ENGINE STARTING CONTROL METHOD, ENGINE CONTROL UNIT AND STORAGE MEDIUM

A method for controlling starting of an engine, an engine control unit and a storage medium. The controlling method includes controlling, by an engine control unit, a fuel-oil pump to construct an oil pressure, controlling, by a vehicle body electronic stability program, the entire-vehicle deceleration to be constant, and, by an AT control unit (7), controlling a lock-up clutch (4) to open and a K0 clutch (2) to enter a torque-controlling state; controlling, by a P2 electric motor control unit (8) and the AT-gearbox control unit (7), a rotate speed of a P2 electric motor (3) and a rotate speed of the engine (1) to be synchronized, controlling, by the AT-gearbox control unit (7), the K0 clutch (2) to close, by the engine control unit, controlling the engine (1) to ignite, and activating an engine torque structure; and by the vehicle control unit, increasing the torque demand of the engine (1) according to a driver torque demand, and reducing the torque demand of the P2 electric motor (3) according to an actual engine torque of the engine (1), and, by the AT-gearbox control unit (7), controlling the lock-up clutch (4) to close. The controlling method, by using the effective information interaction among the controllers, realizes the controlling on the starting-up of the engine in the energy recovery process, which may improve the driving safety, and may reduce the risk of under-voltage of the high-voltage battery.
