摘要
在中国大学生无人驾驶方程式大赛(Formula Student Autonomous China,简称FSAC)上,无人车的线控底盘是将无人算法和车辆运动连接起来的桥梁。线控底盘分为线控制动系统、线控转向系统、传动机构以及ECU控制。无人算法将信息处理算出车辆转角和速度后发送给ECU,ECU再控制转向电机和制动电机以及驱动电机。在满足FSAC赛事规则前提下的整车线控底盘的机械设计以及ECU控制系统的搭建将被介绍。
In Formula Student Autonomous China(FSAC), driverless cars′ drive-by-wire chassis is the bridge connecting Autonomous algorithms and vehicle movements. The drive-by-wire chassis is divided into drive-by-wire steering system, drive-by-wire steering system, transmission mechanism and ECU control. The unmanned algorithm calculates the vehicle’s turning angle and speed through information processing and sends it to the ECU, which then controls the steering motor, braking motor and drive motor. The mechanical design of the vehicle drive-by-wire chassis and the construction of the ECU control system was introduced under the premise of meeting the rules of FSAC.
