摘要
针对现有车速计算方法精度不高、波动大的问题,研究基于车速信号的车辆纵向速度卡尔曼滤波估计算法,并实现该算法在整车控制器中的应用。仿真和实车试验表明,该卡尔曼滤波车速算法具有良好的实时性与较高的滤波精度。
Aiming at the problems of low accuracy and large fluctuation of the present calculation methods for vehicle speed,the speed estimation algorithm of vehicle longitudinal speed Kalman filter based on speed signal is studied,and the application of this algorithm to VCU is realized.The simulation and the real vehicle test show that the speed filter algorithm base on Kalman filter has good real-time performance and higher filtering accuracy.
