【摘要】 分析了汽车道路试验的特点和测试系统结构,总结了测试系统高可靠性、高集成度、同步数据采集、接口CAN化的发展趋势。结合汽车动力学控制系统产业化开发需求,详细阐述了3项汽车道路试验测试技术和方法:汽车位置姿态测量技术、车轮力测量技术和转向输入控制技术。今后汽车道路试验测试技术发展方向是基于GPS的汽车位置姿态测量、基于车轮力传感器的车轮力直接测量、GPS与转向机器人技术集成进行转向精确输入和路径跟随等规则化道路试验。更多还原

【Abstract】 The paper firstly analyzed the characteristic of vehicle road way test and the structure of the test system,and then brought up the development tendency of high reliability,high integration,synchronizing data acquisition,CAN communication interface,and so on.Thirdly,three key technologies were reviewed concretely in light of the industrialization requirement of vehicle dynamic stability control system,i.e.DSC,which include measurement method of the path and attitude of vehicle,the wheel force measurement technology and the steering input control method.The main stream of measurement technology for vehicle road way test in future may be the GPS only based measurement method of the path and attitude of vehicle,wheel force transducer based wheel force measurement method,the integration measurement of GPS devices and steer robot for the precisely steer control and path following road way tests.更多还原
