Abstract
A method for detecting the surface character of objects in road traffic or of persons, especially pedestrians, vehicles, obstacles and the like, in which signals are emitted from a vehicle that are reflected by a person or an object, and in which the reflected signals are received and evaluated in the vehicle, wherein the emitted signals are transmit pulses whose echo pulses are received, and based on the signal characteristics of the echo pulses, the surface character is inferred, and from that, it is inferred whether a person or an object is positioned in front of the vehicle.

1-7. (canceled)
A method for detecting a surface character of an object in road traffic or a person, the method comprising:
- emitting signals from a vehicle that are reflected by a person or an object;
- receiving and evaluating the reflected signals in the vehicle;
- wherein the emitted signals are transmit pulses whose echo pulses are received, and based on the signal characteristics of the echo pulses, the surface character is inferred, and from that, it is inferred whether a person or an object is positioned in front of the vehicle.
A device for determining a surface character of an object in road traffic or a person in front of a vehicle, comprising:
- pulse-echo sensors emitting and receiving signals;
- at least one signal-analysis device for determining and evaluating signal characteristics of echo pulses reflected by the person or the object;
- and
- at least one control device for triggering at least one of an operating-dynamics system, an occupant protective device, and a pedestrian protective device as a function of the signal characteristics.
