The invention provides an engine start and stop system, which comprises a start and stop controller, a storage battery, a starter, a stop-triggering data detection module, a start-triggering data detection module and a vehicle body communication network. According to the engine start and stop system disclosed by the invention, a real-time road condition detection module which is used for detecting the current vehicle position and the position of the nearest traffic light in a vehicle running direction is added in the stop-triggering data detection module, moreover, a stop-triggering condition of double quotation marksthe distance between the current vehicle position and the position of the nearest traffic light in the vehicle running direction is less than or equal to a preset stop distance double quotation marks is added into the start and stop controller, the start and stop controller prohibits an engine from stopping when the distance is greater than the preset stop distance, so that ineffective start and stop are prevented, and thereby the engine start and stop system saves fuel and reduces the emission of harmful gas. In addition, the invention also provides an engine start and stop control method.
