Abstract

A method and apparatus are provided for controlling a vehicle travelling in a platoon. A first set of information is received at a first vehicle in a platoon, the first set of information relating to at least one other vehicle in the platoon. One of a plurality of control algorithms is selected in dependence on the first set of information, wherein each of the plurality of control algorithms correspond to a respective platoon communication topology. The first vehicle is controlled in response to the first set of information and the selected one of the control algorithms.

Claims

1. A method for controlling a vehicle travelling in a platoon comprising:

receiving a first set of information at a first vehicle in a platoon, the first set of information relating to at least one other vehicle in the platoon;

selecting one of a plurality of control algorithms in dependence on the first set of information, wherein each of the plurality of control algorithms correspond to a respective platoon communication topology; and

controlling the first vehicle in response to the first set of information and the selected one of the control algorithms.

2. The method of claim 1, wherein the first set of information comprises at least one of radar information and one or more vehicle to vehicle messages.

3. The method of claim 1 further comprising:

storing the first set of information in a memory;

4. The method of claim 1 further comprising:

receiving a second set of information at the first vehicle;

selecting a further one of the plurality of control algorithms in dependence on the second set of information; and

controlling the first vehicle in response to the second set of information and the selected further one of the control algorithms.

5. The method of claim 4 further comprising:

determining that no vehicle to vehicle messages are received as part of the second set of information; and

selecting a prediction control algorithm from the plurality of control algorithms, the prediction control algorithm configured to predict further information for the second set of information based on the stored first set of information.

6. The method of claim 4, wherein the predicted further information corresponds to information carried in vehicle to vehicle messages.

7. The method of any preceding claim wherein the memory is further configured to store control boundary information.

8. The method of claim 7, wherein the step of controlling the first vehicle further comprises controlling the first vehicle further in response to the control boundary information.

9. The method of claim 4 further comprising:

determining that no vehicle to vehicle messages are received as part of the second set of information; and

requesting information from at least one other vehicle in the platoon.

10. An apparatus for controlling a first vehicle in a platoon, the apparatus comprising:

at least one receiver configured to receive a first set of information relating to at least one other vehicle in the platoon; and

a controller configured to;

select one of a plurality of control algorithms in dependence on the first set of information, wherein each of the plurality of control algorithms correspond to a respective platoon communication topology; and

provide control signals configured to control the first vehicle in response to the first set of information and selected control algorithm.

11. The apparatus of claim 10 further comprising:

a memory configured to store the first set of information.

12. The apparatus of claim 10, wherein when the receiver receives a second set of information, the controller is further configured to:

select a further one of the plurality of control algorithms in dependence on the second set of information; and

provide control signals configured to control the first vehicle in response to the second set of information and the selected further one of the control algorithms.

13. The apparatus of claim 12, wherein the controller is further configured to determine that no vehicle to vehicle messages are received as part of the second set of information and select a prediction control algorithm from the plurality of control algorithms, the prediction control algorithm configured to predict further information for the second set of information based on the stored first set of information.

14. The apparatus of claim 10 further comprising:

a transmitter configured to transmit information associated with the first vehicle to at least on other vehicle in the platoon.

15. The apparatus of claim 10 further comprising:

a vehicle controller configured to receive the control signals and control the behaviour of the first vehicle in response thereto.
