VEHICULAR DOOR LOCK CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To reliably perform unlocking, locking and locking restricting operation of a vehicular door lock control device by providing a control means to change the timing to turn on two relays among three relays by a prescribed time. SOLUTION: An S/L motor is driven in the U/L direction by turning on output voltage of a terminal B after prescribed time T1 by driving an N/L motor in the U/L direction by turning on output voltage of a terminal C. A locking mechanism is put in an U/L state when turning off the output voltage of the terminal B after passing prescribed time T3 by turning off the output voltage of the terminal C after passing prescribed time T2. There is a fear of operating the S/L motor in the S/L direction by the output voltage from the terminal C when impressing the output voltage of the terminal B since there is generally an individual difference in required time of mechanical operation of contact points arranged in relays, but a malfunction can be reliably prevented by delaying the output timing of the terminal B by the prescribed time T1 more than the terminal C and also setting the prescribed time T1 longer than a nominal error. Operation to transfer to an N/L state and an S/L state is also the same.
