The invention provides a vehicle longitudinal motion control unit and a control method. A control unit for a vehicle including a first axle motor coupled with a first axle and a second axle motor coupled with a second axle includes a distribution module configured to distribute a first torque for the first axle motor such that the first axle motor operates only in a first or second quadrant, and to distribute a second torque for the second axle motor such that the second axle motor operates only in a second or first quadrant, the second shaft motor only works in the third quadrant or the fourth quadrant; the acquisition module is configured to acquire a target change of longitudinal movement of the vehicle and a corresponding control parameter; and the decision module is configured to decide a control strategy of the first shaft motor and the second shaft motor according to the target change and the corresponding control parameters, and the control strategy comprises that the target change of longitudinal acceleration or deceleration of the vehicle is achieved through cooperation between the first shaft motor and the second shaft motor working in different quadrants.

    本发明提供了一种车辆纵向运动控制单元和控制方法。车辆包括与第一轴耦接的第一轴电机和与第二轴耦接的第二轴电机,所述控制单元包括:分配模块,配置成为第一轴电机分配第一扭矩,以使得第一轴电机仅在第一或第二象限工作,以及为第二轴电机分配第二扭矩,以使得第二轴电机仅在第三或第四象限工作;获取模块,配置成获取车辆的纵向运动的目标变化以及相对应的控制参数;以及决策模块,配置成根据所述目标变化以及相应的控制参数来决策第一轴电机和第二轴电机的控制策略,其中,所述控制策略包括:通过工作在不同象限的第一轴电机和第二轴电机之间的配合来实现车辆纵向加速或减速的目标变化。
