The programming software is open. Students can simulate the working process and various faults of steering by adjusting the program data; 3) Function 3: Wire control remote control technology modification: The wire control chassis is realized through the communication interface, and the vehicle forward, backward, braking, and steering can be remotely controlled; 4) Function 4: In addition to the manual driving of the original vehicle, it is also equipped with automatic driving and remote control driving (remote control driving is optional), which can feedback information such as four-wheel speed, brake pressure, steering wheel angle, etc. The automatic driving system only needs to interact with the CAN0 line of the chassis VCU; 5) Function 5: Vehicle diagnosis and control system, through the communication interface to realize the wire control chassis comprehensive control, can write, merge, and integrate the communication protocol. Test software: 3.1 Wire-controlled chassis test software: 1) The system can display the data information of the wire-controlled chassis in real time. 2) Different steering angles and zero positions can be set. 3) Vehicle speed, acceleration, and gear can be set. 3.2 Autonomous driving software 1) The software is based on the ROS system or Autoware system framework 2) The software meets the function of realizing environmental perception and drawing digital maps 3) The software meets the function of realizing autonomous driving obstacle avoidance Training courses: 1. Understanding of CAN communication module 2. New energy vehicle chassis motion data test experiment 3. Installation and testing of wire-controlled steering 4.
