The embodiment of the invention relates to the technical field of vehicle control, and discloses a vehicle control method based on slip rate, comprising: acquiring driving state information of a target vehicle; reference wheel speed information of each wheel is calculated according to the rolling radius and the angular speed, and the initial slip rate of each wheel is determined based on the reference wheel speed information and a wheel speed-slip rate mapping table; detecting and recognizing the target vehicle to obtain vehicle body posture information, if the vehicle body posture information is steering driving information, processing the vehicle body posture information to obtain steering gradient information, transverse acceleration and longitudinal acceleration, and then determining the final slip rate and controlling the vehicle. According to the vehicle control method based on the slip rate, not only is the vehicle slip rate data in the straight driving state considered, but also the slip data of the target vehicle in the steering process is updated to obtain the slip rate data more conforming to reality, and the slip rate data is provided for the vehicle ECU for precise control.
本发明实施例涉及车辆控制技术领域,公开了一种基于滑移率的车辆控制方法,包括:获取目标车辆的行驶状态信息;根据滚动半径和角速度计算得到各个车轮的参考轮速信息,并基于参考轮速信息与轮速‑滑移率映射表来确定各个车轮的初始滑移率;对目标车辆进行检测识别以得到车身姿态信息,若车身姿态信息为转向行驶信息,对车身姿态信息进行处理以得到转向梯度信息、横向加速度和纵向加速度,进而确定最终滑移率并进行车辆控制。本发明实施例中基于滑移率的车辆控制方法不仅仅考虑直线行驶状态下的车辆滑移率数据,还对处于转向过程中的目标车辆的滑移数据进行更新以得到更符合实际的滑移率数据,将该滑移率数据提供给车辆ECU进行精准控制。
