Title:
ENGINE STARTING CONTROL METHOD, ENGINE CONTROL UNIT AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/174681
Kind Code:
A1
Abstract:
An engine starting control method, an engine control unit and a storage medium. The control method comprises: an engine control unit controlling a fuel pump to establish oil pressure, an electronic stability program controlling the deceleration of a vehicle to be constant, and an AT control unit (7) controlling a lock-up clutch (4) to open and controlling a K0 clutch (2) to enter a torque control state; a P2 motor control unit (8) and the AT control unit (7) controlling a P2 motor (3) to be synchronized with an engine (1) in terms of rotation speed, the AT control unit (7) controlling the K0 clutch (2) to close, and the engine control unit controlling the engine (1) to ignite and activating an engine torque architecture; and a hybrid control unit increasing the torque requirement of the engine (1) according to the torque requirement of a driver and same decreasing the torque requirement of the P2 motor (3) according to the actual engine torque, and the AT control unit (7) controlling the lock-up clutch (4) to close. By means of the control method, control over the starting of an engine in an energy recovery process is achieved by means of effective information exchange between control units, such that driving safety can be improved, and the risk of insufficient voltage of a high-voltage battery can be decreased.
