| Abstract: | For the rules of Formula Student China competition,this system is designed to introduce theμC/OS-III embedded realtime operating system,use the wireless data transmission module and develop PC monitoring software independently.A complete vehicle control system based on wireless data acquisition technology for electric vehicles was designed and implemented.The system design consists of three parts:vehicle controller unit,instrument controller unit and wireless data acquisition system.The vehicle controller unit is responsible for collecting the accelerator pedal and brake pedal sensor signals,and send the required torque and brake signals from the look-up table to the motor controller so that the motor controller unit drives the motor.The instrument controller unit obtains the data of the BMS and MCU from the CAN bus and displays on the screen.The signals of the sensors are collected,and these obtained data is wirelessly transmitted to the computer for monitoring software.The system design develops the monitoring software of the wireless data acquisition system,which can monitor the running status of the vehicle and diagnose the fault condition of the vehicle. |
