Design and Controlling Study on Electro-Hydraulic Mix-Drive Cooling System in Vehicle

This thesis analysis the work course of the system, the match of major part, a fuzzy method for controlling the engine coolant temperature is proposed. The fuzzy rule base is correspondingly established based on the experimental data. The control query table is created through computing and analyzing via the fuzzy logic tools in MATLAB. The test indicates that only a little improvement of the current engine cooling system can better solve the problem that it is difficult to accurately control the engine coolant temperature.
