The invention discloses a hybrid electric vehicle engine sliding friction starting control method and a device. The method comprises the following steps: a rotation speed of a gearbox input shaft is acquired, and if the rotation speed of the gearbox input shaft is larger than an idle speed of the engine, a clutch is controlled to enter a first rapid combination stage; after the first rapid combination stage of the clutch is finished, the clutch is controlled to enter a slow combination stage; whether a brake vacuum pump signal or an air conditioner enabling demand signal is received is judged; if yes, a torque instruction of the motor is generated according to demand torque of the motor, and when the real-time rotation speed of the motor is larger than the idle speed of the engine, the clutch is controlled to be separated quickly; and if not, the torque instruction of the motor is generated according to the demand torque of the motor, and when the real-time rotation speed of the engine is larger than the idle speed of the engine, the engine is controlled to fire and the clutch is controlled to enter a second quick combination stage until complete combination. Different modes are adopted in different working conditions to control the engine and the clutch, and the operation is simple and reliable.
