Abstract
A traction control system for a motor vehicle includes a controller configured to initiate a traction control intervention at one or more vehicle wheels. The controller is configured to inhibit the traction control intervention in dependence on a reduced wheel load condition in said one or more wheels. The reduced wheel load condition is identified based on at least one of a signal indicative of vehicle pitch and a signal indicative of vehicle heave.
Claims30
A traction control system for a motor vehicle, the traction control system comprising an electronic controller configured to identify a wheelslip condition and initiate a traction control intervention at one or more vehicle wheels in dependence on the wheelslip condition, wherein the electronic controller is configured to modify the traction control intervention in dependence on a reduced wheel load condition in said one or more wheels, the reduced wheel load condition being identified based on at least one of:
- a signal indicative of vehicle pitch;
- and a signal indicative of vehicle heave, wherein the controller is configured to modify the traction control intervention by inhibiting the traction control intervention.

A method of controlling traction at one or more wheels of a motor vehicle, the method comprising:
- identifying a wheelslip condition in said one or more wheels, identifying a reduced wheel load condition in said one or more wheels based on at least one of vehicle pitch data and vehicle heave data;
- and determining a modified traction control intervention in dependence on the wheelslip condition and the reduced wheel load condition, wherein determining a modified traction control intervention comprises inhibiting the traction control intervention.

An electronic controller for a vehicle having a storage medium associated therewith storing instructions that when executed by the controller cause the determination of a modified traction control intervention in accordance with a method comprising:
- identifying a wheelslip condition in said one or more wheels, identifying a reduced wheel load condition in said one or more wheels based on at least one of vehicle pitch data and vehicle heave data;
- and determining a modified traction control intervention in dependence on the wheelslip condition and the reduced wheel load condition, wherein the controller is configured to modify the traction control intervention by inhibiting the traction control intervention.
