Abstract

A trailer parameter identification system (1) for identifying at least one geometrical parameter relating to a trailer (5) comprises at least one sensor (9, 10, 11, 7A, 7B) and a processor (33A, 33B). The at least one sensor (9, 10, 11, 7A, 7B) is configured to acquire data. The processor (33A, 33B) is configured to process said data to generate a value representative of a geometrical parameter of the trailer (5).

Claims

1. A system for identifying at least one geometrical parameter of a trailer, the system being adapted to be installed on-board a vehicle, the system comprising:

a processor; and

at least one sensor for acquiring data relating to the trailer as the vehicle drives past the trailer and arranged to send the data to the processor,

wherein the processor is configured to process the data to generate a value representative of the at least one geometrical parameter of the trailer, the at least one geometrical parameter comprising a hitch length of the trailer between the tow coupler and the wheel axle;

wherein the processor is configured to generate the at least one geometrical parameter with reference to a distance traveled by the vehicle as it travels past the trailer.

2. The system of claim 1, wherein the at least one geometrical parameter comprises one or more of the following:

a tow bar position;

a maximum length of the trailer;

a rear overhang of the trailer;

trailer shape; and

number of wheels.

3. The system of claim 1, wherein the at least one geometrical parameter comprises a number of axles of the trailer.

4. The system of claim 1, wherein the processor is configured to process the data to generate a descriptive result related to the trailer.

5. The system of claim 4, wherein the descriptive result is associated with a shape of the trailer.

6. The system of claim 4, wherein the descriptive result is associated with a type, class or category of the trailer.

7. The system of claim 1, wherein the at least one sensor is:

a camera, a radar, a vehicle parking sensor, an ultrasonic transceiver, or a laser scanner.

8. A vehicle comprising the system of claim 1.

9. The vehicle of claim 8, further comprising a GPS (global positioning system) configured to cooperate with the system in order to associate at least one GPS coordinate to the trailer.

10. The system of claim 1, wherein the at least one sensor is configured to acquire data from one or both sides of the vehicle.

11. A method of identifying at least one geometrical parameter of a trailer, the method comprising:

acquiring data relating to the trailer via at least one sensor incorporated into a vehicle, the data being acquired as the vehicle drives past the trailer; and

processing the data to generate a value representative of a geometrical parameter of the trailer comprising a hitch length of the trailer between the tow coupler and the wheel axle, wherein the at least one geometrical parameter is generated with reference to a distance travelled by the vehicle as it travels past the trailer.

12. A computer program product for configuring or reconfiguring a vehicle system having at least one sensor and a processor, the computer program product comprising a non-transitory computer readable storage medium including computer readable program code, wherein the computer readable program code, when executed on the vehicle system, configures or reconfigures the vehicle system for performing the method of claim 11.

13. The method of claim 11, wherein the at least one geometrical parameter comprises one or more of the following:

a tow bar position;

a maximum length of the trailer;

a hitch length of the trailer;

a rear overhang of the trailer;

trailer shape;

number of wheels;

trailer loading; and

trailer tire pressures.

14. A trailer parameter identification apparatus configured to carry out the method of identifying at least one geometrical parameter of a trailer according to claim 11.
