近年来,随着汽车行驶速度的提高及道路行车密度的增大,汽车的主动安全性受到了各大汽车制造厂商的高度重视。汽车主动安全性是根据汽车理论对汽车内部的结构、装置,进行合理、有效地设计,来主动预防事故的发生。丰田汽车公司用在高端车型上的VDIM(Vehicle Dynamics Integrated Management—车辆动态综合管理)系统,就是车辆主动安全性装置 In recent years, with the increase of vehicle traveling speed and the increase of road driving density, the active safety of vehicles has been highly valued by the major automobile manufacturers. Active safety of car is based on the car theory of the car’s internal structure, device, a reasonable and effective design, to take the initiative to prevent accidents. Toyota Motor Corporation used in high-end models VDIM (Vehicle Dynamics Integrated Vehicle-Vehicle Dynamic Management System), is the vehicle active safety device
