Design of the Control System for a Four-wheel Driven Micro Electric Vehicle

Abstract—In this paper, the control system for a four-wheeldriven
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 via
TTCAN and information collected by other vehicle sensors. The
battery management system (BMS) is responsible for the battery
maintenance and state estimation. The four motor control units
(MCU) control the wheel motor locally according to the
command from VCU. The TTCAN network is based on the
conventional CAN and realized by software.
