Abstract

Methods and an appropriately setup communication unit for positioning in vehicle-to-surroundings communication are described, wherein the method involves a first sensor (S1) of a first communication subscriber using a transmission and reception unit to emit a challenge pulse, to which a transmission and reception unit of a second sensor (S2) of a second communication subscriber responds with a response pulse. The response pulse is received and evaluated by the first sensor (S1) and positioning is performed. In order to achieve reliable cooperative sensor communication, the transmission and reception units of the first and second sensors (S1, S2) use a frequency band (SCH2) which is reserved for vehicle-oriented safety applications.

Dependent claims

A method for positioning in vehicle-to-surroundings communication, the method including:

controlling, by a first sensor of a first communication subscriber, a first transmission and reception unit to emit a challenge pulse including a first code;
receiving, by the first transmission and reception unit, a response pulse from a second transmission and reception unit controlled by a second sensor of a second communication subscriber, the response pulse including a second code and an identification number identifying the second sensor;
and
evaluating, by a computation unit controlled by the first sensor, the response pulse to determine a position of the second sensor relative to a position of the first sensor, the transmission and reception units of the first and second sensors using a frequency band (SCH2) which is reserved for vehicle-oriented safety applications.
