The invention relates to the technical field of unmanned driving, in particular to a vehicle speed control method and system for an unmanned collision target platform vehicle. The method comprises thefollowing steps of: receiving predetermined vehicle speed track information of a target platform vehicle; calculating a driving force or a braking force required by the speed change of the target platform vehicle according to the predetermined vehicle speed track information; independently controlling the working state control mode according to the driving force or braking force value, and outputting corresponding torque and rotating speed and coordination control over the braking force; the system comprises a vehicle controller, a motor controller and a brake controller. According to the embodiment of the invention, the method is executed through the system, and the precision of tracking the speed of the platform vehicle is improved through the coordinated control of different working states, output torques and rotating speeds of the double motors and the braking force of the braking controller; motion interference between the two motors is avoided, and energy consumption of the system is reduced.

    本发明涉及无人驾驶技术领域,尤其涉及一种无人驾驶碰撞目标平台车的车速控制方法及系统。所述方法包括以下步骤:接收目标平台车预定车速轨迹信息;根据所述预定车速轨迹信息计算所述目标平台车车速变化所需要的驱动力或者制动力;根据所述驱动力或者制动力值,工作状态控制模式进行单独控制,输出对应的转矩、转速以及对制动力的协调控制;所述系统包括车辆控制器、电机控制器和制动控制器;本发明实施例通过所述系统执行上述方法,对双电机不同工作状态、输出转矩、转速以及对制动控制器制动力的协调控制,提高跟踪平台车车速的精确性;避免双电机之间产生运动干扰,节省系统能量消耗的效果。
