TRACTION CONTROL CONSIDERING WHEEL SLIP, PITCH AND HEAVE

摘要

A traction control system for a motor vehicle comprises a controller configured to initiate a traction control intervention at one or more vehicle wheels based on wheel slip. The 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 is identified based on at least one of a signal indicative of vehicle pitch; and a signal indicative of vehicle heave. Aspects of the invention also relate to vehicles comprising such systems, methods of controlling traction, and to related electronic controllers, software and processors.
