Abstract

The invention provides a car door locking reminding system. A key insertion switch, an alarm device, a door touching switch, an unlocking signal switch, a locking signal switch, an ignition signal switch, a coil of an unlocking relay and a coil of a locking relay are connected with a car body controller. A left door lock motor is in parallel connection with a right door lock motor, and then the left door lock motor and the right door lock motor are in series connection with a storage battery through a pair of contacts of the unlocking relay and a pair of contacts of the locking relay; when the coil of the unlocking relay is charged, the unlocking relay acts to enable the left door lock motor and the right door lock motor to form an inverse circuit with the storage battery; when the coil of the locking relay is charged, the locking relay acts to enable the left door lock motor and the right door lock motor to form a forward circuit with the battery. The invention further provides a car door locking reminding control method. The car door locking reminding system and control method have the advantage of being high in safety.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a door lock reminding system and a control method. Background technique [0002] Drivers often run into this situation when they drive. They are anxious to drive to work, but they often forget to lock the car door after getting off the car and closing the car door in a hurry. The unlocked car door causes a great potential safety hazard. [0003] The car door locking reminder system of the prior art utilizes the micro switch in the keyhole of the ignition switch to detect whether the car key is pulled out, and sends an alarm to remind the driver that the car door is unlocked after the car key is pulled out and the car door is opened for a certain period of time. [0004] There is following shortcoming in prior art: [0005] 1. The precondition for alarming is that the car key is pulled out. In fact, in a hurry, it often happens that the driver turns off the engine but forgets to ...
