The invention discloses a vehicle starting method, device and equipment and a storage medium, and relates to the technical field of vehicle control, and the vehicle starting method comprises the steps that when vehicle starting parameters meet vehicle starting conditions, state parameters of a vehicle are obtained; obtaining a vehicle starting strategy according to the state parameters; obtaining a dragging torque based on the starting strategy, and obtaining a motor target torque according to the dragging torque and a motor allowable output torque; according to the method, when the vehicle meets the starting condition, the current vehicle starting strategy is determined according to the vehicle state parameters, and different dragging torques are applied to the vehicle engine based on the different starting strategies so as to drive the engine to rotate. The dragging torque given to the vehicle under different conditions is fully considered in the allowable maximum output power of the motor, the dragging torque is reasonably distributed, the high-efficiency characteristic of the motor is utilized to the maximum extent in the starting stage, and it is guaranteed that the vehicle is successfully started.
本申请公开了一种车辆启动方法、装置、设备及存储介质,涉及车辆控制技术领域,公开了车辆启动方法,包括:在车辆启动参数满足车辆启动条件时,获取车辆的状态参数;根据状态参数得到车辆启动策略;基于启动策略得到拖动扭矩,根据拖动扭矩和电机允许输出扭矩得到电机目标扭矩;基于电机目标扭矩控制发动机转速以启动车辆,该方法通过在车辆满足启动条件时,根据车辆状态参数确定当前车辆启动策略,基于不同的启动策略为车辆发动机施加不同的拖动扭矩以带动发动机转速,在电机允许最大输出功率内充分考虑在不同情况下给到车辆的拖动扭矩,合理分配拖动扭矩,在启动阶段最大限度地利用电动机的高效率特性,保证车辆成功启动。
