First Claim
Patent Images
1. A device for outputting a signal when there is a hazardous underlying surface under a vehicle, wherein the device comprising:
- an optical surface sensor configured to determine at least one parameter of the underlying surface;
a stoppage ascertainment unit configured to determine whether the vehicle is stationary or is to be brought to a stop; and
an output unit configured to output a signal when the underlying surface has been determined to be hazardous on the basis of the at least one parameter and whether the vehicle is stationary or is to be brought to a stop.

Abstract
A method and a device for outputting a signal when there is a hazardous surface under a vehicle includes providing an optical surface sensor for determining one or more parameters of the underlying surface, a stationary-state-determining device for determining whether the vehicle is stationary or is to be brought to a standstill, and an output device that outputs a signal if the underlying surface has been determined to be hazardous on the basis of the parameter(s), and the vehicle is stationary or is to be brought to a standstill.

9. A method for outputting a signal when there is a hazardous underlying surface under a vehicle, the method comprising:
-
emitting at least one light beam onto the underlying surface; detecting light reflected on the underlying surface; ascertaining on the basis of the detected reflected light whether the underlying surface is hazardous; ascertaining whether the vehicle is stationary or is to be brought to a stop; and outputting a signal when the underlying surface has been ascertained to be hazardous and the vehicle is stationary or is to be brought to a stop. - View Dependent Claims (10, 11, 12, 13, 14, 16)
