国Ⅴ排放标准中对汽车排放耐久性能提出了更高的要求,结合国内车辆和实际使用情况,开发了能够在底盘测功机上使用的自动驾驶仪。该自动驾驶仪基于EtherCAT实时以太网,实现了对油门、离合器、换挡、刹车等多工位协同的多轴运动控制。试验结果表明,该系统具有良好的实用性和可靠性。 The national V emission standard puts forward higher requirements on the durability of vehicle emissions. In combination with domestic vehicles and actual usage, an autopilot that can be used on a chassis dynamometer has been developed. The autopilot is based on EtherCAT real-time Ethernet and enables coordinated multi-axis motion control of the throttle, clutch, shift, brake and more. The experimental results show that the system has good practicability and reliability.
