With the aim of improving vehicle stability through the introduction of active steering control, the authors undertook the development of a steer-by-wire system which is more effective than the direct yaw-moment control (DYC) while avoiding interference with driver steering. The vehicle stability control begins only after a change in vehicle behavior has been detected, and therefore in the case of full braking test on a /spl mu/-split road and in other situations requiring high responsiveness, the vehicle stabilizing effect is lowered due to time lag until the control starts, and a residual yaw angle is created after the stopping of the vehicle. In order to resolve these problems, a new type of control was developed whereby the driver's steering intent is detected based on the DYC behavior and front-wheel angle deviation between front-wheel rotational speeds. It was verified by on-vehicle testing that the addition control resulted in greater vehicle stability.
Electronic braking systems for air-brake vehicles have been required by the Federal Motor Vehicle Safety Standard 121 since 1975. The need for the standard and the difficulty in documenting its benefits are discussed....
