Abstract

Methods, systems, and apparatus for enabling telematics in a vehicle. A telematics system for enabling telematics in a vehicle including multiple user interface elements that operate one or more telematics devices. The multiple user interface elements include a respective user interface element. The telematics system includes one or more sensors configured to provide driver control information and passenger presence information and an electronic control unit. The electronic control unit is connected to the one or more sensors. The electronic control unit is configured to obtain the passenger presence information and the driver control information. The electronic control unit is configured to enable the respective user interface element during operation of the vehicle based on the driver control information and the passenger presence information.

Claims

1. A telematics system for enabling telematics in a vehicle, comprising:

a plurality of user interface elements that provide access to features of one or more telematics devices of the vehicle, the plurality of user interface elements including a respective user interface element that accesses a feature of a telematics device, the respective user interface element being in an enabled mode where the respective user interface element is accessible or a disabled mode where the respective user interface element is inaccessible;

one or more sensors configured to provide passenger presence information including an indication of a number of seat belts that are fastened; and

an electronic control unit connected to the one or more sensors and configured to;

obtain, from the one or more sensors, the passenger presence information, and

set a configuration setting for the respective user interface element to the enabled mode from the disabled mode during operation of the vehicle based on the indication of the number of seat belts that are fastened.

2. The telematics system of claim 1, wherein the one or more sensors further include at least one of a load sensor located in proximity of a passenger seat of the vehicle, one or more hand position sensors located on a steering wheel of the vehicle, or one or more cameras that recognize a passenger is in the vehicle, wherein the electronic control unit is configured to obtain, from the one or more sensors, driver control information.

3. The telematics system of claim 2, wherein the driver control information includes an indication of a number of hands on the steering wheel and the passenger presence information further includes a measure of a load on the passenger seat.

4. The telematics system of claim 3, wherein the electronic control unit is configured to set the configuration setting for the respective user interface element to the enabled mode from the disabled mode during operation of the vehicle further based on the number of hands on the steering wheel and the measure of the load on the passenger seat.

5. The telematics system of claim 2, wherein the driver control information includes a position of one or more hands on a steering wheel.

6. The telematics system of claim 2, wherein the one or more sensors further include at least one of a steering wheel alignment sensor that detects a steering wheel angle of the steering wheel of the vehicle or a vehicle speed sensor that detects a vehicle speed of the vehicle, wherein the driver control information includes the steering wheel angle and the vehicle speed.

7. The telematics system of claim 1, wherein the respective user interface element is configured to receive user input on a keypad that dials a mobile device.

8. The telematics system of claim 1, further comprising:

a memory configured to store one or more driver profiles, wherein each driver profile of the one or more driver profiles stores a configuration setting for each user interface element of the plurality of user interface elements.

9. The telematics system of claim 8, wherein the electronic control unit is configured to:

determine an identity of a driver of the vehicle;

obtain, from the memory, a respective driver profile of the one or more driver profiles based on the identity of the driver; and

set the configuration setting for the respective user interface element to the enabled mode from the disabled mode during operation of the vehicle further based on the respective driver profile.

10. A method for enabling telematics in a vehicle, comprising:

determining an identity of a driver of the vehicle;

obtaining a driver profile based on the identity of the driver;

setting a configuration setting for a respective user interface element of a plurality of user interface elements to a disabled mode at a beginning of a current driving session based on the driver profile;

obtaining passenger presence information including an indication of a number of seat belts that are fastened;

determining that a passenger is present based on the indication of the number of seat belts that are fastened; and

setting the configuration setting for the respective user interface element to the enabled mode from the disabled mode in response to determining that the passenger is present.

11. The method of claim 10, further comprising:

determining that a driver has no control of the vehicle; and

setting the configuration setting for the respective user interface element to the disabled mode in response to determining that the driver has no control of the vehicle.

12. The method of claim 11, wherein determining that the passenger is present is further based on a load on a passenger seat being greater than a threshold weight.

13. The method of claim 12, wherein the driver has no control of the vehicle when a speed of the vehicle is greater than a maximum speed limit.

14. The method of claim 10, further comprising:

obtaining driver control information, wherein the driver control information includes at least one of steering angle data, speed data, or hand position data and the passenger presence information further includes passenger load data.

15. The method of claim 14, further comprising:

determining that the vehicle is in control based on the driver control information.

16. A telematics system for enabling telematics in a vehicle, comprising:

a user interface having one or more user interface elements, a respective user interface element of the one or more user interface elements corresponding to a feature of the vehicle and having a configuration setting in an enabled mode that enables the user interface element or in a disabled mode that disables the user interface element;

one or more sensors configured to provide driver control information and passenger presence information including an indication of a number of seat belts that are fastened; and

an electronic control unit connected to at least one of the user interface or the one or more sensors and configured to;

determine that a driver has control of the vehicle based on the driver control information,

determine that a passenger is in the vehicle based on the passenger presence information including the indication of the number of seat belts that are fastened, and

set the configuration setting of the user interface element to the enabled mode from the disabled mode when the number of seat belts that are fastened is greater than or equal to two.

17. The telematics system of claim 16, wherein the driver control information indicates that two hands are on a steering wheel.
