The invention discloses a vehicle engine starting method and device, equipment, a storage medium and a product, and relates to the technical field of vehicle control, and the method comprises the steps that the current state of a target vehicle is obtained, and the starting mode of an engine in the target vehicle is determined according to the current state; determining a motor compensation torque of the target vehicle based on the starting mode, and determining a final demand torque of a driving motor and a compression demand torque of a clutch according to the motor compensation torque; the initial torque of the driving motor is increased by preset torque, and the preset torque is determined according to the clutch oil temperature of the target vehicle; and the torque of the driving motor is adjusted to reach the final required torque, and the torque of the clutch is adjusted to reach the pressing required torque to start the engine. The starting method that the driving motor provides power and the clutch slips to drive the engine is designed, torque compensation is conducted through the driving motor, the rotating speed and the torque of the engine can stably reach required values, and the whole vehicle cost is reduced while driving smoothness is ensured.

    本申请公开了一种车辆发动机启动方法、装置、设备、存储介质及产品,涉及车辆控制技术领域,所述方法包括:获取目标车辆的当前状态,并根据当前状态确定目标车辆中发动机的启动方式;基于启动方式确定目标车辆的电机补偿扭矩,并根据电机补偿扭矩确定驱动电机的最终需求扭矩和离合器的压紧需求扭矩;将驱动电机的初始扭矩提升预设扭矩,预设扭矩根据目标车辆的离合器油温确定;调整驱动电机的扭矩到达最终需求扭矩、调整离合器的扭矩到达压紧需求扭矩以启动发动机。本申请设计了以驱动电机提供动力、离合器打滑带动发动机的启动方法,并由驱动电机进行扭矩补偿,使发动机的转速和扭矩能平稳达到需求值,确保了驾驶平顺性的同时降低了整车成本。
