Patent attributes
A preview road surface detection device of a vehicle of the present invention includes: a distance sensor that is disposed in a vehicle member and detects a distance to a measurement point on a road surface nearer to a front part of the vehicle, corresponding to at least a central portion of a contact patch to the road surface of a wheel of the vehicle; and a distance calculator that calculates a road surface distance from the vehicle member to the measurement point, based on a value detected by the distance sensor. A displacement of the road surface nearer to the front part of the vehicle is detected as a road surface condition. The displacement of the road surface is calculated from the road surface distance and a vehicle height of the vehicle member when the distance sensor detects the distance.
