9. A method for controlling a one-button start and remote door lock of a passenger car according to claim 8, characterized in that: The specific steps of step S2 are: 1) The controller determines the state of the K1 brake switch. When the K1 brake switch is turned on, the controller pin 11 is suspended; when the driver presses the start switch K4 for the first time, the start switch K4 lights up with a green indicator light, and the controller pin 1 outputs ACC power for the vehicle's electrical equipment; when the driver presses the start switch K4 for the second time, the start switch K4 lights up with a red indicator light, and the controller pin 2 outputs ON power for the vehicle's electrical equipment; when the driver presses the start switch K4 for the third time, the controller pins 1 and 2 do not output power, and the vehicle is powered off; when the power is off, the ON power is turned off first, and then the ACC power is turned off after a delay of 3S; The vehicle is powered on in the order of OFF→ACC→ON→OFF in a reciprocating cycle; 2) The controller determines the state of the K1 brake switch. When the K1 brake switch is closed and grounded, the driver steps on the brake and presses the start switch K4 at the same time. The start switch K4 lights up the red indicator light and the blue backlight at the same time. The controller pin 1 outputs ACC electricity, the pin 2 outputs ON electricity, and the pin 3 outputs START electricity. The start relay J1 coil end is energized, the start relay J1 contact is closed, and the starter M1 receives the 24V voltage signal through the fuse F1. Then the starter M1 installed on the engine works and starts the engine. 3) Pin 9 and pin 10 of the controller read the engine speed signal through the speed sensor S1 and the CAN bus; when the vehicle is successfully started, the controller detects that the speed is lower than 5Km / h, press the start switch K4, and the whole vehicle is powered off; when the power is off, the ON power is cut off first, and then the ACC power is cut off after a delay of 3S.
