Abstract

Disclosed herein are a haptic feedback method and apparatus for a vehicle. The haptic feedback apparatus an accelerator pedal sensor unit, a control unit, and an output unit. The accelerator pedal sensor unit measures the angle of a vehicle accelerator pedal. The control unit determines whether the haptic feedback is required, using the measured angle of the vehicle accelerator pedal. The output unit deliver the haptic feedback to a user depending on the results of the determination.

Claims

1. A haptic feedback apparatus for a vehicle, comprising:

an accelerator pedal sensor unit configured to measure an angle of a vehicle accelerator pedal;

a control unit configured to determine whether the haptic feedback is required, using the measured angle of the vehicle accelerator pedal; and

an output unit configured to deliver the haptic feedback to a user depending on results of the determination,

wherein the control unit determines whether the haptic feedback is required or the control unit generates the haptic feedback corresponding to each of the predetermined vehicle accelerator pedal angle ranges,

wherein the control unit includes

an engine RPM increment comparison unit configured to measure a vehicle engine RPM increment using the RPM of the vehicle engine and to determine whether the measured vehicle engine RPM increment exceeds a predetermined vehicle engine RPM increment, and

an engine RPM increment processing unit configured to generate the haptic feedback corresponding to the predetermined vehicle engine RPM increment.

2. The haptic feedback apparatus of claim 1, further comprising a display unit configured to visually display the measured angle of the vehicle accelerator pedal on a dashboard.

3. The haptic feedback apparatus of claim 2, wherein the control unit further includes:

an accelerator pedal angle comparison unit configured to determine whether the measured angle of the vehicle accelerator pedal falls within a predetermined vehicle accelerator pedal angle range; and

an accelerator pedal angle processing unit configured to generate the haptic feedback corresponding to the predetermined vehicle accelerator pedal angle range.

4. The haptic feedback apparatus of claim 3, wherein the accelerator pedal angle processing unit generates the haptic feedback to the output unit if the measured angle of the vehicle accelerator pedal falls within the predetermined vehicle accelerator pedal angle range.

5. The haptic feedback apparatus of claim 4, wherein the haptic feedback is feedback in the form of a vibration or a click of the vehicle accelerator pedal.

6. The haptic feedback apparatus of claim 3, further comprising an engine sensor unit configured to measure an RPM of a vehicle engine.

7. The haptic feedback apparatus of claim 6, wherein the engine RPM increment processing unit generates the haptic feedback to the output unit if the vehicle engine RPM increment exceeds the predetermined vehicle engine RPM increment.

8. The haptic feedback apparatus of claim 7, wherein the haptic feedback is feedback in the form of a vibration or a click of the vehicle accelerator pedal.

9. A haptic feedback method for a vehicle, comprising:

measuring an angle of a vehicle accelerator pedal;

determining whether haptic feedback is required, using the measured angle of the vehicle accelerator pedal; and

delivering the haptic feedback to a user depending on results of the determination,

wherein the determining whether the haptic feedback is required includes determining whether the haptic feedback is required or generating the haptic feedback corresponding to each of the predetermined vehicle accelerator pedal angle ranges,

wherein determining whether the haptic feedback is required includes

measuring a vehicle engine RPM increment using the RPM of the vehicle engine,

determining whether the measured vehicle engine RPM increment exceeds a predetermined vehicle engine RPM increment, and

generating the haptic feedback corresponding to the predetermined vehicle engine RPM increment.

10. The haptic feedback method of claim 9, further comprising visually displaying the measured angle of the vehicle accelerator pedal on a dashboard.

11. The haptic feedback method of claim 10, wherein determining whether the haptic feedback is required further includes:

determining whether the measured angle of the vehicle accelerator pedal falls within a predetermined vehicle accelerator pedal angle range; and

generating the haptic feedback corresponding to the predetermined vehicle accelerator pedal angle range.

12. The haptic feedback method of claim 11, wherein generating the haptic feedback corresponding to the predetermined vehicle accelerator pedal angle includes generating the haptic feedback if the angle of the vehicle accelerator pedal falls within the predetermined vehicle accelerator pedal angle range.

13. The haptic feedback method of claim 12, wherein the haptic feedback is feedback in the form of a vibration or a click of the vehicle accelerator pedal.

14. The haptic feedback method of claim 11, further comprising measuring an RPM of a vehicle engine.

15. The haptic feedback method of claim 14, wherein generating the haptic feedback corresponding to the predetermined vehicle engine RPM increment includes generating the haptic feedback if the vehicle engine RPM increment exceeds the predetermined vehicle engine RPM increment.

16. The haptic feedback method of claim 15, wherein the haptic feedback is feedback in the form of a vibration or a click of the vehicle accelerator pedal.
