Abstract: A steerable, self-propelled vehicle includes a rotatable steering column that is connected to control the steering angle of one or more ground-engaging members of the vehicle. The vehicle includes between the steering column and the ground-engaging member a first steering servomechanism having at least a first steering assistance characteristic; a second steering servomechanism having a second steering assistance characteristic also being connected to act on the steering column. A controller is provided for causing the first and second steering assistance characteristics to influence the steering of the vehicle in dependence on one or more one or more control commands generated in the controller.

Abstract: A method of controlling the braking of a tractor-trailer combination (10) in which the tractor (11) includes a drive train having an engine and at least one ground-engaging member (14, 16) driveably connected thereto via an adjustable-ratio transmission; at least one ground-engaging member (14, 16) of the tractor includes at least one tractor brake; and at least one ground-engaging member (17) of the trailer (12) includes at least one further, trailer brake, comprises the steps of determining (i) the deceleration of the tractor-trailer combination (10) resulting from braking effort applied via the tractor brake and/or (ii) the deceleration of the tractor-trailer combination resulting from engine braking. The method also includes establishing from one or both the said, determined decelerations as a target value in a control system a braking effort of the trailer brake that approximates the braking of the tractor-trailer combination (10) to the braking of the tractor (11) when considered alone.

Abstract: A vehicle including a respective brake for each driven, ground-engaging member that is operable under the control of driven member brake commands generated in a controller, a ground-engaging, steerable member that defines a steering angle, a sensor for generating a steering angle signal that is indicative of the steering angle, a sensor for generating a vehicle speed signal, and a sensor for generating a respective driven member speed signal. The controller is capable of generating driven member brake commands based on steering angle and vehicle speed signals together with a driven member slip estimation signal that is generated from the driven member speed signals.
