Control system and method for vehicle door lock

Abstract

The invention discloses a control system and method for a vehicle door lock. The system comprises a vehicle-mounted T-Box, a standby line, a central gateway, a vehicle body area controller, a door lock control module and a user terminal, wherein the vehicle-mounted T-Box, the standby line, the central gateway, the vehicle body area controller and the door lock control module are arranged in a vehicle, and the user terminal establishes communication connection with the vehicle-mounted T-Box; when the vehicle-mounted T-Box judges that the vehicle body area controller breaks down, BDCM fault information is sent to the user terminal; the user terminal responds to the received BDCM fault information and displays a standby unlocking key on a vehicle unlocking interface; the user terminal generates a standby unlocking instruction and sends the standby unlocking instruction to the vehicle-mounted T-Box in response to the operation that the user clicks the standby unlocking key; and the vehicle-mounted T-Box forwards the received standby unlocking instruction to the door lock control module through a standby line so as to control the door lock control module to execute an unlocking operation. By the adoption of the embodiment, it can be guaranteed that the vehicle door lock can be normally unlocked when the vehicle body area controller breaks down, and the use convenience of the vehicleis improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a control system and method for a vehicle door lock. Background technique [0002] With the development of intelligent networking of automobiles, the electrical and electronic architecture of automobiles is gradually transitioning from distributed to domain-centralized, and more and more functions are integrated into the domain controller. If a fault occurs inside the controller, most functions will be paralyzed and unable to perform. The inventor found in the process of implementing the present invention that the unlocking of vehicle door locks is generally controlled by a body domain controller integrated with functions such as unlocking and opening the door. Once the body domain controller fails, the vehicle cannot be unlocked and opened. , will cause great inconvenience to users.
