Beschreibung
Zusammenfassung:	The invention provides an engine start control system for a hybrid vehicle. The system comprises a clutch state detector, a vehicle controller, an engine start motor and a clutch, wherein the clutch state detector detects the state of the clutch, and sends a clutch separation signal to the vehicle controller when the clutch is separated, and the vehicle controller sends an engine allowing start signal to control an engine start motor to be electrified, so that the engine start motor is started. The state of the clutch is detected by the clutch state detector, and the detected clutch state is sent to the vehicle controller; when the state of the clutch is in a separation state, the vehicle controller can control the engine start motor to be started. If the clutch is in a connecting state, the vehicle controller can not allow the engine start motor to be electrified; thereby ensuring that the engine start motor is started only when the clutch is in a separation state, otherwise the engine start motor is not sta
