LANE KEEPING CONTROL SYSTEM

摘要

In the present invention, a road-surface-condition estimating apparatus is formed of a tire-side apparatus (1) and a vehicle-side apparatus (2), so that a road surface condition can be ascertained on the basis of road-surface-condition data sent from the tire-side apparatus (1). This allows for accurately detecting the road surface condition or road surface μ of the road surface on which the vehicle travels and performing more accurate lane keeping control in accordance with the detected result. In particular, the tire-side apparatus (1) can estimate the road surface condition more precisely because the tire-side apparatus (1) estimates the road surface condition by detecting the vibration of the ground contact surface of the tire. In this way, more accurate lane keeping control is possible.
