Door lock control system of intelligent automobile body controller

Abstract

The invention discloses a door lock control system of an intelligent automobile body controller. The door lock control system drives a door lock motor via a relay, controls the door lock motor to rotate in different directions, and can enable a door lock to be unlocked and locked. The door lock control system further has the functions of collision unlocking control and overheat protect control, in case of collision, locking operation via remote control or a front-row lock rod is shielded and can only be performed after one ignition cycle, and when door lock operation is in an overheat protect state, door lock operation is determined according to the fact whether the door lock operation is triggered by a user or triggered automatically. The door lock control system of the intelligent automobile body controller is high in safety performance, the service life of a door lock mechanism is prolonged, and safety of persons in an automobile and safety of the automobile are guaranteed.

Description

technical field [0001] The invention relates to the field of vehicle body controllers, in particular to a door lock control system of an intelligent vehicle body controller. Background technique [0002] The intelligent body controller (hereinafter referred to as BCM) integrates mainly by collecting all the signals required for the control of the body, according to the corresponding control requirements, after being judged and processed by the BCM, it drives the corresponding equipment, so as to realize the intelligent control of the body. It mainly includes comprehensive control of door lock system, window system, exterior light system, interior light system, RKE system, security system, auxiliary system and other subsystems. [0003] The general functional scope of the BCM door lock system includes the following aspects: (1) All doors are locked; (2) The driver's door is unlocked separately (single point entry SPE); (3) Front and rear passenger doors are unlocked (exce...

AI Technical Summary

Problems solved by technology

For example, in a vehicle collision accident, the control of the door lock is extremely critical. Once the door lock is out of control, it may cause people in the car to be trapped and difficult to escape.

Some door lock controllers in the prior art, after a collision, the door lock is automatically unlocked, but the body after the collision may still run at a faster speed. Once the speed locking condition is reached, the central control lock is pressed again to make the car It may be locked again, causing the occupants in the car to be unable to escape in time, endangering life safety

Another example is that the motor that controls the door lock is prone to heat during the frequent opening and closing process. If the heat is not dissipated in time, the motor will overheat. If you continue to open and close the door lock at this time, it will inevitably burn out Bad motor or more serious problems, thus affecting driving safety

It can be seen that the door lock control system of the prior art still has problems such as low safety performance, inability to perform overheating protection of the door lock motor, and poor reliability, which affects the safety of the vehicle body and personnel in the car, and is difficult to meet the increasingly complex door lock requirements.
