1. A method for ascertaining a position of an object in surroundings of a vehicle, the method comprising:
- inputting a light signal from an optical sensor;
determining a light distribution from the light signal;
comparing the determined light distribution, affected by a reflection of light emitted by a headlight of the vehicle, to a stored expected light distribution of the headlight; and
determining a position of the object relative to the vehicle based on a result of the comparison.

Abstract
A method for ascertaining a position of an object in surroundings of a vehicle. The method includes a step of input of a light signal from an optical sensor, the light signal representing a brightness, a degree of reflection of light emitted by a headlight of the vehicle from an object, and/or a sharpness of a boundary line of the object illuminated by light from a headlight. Furthermore, the method includes determining a distance of the object from the vehicle by using the light signal to determine the position of the object in the surroundings of the vehicle.

11. A device for ascertaining a position of an object in surroundings of a vehicle, comprising:
-
processing circuitry; and an interface by which the processing circuitry is configured to obtain a light signal from an optical sensor; wherein the processing circuitry is configured to; determine a light distribution from the light signal; compare the determined light distribution, affected by a reflection of light emitted by a headlight of the vehicle, to a stored expected light distribution of the headlight; and determine a position of the object relative to the vehicle based on a result of the comparison.
