The invention discloses a vehicle brake pedal force compensation method and device and a vehicle. The compensation method can comprise the steps that when a virtual pedal force compensation function of the vehicle is activated, a virtual pedal force compensation numerical value and an energy recovery target request value are obtained and summed, and an actual energy recovery value is obtained; wherein the energy recovery target request value is related to the pedal travel; the virtual pedal force compensation value is related to the virtual pedal force compensation function. Through the mode, the actual energy recovery value when the virtual pedal force compensation function of the vehicle is activated can be calculated, so that the deceleration of the whole vehicle can be accurately calculated, and the problem of hysteresis of the deceleration of the whole vehicle when the virtual pedal force compensation function is applied is solved.
本申请公开了车辆制动踏板力补偿方法、补偿装置及车辆,其中,补偿方法可以包括:车辆的虚拟踏板力补偿功能被激活时,获得虚拟踏板力补偿数值和能量回收目标请求值,并进行求和,得到实际能量回收值;其中,能量回收目标请求值与踏板行程相关;虚拟踏板力补偿数值与虚拟踏板力补偿功能相关。通过上述方式,本申请可以计算出车辆的虚拟踏板力补偿功能被激活时的实际能量回收值,从而可以准确计算整车的减速度,以解决在应用虚拟踏板力补偿功能时整车减速度存在滞后性的问题。
