Abstract:
A step detection device, including a distance measurement unit which detects the height of the road surface around a vehicle, approximates with a curve, the gradient of the road surface in a travelable region in the vehicle width direction, based on the height of the road surface, and detects a step on the road surface, based on the agreement degree of the height of a measurement point relative to the curve and the agreement degree of the height of a measurement point relative to a curve with which the gradient of the road surface in an extended region defined by extending the travelable region in the vehicle width direction is approximated.

Claim (Index 6):
A step detection device comprising:\n a distance sensor which detects a height of a road surface around a vehicle; a travelable region circuit which estimates a travelable region in a traveling direction of the vehicle; a road surface gradient circuit which approximates with a curve, a gradient of the road surface in the travelable region in a vehicle width direction, based on the height of the road surface detected by the distance sensor; and a step detection circuit which detects a step on the road surface, based on an agreement degree of a height of a measurement point set in the travelable region relative to the curve, and an agreement degree of a height of a measurement point set in an extended region, defined by extending the travelable region in the vehicle width direction, relative to a curve with which a gradient of the road surface in the extended region is approximated.
