The invention provides a vehicle speed control method, which comprises the steps: obtaining vehicle state information of a target vehicle at a current moment in a driving process of the target vehicle; by adopting a dynamic sliding mode control mode, determining the expected driving torque and the expected braking torque of the target vehicle at the next moment according to the vehicle state information; and according to the determined expected driving torque and the expected braking torque, carrying out acceleration control or deceleration control on the target vehicle at the next moment. According to the method, the expected driving torque and the expected braking torque are determined by adopting the dynamic sliding mode control mode, that is, the specific torque demand value when the expected speed is tracked is determined, and when acceleration or deceleration control is performed on the target vehicle based on the torque demand value, accurate speed control over the target vehicle in the driving process is achieved.
本申请提供了一种车辆速度控制方法,包括:在目标车辆的行驶过程中,获取目标车辆在当前时刻的车辆状态信息;采用动态滑模控制方式,根据车辆状态信息,确定在下一时刻对目标车辆的期望驱动力矩和期望制动力矩;根据确定的期望驱动力矩和期望制动力矩,在下一时刻对目标车辆进行加速控制或减速控制。本申请采用动态滑模控制方式确定了期望驱动力矩和期望制动力矩,即确定了跟踪期望速度时的具体力矩需求数值,基于该力矩需求数值对目标车辆进行加速或减速控制时,实现了对目标车辆在行驶过程中的精准速度控制。
