Abstract

Claims (52)

1. A vehicle comprising:

a light bar disposed at a vehicle structural component in a vehicle interior portion, wherein the light bar is configured to illuminate a driver's upper body;

a first vehicle sensor configured to detect a driver's gesture in the vehicle interior portion; and

a processor configured to:

obtain inputs associated with the driver's gesture from the first vehicle sensor;

determine that the driver's gesture is a predefined gesture based on the inputs; and

switch an operational state of the light bar from a deactivated state to an activated state to enable a user outside the vehicle to view the driver's gestures.

2. The vehicle of claim 1 , wherein the vehicle structural component is a vehicle A-pillar.

3. The vehicle of claim 1 , wherein the first vehicle sensor is located in proximity to a vehicle instrument cluster.

4. The vehicle of claim 1 , wherein the first vehicle sensor is a motion sensor.

5. The vehicle of claim 1 , further comprising a memory configured to store an information associated with a plurality of predefined gestures.

6. The vehicle of claim 5 , wherein the processor is further configured to:

obtain the information associated with the plurality of predefined gestures from the memory;

compare the driver's gesture with the plurality of predefined gestures based on the information; and

determine that the driver's gesture is equivalent to the predefined gesture, of the plurality of predefined gestures, based on the comparison.

7. The vehicle of claim 1 , wherein the processor is further configured to:

calculate a time duration responsive to switching the operational state of the light bar from the deactivated state to the activated state;

compare the time duration with a first threshold value; and

switch the operational state of the light bar from the activated state to the deactivated state when the time duration exceeds the first threshold value.

8. The vehicle of claim 1 , further comprising a power supply configured to supply power to the light bar, wherein the processor is configured to control the power supply to switch the operational state.

9. The vehicle of claim 1 , wherein the light bar comprises a light-emitting diode (LED) array comprising a plurality of LEDs.

10. The vehicle of claim 1 , further comprising a second vehicle sensor configured to detect a user presence in proximity to the vehicle.

11. The vehicle of claim 10 , wherein the processor is further configured to:

obtain second inputs from the second vehicle sensor;

determine the user presence in proximity to the vehicle based on the second inputs; and

obtain the inputs associated with the driver's gesture from the first vehicle sensor responsive to determining the user presence in proximity to the vehicle.

12. The vehicle of claim 1 , wherein the processor is further configured to:

determine that a light intensity in the vehicle interior portion is less than a second threshold value responsive to determining that the driver's gesture is equivalent to the predefined gesture; and

obtain the inputs associated with the driver's gesture from the first vehicle sensor responsive to determining that the light intensity in the vehicle interior portion is less than the second threshold value.

13. A method comprising:

obtaining, by a processor, inputs associated with a driver's gesture from a first vehicle sensor of a vehicle, wherein the first vehicle sensor is configured to detect the driver's gesture in a vehicle interior portion;

determining, by the processor, that the driver's gesture is a predefined gesture based on the inputs; and

switching, by the processor, an operational state of a light bar from a deactivated state to an activated state to enable a user outside the vehicle to view the driver's gestures, wherein the light bar disposed at a vehicle structural component in the vehicle interior portion, and wherein the light bar is configured to illuminate a driver's upper body.

14. The method of claim 13 , wherein the vehicle structural component is a vehicle A-pillar.

15. The method of claim 13 , wherein the first vehicle sensor is located in proximity to a vehicle instrument cluster.

16. The method of claim 13 , further comprising:

obtaining an information associated with a plurality of predefined gestures from a memory;

comparing the driver's gesture with the plurality of predefined gestures based on the information; and

determining that the driver's gesture is equivalent to the predefined gesture, of the plurality of predefined gestures, based on the comparison.

17. The method of claim 13 , further comprising:

calculating a time duration responsive to switching the operational state of the light bar from the deactivated state to the activated state;

comparing the time duration with a first threshold value; and

switching the operational state of the light bar from the activated state to the deactivated state when the time duration exceeds the first threshold value.

18. The method of claim 13 , further comprising controlling a power supply to switch the operational state, wherein the power supply is configured to supply power to the light bar.

19. The method of claim 13 , further comprising:

obtaining second inputs from a second vehicle sensor configured to detect a user presence in proximity to the vehicle;

determining the user presence in proximity to the vehicle based on the second inputs; and

obtaining the inputs associated with the driver's gesture from the first vehicle sensor responsive to determining the user presence in proximity to the vehicle.

20. A non-transitory computer-readable storage medium having instructions stored thereupon which, when executed by a processor, cause the processor to:

obtain inputs associated with a driver's gesture from a first vehicle sensor of a vehicle, wherein the first vehicle sensor is configured to detect the driver's gesture in a vehicle interior portion;

determine that the driver's gesture is a predefined gesture based on the inputs; and

switch an operational state of a light bar from a deactivated state to an activated state responsive to determining that the driver's gesture is equivalent to the predefined gesture, to enable a user outside the vehicle to view the driver's gestures, wherein the light bar disposed at a vehicle structural component in the vehicle interior portion, and wherein the light bar is configured to illuminate a driver's upper body.
