Abstract: A vehicle speed control system that carries out a method of receiving a user input of a target set-speed at which the vehicle is intended to travel and applying torque to the at least one of the vehicle wheels for propelling the vehicle at a vehicle control speed. The user input is received via an input device that enables the user to incrementally increase the target set-speed by pressing and holding a target set-speed + button. The system includes a controller configured to incrementally increase the target set-speed while the set-speed + button is held, and, once the set-speed + button is released the controller is configured to continue to increase the target set-speed by a value determined by the controller in dependence on at least one of the instantaneous vehicle speed and the terrain over which the vehicle is travelling.

Abstract: A vehicle control system for at least one vehicle subsystem of a vehicle; the vehicle control system comprising a subsystem controller for initiating control of the or each of the vehicle subsystems in a selected one of a plurality of different subsystem control modes, each of which corresponds to one or more different driving conditions for the vehicle. Evaluation means are provided for evaluating one or more driving condition indicators to determine the extent to which each of the subsystem control modes is appropriate and for providing an output to the subsystem controller that is indicative of the control mode which is most appropriate. This may be an evaluation means for calculating the probability that the or each of the subsystem control modes is appropriate. Automatic control means may be operable in an automatic response mode to select an appropriate one of the subsystem control modes in dependence on the output.

Abstract: A method for operating a speed control system of a vehicle is provided. The method comprises identifying a torque required to achieve a desired operating parameter of the vehicle. The method further assessing whether the required torque exceeds a predetermined torque limit, and when it does, determining if it is appropriate to increase the torque limit. When it is determined that it is appropriate to do so, the method further comprises increasing the predetermined torque limit. A speed control system of a vehicle comprising an electronic control unit configured to: determine a torque required to achieve a desired operating parameter of the vehicle, assess whether the required torque exceeds a predetermined torque limit; when the torque exceeds the torque limit, determine if it is appropriate to increase the torque limit; and when it is determined that it is appropriate to do so, increase the torque limit, is also provided.

Abstract: A vehicle control system having a subsystem controller for initiating control of a first group of at least one vehicle subsystem in a selected one of a plurality of subsystem control modes each corresponding to one or more different driving conditions; and an estimator module for evaluating at least one driving condition indicator to determine the extent to which each of the subsystem control modes is appropriate and for providing an output indicative of the subsystem control mode that is most appropriate. The estimator module is configured to increase the probability to which the at least one off-road driving mode is determined appropriate in dependence on at least one terrain indicator. In an automatic response mode the subsystem controller selects the most appropriate one of the subsystem control modes for each subsystem of the first group in dependence on the output.

Abstract: A method of setting a vehicle in motion over a driving surface and/or maintaining motion of said vehicle over the driving surface implemented by a control system, said method comprising initiating motion control, initiating motion control comprising: commanding by the control system application of brake torque and drive torque to one or more wheels such that the vehicle is held stationary; subsequently initiating motion from rest while brake torque continues to be applied to the one or more wheels. The strategy may also be implemented to maintain vehicle progress on low friction surfaces. The vehicle driver may be commanded to vary a control input, such as accelerator pedal position, in order to facilitate the maintaining of progress.
