 ABSTRACT Because of the significant advantages in energy conservation and environmental protection, electric vehicles are regarded as a hot research object in the world. As a new electric vehicle drive wheel driven electric vehicle, with body inner space utilization rate is high, to import by wire steering technology to enhance steering sensitivity, easy through the motor control technology realization of ABS, TCS, and ESP performance, easy to achieve the braking energy feedback to save energy and other significant advantages, become the focus of development of electric motor car in the future.
    I am reading a large number of domestic and international electric vehicle related books and papers on the control of independent wheel drive wheel drive electric vehicle as the research object, the wheel driving system of motor control technology research as the research objective, through the analysis of motor and control technology of electric vehicles, the permanent magnet synchronous the motor (PMSM) vector control, wheel drive controller of the system from hardware and software (based on software) was studied. The hardware design includes the general scheme of the hardware design of STM32 control system and gives the main circuit principle diagram based on the main control system initialization, PWM timing interrupt service program, control instruction the receiving state and data transmission, fault protection interrupt service program in the part of software design analysis. At last, the fuzzy control of wheel edge drive system is studied, and the future research direction of wheel edge drive system is analyzed.
