Abstract

A control system for a vehicle subsystem (10) comprises a controller (12) arranged to control operation of the subsystem (10), a user input (16) connected to the system controller (12) and arranged to be operated by a user, and a sensor comprising a transmitter (22) associated with user input (16) and a receiver (26) associated with a first user, whereby the controller uses detection of a signal from the transmitter (22) by the receiver (26) to distinguish between operation of the user input (16) by said first user and operation of the user input by a second user.

Claims

1. A control system for a vehicle subsystem, the control system comprising:

a controller arranged to control operation of the subsystem;

a user input connected to the controller and arranged to be operated by a driver and a passenger of the vehicle to effect operation of the vehicle subsystem;

a sensor comprising a transmitter and a receiver;

wherein one of the transmitter and the receiver is associated with the user input and the other of the transmitter and the receiver is associated with at least one of the driver and the passenger;

wherein upon detection by the receiver of a signal from the transmitter, the controller is arranged to distinguish between operation of the user input by the driver and operation of the user input by the passenger;

wherein the control system includes a display for displaying information to the driver and the system being arranged such that;

when the user input is operated by the driver, the display is operated so as to display said information to the driver; and

when the user input is operated by the passenger, the display is not activated.

2. A system as claimed in claim 1, wherein the display comprises a head-up display arranged to project a display image onto a vehicle windscreen.

3. A system as claimed in claim 1, wherein when the user input is operated by the passenger, an illuminator is operated so as to display said information to the passenger.

4. A system as claimed in claim 1, wherein one of the transmitter and the receiver is in a position arranged to be associated with the driver.

5. A system as claimed in claim 4, wherein one of the transmitter and the receiver is a seat electrode mounted in a seat of the vehicle such that the driver is a person sitting on the seat.

6. A system as claimed in claim 4, wherein one of the transmitter and the receiver is arranged to be mounted in a footwell of the vehicle such that the driver is a person having their feet in the footwell.

7. A system as claimed in claim 1, wherein the user input comprises a movable input member and one of the transmitter and receiver is in communication with the input member.

8. A system as claimed in claim 7 wherein the input member is one of a hand operated input member and a foot operated pedal.

9. A system as claimed in claim 1, wherein one of the transmitter and receiver is mounted adjacent to the user input.

10. A system as claimed in claim 1, wherein the user input is provided in a panel and one of the transmitter and receiver is mounted around the panel.

11. A system as claimed in claim 1, wherein the user input includes a screen including a conductive layer which forms one of the transmitter and receiver.

12. A system as claimed in claim 1, wherein the receiver includes first and second receivers associated with the driver and the passenger respectively, and the controller is arranged to determine which of the driver of the passenger operates the user input based on the signal from the transmitter being received at one of the first and second receivers.

13. A control system for a vehicle subsystem, the control system comprising:

a user input for operation by a driver and a passenger of the vehicle to effect operation of the vehicle subsystem;

a sensor comprising a transmitter and a receiver to detect a signal from the receiver, wherein one of the transmitter and the receiver is associated with the user input and the other of the transmitter and the receiver is associated with at least one of the driver and the passenger;

a head-up display arranged to project a display image onto a vehicle windscreen based on operation of the user input; and

a controller in communication with the user input and the sensor, the controller configured to;

distinguish operation of the user input between the driver the passenger based on the sensor signal;

display the heads-up display image when the user input is operated by the driver; and

prevent display of the heads-up image when the user input is operated by the passenger.

14. A system as claimed in claim 13, wherein the controller is further configured to:

illuminate an illuminator associated with the user input to display information to the passenger when the display of the heads-up image is prevented.

15. A system as claimed in claim 13, wherein one of the transmitter and the receiver is in a position arranged to be associated with the driver.

16. A system as claimed in claim 15, wherein one of the transmitter and the receiver is a seat electrode mounted in a seat of the vehicle such that the driver is a person sitting on the seat.

17. A system as claimed in claim 15, wherein one of the transmitter and the receiver is arranged to be mounted in a footwell of the vehicle such that the driver is a person having their feet in the footwell.

18. A system as claimed in claim 13, wherein the receiver includes first and second receivers associated with the driver and the passenger respectively, and the controller is configured to determine which of the driver of the passenger operates the user input based on the signal from the transmitter being received at one of the first and second receivers.
