The invention discloses a vehicle deceleration control method, device and equipment, a storage medium and a program product, relates to the technical field of automobiles, and discloses the vehicle deceleration control method, device and equipment, the storage medium and the program product, and the method comprises the steps that the real-time vehicle speed and the target vehicle speed are obtained; when the target vehicle speed is smaller than the real-time vehicle speed, a vehicle deceleration instruction is obtained, and the target pressure buildup pressure of a braking system is determined based on the vehicle deceleration instruction; and braking energy is recycled based on the target pressure buildup pressure of the braking system, and the actual deceleration of the vehicle is obtained. According to the method, the negative torque and the braking requirement which can be provided by the motor are judged, when the negative torque provided by the motor cannot meet the whole vehicle deceleration request, active pressurization is conducted, the insufficient deceleration requirement is supplemented, when the negative torque provided by the motor meets the whole vehicle deceleration request, complete motor braking is conducted, and therefore energy recovery is increased, the whole vehicle endurance is improved, and the power consumption is reduced. Meanwhile, active pressurization frequency of the braking system is reduced and service life of the braking system is prolonged.
本申请公开了一种车辆减速控制方法、装置、设备、存储介质及程序产品,涉及汽车技术领域,公开了车辆减速控制方法、装置、设备、存储介质及程序产品,包括:获取车辆实时车速与目标车辆车速;当所述目标车辆车速小于所述车辆实时车速时,获取车辆减速指令,基于所述车辆减速指令确定制动系统目标建压压力;基于所述制动系统目标建压压力进行制动能量回收,得到车辆实际减速度。本申请判断电机所能提供负扭矩和制动需求,当电机所提供的负扭矩无法满足整车减速请求时,进行主动加压,补足不足的减速需求,当电机所提供的负扭矩满足整车减速请求时,完全电机制动,从而增加能量回收提高整车续航,同时减少制动系统主动加压频次提高制动系统寿命。
