The Four-wheel drive electric vehicle (EV) is driven by four hub motors. In the hub motor drive system, three hall-effect sensors are usually used to provide absolute rotor position information, correspond to the block commutation algorithm for BLDC motors. However, the waveform of the back electromotive force (EMF) of the hub motor is not trapezoidal, but between sinusoidal and trapezoidal shape...
In this paper, the control system for a four-wheel-driven micro electric vehicle has been designed, which consists of vehicle control unit (VCU), wheel-motor control unit (MCU), battery management system (BMS) and time-triggered CAN (TTCAN) communication network. The VCU, as a key component of the whole system, gives orders to other modules based on the driver manipulation, data from other modules...
