The invention discloses a vehicle sliding feedback torque adjusting method, device and equipment and a storage medium. The method comprises the steps that whether a vehicle is in a sliding feedback state currently or not is judged; when it is determined that the vehicle is in the sliding feedback state, parameters of the vehicle during sliding are determined based on the current vehicle speed, and the parameters comprise a sliding feedback torque initial value, a sliding feedback torque upper limit value, a motor maximum available feedback torque value, a battery maximum allowable feedback torque value, the current deceleration of the vehicle and the current expected driving deceleration; based on the parameters, a sliding feedback torque target value of the vehicle in the current control period is calculated; and enabling the sliding feedback torque of the vehicle in the current control period to be close to the sliding feedback torque target value at a certain step length so as to adjust the sliding feedback torque of the vehicle. The stable deceleration of the vehicle is guaranteed, the sliding feedback recovery energy is improved, the driving mileage of the whole vehicle is increased, meanwhile, the active braking action frequency is reduced, and the driving experience is improved.
本发明公开了一种车辆滑行回馈扭矩调整方法、装置、设备及存储介质,其中该方法包括步骤:判断车辆当前是否处于滑行回馈状态;当确定车辆处于滑行回馈状态时,基于当前车速,确定车辆滑行时的参数,所述参数包括:滑行回馈扭矩初始值、滑行回馈扭矩上限值、电机最大可用回馈扭矩值、电池最大允许回馈扭矩值、当前车辆的减速度和当前期望的行驶减速度;基于所述参数,计算车辆当前控制周期的滑行回馈扭矩目标值;将车辆当前控制周期的滑行回馈扭矩以一定的步长靠近所述滑行回馈扭矩目标值,以调整车辆滑行回馈扭矩。本申请保证车辆减速度平稳,提高了滑行回馈回收能量,有助于提升整车续驶里程,同时也减少了主动刹车动作频率,提升了驾驶体验。
