车辆纵向速度估算算法发展现状综述

车辆的纵向车速是车辆主动安全系统的重要参考信息,在制动防抱死(ABS)和驱动防滑系统(ASR)中,纵向车速是计算纵向滑移率、保持车辆行驶稳定性的重要参数。文章对现存的车辆纵向速度算法进行了分类综述,将其分为基于基本信息的直接计算方法和基于模型信息的间接计算方法两大类,对各种方法的优缺点进行了讨论,并对其发展趋势进行了展望。

The Statement of the Development Situation of the Longitudinal Velocity Estimation Method of the Vehicle

The longitudinal velocity is the important reference to the active safety system of the vehicle, and also the important reference to the longitudinal skid in ABS and ASR. So, the existent longitudinal velocity estimation method of the vehicle is summarized systematically, and is classified into the direct method based on the basic information and the indirect method based on the model information. Then the advantage and disadvantage of the two methods is discussed, and the development trend is prospected.
