Abstract

A method of controlling at least one anti-roll bar actuator on board a vehicle. The method controls the at least one anti-roll actuator as a function of a measurement of lateral acceleration of the vehicle and controls the vehicle as a function of a value of a static gain in relation to a transfer function between an angle of a vehicle steering control member and a rate of yaw of the vehicle.

Claims

1-9. -9. (canceled)

10. A method of controlling a vehicle, comprising:

controlling at least one anti-roll actuator as a function of a measurement of a lateral acceleration of the vehicle; and

performing the controlling as a function of a value of a static gain of a transfer function in relation to an angle of a steering control of the vehicle and a rate of yaw of the vehicle.

11. The method as claimed in claim 10, wherein the controlling is performed as a function of a longitudinal speed of the vehicle.

12. The method as claimed in claim 10, further comprising determining a longitudinal speed of the vehicle based on data provided by an antilock braking system.

13. The method as claimed in claim 10, further comprising determining the static gain as a function of a longitudinal speed of the vehicle.

14. The method as claimed in claim 10, wherein the static gain is a reference static gain.

15. The method as claimed in claim 10, further comprising determining a control value to be input into the at least one actuator using a map.

16. The method as claimed in claim 15, wherein the control value is determined such that the control value falls between two predetermined limits.

17. The method as claimed in claim 10, further comprising determining an anti-roll apportioning factor so that an anti-roll effect can be split between front and rear anti-roll actuators.

18. A vehicle comprising:

at least one anti-roll actuator; and

a control member,

wherein the control member is configured to control the at least one actuator as a function of a measurement of a lateral acceleration of the vehicle, and as a function of a value of a static gain of a transfer function in relation to an angle of a steering control of the vehicle and a rate of yaw of the vehicle.
