Abstract

A system for modifying the handling bias of a vehicle having one or more dynamic parameter sensors (114, 115) which produce sensor signals representative of parameters indicative of the current handling performance of a vehicle, and a vehicle handling performance controller (106) responsive to the or each sensor signal to produce parameter control signals which are applied to parameter control devices to adjust the parameter towards a desired value in relation to the vehicles current handling status, the handling bias modifying system including a signal modifier (506) which receives and modifies one or more of the sensor signals and/or one or more of the parameter control signals.

Claims

1. A system for modifying the handling bias of a vehicle having one or more dynamic parameter sensors which produce sensor signals representative of parameters indicative of the current handling performance of a vehicle, and a vehicle handling performance controller responsive to the or each sensor signal to produce parameter control signals which are applied to parameter control devices to adjust the parameter towards a desired value in relation to the vehicles current handling status, the handling bias modifying system including a signal modifier which receives and modifies one or more of the sensor signals and/or one or more of the parameter control signals.

2. A system as claimed in claim 1, including an in-cockpit modifier controller having one or more control interfaces to permit a driver to adjust the modification of the sensor signals.

3. A system as claimed in claim 2, wherein the modifier controller includes a first interface which is adapted to enable the driver to select the nature of the modification of one or more of the signals.

4. A system as claimed in claim 3, wherein the modifier controller includes a second interface which is adapted to enable the driver to select the magnitude profile of the modification of one or more of the signals.

5. A method of modifying the handling bias of a vehicle having one or more dynamic parameter sensors which produce sensor signals representative of parameters indicative of the current handling performance of a vehicle, and a vehicle handling performance controller responsive to the or each sensor signal to produce parameter control signals which are applied to parameter control devices to adjust the parameter towards a desired value in relation to the vehicles current handling status, method including receiving and modifying one or more of the sensor signals and/or one or more of the parameter control signals.

6. A method as claimed in claim 5, including an in-cockpit modifier controller having one or more control interfaces to permit a driver to adjust the modification of the sensor signals.

7. A method as claimed in claim 6, including providing a first interface which is adapted to enable the driver to select the nature of the modification of one or more of the signals.

8. A method as claimed in claim 7, including providing a second interface which is adapted to enable the driver to select the magnitude profile of the modification of one or more of the signals.

9. A method of retrofitting a handling bias modifier to a vehicle equipped with one or more dynamic parameter sensors which produce sensor signals representative of parameters indicative of the current handling performance of a vehicle, and a vehicle handling performance controller responsive to the or each sensor signal to produce parameter control signals which are applied to parameter control devices to adjust the parameter towards a desired value in relation to the vehicles current handling status, the method including inserting a handling bias modifier between at least one of the sensors and the ESC, and modifying one or more of the sensor signals before applying the modified sensor signal to the vehicle handling performance controller.

10. A method as claimed in claim 9, including providing one or more driver-actuated interface controls to enable the driver to control the nature and/or degree of modification of the sensor signal.

11. An in-cabin vehicle handling bias control arrangement including a bias modifier having at least one interface to permit a driver to select modifications to the input and/or the output signals from a vehicle stability control system.
