Enter step 5；
Step 2, described AD sampling module starts the sample voltage value of its caching of detection, in Preset Time, it is judged that described
Whether sample voltage value has voltage pulsation to change；Change without voltage pulsation, then enter lower step, if there being voltage pulsation
Change, then enter step 5；
Whether step 3, starts electronic gyroscope, have the angle of persistence to turn according to described electronic gyroscope detection vehicle
Become shock wave；Without the angle change shock wave of persistence, then enter lower step, if the angle change vibrations of persistence
Ripple, then enter step 5；
Step 4, starts GPS locating module, after GPS completes location, whether detects car speed according to GPS locating module
Always more than zero, and persistence is had to change；If speed is always more than zero, and has persistence to change, then enter step 5, if
Speed is the most always more than zero, and changes without persistence, then enter step 6；
Step 5, exports vehicle " starting state " signal；
Step 6, exports vehicle " inactive state " signal.
Its further technical scheme is: described preset value voltage is 13.5V.
