The invention discloses an automobile door lock control method. The automobile door lock control method comprises the steps that when an automobile door lock switch is moved to a section of continuous area between the locking state and the unlocking state, an automobile door locking signal and an automobile door unlocking signal are output at the same time; under the locking state, if an unlocking signal of one automobile door is received while the automobile door locking signal of the corresponding automobile door is not received, an automobile door unlocking control signal is output, and if the falling edge of the locking signal of the other automobile door and the rising edge of an unlocking signal of the other automobile door are detected, normal unlocking is confirmed; under the unlocking state, if one automobile door locking signal is received while the automobile unlocking signal of the corresponding automobile door is not received, an automobile door locking control signal is output, and if the falling edge of the unlocking signal of the other automobile door and the rising edge of the locking signal of the other automobile door are detected, normal locking is confirmed. According to the automobile door lock control method, whether the signal change is an action order or a loop fault can be accurately distinguished according to the locking and unlocking signals, and therefore the automobile lock locking and unlocking can be accurately executed, 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] 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 that the corresponding signal is not received; image 3 A schematic diagram of an existing door lock switch state feedback loop is shown, wherein when the door lock switch moves to position A1, it indicates that the door is in a locked state, and when it moves to position A2, it indicates that the door is in an unlocked state. like figure 1 and image 3 As shown, in the existing door lock control loop, the main driver's door and the passenger's door only output the main driver's door unlock signal Munl ( figure 1 is ...
