Abstract

A vehicle having a dynamics control system, the vehicle comprising: a first set comprising multiple adjustable sub-systems that affect the performance of the vehicle'"'"'s powertrain; a second set comprising multiple adjustable sub-systems that affect the vehicle'"'"'s handling; a dynamics user interface including a first input device and a second input device; and a dynamics controller coupled to the user interface and configured to adjust the operation of the sub-systems of the first set in dependence on the first input device and to adjust the operation of the sub-systems of the second set in dependence on the second input device.

Claims

1. A vehicle having a dynamics control system, the vehicle comprising:

a first set comprising multiple adjustable sub-systems that affect the performance of the vehicle'"'"'s powertrain;

a second set comprising multiple adjustable sub-systems that affect the vehicle'"'"'s handling;

a dynamics user interface including a first input device and a second input device;

wherein the first input device is a control and the second input device is a control and

a dynamics controller coupled to the user interface and configured to adjust the operation of the sub-systems of the first set in dependence on the first input device and to adjust the operation of the sub-systems of the second set in dependence on the second input device.

2. A vehicle as claimed in claim 1, wherein the dynamics controller is configured to adjust the operation of the sub-systems of the first set independently of the second input device and to adjust the operation of the sub-systems of the second set independently of the first input device.

3. A vehicle as claimed in claim 1, wherein the first input device has two or more available states, and the dynamics controller is configured to adjust the operation of the sub-systems of the first set in dependence on the state of the first input device.

4. A vehicle as claimed in claim 1, wherein the second input device has two or more available states, and the dynamics controller is configured to adjust the operation of the sub-systems of the second set in dependence on the state of the second input device.

5. A vehicle as claimed in claim 1, wherein the sub-systems of the first set comprise two or more of:

engine,

gearbox,

valving in exhaust.

6. A vehicle as claimed in claim 1, wherein the sub-systems of the second set comprise two or more of:

suspension,

variable aerodynamic device,

stability control system,

traction control system,

steering feedback system,

brake system.

7. A vehicle as claimed in claim 1, wherein

the dynamics user interface comprises a third input device;

the dynamics controller is operable in a first mode in which the dynamics controller is configured to adjust the operation of the sub-systems of the first set in dependence on the first input device and to adjust the operation of the sub-systems of the second set in dependence on the second input device, and a second mode in which the dynamics controller is configured to set the operation of the sub-systems of the first set independently of the first input device and to set the operation of the sub-systems of the second set independently of the second input device;

the dynamics controller being configured to operate in one of the first and the second modes in dependence on the third input device.

8. A vehicle as claimed in claim 7, comprising a fourth input device to which a gearbox of the car is responsive to switch from manual mode to automatic mode, the gearbox being further configured to operate only in automatic mode, irrespective of the fourth input device, when the dynamics controller is operating in the second mode.

9. A vehicle as claimed in claim 7, comprising a fifth input device to which a variable aerodynamic element of the car is responsive to enable and disable functions of the variable operation of the variable aerodynamic element, the variable aerodynamic element being further configured such that those functions are disabled, irrespective of the fifth input device, when the dynamics controller is operating in the second mode.

10. A vehicle as claimed in claim 7, wherein the dynamics controller is configured to operate by default in the second mode when the vehicle is started.

11. A vehicle as claimed in claim 7, wherein the dynamics controller is configured to, in the second mode, set the sub-systems of the first set and the second set to operating characteristics that are adapted for casual driving.

12. A vehicle as claimed in claim 1, wherein

the dynamics user interface comprises a sixth input device;

and the dynamics controller is operable in a first mode in which the dynamics controller is configured to adjust the operation of the sub-systems of the first set in dependence on the first input device and to adjust the operation of the sub-systems of the second set in dependence on the second input device, and a third mode in which the dynamics controller is configured to set the sub-systems of the first set and the second set to operating characteristics that are adapted for winter driving.

13. A vehicle as claimed in claim 1, wherein the first input device has three or more available states.

14. A vehicle as claimed in claim 1, wherein the second input device has three or more available states.

15. A vehicle as claimed in claim 1, wherein the first input device and the second input device are multi-state knobs.
