The invention discloses an automobile door lock control method. The method comprises the steps that when automobile doors are in a locked state, an automobile door unlocking control signal is output if an unlocking signal of one automobile door is received while an automobile door locking signal of the corresponding automobile door is not received; after the automobile door unlocking control signal is output, if the falling edge of a locking signal of the other automobile door is detected firstly and the rising edge of the unlocking signal of the other automobile door is detected later the normal unlocking is confirmed; when the automobile doors are in an unlocked state, an automobile door locking control signal is output if an automobile door locking signal is received while the unlocking signal of the corresponding automobile door is not received; after the automobile door locking control signal is output, if the falling edge of the unlocking signal of the other automobile door is detected firstly and the rising edge of the locking signal of the other automobile door is detected latter, the normal locking is confirmed. According to the method, at least whether the signal change is an action order or a loop fault can be accurately distinguished according to the unlocking signal and the locking signal, and therefore the door lock can be accurately unlocked and locked, and misjudgment can be prevented.
Description
technical field [0001] The invention relates to the field of vehicle body control, in particular to an automobile door lock control method. Background technique [0002] The door lock control circuit mainly sends the door opening and closing state signal to the body control module (BCM) through the central control switch of the main driver, the remote control key, and the switch handles on the side of the main driver and the co-driver, so that the BCM outputs the door lock or lock correspondingly. The door unlock control signal is sent to the relay, and then the relay controls the main driver's door, passenger door, and rear seat door lock motors to open and close the doors. [0003] figure 1 It shows the action principle of the existing door lock control loop. The hollow circle in the figure represents the unlocking and locking command, and the solid circle represents the confirmation of the switch state. ON means that the corresponding signal is received, and OFF means th...
