车辆质心的运动规律最能体现当前车辆的自身运动状态,而车辆在行驶过程中,质心是时刻变化的,很难对质心位置准确定位。利用Carsim对车辆质心运动进行仿真,以设定道路曲线为基准,让试验车沿指定路线行驶,对仿真结果进行对比分析。试验结果表明:通过识别车轮与质心的相对速度就能辨识出车辆当前的运动状态。 The law of movement of the vehicle’s center of mass can best reflect the current movement state of the vehicle, and the center of mass of the vehicle changes momentarily while driving, and it is difficult to accurately locate the position of the center of mass. Using Carsim to simulate the vehicle’s centroid motion, set the curve of the road as a benchmark, let the test vehicle travel along the designated route, and make a comparative analysis of the simulation results. The experimental results show that the vehicle’s current state of motion can be identified by identifying the relative speed of the wheel and the center of mass.
