Abstract

A system and method for controlling the performance of complex operations on a dashboard-mounted touchscreen in a vehicle moving above a predetermined minimal speed. The system includes a sensor for determining that the touchscreen is intended or going to be touched by driver and/or front seat passenger. A control, responsive to operation of the sensor, disallows or allows the touchscreen to be responsive to a touching. The touchscreen is not allowed to perform a complex operation when the vehicle is moving above the minimal speed if the touchscreen is touched by the driver. The touchscreen is allowed to perform a complex operation when the vehicle is moving above the minimal speed if the touchscreen is not going to be touched by the driver and is touched by the passenger.

Claims

1. A system, comprising:

a sensor that is programmed to determine that an operable dashboard-mounted touchscreen in a moving vehicle is going to be touched by a hand of a driver and/or a hand of a front-seat passenger of said vehicle based on particular proximity of said driver'"'"'s hand and/or said passenger'"'"'s hand to said sensor; and

a control that is programmed to allow or disallow, based on input from said sensor, said touchscreen to be responsive to touching of said touchscreen by said driver'"'"'s hand and/or said passenger'"'"'s hand;

wherein the system includes logic to disable said sensor and said control when said vehicle is moving below a predetermined minimal speed, whereby said operable touchscreen is then fully responsive to touching by said driver'"'"'s hand and/or said passenger'"'"'s hand.

2. The system of claim 1 wherein said sensor is further programmed to determine that said touchscreen is going to be touched by said hand of said driver and wherein said control is further programmed to disallow said touchscreen to be responsive to touching of said touchscreen by said driver'"'"'s hand.

3. The system of claim 2 wherein said touchscreen is centrally located on said dashboard, said driver being located left of said touchscreen and said passenger being located right of said touchscreen and wherein said sensor is located left of said touchscreen.

4. The system of claim 1 wherein said sensor is further programmed to determine that said touchscreen is going to be touched by said hand of said passenger and wherein said control is further programmed to allow said touchscreen to be responsive to touching of said touchscreen by said passenger'"'"'s hand.

5. The system of claim 4 wherein said touchscreen is centrally located on said dashboard, said driver being located left of said touchscreen and said passenger being located right of said touchscreen and wherein said sensor is located right of said touchscreen.

6. The system of claim 1 wherein said sensor is further programmed to determine that said touchscreen is not going to be touched by said hand of said driver and is going to be touched by said hand of said passenger and wherein said control is further programmed to allow said touchscreen to be responsive to touching of said touchscreen by said passenger'"'"'s hand.

7. The system of claim 6 wherein said touchscreen is centrally located on said dashboard, said driver being located left of said touchscreen and said passenger being located right of said touchscreen and wherein said sensor comprises a left-hand sensor and a right hand sensor, said left-hand sensor being located left of said touchscreen and said right-hand sensor being located right of said touchscreen.

8. The system of claim 7 further comprising:

a passenger seat belt buckle switch located in said vehicle; and

buckle switch logic for not permitting said touchscreen to be responsive to touching of said touchscreen by said passenger'"'"'s hand if said passenger seat belt buckle switch is not closed.

9. The system of claim 8 further comprising:

a passenger seat included in said vehicle;

an occupant classification system (OCS) included in said vehicle; and

occupant logic for not permitting said touchscreen to be responsive to touching of said touchscreen by said passenger'"'"'s hand if a signal from said OCS indicates that said passenger is not in said seat.

10. The system of claim 7 further comprising:

a passenger seat included in said vehicle;

an occupant classification system (OCS) included in said vehicle; and

occupant logic for not permitting said touchscreen to be responsive to touching of said touchscreen by said passenger'"'"'s hand if a signal from said OCS indicates that said passenger is not in said seat.

11. The system of claim 1 wherein said sensor is further programmed to determine that said touchscreen is going to be touched by both said hand of said driver and by said hand of said passenger and wherein said control is further programmed to disallow said touchscreen to be responsive to touching of said touchscreen by said passenger'"'"'s hand and/or said driver'"'"'s hand.

12. The system of claim 11 wherein said touchscreen is centrally located on said dashboard, said driver being located left of said touchscreen and said passenger being located right of said touchscreen and wherein said sensor comprises a left-hand sensor and a right hand sensor, said left-hand sensor being located left of said touchscreen and said right-hand sensor being located right of said touchscreen.

13. The system of claim 1 wherein said sensor is an infrared sensor, an active infrared sensor or an ultrasonic sensor.

14. The system of claim 1 wherein touching said touchscreen with respect to a complex touchscreen operation includes one of:

(a) using the touchscreen to enter a destination en route, (b) pairing a Bluetooth phone, (c) adding phonebook contacts or uploading phonebook contacts from a Universal Serial Bus (USB), (d) adding or editing address book entries, (e) enabling Valet Mode, (f) editing wireless settings and (g) editing Artist Alert.

15. A system, comprising:

a sensor that is programmed to determine that an operable dashboard-mounted touchscreen in a moving vehicle is going to be touched by a hand of a driver and/or a hand of a front-seat passenger of said vehicle based on particular proximity of said driver'"'"'s hand and/or said passenger'"'"'s hand to said sensor; and

a control that is programmed to allow or disallow, based on input from said sensor, said touchscreen to be responsive to touching of said touchscreen by said driver'"'"'s hand and/or said passenger'"'"'s hand;

wherein said sensor is further programmed to determine that said touchscreen is not going to be touched by said hand of said driver and is going to be touched by said hand of said passenger and wherein said control is further programmed to allow said touchscreen to be responsive to touching of said touchscreen by said passenger'"'"'s hand;

wherein said touchscreen is centrally located on said dashboard, said driver being located left of said touchscreen and said passenger being located right of said touchscreen and wherein said sensor comprises a left-hand sensor and a right hand sensor, said left-hand sensor being located left of said touchscreen and said right-hand sensor being located right of said touchscreen,

the system further comprising;

a passenger seat belt buckle switch located in said vehicle; and

buckle switch logic for disallowing said touchscreen to be responsive to touching of said touchscreen by said passenger'"'"'s hand if said passenger seat belt buckle switch is not closed.

16. The system of claim 15, further comprising:

a passenger seat included in said vehicle;

an occupant classification system (OCS) included in said vehicle; and

occupant logic for not permitting said touchscreen to be responsive to touching of said touchscreen by said passenger'"'"'s hand if a signal from said OCS indicates that said passenger is not in said seat.

17. The system of claim 16 further comprising:

a passenger seat included in said vehicle;

an occupant classification system (OCS) included in said vehicle; and

occupant logic for not permitting said touchscreen to be responsive to touching of said touchscreen by said passenger'"'"'s hand if a signal from said OCS indicates that said passenger is not in said seat.
