<p><P>PROBLEM TO BE SOLVED: To provide a vehicle physical quantity estimating device by which a slip angle can be estimated with a high accuracy. <P>SOLUTION: The vehicle physical quantity estimating device 1 includes an ECU 5 for estimating a vehicle physical quantity and an on-vehicle camera 4 for detecting the yaw angleθof a vehicle X. The vehicle physical quantity estimating device 1 calculates an offset errorαbased on an estimated yaw angleθ^ estimated by a vehicle physical quantity observer 5a of the ECU 5 and the yaw angleθdetected by the on-vehicle camera 4. An estimated slip angleβ^ estimated by the vehicle physical quantity observer 5a is corrected with the offset errorα. Namely, the estimated slip angleβ^ is corrected based on the detected yaw angleθand the estimated yaw angleθ^. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
