STEP DETECTION DEVICE AND STEP DETECTION METHOD

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...

Zusammenfassung: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.
