or,
when the controller (201) counts in the first stage and the counted time does not reach the designated time value T1, the owner does not use the owner's mobile phone (3) to dial the phone number of the communication device (205), and the step is changed to execute F6;
F2. the automatic power-off device (2) detects whether an engine of the automobile is started or not and whether the automobile runs or not through the vibration sensor (202) and the air pressure sensor (203), and the detection method comprises the steps of detecting vibration generated when the engine runs through the vibration sensor (202), detecting vibration generated when the automobile runs through the vibration sensor (202), and detecting the change of air pressure in a compartment of the automobile during running through the air pressure sensor (203);
F3. when the automobile stops running and the engine is turned off, the automatic power-off device (2) cannot detect vibration and air pressure change through the vibration sensor (202) and the air pressure sensor (203), and the controller (201) in the automatic power-off device (2) immediately starts second-stage timing;
F4. during the time that the controller (201) performs the second-stage timing and the timing time does not reach the designated time value T2, if the automobile engine is started or the automobile continues to run, the automatic power-off device (2) detects that the automobile engine is restarted or the automobile continues to run through the vibration sensor (202) and the air pressure sensor (203), the controller (201) immediately stops the second-stage timing and goes to step F2, otherwise, the controller goes to step F5; the time value T2 ranges from 15 seconds to 5 minutes, preferably 1 minute;
F5. when the controller (201) counts time in the second stage and the counted time reaches the designated time value T2, the automobile is completely stopped, the automatic power-off device (2) is immediately restarted and returns to the initial state, and the step A1 is executed;
F6. when the controller (201) counts in the first stage and the counted time reaches a designated time value T1, the controller (201) controls the relay (204) to enable the equipment on the automobile connected with the relay (204) to perform a preset anti-theft operation, so that the automobile can not continue to normally run.
