Abstract

The invention relates to a method for forwarding information by means of a transmitting and receiving device in a first vehicle, having the following steps of: determining a stop state of the first vehicle, determining a position of the first vehicle, receiving information from a first transmitter in a vehicle and/or an infrastructure unit, forwarding the information from the first transmitter to a receiver in a second vehicle by means of the transmitting and receiving device if the position of the first vehicle is within a predefined area. The invention also relates to a device for carrying out the method.

Claims

1. A method for forwarding information by means of a transmission and reception device that is located in a first vehicle, said method comprising:

determining whether the first vehicle is in a stopped state,

determining a position for the first vehicle when the first vehicle is determined to be in the stopped state,

receiving information at the transmission and reception device located in the first vehicle, said received information transmitted by a first transmitter of a vehicle and/or an infrastructure unit, and

forwarding the received information to a receiver located in a second vehicle by means of the transmission and reception device located in the first vehicle, when the first vehicle is determined to be in the stopped state and the position of the first vehicle is determined to be within a prescribed region.

2. The method as claimed in claim 1, wherein the method includes determining the prescribed region from (i) a distance of the first vehicle from a first road, and (ii) a distance of the first vehicle from a second road, the second road leading to the first road, wherein said distances are determined using the position determined for the first vehicle.

3. The method as claimed in claim 1, wherein the method includes determining the prescribed region from the position of the transmission and reception device located in the first vehicle (i) in relation to the first transmitter of the vehicle and/or the infrastructure unit and (ii) in relation to a second transmitter located in the second vehicle, wherein the position of the transmission and reception device is determined from the position determined for the first vehicle.

4. The method as claimed in claim 3, wherein the method includes:

transmitting position information, speed information, and direction of movement information of the vehicle and/or infrastructure unit using the first transmitter, and

transmitting position information, speed information, and direction of movement information of the second vehicle using the second transmitter.

5. The method as claimed in claim 1, wherein the prescribed region is determined using a digital map.

6. The method as claimed in claim 1, wherein the step of forwarding the received information to the receiver located in the second vehicle occurs when at least one electrical energy source in the first vehicle is made available.

7. The method as claimed in claim 6, wherein the energy source is comprised of solar cells.

8. The method as claimed in claim 7, wherein the energy source used for forwarding the received information to the receiver located in the second vehicle includes at least one battery when the solar cells are not made available as an energy source.

9. The method as claimed in claim 8, wherein the transmission and reception device located in the first vehicle does not forward the received information when the state of charge of the at least one battery is below a prescribed limit value.

10. An apparatus for carrying out the method as claimed in claim 1.

11. The method as claimed in claim 1, wherein the first vehicle has a highest priority among a plurality of vehicles located in the prescribed region, each of said plurality of vehicles having a respective transmission and reception device, wherein the highest priority is determined by having a shortest distance between a position of the vehicle and a center of a junction of at least two roads within the prescribed region.
