Abstract

A driver assistance detection system and method for determining levels of functionality of an interactive device in a vehicle are provided. The driver assistance detection system comprises a vision-based detection device, a processing device, and an interactive device. The vision-based detection device is configured to visually detect objects, recognize whether the object is an object of interest, and then obtain data regarding a status of the object. The processing device is configured to receive data from the vision-based detection device, run a set of instructions and switch the interactive device between a first mode and a second mode. The interactive device is configured to have at least two modes, wherein the second mode has reduced functionality relative to the first mode.

Claims

1. A driver assistance detection system for a vehicle having a driver, the system comprising:

a vision-based detection device, wherein the vision-based detection device is configured to visually detect an object and visually obtain data regarding a status of the object;

an interactive device having a first mode and a second mode, wherein the second mode is configured to have reduced functionality relative to the first mode;

a processing device, wherein the processing device is configured to receive data regarding the status of the object and output one of the first mode and the second mode for the operation of the interactive device based at least in part on the data regarding the status of the object obtained from the vision-based detection device; and

a speed detection device configured to provide data regarding a speed of the vehicle, and wherein the processing device is configured to receive the data regarding the speed of the vehicle from the speed detection device and switch the interactive device between the first mode and the second mode based further on the data regarding the speed of the vehicle;

wherein the object is a traffic signal and the status of the traffic signal to be obtained by the vision-based detection device is red, yellow, or green; and

wherein the processing device is configured to output the first mode for operation of the interactive device when the status of the traffic signal is red and the speed of the vehicle is about zero.

2. A system according to claim 1, further comprising a vehicle positioning device, wherein:

the vehicle positioning device is configured to provide data regarding a known location of the object; and

the vision-based detection device is configured to receive the data regarding the known location of the object.

3. A system according to claim 1, wherein the processing device is integrated with a vehicle telematic system.

4. A system according to claim 1, wherein the vision-based detection device is configured to detect the object in a field of view forward of the vehicle.

5. A system according to claim 1, further comprising a plurality of vision-based detection devices, wherein the plurality of vision-based detection devices have a plurality of corresponding fields of view.

6. A system according to claim 5, wherein at least one of the plurality of vision-based detection devices comprises a first vision-based detection device configured to detect the object in a first field of view forward of the vehicle, and wherein at least one of the plurality of vision-based detection devices comprises a second vision-based detection device configured to detect the object in a second field of view rearward of the vehicle.

7. A system according to claim 1, wherein the interactive device is further configured to alert the driver when the operation of the interactive device shifts from the first mode to the second mode and the interactive device is configured to be operable in the first mode only if the speed of the vehicle is about zero.

8. A system according to claim 1, wherein the interactive device is configured to be operable only in the second mode if the speed of the vehicle is greater than about zero.

9. A system according to claim 1, wherein the processing device is configured to output the second mode for operation of the interactive device when the status of the traffic signal is not red.

10. A system according to claim 1, wherein the object is a railroad crossing signal and the status of the traffic signal to be obtained by the vision-based detection device is flashing lights or non-flashing lights.

11. A system according to claim 10, wherein the processing device is configured to output the first mode for operation of the interactive device when the status of the railroad crossing signal is flashing and the speed of the vehicle is about zero.

12. A system according to claim 10, wherein the processing device is configured to output the second mode for operation of the interactive device when the status of the railroad crossing signal is not flashing.

13. A system according to claim 1, wherein the object is a construction zone warning sign and the status of the construction zone warning sign to be obtained by the vision-based detection device is flashing lights, non-flashing lights, or arrow lights.

14. A system according to claim 1, wherein the object is an emergency vehicle and the status of the emergency vehicle to be obtained by the vision-based detection device is flashing lights or non-flashing lights.

15. A driver assistance detection system for a vehicle having a driver, the system comprising:

a vision-based detection device, wherein the vision-based detection device is configured to visually detect an object and visually obtain data regarding a status of the object;

an auxiliary receiving device, wherein the auxiliary receiving device is configured to receive a wireless signal encoded with auxiliary data regarding a status of the object from an object status transmitting device located proximate to the object;

an interactive device having a first mode and a second mode, wherein the second mode is configured to have reduced functionality relative to the first mode; and

a processing device, wherein the processing device is configured to receive data regarding the status of the object and auxiliary data regarding the status of the object and output one of the first mode and the second mode for operation of the interactive device based at least in part on the data regarding the status of the object or the auxiliary data regarding the status of the object.

16. A method for assisting a driver of a vehicle, comprising:

scanning the surroundings of the vehicle with a vision-based detection device for an object;

visually detecting an object having more than one status;

visually detecting a first status of the object with the vision-based detection device;

determining if the first status of the object meets a predefined criteria;

outputting one of a first mode and a second mode for operation of an interactive device based at least in part on the first status of the object wherein the second mode is configured to have reduced functionality relative to the first mode and, wherein the interactive device is enabled to operate in the first mode only if the first status of the object meets the predefined criteria;

visually monitoring the object to detect a change in the status of the object from the first status to a second status;

determining if the second status of the object meets the predefined criteria;

and outputting one of the first mode and the second mode for operation of the interactive device based at least in part on the second status of the object, wherein the interactive device is enabled to operate in the first mode only if the second status of the object meets the predefined criteria.

17. The method according to claim 16, further comprising:

detecting a speed of the vehicle with a speed detection device; and

enabling the interactive device to be operable in the first mode only if the speed of the vehicle is about zero.
