And when the first difference value is smaller than the first threshold value, the second difference value is smaller than the second threshold value or the rotating speeds of the transmission, the motor and the engine are not normally reset to zero, a stop early warning instruction is generated to stop the start and stop detection of the engine, and the single detection result is determined to be a single detection failure.
