The design and study of the whole vehicle thermal management system and control strategy of electric mine carrier vehicles are carried out to solve the problem of heat dissipation and cab comfort of engineering vehicles under outside high temperature environment.According to the characteristics of thermal management demand of mine transport vehicle,the design scheme and control principle of independent cooling system are proposed for the whole vehicle cab,battery and motor,and the matching of core system components and the construction of simula-tion model are completed.The proportional integral differential(PID)controller and fuzzy PID controller are estab-lished by combining AMESim and MATLAB/Simulink software,and the joint simulation analysis is carried out un-der different external temperatures and vehicle speeds.The simulation results show that the fuzzy PID control re-sponse is sensitive,the overshoot is small,and the cab temperature can be more steadily controlled to the target temperature,meeting the design requirements.This thermal management system design can provide a design idea for intelligent thermal management system of mine engineering vehicles in the future.
