Abstract: Aspects of the present invention relate to an imaging system (1) for a towing vehicle (V1). The imaging system (1) includes a processor configured to determine a reference speed (Vref) of the towing vehicle (V1). First image data (D1) is received from a first imaging device (C1); and second image data (D2) is received from a second imaging device (C2). The first imaging device (C1) may be disposed on the towing vehicle (V1); and the second imaging device (C2) may be disposed on a towed vehicle (V2). A first scaling factor (SF1, SF2) is applied to the second image data (D2) to generate scaled second image data (D2). The first scaling factor (SF1, SF2) is determined in dependence on the determined reference speed (Vref) of the towing vehicle (V1). Composite image data (D3) is generated by combining at least a part of the scaled second image data (D2) with at least a part of the first image data (D1). The composite image data (D3) is output for display on a display screen (10).

Abstract: A controller for a vehicle is configured to determine the position of the accelerator pedal with respect to a reference accelerator pedal position (aref); and either determine a torque output in dependence on an acceleration pedal map if the position of the accelerator pedal is greater than the reference accelerator pedal position (aref); and, determine a torque output in dependence on a deceleration pedal map if the position of the accelerator pedal is less than the reference accelerator pedal position (aref).

Abstract: The present disclosure relates to a creep speed control system for a vehicle having at least one electric motor for providing torque to at least one vehicle wheel. The system comprises an input configured to receive a current speed signal indicative of a current speed of the vehicle; a creep speed control module that is configured to activate when the current speed of the vehicle crosses a predetermined threshold above a creep speed target value; and, an output configured to, upon activation of the creep speed control module, send a creep speed control torque signal to the at least one electric motor to control the vehicle speed in dependence on the creep speed target value, wherein the creep speed control torque signal is limited to a creep speed control filtered torque value less than a creep speed control maximum torque value.

Abstract: An apparatus for controlling movement of a vehicle includes processing means configured to: receive first signals from a receiving means in dependence on received transmitted signals from a remote control device indicating a requested motion of a vehicle; receive one or more second signals indicative of a diagnostic device being in operative communication with the vehicle; and provide an output signal for controlling movement of the vehicle in dependence on the requested motion. The output signal is inhibited if: a diagnostic device is in operative communication with the vehicle and a maintenance mode has not been activated, as determined from the first signals or from one or more third signals; or if a door or the bonnet is open, unless a diagnostic device is in operative communication with the vehicle; or if the vehicle weight is not being borne by the wheels unless a diagnostic device is in operative communication with the vehicle.

Abstract: The present disclosure relates to a controller for controlling operation of at least first and second traction machines in a vehicle. The controller includes a processor configured to predict an operating temperature of each of said at least first and second traction machines for at least a portion of a current route. The processor determines at least first and second torque requests for said at least first and second traction machines. The at least first and second torque requests are determined in dependence on the predicted operating temperatures of the at least first and second traction machines. The processor generates at least first and second traction motor control signals in dependence on the determined at least first and second torque requests. The present disclosure also relates to method of controlling at least first and second traction machines in a vehicle.

Abstract: An electromagnetic valve actuator and method of control thereof. The electromagnetic valve actuator is for at least one valve of an internal combustion engine, the electromagnetic valve actuator comprising: a rotor; a stator for rotating the rotor; output means for actuating the valve in dependence on rotation of the rotor; mechanical energy storage means arranged to store energy in dependence on rotation of the rotor and release the energy to assist rotation of the rotor and phase varying means for varying a phase between the mechanical energy storage means and the output means.

Abstract: Apparatus for controlling movement of a vehicle, a system and vehicle comprising the apparatus, and a method for controlling the movement of a vehicle are disclosed. The apparatus comprises a controller configured to receive first signals from a receiving means in dependence on received transmitted signals from a remote control device indicating a requested motion of a vehicle and to receive second signals indicative of a value of traction of the vehicle. A maximum speed value for the vehicle is determined in dependence on the value of traction of the vehicle and/or on one or both of the detected pitch and roll angles of the vehicle. The controller provides an output signal for controlling speed of the vehicle based on the requested motion. The output signal is limited dependent upon the maximum speed value determined by the controller.

Abstract: Aspects of the present invention relate to an active diffuser mechanism for a vehicle comprising a mounting mechanism for connecting a diffuser body to a body of a vehicle such that the diffuser body is moveable between a stowed position and a deployed position in which an airflow surface of the diffuser body is spaced further away from the body of the vehicle than in the stowed position. The mounting mechanism comprises a linkage mechanism configured such that the diffuser body follows a linear translation path and a rotational path during movement from the stowed position to the deployed position. Aspects of the present invention also related to an active diffuser assembly, an active diffuser system and a vehicle comprising such an active diffuser mechanism.
