VEHICLE DOOR CLOSING CONTROL DEVICE INCLUDING DOOR CLOSING SECURITY CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a vehicle door closing control device capable of specifying whether a cause of an accident that a door is opened during travelling exists in a door closing control circuit or a door closing security circuit by retaining traces in the case wherein a door opening switch is pushed during the travelling by using only hard sequence circuit of a relay.;SOLUTION: A circuit, in which a relay for opening the door is not excited even if a door opening switch is pushed during the travelling of a vehicle (at a speed of 5 km/h or more) by using a speed security relay to be operated during the traveling of the vehicle (at a speed of 5 km/h or more), and a circuit, in which lighting of a travelling display lamp is maintained even if the vehicle stops (or travels at a speed of 5 km/h or less) in the case wherein the door opening switch is pushed during the travelling of the vehicle (at a speed of 5 km/h or more), are formed of the only hard sequence circuit of the relay. With this structure, an evidence of wrong operation that the door opening switch is pushed during the travelling is retained, and it becomes easy to specify whether a cause of the accident that the door is opened during the travelling exists in the door closing control circuit or in the door closing security circuit, and a cause can be quickly investigated.;COPYRIGHT: (C)2012,JPO&INPIT
