Many people are used to directly ignite after being screwed up after a key is inserted when starting the automobile, and the operation is clean and convenient on the surface and saves time, but the automobile is damaged in practice.

The correct starting mode of the automobile is to twist the automobile from one gear to the next gear and to ignite and start the automobile in a step-by-step progressive mode. After the key is inserted into the key hole, the key is screwed from the Lock file to the Acc file and then stays for about 1-2 seconds, and at the moment, the sound of the power-on of the electrical equipment can be heard.

when the light intensity received by the photoelectric converter (14) changes from small to large, the controller (15) switches on the auxiliary equipment circuit, controls the lifting cylinder (31) to extend out, maintains the Acc damping time, and returns to the step c;

if the light intensity received by the photoelectric converter (14) changes from large to small, all the electric equipment circuits except the accessory equipment circuit are closed, and the step c is returned;

receiving On light intensity threshold value signal, judging light intensity change direction, if:

when the light intensity received by the photoelectric converter (14) changes from small to large, the controller (15) is connected with all the electric equipment circuits outside the accessory equipment circuit, controls the lifting cylinder (31) to extend out, maintains the On damping time, and returns to the step c;

if the light intensity received by the photoelectric converter (14) changes from large to small, the controller (15) does not make any reaction and returns to the step c;

and receiving a Start light intensity threshold signal, and starting the engine.
