Abstract

The invention discloses an automobile door lock system, which comprises an automobile starting control unit, a power supply and an automobile body control module, wherein the output end of the automobile body control module is connected with a running state lock and a stopping state lock by a door lock control relay module. In the driving state of an automobile, the automobile body control modulereceives a power failure signal, and controls the running state lock to be unlocked. The structure and the method have the advantages that: when the automobile collides in running to cause a power failure, the running state lock can be automatically unlocked, so a driver and passengers can conveniently escape and are prevented from being trapped on the automobile; and 2, in a stopping state, a power maintenance scheme is not required after an automobile door lock is locked, namely the automobile door lock is still kept in a locked state in a power-free state to avoid the over-high power consumption of the whole automobile causing power feed.
