《Vehicle System Dynamics: International Journal of Vehicle Mechanics and Mobility》2012,50(2-3):77-117
The development of automotive systems shows an increasing number of sensors, actuators and microelectronic controllers, partially for active driver assistance. However, electronic and electrical components have quite different failure behavior and in general lower reliability than mechanical components. On the other side microcomputers can also be used for fault detection and diagnosis. The contribution therefore shows how model-based fault detection and diagnosis methods together with few available measurements can be applied for automobiles. After an introduction, a short summary is given for fault detection and diagnosis methods, especially for model-based methods. Then some research results are shown, like the fault detection and diagnosis of an electromechanical throttle actuator, a suspension system and the lateral behavior of a passenger car. Finally, methods for fault-tolerant sensors and actuators are discussed which are required for drive-by-wire systems. 相似文献
