The hardware circuits were designed for main system, power system, signal conditioning, accelerator pedal signal collection, CAN (controller area network) bus collection, and the output system. The TCS had four modules for starting, running, braking, and fault monitoring. TCS control strategies were developed for different operating conditions. The function verification test was compl
