Method for operating an access arrangement
First Claim
1. A method for operating an access arrangement for a vehicle, wherein access to the vehicle can be obtained by means of a mobile identification transmitter, comprising the following steps:
- determining an ambient brightness around the vehicle;
checking for the presence of an authorized mobile identification transmitter in a proximity area around the vehicle;
outputting an activation signal for a lighting source of the vehicle if the ambient brightness is below a predetermined brightness value and the presence of an authorized mobile identification transmitter is detected in the proximity area,wherein the ambient brightness is first determined and the presence of the identification transmitter is only checked for if an ambient brightness below the predetermined brightness value is present.

Abstract
In a method for operating an access arrangement (ZA) for a vehicle (FZ), access to the vehicle can be obtained by a mobile identification transmitter (IDG). With this method, first an ambient brightness around the vehicle is determined. Furthermore, the presence of an authorized mobile identification transmitter in an approach region (ANB, ANB2) around the vehicle is examined. Finally, an activation signal (LSS) for an illumination source (BL) of the vehicle is issued when the ambient brightness drops below a predetermined brightness value and the presence of an authorized mobile identification transmitter is detected in the approach zone. In this way, efficient activation of the illumination source can be achieved.
