A method is provided for operating a motor vehicle () having a headlight () with a projection module (). The projection module () is moved into a projection position by a motor () to regulate a beam width of the headlight (). The motor () is controlled to move the projection module () into the projection position and to reach a motor setpoint value. The motor setpoint value is stored in a non-volatile memory () of the headlight () and, when a voltage supply to the headlight () is activated following deactivation of the voltage supply, the projection module () is moved, starting from the stored motor setpoint value, into a leaving-home position so as to illuminate an environment adjacent to the motor vehicle (). A headlight () and a motor vehicle () also are provided.

Method for operating a motor vehicle with a headlight for the fast and safe setting of a leaving-home position, headlight, and motor vehicle

A high-definition vehicular headlamp has a light module configured to produce a matrix of light-emitting points each of which has a coordinate pair. The headlamp generates a light image in front of the vehicle, and the light image is divided into a matrix of pixels that correspond respectively to the light-emitting points of the light module. A specified partial image content is generated in a partial region of the light image. The partial image content acts upon a set of coordinate pairs of light-emitting points, including coordinate pairs having defective light-emitting points that could cause pixel errors. A displacement vector is formed by comparing coordinate pairs of defective light-emitting points with the set of coordinate pairs of the light-emitting points on which the partial image content acts, and the partial image content is reproduced in the partial region of the light image that has been displaced by the displacement vector.
