RUNNING STATE ESTIMATION DEVICE, AUTOMOBILE AND RUNNING STATE ESTIMATION METHOD

PROBLEM TO BE SOLVED: To estimate a sideslip angle easily and accurately by a simple structure. SOLUTION: A yaw rate and a lateral wheel speed difference are normally in a one-to-one linear relationship, but the relationship varies when a sideslip angle develops. The sideslip angle β of a vehicle bo...

Zusammenfassung:	PROBLEM TO BE SOLVED: To estimate a sideslip angle easily and accurately by a simple structure. SOLUTION: A yaw rate and a lateral wheel speed difference are normally in a one-to-one linear relationship, but the relationship varies when a sideslip angle develops. The sideslip angle β of a vehicle body is then estimated in accordance with the yaw rate γ of the vehicle body and the lateral wheel speed difference (VRW-VLW). COPYRIGHT: (C)2008,JPO&INPIT
