A vehicle collision safety control system and control method thereof

Abstract

The invention relates to a vehicle collision safety control system and a control method thereof. The system comprises a collision sensor, a first power supply backup circuit, a second power supply backup circuit, a door lock controller and an airbag controller, wherein the door lock controller and the airbag controller are arranged in a cockpit, and are connected through a high-speed CAN (Controller Area Network) bus; the collision sensor is in communication connection with the airbag controller and can send a signal to the airbag controller; the first power supply backup circuit is connectedwith the door lock controller and supplies power to the door lock controller; and the second power supply backup circuit is connected with the airbag controller and supplies power to the airbag controller. According to the system, when the vehicle is collided, a door lock is automatically unlocked to help a driver escape successfully, and the situation that the door lock cannot be unlocked after an accumulator cell is burst can be avoided, a passive safety system can be safer, and life safety of the driver can be better guaranteed.

Description

technical field [0001] The invention relates to the field of automobile electronics and the field of passive safety of automobiles, in particular to a vehicle collision safety control system and a control method thereof. Background technique [0002] In recent years, after a vehicle collides, the vehicle door lock is not opened in time, causing the driver to fail to get out of danger in time and encounter explosion or burning accidents. Some automobile manufacturers have considered adding a control strategy: when a collision occurs, the door locks are automatically opened. But the current design has a flaw: when a collision occurs, if the collision knocks off the battery power pile head, the power system fails, the entire control strategy will fail completely, and the door lock cannot be automatically unlocked, which cannot effectively help the driver escape. However, in the current traditional vehicle front cabin layout scheme, the battery is generally arranged near the he...
