摘要：
The integrated system of electromagnetic brake and friction brake of car can improve braking performance effectively, reasonable control strategy is the key to realizing the integrated system. Because of the non-linearity and time variation of vehicle brake system, based on the analysis of 1/4 vehicle model, the integrated system model and the fuzzy control theory, the control strategy using fuzzy control of the amount of current flowing in the electromagnetic brake coil is proposed, in which the vehicle slip rate is used as input, the current of the electromagnetic brake is used as output, thus the fuzzy controller of the system is designed. To prove its validity and feasibility, a vehicle equipped with the integrated system of electromagnetic brake and frictional brake is taken as example. Matlab/Simulink software is used to carried out simulation analysis of the system. Comparison is made between the vehicles with and without the fuzzy controller. The simulation result shows that the integrated system using fuzzy strategy can effectively reduce braking time and shorten braking distance, so the proposed control strategy is feasible. © 2010 Journal of Mechanical Engineering.
