Abstract

A control system (200; 200′) for enabling operation of a vehicle (300), the control system (200; 200′) comprising: a gaze sensing component (120); a processor (140) communicatively coupled to the gaze sensing component (120); and a controller (160) communicatively coupled to the processor (140); wherein: the gaze sensing component (120) is configured to detect a gaze characteristic of a user of the vehicle (300) and send data representative of the gaze characteristic to the processor (140); the processor (140) is configured to identify a primary indication of intent of the user to operate the vehicle (300) when the user gaze characteristic complies with a predetermined gaze characteristic for a first predetermined time period; and the controller (160) is configured to generate an activation signal (150) to enable operation of the vehicle (300) in dependence on the identified primary indication of intent.

Claims

1. A control system for enabling operation of a vehicle, the control system comprising:

a gaze sensing component;

a processor communicatively coupled to the gaze sensing component; and

a controller communicatively coupled to the processor;

wherein;

the gaze sensing component is configured to detect a gaze characteristic of a user of the vehicle and send data representative of the gaze characteristic to the processor;

the processor is configured to identify a primary indication of intent of the user to operate the vehicle when the user gaze characteristic complies with a predetermined gaze characteristic for a first predetermined time period;

the controller is configured to generate an activation signal to enable operation of the vehicle in dependence on the identified primary indication of intent;

the controller is further configured to generate a feedback signal to enable feedback to be provided to the user based on the user gaze characteristic; and

upon identification by the processor that the user gaze characteristic complies with the predetermined gaze characteristic, the controller is configured to generate a feedback signal to enable feedback representative of approaching a threshold associated with the first predetermined time period.

2. The control system of claim 1, wherein the feedback is at least one of the following:

visual feedback, audio feedback, and haptic feedback.

3. The control system of claim 1, wherein upon identification by the processor that the user gaze characteristic does not comply with the predetermined gaze characteristic within the first predetermined time period, the controller is configured to reset the feedback signal.

4. The control system of claim 1, wherein the user gaze characteristic comprises eye movement of the user and the predetermined gaze characteristic comprises predetermined eye movement of the user.

5. The control system of claim 1, wherein the gaze characteristic of a user comprises a gaze direction of the user and the predetermined gaze characteristic comprises a predetermined gaze direction to a predetermined target location T.

6. The control system of claim 5, wherein the predetermined target location T is an interior location of the vehicle.

7. The control system of claim 6, wherein the interior location is associated with one of the following:

an instrument cluster, a steering wheel, a mirror, a dashboard, a glove box, a screen, a portion of a windshield, or an air vent.

8. The control system of claim 1, wherein the user gaze characteristic comprises an iris feature of the user and the predetermined gaze characteristic comprises a predetermined iris feature.

9. The control system of claim 1, wherein the gaze sensing component comprises at least one camera.

10. The control system of claim 1, further comprising an input sensing component communicatively coupled to the processor;

wherein;

the input sensing component is configured to detect an input from the user and send data representative of the input to the processor;

the processor is configured to identify a secondary indication of intent of the user to operate the vehicle when the input from the user complies with a predetermined input condition for a second pre-determined time period; and

the controller is configured to generate the activation signal in dependence on the primary indication of intent and the secondary indication of intent.

11. The control system of claim 10, wherein the input sensing component is one of the following:

a capacitive sensor;

a pressure sensor; and

an audio sensor.

12. The control system of claim 10, wherein the input sensing component is associated with one of the following:

a clutch pedal;

a brake pedal, and a steering wheel.

13. The control system of claim 1, further comprising a pre-controller, wherein the pre-controller is configured to identify an authorised user within the vehicle;

and wherein the controller is configured to generate the activation signal after the pre-controller identifies an authorised user.

14. The control system of claim 13, wherein the pre-controller is configured to detect an identification module within the vehicle.

15. A vehicle comprising the control system of claim 1.

16. A method for enabling operation of a vehicle, the method comprising:

detecting a user gaze characteristic of a user of the vehicle;

identifying a primary indication of intent of the user to operate the vehicle when the user gaze characteristic complies with a predetermined gaze characteristic for a first predetermined time period;

generating an activation signal to enable operation of the vehicle in dependence on the primary indication of intent;

generating a feedback signal to enable feedback to be provided to the user based on the user gaze characteristic; and

upon identification by the processor that the user gaze characteristic complies with the predetermined gaze characteristic, generating a feedback signal to enable feedback representative of approaching a threshold associated with the first predetermined time period.

17. The method of claim 16, further comprising:

detecting an input from the user of the vehicle;

identifying a secondary indication of intent of the user to operate the vehicle when the input from the user complies with a predetermined input condition for a second predetermined time period; and

generating the activation signal to enable operation of the vehicle in dependence on the primary indication of intent and the secondary indication of intent.

19. A computer program product comprising instructions which, when executed by a computer, cause the computer to perform the method of claim 16.

20. A non-transitory computer-readable medium having stored thereon the computer program product of claim 19.

18. A controller for a control system enabling operation of a vehicle, the controller configured to:

receive an input signal indicative of a primary indication of intent of a user to operate the vehicle, wherein the primary indication of intent is determined when a user gaze characteristic complies with a predetermined gaze characteristic for a first predetermined time period;

generate an activation signal to enable operation of the vehicle in dependence on the received input signal; and

generate a feedback signal to enable feedback representative of approaching a threshold associated with the first predetermined time period.
