Stability Control and Simulation Analysis of Automobile Hydraulic System ESP

Abstract

Abstract. Role car ESP hydraulic system is applied to the appropriate wheel hydraulic braking force, the implementation of active intervention of the vehicle, so that the car during braking, good stability, and therefore directly affect the effective control of the ESP braking car security. Thesis for the dynamic characteristics of cars ESP hydraulic system research, based on AMESim software to establish the ESP hydraulic system model is proposed fuzzy PID as the ESP control strategies, the use of AMESim and Simulink co-simulation results show that the method can effectively improve the car's braking stability, there are certain practical significance.
