Abstract: Embodiments of the present invention provide a system comprising: a first controller configured in each of a predetermined plurality of states to generate a torque request signal in order to cause a vehicle to operate in accordance with a target speed value, the system being configured, when the first controller is one of said plurality of states to generate a gear shift limit signal to cause a change in an engine speed at which a transmission controller is permitted to cause a gear downshift, the gear shift limit signal being generated in dependence on at least one traction indicator signal indicative of an amount of estimated traction between the vehicle and a driving surface.

Abstract: Embodiments of the present invention provided a system comprising: a plurality of speed controllers each configured to assume one or more ‘on’ states or one or more ‘off’ states, in a predetermined one or more on states each speed controller being configured to cause a vehicle to operate in accordance with a target speed value, in an off state each speed controller being configured not to cause a vehicle to operate in accordance with a target speed value, the system being configured wherein only one of the speed controllers may be in an on state at a given moment in time, the other one or more speed controllers being arranged to assume an off state when a speed controller is in an on state, the system being configured to delete from a speed controller memory or associated speed controller memory directly accessible by said speed controller, one or more target speed values employed by a speed controller that is not in an on state.

Abstract: Embodiments of the present invention provide a system comprising: a first controller operable to assume one of a plurality of respective states, in a first state the first controller being configured automatically to cause a powertrain to develop drive torque and cause a vehicle to operate in accordance with a target speed value, the first controller being configured to receive a door state indicator signal indicative of whether a door is in an open or closed state, and an occupant presence indicator signal indicative of whether an occupant is present in a given seat of a vehicle, the system being configured not to permit operation of the first controller in the first state in dependence on the door state indicator signal and the occupant presence indicator signal.

Abstract: A system comprising a speed controller configured to generate a speed controller powertrain signal in order to cause a powertrain to develop drive torque and cause a vehicle to operate in accordance with a target speed value. The system generates a signal indicative of a rate of acceleration of the vehicle, and is configured to command a powertrain to develop an amount of positive drive torque according to the speed controller powertrain signal in dependence at least in part on the signal indicative of the rate of acceleration of the vehicle.

Abstract: Aspects of the disclosure relate to a method of controlling an HMI-apparatus for providing information to a driver of a vehicle for aiding driver control of a vehicle when the vehicle is wading in a body of water. The method includes determining a measured depth of water about the actual vehicle and determining a display depth, dependent upon the measured depth of water. The method also includes measuring a lateral and/or longitudinal gradient of the actual vehicle and selecting a display vehicle position from a limited number of available options of display vehicle positions based upon the measured lateral and/or longitudinal gradient of the actual vehicle. In this way the HMI-apparatus can output a simplified picture of the actual vehicle scenario which may be easier for the driver to assimilate.

Abstract: A vehicle comprises a system for aiding driver control of the vehicle when the vehicle is wading in a body of water, the system comprising a measurement apparatus for determining a measured depth of water in which the vehicle is wading. The measurement apparatus is positioned and arranged relative to the vehicle such that the measured depth is indicative of the depth of water in a first measurement region relative to the actual vehicle. The processor is coupled to the measurement apparatus and is configured to calculate an estimated water depth in dependence upon the measured depth and in dependence upon the vehicle speed.

Abstract: A method of controlling an HMI-apparatus for providing information comprising comparing data from two or more remote-ranging sensors disposed at an elevation greater than the threshold wading depth of the vehicle.

Abstract: Embodiments of the present invention provide a motor vehicle control system comprising: a first user-operable transmission selector means for selecting a transmission operating mode; and a second user-operable transmission selector means for selecting a transmission operating mode, wherein the first transmission selector means and not the second transmission selector means is operable to select a transmission operating mode when the control system is operated in a first predetermined function mode and the second transmission selector means is operable to select a transmission operating mode when the control system is operated in a second predetermined function mode different from the first, the control system being configured to assume operation in the second predetermined function mode when a first set of one or more predetermined conditions are met.

Abstract: Some embodiments of the present invention provide a control system for a motor vehicle having a first user-operable transmission selector means for selecting a forward operating mode of a transmission corresponding to travel in a forward direction and a reverse operating mode of a transmission corresponding to travel in a reverse direction opposite the forward direction, the control system comprising: a user-operable gear selector configured in a first functional mode to, upon receipt of a user input, select between a plurality of forward direction gear ratios, and wherein the user-operable gear selector is re-configured in a second functional mode to, upon receipt of a user input, select between the forward operating mode and the reverse operating mode.
