摘　　要：针对汽车纵向速度的实时计算问题,在分析汽车纵向运动学及动力学特性的基础上,提出了一种基于混合法和互补滤波器的车速实时计算方法。为了进一步提高车速计算系统在防抱死制动系统(ABS)干扰下的性能,根据互补滤波原理设计了一种扩展计算系统。为验证算法的有效性,搭建仿真平台,进行了相关的仿真实验。仿真结果表明,所提出的算法能够实现对汽车速度的实时计算,且具有较好的抗干扰性。Based on the analysis of vehicle longitudinal kinematics and dynamic characteristics,a real-time calculation method of vehicle longitudinal velocity based on hybrid method and complementary filter is proposed.In order to further improve the performance of the speed calculation system under the interference of anti-lock braking system(ABS),an extended calculation system was designed according to the principle of complementary filtering.In order to verify the effectiveness of the algorithm,a simulation platform was built and relevant simulation experiments were carried out.Simulation results show that the proposed algorithm can realize real-time calculation of vehicle speed and has good anti-interference performance.
