Sensor device, for identifying condition of road surface from inside motor vehicle, has radiation receiver to measure radiation emitted by area of road surface

摘要

A radiation receiver measures radiation emitted from an area of road surface. Devices process measured radiation values into a quantity that distinguishes the road surface and is suitable for triggering a control unit for driving conditions. Independent claims are also included for: (A) A system for triggering a driving-condition control unit in a motor vehicle; and (B) A method for identifying the condition of a road surface from inside a vehicle.
