摘要
A road surface condition detection system capable of quickly and accurately detecting road surface conditions during vehicle running, an active suspension system and an anti-lock brake system using the road surface condition detection system, and a sensor unit for the road surface condition detection system are provided. A sensor unit, provided on a rotor of a rotation mechanism section of a wheel, has an acceleration sensor for detecting an acceleration occurring in the rotational direction of the wheel as the wheel rotates. A signal of the detected acceleration is received by a monitor device, the received signal is compared to a variation pattern of an acceleration signal for each road surface condition, the pattern being previously stored in a storage section to identify a road surface condition, and information of the identified condition is output. Drive control of the active suspension system and the anti-lock brake system is made based on the information of the road surface conditions.
