Abstract
Nowadays, the study on advancing safety factor of automobile, especially in the bus is concerned by many scientists. One of the factors for optimizing safety coefficient that deserve to be mentioned is related to the research, design and perfect construction of suspension system, steering system and brake system to ensure smooth, high safety in motion. This paper presents the results of applied research on the theoretical basis of the linear quadratic regulator (LQR) to control the semi-active suspension system for bus to enhance the smooth movement on rough road. At the same time, the authors set up mathematical models and surveys in the time domain of semi-active suspension system in different working modes, through which the results of a bus ride comfort in using semi-active suspension system will be optimized in comparison with the passive suspension.
