 is attached.

  The manual shift control unit 300 reads out stored information about whether or not the paddle shift device 1512 is mounted from the recognition information storage unit 200, and corresponds to whether or not the paddle shift device 1512 is mounted among a plurality of separately stored shift characteristics. Select the shift characteristics. Alternatively, the manual shift control unit 300 may read shift characteristics according to whether or not the paddle shift device 1512 is attached from the recognition information storage unit 200.

  Manual shift control unit 300 controls automatic transmission 2000 based on the selected shift characteristic and an upshift signal or a downshift signal received from at least one of shift operation device 8014 and paddle shift device 1512. .

  For example, when manual shift control unit 300 receives an upshift signal, manual shift control unit 300 transmits a control signal to automatic transmission 2000 so that the current gear stage is upshifted by one stage. Alternatively, when manual downshift control unit 300 receives the downshift signal, it transmits a control signal to automatic transmission 2000 so that the current gear stage is downshifted by one stage.

  When the paddle shift device 1512 is mounted on the vehicle, the manual shift control unit 300 fixes the gear stage changed by the shift operation, and when the paddle shift device 1512 is not mounted on the vehicle, The automatic transmission 2000 may be controlled so that the gear stage changed according to (1) is set to the maximum gear stage to be a gear stage according to the state of the vehicle.

  The manual shift control unit 300 also includes a shift that fixes the gear stage changed by the shift operation and a shift that uses the gear stage changed by the shift operation as the maximum gear stage depending on whether the paddle shift device 1512 is attached. The selection is not particularly limited.

  For example, the manual shift control unit 300 shifts according to the state of the vehicle with the gear stage changed by the shifting operation as the maximum gear stage regardless of whether the paddle shift apparatus 1512 is mounted or not. The timing of shifting (that is, the shift diagram) may be changed depending on the presence or absence.

  When the paddle shift device 1512 is mounted, the manual shift control unit 300 controls the automatic transmission 2000 using a shift diagram corresponding to sports driving with improved acceleration performance, and the paddle shift device 1512 When not mounted, the automatic transmission 2000 may be controlled using a shift diagram in which fuel consumption performance or quietness performance is improved as compared with a shift diagram corresponding to sports driving.

  In the present embodiment, each of the attachment recognition unit 100, the recognition information storage unit 200, and the manual shift control unit 300 is a program in which a CPU (Central Processing Unit) provided in the ECU 8000 is stored in the memory. Although described as functioning as software realized by execution, it may be realized by hardware. Such a program is recorded on a storage medium and mounted on the vehicle.

  With reference to FIG. 5, a control structure of a program executed by ECU 8000 which is the vehicle control apparatus according to the present embodiment will be described.

  In step (hereinafter, step is referred to as S) 100, ECU 8000 determines whether or not the shift position is the M position. If the shift position is the M position (YES in S100), the process returns to S100 and waits until it is determined that the shift position is not the M position. If the shift position is not the M position (NO in S100), the process proceeds to S102.

  In S102, ECU 8000 determines whether there is an input of any one of the upshift signal and the downshift signal. If any one of the upshift signal and the downshift signal is input (YES in S102), the process proceeds to S104. If not (NO in S102), the process proceeds to S106.

  In S104, ECU 8000 recognizes that paddle shift device 1512 is mounted on the vehicle. In S106, ECU 8000 recognizes that paddle shift device 1512 is not attached to the vehicle.

  In S108, ECU 8000 performs shift control of automatic transmission 2000 based on the recognition result and the upshift signal or downshift signal.

  The operation of ECU 8000 serving as the vehicle control apparatus according to the present embodiment based on the above-described structure and flowchart will be described.

  For example, as shown in FIG. 1, it is assumed that the paddle shift device 1512 is mounted on a vehicle. When the shift position is not the M position (NO in S100), the driver operates the upshift switch (2) 1508 or the downshift switch (2) 1510, whereby the upshift switch (2) 1508 or the downshift switch (2) An upshift signal or a downshift signal is transmitted from 1510 to ECU 8000 (YES in S102), so that it is recognized that paddle shift device 1512 is mounted on the vehicle (S104).

  Then, the shift control of the automatic transmission 2000 is performed based on the recognition result and the upshift signal or the downshift signal. For example, as shown in FIG. 6, when it is recognized that the paddle shift device 1512 is attached to the vehicle (that is, when it is recognized that the specification is the specification of the vehicle A), A is set. The speed change characteristic corresponding to type A is a sport type speed change characteristic. Therefore, ECU 8000 controls automatic transmission 2000 based on the state of the vehicle, the upshift signal or downshift signal, and the sport-type shift characteristics.

  Alternatively, as shown in FIG. 7, it is assumed that the paddle shift device 1512 is not attached to the vehicle. When the shift position is not the M position (NO in S100), no upshift signal or downshift signal is received (NO in S102). Therefore, it is recognized that the paddle shift device 1512 is not mounted on the vehicle (S104).

  Then, the shift control of the automatic transmission 2000 is performed based on the recognition result and the upshift signal or the downshift signal. For example, as shown in FIG. 6, when it is recognized that the paddle shift device 1512 is not mounted on the vehicle (that is, when it is recognized that the vehicle B is a specification), the manual transmission mode is the type. B is set. The speed change characteristic corresponding to type B is a luxury type speed change characteristic. Therefore, ECU 8000 controls automatic transmission 2000 based on the state of the vehicle, the upshift signal or the downshift signal, and the luxury type shift characteristics.

  Note that a common ECU is used as the ECU 8000 regardless of whether or not the paddle shift device 1512 is mounted on the vehicle.

  As described above, according to the control device for a vehicle according to the present embodiment, when it is detected that an instruction for upshifting or downshifting the gear stage is received when the shift lever is not moved to the M position, The gear stage upshift or downshift operation is not performed by the operation of the shift lever, that is, the gear stage upshift or downshift operation is performed by the operation of the paddle shift device. Can be specified. Thereby, it is possible to specify with high accuracy whether or not the paddle shift device is mounted on the vehicle. Therefore, the automatic transmission can be controlled in accordance with whether or not the paddle shift device is mounted based on the recognition result and the state of the shift operation device or the paddle shift device. That is, it is not necessary to prepare a separate control device depending on whether or not the paddle shift device is mounted on the vehicle. Thereby, an increase in cost can be suppressed. Therefore, it is possible to provide a vehicle control device and a control method for specifying a device connected as an operation device for an automatic transmission and performing shift control corresponding to the specified device.

  In addition, since the signal from the paddle shift device and the signal from the shift operation device are input from a common input terminal, the communication line of the paddle shift device and the communication line of the shift operation device are arranged in parallel inside and outside the ECU. Therefore, an increase in cost can be suppressed.

  Further, when it is recognized that the paddle shift device is mounted on the vehicle, the paddle shift device is mounted by setting a shift characteristic of the automatic transmission different from that when the paddle shift device is not mounted on the vehicle. The automatic transmission can be controlled in accordance with the presence or absence.

  In addition, since the ECU can be used both when the shift operation device and the paddle shift device are included and when only the shift operation device is included, the parts can be shared and the cost increase can be suppressed. it can.

  Further, according to such a vehicle control device, for example, when the shift position is not the M position with respect to the vehicle before shipment, the upshift switch (2) or the downshift switch (2) is operated, By storing the presence or absence of the paddle shift device in a nonvolatile memory, the automatic transmission is controlled based on the shift characteristics corresponding to the presence or absence of the paddle shift device in the vehicle after shipment. .

  Further, in the present embodiment, when the shift position is not the M position, if there is no upshift signal or downshift signal from the upshift switch (2) or the downshift switch (2), the paddle shift device is attached to the vehicle. The automatic transmission is controlled based on the shift characteristics when the paddle shift device is not mounted on the vehicle. However, the present invention is not particularly limited to such a control mode. .

  For example, the speed change characteristic when the paddle shift device is not attached to the vehicle is set as an initial value, and when the shift position is not the M position, unless the upshift signal or the downshift signal is received, the shift value is based on the initial value. When the automatic transmission is controlled and the upshift signal or downshift signal is received when the shift position is not the M position, the automatic transmission 2000 is controlled based on the shift characteristics when the paddle shift device is mounted on the vehicle. You may make it do.
