The invention discloses a control method implemented by an N-gear start-stop system. The control method includes firstly, enabling an engine in a running state to enter an N-gear flameout state under conditions that A, the speed of a vehicle is lower than a threshold value Vf, A1, the rotation speed of the engine is higher than a threshold value Fs1, B, the vehicle is in a brake state, B1, the boosting vacuum degree of a brake system is higher than a threshold value Zf, C, voltage of a storage battery is higher than a threshold value Uf, D, the temperature of water of the engine is higher than a threshold value Ff, and E, an N gear of a transmission is activated and the retention time of the N gear of the transmission is longer than a threshold value Tf after the engine is ignited and started by the aid of a key switch; and secondly, enabling the N-gear start-stop system to transmit 'start instructions' to a starter and the engine until the engine reenters a start state when the engine is ignited and started
