[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyless system capable of remotely unlocking and locking a door lock by operating a remote control in an automobile, and particularly, to easily open a locked door when the automobile collides. Keyless system that can be opened.

[0002]

2. Description of the Related Art A keyless system that can be remotely unlocked and locked by operating a remote controller can be used to unlock and lock a door by simply operating a portable transmitter without having to insert the key into the keyhole. Since it can open and close windows, it is being adopted in many vehicles. In this keyless system, the identification code is collated so as not to be unlocked by another person, and only when they coincide, the locking and unlocking operations are performed.

[0003]

While the vehicle is traveling, it is customary to lock the door automatically or manually for the safety of passengers. However, when an accident such as a collision occurs, the lock door needs to be unlocked in order for the passenger to escape to the outside of the vehicle. However, when the occupant cannot unlock the vehicle by himself / herself, he / she often has no duplicate key, and even if he / she tries to unlock the keyless system remote controller, he / she can open the door if he / she does not have the remote controller with the same identification code However, there was a problem of affecting rescue activities. In view of the conventional problems described above, the present invention aims to provide a keyless system capable of easily unlocking a door lock when an accident occurs even when the door lock is in a locked state. I am trying.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described with reference to examples. FIG. 1 shows the configuration of the embodiment. The remote controller 100 as a transmitter has a switch S1 for raising and lowering the power window of the vehicle and a switch S2 for locking and unlocking the door.
By operating 2, the operation command signal corresponding to the operation including the identification code of the remote controller 100 is transmitted from the antenna as a radio wave.

Receiving device 200 mounted on a vehicle
Has a control unit (C / U) 3, to which a motor 4 for locking and unlocking a door lock to be controlled and a motor 5 for raising and lowering a power window are connected, and an output terminal is further connected. The right flasher 6 and the left flasher 7 of the vehicle are connected via a timer 8.
The timer 8 blinks the flasher 6 and the flasher 7 for a fixed time.

The tuner 1 to which the antenna is connected is connected to an identification code determination section (ID determination section) 2 where the identification code included in the received signal of the tuner 1 is determined. When the identification code set in the identification code determination section 2 and the received identification code match, the received signal is output to the control unit 3 as it is. The control unit 3 decodes the operation command from the input received signal and executes it by rotating the electric motor 4 and the electric motor 5.

On the other hand, a collision determination section 10 is connected to the identification code determination section 2 and the control unit 3. Collision determination unit 1
A G sensor 9 for detecting a vehicle collision is connected to 0. The G sensor 9 detects the acceleration (deceleration) of the vehicle every moment, and the collision determination unit 10 outputs a collision signal when the deceleration exceeds a predetermined limit based on the detection value of the G sensor 9. The identification code determination unit 2 and the control unit 3 shift to a collision mode for identification code determination and operation command decoding by the collision signal, respectively, and the received signal from the tuner 1 corresponds to opening of the power window and unlocking of the door lock. To set.

Next, the control flow will be described with reference to the flowchart of FIG. First, when the power is turned on and started, the collision determination unit 10 inputs the detection value of the G sensor 9 in step 100, and determines in step 101 whether the vehicle has a deceleration exceeding a predetermined limit. When the deceleration exceeds the predetermined limit, it is determined that a collision accident has occurred, a collision signal is output, and the identification code determination unit 2 and the control unit 3 enter the collision mode. If there is no collision, in step 102, the identification code determination unit 2 determines the identification code included in the reception signal from the tuner 1 in the normal mode, the control unit 3 decodes the operation command from the reception signal, and the electric motor 4 The corresponding operation is performed by rotating the electric motor 5.

In step 103, in the collision mode, the identification code judging section 2 cancels the identification of the identification code by the collision signal and passes the received signal to the control unit 3. The control unit 3 activates the timer and unlocks the electric motor 4 and drives the electric motor 5 in the power window open direction when there is any received signal. After step 104, the control unit 3 inputs the received signal from the identification code determination part 2, and in step 105, unlocks all seat door locks regardless of the operation command included in the received signal and opens all seat power windows. The electric motor 4 and the electric motor 5 are rotated. Further, the timer 8 is activated to blink the hazards of the flashers 6 and 7 for a certain period of time. In this embodiment, the G sensor 9 and the collision determination unit 10 constitute a collision detection means. Step 103 constitutes an identification cancellation means. Step 105 constitutes a forced unlocking means and a hazard blinking means.

The present embodiment is constructed as described above, and the G sensor 9 is adapted to determine the operating state of the identification code judging section 2 and the control unit 3 by the collision judging result of the collision judging section 10, so that When a collision occurs, the function of judging the identification code for the received signal of tuner 1 and the decoding function of the operation command are canceled, and instead the power window is opened and the door lock is unlocked. Can be unlocked, and rescue after an accident can be done smoothly. In addition, the flashing hazard of the flasher indicates the rescue site.

Next, a second embodiment will be described. In this embodiment, a tuner 11 is used instead of the tuner 1 in the receiving device 200 of the first embodiment shown in FIG. The tuner 11 has a normal reception bandwidth and a wide reception bandwidth wider than the normal reception bandwidth. When the collision signal from the collision determination unit 10 is input, the tuner 11 switches the reception bandwidth to the wide band. Other configurations are similar to those of the first embodiment.

FIG. 3 is a flow chart of the control flow in the above configuration. In steps 200, 201, 202, steps 100, 10 of FIG. 2 in the first embodiment.
Similar to 1 and 102, the collision determination unit 10 detects a vehicle collision from the detection value of the G sensor 9. When there is a collision, a collision signal is output and the receiving device enters the collision mode. When there is no collision, the tuner 11 sets the normal reception bandwidth as the normal mode, the identification code determination unit 2 determines the identification code included in the reception signal from the tuner, and the control unit 3 operates from the reception signal. The command is decoded and the corresponding operation is executed by rotating the electric motor 4 and the electric motor 5.

In the collision mode, the tuner 11 switches the reception bandwidth to the wide reception bandwidth in response to the collision signal in step 203. In step 204, the identification code determination unit 2 also cancels the identification of the identification code by the collision signal. The control unit 3 activates the timer by the collision signal and unlocks the electric motor 4 and drives the electric motor 5 in the power window open direction when there is any received signal.

After step 205, the control unit 3 inputs the received signal from the identification code judging section 2, and in step 206, regardless of the operation command included in the received signal, all seat door locks are unlocked and all seat power windows are turned on. The electric motor 4 and the electric motor 5 are rotated in the opening direction. Further, the timer 8 is activated to blink the flashers 6 and 7 for a certain period of time. Step 20
3 constitutes band expanding means. This also
A transmitter with a different identification code can unlock the door lock.Because the reception bandwidth has been widened, the door lock can be unlocked even using a transmitter of a different vehicle type, and even a transceiver used for contacting rescue. Rescue is even easier because it can be locked or the window can be opened.

[0018]

According to the present invention, when the collision detecting means detects a collision of an automobile, the receiving device cancels the collation of the identification code. Therefore, even if the transmitting means having different identification codes are used, the door lock can be unlocked. It can be locked. This makes it possible to construct a highly complete keele system that is compatible with both accident prevention and post-accident rescue, without the locking door interfering with rescue. Further, in the above-mentioned receiving device, when an automobile collides, the receiving bandwidth is expanded and received, and the operation is set to unlock only regardless of the content of the received signal. However, the door lock can be unlocked. The number of door unlocking means will be increased, and the ease of unlocking will be expanded.
