ROAD SURFACE CONDITION DETECTING SYSTEM, ACTIVE SUSPENSION SYSTEM, ANTI-LOCK BRAKING SYSTEM AND SENSOR UNIT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a road surface condition detecting system capable of detecting promptly and accurately the road surface when a vehicle is running, an active suspension system and an anti-lock braking system therewith, and a sensor unit thereof. SOLUTION: A sensor unit 100 equipped with an acceleration sensor 100 for detecting the acceleration generated in the rotational direction by rotation of a wheel is provided at a rotor of the wheel rotating mechanical section. A detected acceleration signal is received by a monitor system 200, and information of the road surface condition specified in comparison with a variation pattern of the acceleration signal per road surface previously stored in a storage section 250 are outputted. Based on this road surface condition, drive control by the active suspension system and the anti-lock braking system is carried out. COPYRIGHT: (C)2005,JPO&NCIPI
