Abstract

A vehicular camera includes a housing, a lens, an image sensor positioned for receiving images from the lens, a processor, and a memory. The memory contains a plurality of overlays. The processor is programmed to (a) receive first input data from a vehicle in which the camera is to be mounted, wherein the first input data correspond to the configuration of the vehicle, and (b) select a particular overlay to display based at least in part on the input received.

Claims

1. A driver assistance system of a vehicle, said driver assistance system comprising:

a camera, wherein said camera comprises a lens and an image sensor for capturing image data;

a processor;

a memory, wherein the memory stores a plurality of overlays;

wherein the processor is operable to receive a first input pertaining to a vehicle that is to be equipped with the driver assistance system, wherein the first input corresponds to a vehicle configuration of the vehicle that is to be equipped with the driver assistance system; and

wherein the processor is operable to select a particular overlay from the stored plurality of overlays to display based at least in part on the first input.

2. A driver assistance system as claimed in claim 1, wherein, with a vehicle equipped with the driver assistance system, the processor is further operable to receive a second input corresponding to a steering wheel angle of the equipped vehicle, and wherein the plurality of overlays stored in the memory includes overlays relating to predicted vehicle trajectory, and wherein the processor is operable to select a particular overlay to display based at least in part on the second input.

3. A driver assistance system as claimed in claim 2, wherein, if the vehicle configuration is available with different steering gear ratios, a value is provided in the second input when the steering wheel of the equipped vehicle is at full lock, and wherein the processor is further operable to determine information regarding the steering gear ratio of the equipped vehicle based on the second input.

4. A driver assistance system as claimed in claim 1, wherein the plurality of overlays stored in the memory includes at least one first overlay corresponding to a first vehicle configuration and at least one second overlay corresponding to a second vehicle configuration.

5. A driver assistance system as claimed in claim 1, wherein the plurality of overlays stored in the memory includes at least one first overlay corresponding to a first vehicle configuration and at least one common overlay corresponding to both the first vehicle configuration and a second vehicle configuration.

6. A driver assistance system as claimed in claim 1, wherein the processor determines which overlay to display by accessing a look up table based at least in part on the first input.

10. A driver assistance system as claimed in claim 1, wherein the plurality of overlays stored in the memory includes overlays relating to predicted vehicle trajectories, and wherein, with a vehicle equipped with the driver assistance system, the processor is operable to select a particular overlay to display based at least in part on a steering wheel angle of the equipped vehicle.

7-9. -9. (canceled)

11. A driver assistance system, said driver assistance system comprising:

a camera, wherein said camera comprises a lens and an image sensor for capturing image data;

a processor;

a display;

a memory, wherein the memory stores a plurality of overlays;

wherein the processor is operable to select a particular overlay from the stored plurality of overlays based at least in part on a configuration of a vehicle to be equipped with the driver assistance system, and wherein the driver assistance system is operable to display the selected particular overlay on the display; and

wherein the plurality of overlays stored in the memory includes at least one first overlay corresponding to a first vehicle configuration and at least one common overlay corresponding to both the first vehicle configuration and to a second vehicle configuration.

12. A driver assistance system as claimed in claim 11, wherein the configuration of the vehicle is provided as an input to the driver assistance system.

13. A driver assistance system as claimed in claim 11, wherein the processor determines which overlay to display by accessing a look up table.

14. A driver assistance system as claimed in claim 11, wherein the plurality of overlays stored in the memory includes overlays relating to predicted vehicle trajectories, and wherein, with a vehicle equipped with the driver assistance system, the processor is operable to select a particular overlay to display based at least in part on a steering wheel angle of the equipped vehicle.

15. A driver assistance system as claimed in claim 14, wherein the processor is operable to receive an input corresponding to the steering wheel angle of the equipped vehicle.

16. A driver assistance system as claimed in claim 15, wherein, if the configuration of the vehicle is available with different steering gear ratios, a value is provided in the input when the steering wheel of the equipped vehicle is at full lock, and wherein the processor is further operable to determine information regarding the steering gear ratio of the equipped vehicle based on the input.

17. A driver assistance system, said driver assistance system comprising:

a camera, wherein the camera comprises a lens and an image sensor for capturing image data;

a processor;

a memory, wherein the memory stores a plurality of overlays including at least one first overlay corresponding to a first vehicle configuration and at least one second overlay corresponding to a second vehicle configuration; and

wherein the processor is operable to select a particular overlay from the stored plurality of overlays to display based at least in part on a configuration of the vehicle that is to be equipped with said driver assistance system.

18. A driver assistance system as claimed in claim 17, wherein the configuration of the vehicle is provided as an input to the driver assistance system.

19. A driver assistance system as claimed in claim 17, wherein the plurality of overlays stored in the memory includes overlays relating to predicted vehicle trajectories, and wherein, with a vehicle equipped with the driver assistance system, the processor is operable to select a particular overlay to display based at least in part on a steering wheel angle of the equipped vehicle.

20. A driver assistance system as claimed in claim 19, wherein the processor is operable to receive an input corresponding to the steering wheel angle of the equipped vehicle.

21. A driver assistance system as claimed in claim 20, wherein, if the configuration of the vehicle is available with different steering gear ratios, a value is provided in the input when the steering wheel of the equipped vehicle is at full lock, and wherein the processor is further operable to determine information regarding the steering gear ratio of the equipped vehicle based on the input.

22. A driver assistance system as claimed in claim 17, wherein the plurality of overlays stored in the memory includes at least one common overlay corresponding to both two vehicle configurations.

23. A driver assistance system as claimed in claim 17, wherein the processor determines which overlay to display by accessing a look up table.
