Abstract

To investigate the dynamic characteristics of an automotive and develop a control method for its safe braking, a dynamic model of the car with active suspension devices during its braking was established. The dynamic model was with 4 degrees of freedom, that is, two degrees of freedom with the car body and others with forefront wheels and rear wheels. For the purpose of reliable use of the control method in most cases, a wavy road was included in the problem. Considering random road surface, braking deceleration and traveling speed of the car when braking, a fuzzy control method was used. Based on a real car made in China, computer simulation was adopted to investigate the dynamic characteristics of the car and the fuzzy control method. The results show that under the condition of an elaborately developed fuzzy control method used in the 4 active suspension devices, the displacement of the mass center and the turnover angle of the car body are greatly reduced and about only one half of their original values are remained.
