Communication system in a motor vehicle, and method for setting up a wireless ad-hoc radio network
First Claim
1. A method for setting up a wireless ad-hoc radio network including a plurality of traveling motor vehicles, the method comprising:
- determining an orientation of a first vehicle with respect to a reference direction and initializing the setting up of the ad-hoc network;
wirelessly communicating the orientation of the first motor vehicle to a least a second motor vehicle;
determining in the second motor vehicle an orientation of the second motor vehicle with respect to the reference direction;
determining in the second motor vehicle a relative orientation of the second motor vehicle with respect to the first motor vehicle;
evaluating in the second motor vehicle the relative orientation of the first motor vehicle with respect to the second motor vehicle; and
deciding whether the second motor vehicle becomes a participant in the ad-hoc radio network based on the relative orientation of the first motor vehicle with respect to the second motor vehicle.

Abstract
Presented is a communication system in a motor vehicle which is designed to participate in a chain-like ad-hoc radio network comprising a number of traveling motor vehicles. The system includes a control unit, a transmission/reception unit in communication with the control unit, and an orientation unit configured to determine an orientation of the motor vehicle relative to a reference direction, the orientation unit being in communication with the control unit. The control unit is configured to determine the orientation of the motor vehicle with respect to an orientation of at least one other motor vehicle which is received by the transmission/reception unit.

7. A method of adding an (n+1)th traveling motor vehicle to an ad-hoc radio network including n traveling motor vehicles, the method comprising the step of:
-
receiving, by a transmission/reception unit of the (n+1)th motor vehicle, an inquiry from the nth motor vehicle in the ad-hoc radio network; determining in the (n+1)th motor vehicle a first relative orientation of the (n+1)th motor vehicle with respect to the reference direction; determining in the (n+1)th motor vehicle a second relative orientation of the (n+1)th motor vehicle with respect to the nth motor vehicle; determining in the (n+1)th motor vehicle a third relative orientation of the (n+1)th motor vehicle with respect to the first motor vehicle in the chain of motor vehicles in the ad-hoc network; determining whether the (n+1)th motor vehicle becomes a participant in the ad-hoc radio network based on the second and third relative orientations.

8. A method for setting up a wireless chain-type ad-hoc radio network between motor vehicles with communication systems for communication from motor vehicle to motor vehicle, comprising:
-
determining an orientation of a first motor vehicle with respect to a reference direction initializing the setting-up of the ad-hoc radio network; communicating the orientation of the first motor vehicle wirelessly by a respective communication system for the communication from motor vehicle to motor vehicle of the first motor vehicle to a respective communication system for the communication from motor vehicle to motor vehicle of a second motor vehicle; determining, in the second motor vehicle, an orientation of the second motor vehicle with respect to the reference direction; determining in the second motor vehicle a relative orientation of the second motor vehicle with respect to the first motor vehicle using the orientation with respect to the reference direction of the first and the second motor vehicle; evaluating, in the second motor vehicle, the relative orientation of the first motor vehicle with respect to the second motor vehicle is carried out and on the basis of a result of the evaluation, a decision is made whether the second motor vehicle becomes a participant in the ad-hoc radio network by the communication system for the communication from motor vehicle to motor vehicle; wirelessly communicating by the second motor vehicle by its respective communication system for the communication from motor vehicle to motor vehicle to a communication system for the communication from motor vehicle to motor vehicle of at least one third motor vehicle, the orientation with respect to the reference direction of the first motor vehicle and of the second motor vehicle; determining in the third motor vehicle an orientation of the third motor vehicle with respect to the reference direction; determining in the third motor vehicle with the use of the orientation with respect to the reference direction of the first to the third vehicle a relative orientation of the third motor vehicle with respect to the first motor vehicle and the second motor vehicle; evaluating in the third motor vehicle the relative orientation of the first motor vehicle with respect to the third one and of the second motor vehicle with respect to the third one based on a result of the evaluation; and deciding whether the third motor vehicle becomes a participant in the ad-hoc radio network by the communication system for the communication from motor vehicle to motor vehicle. - View Dependent Claims (9, 10, 11, 12)
