    Abstract: A control system (300) configured to control an active suspension system (104) of a vehicle (100), the control system comprising one or more controller (301), wherein the control system is configured to: determine (702) that the vehicle is travelling on or approaching repeating surface undulations; determine (709) vehicle speed; determine (708) an indication of surface wavelength of the repeating surface undulations; and control (722, 728) the active suspension system to control at least one of a leading wheel suspension frequency and a trailing wheel suspension frequency in dependence on the vehicle speed and surface wavelength.

    Abstract: A speed control system for a vehicle. The speed control system has a torque control for automatically causing application of positive and negative torque to one or more wheels of a vehicle to cause a vehicle to travel in accordance with a target speed value. The system receives information indicative of a gradient of a driving surface over which the vehicle is driving, with the torque control being configured to control the rate of change of the amount of torque applied to the one or more wheels in order to attempt to cause the vehicle to accelerate substantially from rest to a target speed value, the rate of change of the amount of torque being controlled by the torque control in dependence at least in part on the received information indicative of the gradient of the driving surface.

    Abstract: Embodiments of the present invention provide a vehicle speed control system operable to cause a vehicle to operate in accordance with a target speed value by controlling an amount of brake torque applied by a braking system and an amount of drive torque applied by a powertrain to one or more wheels of the vehicle, the system being operable to detect a leading wheel step event in which a leading wheel encounters an abrupt increase in surface gradient, the system being operable in dependence on the detection of a leading wheel step event to cause brake torque to be applied against drive torque in anticipation of a trailing wheel step event corresponding to the leading wheel step event, the system being operable to cause the application of brake torque at least until a trailing wheel has travelled a sufficient distance to reach the location at which a leading wheel experienced the leading wheel step event.

    Abstract: A method of operating an automatic speed control system of a vehicle in accordance with a set-speed. The method comprises receiving electrical signal(s) representative of a vehicle occupant-initiated brake command to slow the vehicle to a stop, and in response, suspending automatic speed control in accordance with said set-speed and commanding the application of a retarding torque to one or more wheels of the vehicle to bring the vehicle to a stop, while maintaining the speed control system in an active state. The method further comprises receiving electrical signal(s) representative of a vehicle occupant-initiated brake release command, and in response, and while maintaining the speed control system in an active state, automatically commanding the generation of drive torque sufficient to propel the vehicle in an intended direction and automatically controlling the speed of the vehicle in accordance with said set-speed.

    Abstract: A speed control system for automatically controlling the speed of a vehicle in accordance with a target speed value. The speed control system carries out a method that includes: causing automatically a vehicle to travel at a required speed value at least in part by controlling an amount of torque applied to one or more wheels of a vehicle by a powertrain; causing automatically a change in the required speed value according to a predetermined speed profile thereby to cause a corresponding change in a measured instant speed of a vehicle; and determining automatically when a powertrain torque interruption occurs. The system is configured temporarily to cause a suspension of changes in required speed value according to the predetermined speed profile when it is determined that a powertrain torque interruption occurs.
