Description

Automotive door lock prevention device.

The present invention relates to a door lock preventing device for a vehicle, and more particularly, to prevent the door from being locked by the impact force caused by the collision of the car equipped with the auto door lock system to facilitate the escape of the rider.

Conventionally, it is installed as a manual type that individually controls the way of opening and closing the angler of a car. The door is opened by using keys in the driver's seat or the passenger seat, and the corresponding door is opened by pressing and pulling the locking lever provided in each door. It is a destructible configuration.

Such manual type door opening / closing device can be used when the driver opens the driver's door using the key and the driver is provided inside the passenger seat and the rear door to release the locking lever. When getting off, all the passengers except the driver get off and the driver presses the locking lever of each door in the interior of the car to switch to the locked state and gets off to lock the driver's door using the key.

In the case of this manual type, the driver has to open four doors and lock them.

In order to eliminate the trouble of the manual type as described above, an auto door lock that controls the opening and closing of the entire door by operating a locking lever provided in the driver's angle using a key in the driver's seat or operating a locking lever provided in the driver's seat. It has been developed and used by mounting it.

In the case of the above-mentioned auto door lock, if the driver's door is opened with a key, the whole door is opened and after getting off, the door is locked by controlling the driver's door with the key, which is quite convenient. .

However, in the case of such an auto door lock, if a collision occurs while the car is driving, and the actuator that operates the auto door lock is damaged due to the impact force, the door is not opened and the passengers cannot escape quickly due to the loss of life. Serious accidents such as

In particular, if there is a child occupant among the occupants, when the auto door lock is locked in preparation for accidental behavior (such as opening the door) of children, opening of the door becomes more difficult and it is impossible to escape.

Accordingly, the present invention has been made to solve the above problems, and it is an object of the present invention to keep the auto door lock open even if a collision or bump occurs during driving while the auto door lock is locked. .

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the present invention for achieving the above object will be described.

1 is a block diagram showing a door lock preventing device of the present invention, Figure 2 will be described together as a control flow chart of the door lock preventing device of the present invention.

The door lock preventing device 15 of the present invention uses a vehicle speed sensor 10 for detecting a current speed of a vehicle, a deceleration sensor 11 for detecting a deceleration state, and a shock sensor 12 for detecting a collision or collision situation. It is possible to provide an easy escape by controlling the actuator 13 of the auto door lock to be in an unlocked state where a collision situation will occur.

The detection values of the vehicle speed sensor 10, the deceleration sensor 11, and the impact sensor 12 are input to the actuator 13 (connected to a separate controller 14 associated with the auto door lock) to control the actuator 13 when an abnormality occurs. To help.

The controller 14 may be included in the integrated control device provided in the vehicle equipped with the auto door lock without being provided separately.

The controller 14 receives the detected values of the sensors 10, 11, and 12, calculates the vehicle speed, the deceleration value, and the impact value, and sends a signal to the actuator 13 when the controller 14 exceeds the preset value. To prevent this from happening.

An embodiment of the present invention configured as described above is illustrated in FIG. 2, which will be described in detail below.

When the vehicle runs, the vehicle speed sensor 10, the deceleration sensor 11, and the impact sensor 12 detect a current state and input the same to the controller 14.

The controller 14, which receives various data from each of the sensors 10, 11, and 12, comprehensively analyzes the input values, calculates them, and continuously monitors whether the calculated values are above the set values. Proceed.

When an abnormal phenomenon with a deceleration value or an impact value greater than the value set by the monitoring performed as described above occurs, the controller 14 sends a signal to the actuator 13 to control the door to be unlocked.

That is, when the vehicle is driven, the controller 14 receives the detected values from the sensors 10, 11, and 12, and calculates the vehicle speed, deceleration, and impact value;

If the deceleration value is greater than the set value, check the shock value again. If the shock value is also greater than the set value, the controller 14 outputs a signal to the actuator 13 to keep each door unlocked to prevent collision and collision. Even if the same accident occurs, problems such as impossibility of escape due to the door lock state are prevented.

When any one of the deceleration value and the impact value is smaller than the set value, the signal output to the actuator 13 is prevented.

The present invention as described above has the effect of contributing to the improvement of safety, such as to reduce the loss of life by making it possible to quickly escape by opening the door in the event of a collision, collision occurring during the car driving.
