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.
A motor vehicle comprising a plurality of road engaging wheels, and a dynamic stability control system that includes a means for deducing the position and orientation of the vehicle with respect to a roadway on which the vehicle travels, a path prediction system for predicting the trajectory of the motor vehicle with respect to the roadway and for identifying when the predicted trajectory would place the vehicle in danger, and a wheel slip detection system for detecting loss of traction of one or more of the wheels, wherein the dynamic stability control system is arranged to predict the trajectory of the vehicle, determine whether the predicted trajectory would place the vehicle in danger, and, if loss of wheel traction is detected when the predicted trajectory would place the vehicle in danger, to alter the predicted trajectory in such a way that the identified danger is reduced or eliminated.
A motor vehicle according to any foregoing claim further comprising a steering system wherein the dynamic stability control system is arranged to alter the predicted trajectory by altering the steering angle of the vehicle provided by the steering system.
A motor vehicle according to any foregoing claim including a steering system by which the driver may select a steering angle, wherein the dynamic stability control system is responsive also to the selected steering angle so that when the dynamic stability control system acts to alter the predicted trajectory, the trajectory is altered towards the selected steering angle when this corresponds with a trajectory of reduced or eliminated danger.
A motor vehicle according to any foregoing claim, in which the means for deducing the position and orientation of the vehicle with respect to the roadway includes a memory means that stores road layout data for a geographical area in which the vehicle travels.
A method of dynamically controlling the trajectory of a motor vehicle that includes a dynamic stability control system, and a plurality of road engaging wheels, wherein the method comprises the steps of using the dynamic stability control system to:
