1. A device for outputting a signal when there is a hazardous underlying surface under a vehicle, 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;
(i) when the underlying surface has been determined to be hazardous on the basis of the at least one parameter; and
(ii) 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; (i) when the underlying surface has been ascertained to be hazardous; and (ii) the vehicle is stationary or is to be brought to a stop. - View Dependent Claims (10, 11, 12, 13, 14, 16, 17, 18)
