Whole vehicle thermal management strategy optimization method and system based on one-dimensional and three-dimensional joint simulation

The invention discloses a vehicle thermal management strategy optimization method and system based on one-dimensional and three-dimensional joint simulation, and the method comprises the steps: taking cooling water flow and air flow as decision variables, and randomly generating a primary control strategy; performing one-dimensional and three-dimensional joint simulation of the cooling system based on the primary control strategy; and taking the maximum temperature of the fire face of the cylinder cover obtained through simulation and the average heat exchange amount of the outer wall face of the cylinder sleeve as to-be-optimized targets, and updating a control strategy until an iteration condition is met, so as to obtain an optimal control strategy. A one-dimensional and three-dimensional joint simulation technology is coupled in a multi-objective optimization algorithm of an electronic water pump and electronic fan control strategy, and the reliability of the optimization process is improved. 本发明公开一种基于一维三维
