ABSTRACT:
A motor vehicle having a plurality of road engaging wheels (7-10), a braking system (3, 14-18) linked to the wheels (7-10) by which a driver of the vehicle (1) may brake the vehicle, a motive means (50) linked to one or more of the wheels (7-10) by which a driver of the vehicle may control vehicle speed, and a dynamic stability control system that includes a means (12-17, 20-22, 24) for deducing the position and orientation of the vehicle system (12-17, 20-22, 24) for predicting the trajectory (TP) of the motor vehicle (1) with respect to the roadway (4) and for identifying when the predicted trajectory (TP) would place the vehicle in danger, and a wheel slip detection system (14-18, 51) for detecting loss of traction of one or more of the wheels (12-17). The dynamic stability control system monitors wheel slip and the predicted trajectory (TP) of the vehicle (1), and, if loss of wheel traction is detected when the predicted trajectory (TP) would place the vehicle (1) in danger, acts to alter (TC) the predicted trajectory, for example by controlling the braking system (14-18) and/or the motive means (50) in such a way that the identified danger is reduced or eliminated.
