The invention relates to the technical field of vehicles, and discloses a vehicle braking control method, device and equipment and a storage medium, and the method comprises the following steps: determining a braking demand torque of a vehicle according to current driving data, ramp data and a current gear of the vehicle; the target negative torque of the driving system is determined according to the target charging power allowed by the battery and the current rotating speed of the motor, the target charging power allowed by the battery refers to the maximum charging power allowed by the battery at the current moment, and the current rotating speed of the motor refers to the rotating speed of the driving motor at the current moment; when the absolute value of the braking demand torque is larger than the absolute value of the target negative torque of the driving system, in-cylinder braking is controlled; by means of the mode, when it is determined that the absolute value of the braking demand torque is larger than the absolute value of the target negative torque, the engine is called to conduct in-cylinder braking, so that supplementation of the deceleration torque is achieved, the braking accuracy and stability can be effectively improved, and the braking effect under different vehicle weights is consistent.
本发明涉及车辆技术领域,公开了一种车辆制动控制方法、装置、设备及存储介质,该方法包括:根据车辆的当前行驶数据、坡道数据以及当前挡位确定车辆的制动需求扭矩;根据电池允许的目标充电功率、电机的当前转速确定驱动系统的目标负扭矩,该电池允许的目标充电功率指的是电池在当前时刻允许的最大充电功率,该电机的当前转速指的是驱动电机在当前时刻的转动速度;在制动需求扭矩的绝对值大于驱动系统的目标负扭矩的绝对值时,控制进行缸内制动;通过上述方式,在确定制动需求扭矩的绝对值大于目标负扭矩的绝对值时调用发动机进行缸内制动,以实现对用于减速扭矩的补充,从而能够有效提高制动的准确性和稳定性,使得不同车重下制动效果一致。
