Research on Vehicle Engine Cooling System Based on Self-adjusting Fuzzy Control Strategy

A simplified mathematical model of the vehicle engine electronic control cooling system is established by using the lumped parameter method, and non-linear control strategy and fuzzy control strategy are introduced to simulate the cooling system. Taking the optimal coolant temperature of the vehicle engine outlet as the research objective, non-linear controller, fuzzy controller and self-adjusting fuzzy controller are designed to control the engine coolant temperature and to study the energy consumption optimization of the cooling system. Experiments show that compared with non-linear control, self-adjusting fuzzy control, and fuzzy control strategy, When the engine is in the maximum heat load and the electronic valve is fully open, the energy consumption of the cooling system can be reduced by 33% by using self-adjusting fuzzy control strategy.
