Abstract: Light electric trucks driven by wheel hub have broad application prospects in intercity logistics transportation, but wheel hub motors still face the problems of heat dissipation and low control accuracy in automotive applications. Firstly, by comparing the advantages and disadvantages of different driving forms of pure electric vehicles, this paper points out the limitations of the current technological development of pure electric vehicles. Secondly, by introducing the industry-related scholars in the wheel hub motor cooling and drive control research work, and the characteristics and shortcomings of the research in this field are summarized. Finally, the design of wheel hub motor drive control system for light electric trucks is proposed, and a new cooling system is designed based on Arduino open source electronic platform to solve the heat dissipation problem of hub motor. The drive control system adopts self-developed control algorithms, combined with proportion-integraldifferential (PID) and linear quadratic regulator (LQR) dual algorithm closed-loop feedback control to achieve precise differential control; The cooling system adopts a double-layer cooling scheme combining liquid cooling and air cooling, which can achieve dynamic cooling power adjustment and improve the heat dissipation efficiency of the cooling system.
