A braking control system for an automotive vehicle having driven rear wheels which are coupled through a coupling arrangement to the front wheels of the vehicle so as to switch the vehicle between two-wheel drive mode and four-wheel drive mode, comprises an input for receiving a signal indicative of the nature of the terrain on which the vehicle is parked, wherein the nature of the terrain includes the incline of the terrain and one or more additional indicators of the nature of the terrain, and a processor configured to determine, depending on the signal, a braking force to be applied to the front wheels to brake the vehicle securely. The braking system comprises an output for providing a signal to the coupling arrangement to apply the determined braking force to the front wheels. The processor is also configured to receive a further signal indicative of whether the park brake of the vehicle is applied to the rear vehicle wheels, and is configured to disable the output in the event that the park brake is not applied.

Braking control system

Some embodiments of the present invention provide a control system configured to control a driveline of a motor vehicle to operate in a selected one of a plurality of configurations, the system being configured to receive a signal indicative of a location of the vehicle, the system being configured to cause the driveline to operate in a configuration selected in dependence at least in part on the signal indicative of the location of the vehicle.

Control system and method of controlling a driveline

Some embodiments of the present invention provide a control system configured to control a driveline of a motor vehicle to operate in a selected one of a plurality of configurations, the system being configured to cause the driveline to operate in a first configuration and not a second configuration in dependence on a first set of one or more conditions, the system being further configured to override operation in the first configuration and cause the driveline to operate in the second configuration and not the first configuration in dependence on the first set of one or more conditions and in addition a second set of one or more conditions.

Aspects of the present invention relates to a vehicle control system () for controlling a vehicle transfer case (). The transfer case () is operable in a high range and a low range. The vehicle control system () is configured to output a range change signal to implement a transfer case range change. The vehicle control system () also outputs a brake control signal for controlling vehicle braking during the range change. The present invention also relates to a vehicle () and a related method of operating a vehicle control system () and optionally also a transmission ().

Vehicle control system and method

Some embodiments of the present invention provide a control system configured to control a driveline of a motor vehicle to operate in a selected one of a plurality of configurations, the system comprising at least one sensor for sensing an environment ahead of the vehicle and generating a sensor signal in dependence on the environment, the system being configured to cause the driveline to operate in a configuration selected in dependence at least in part on the sensor signal.

Aspects of the present invention relate to a vehicle control system () for controlling a vehicle transfer case (). The transfer case () is operable in a high range and a low range. The vehicle control system () is configured to determine an operating range for the transfer case () based on a selected vehicle operating mode. A range change signal is output to implement a range change to engage the determined operating range. The present invention also relates to a vehicle () and a related method of operating a vehicle control system ().

Aspects of the present invention relates to a vehicle control system () for controlling a vehicle transfer case (). The transfer case () is operable in a high range and a low range. The vehicle control system () includes a selection means () for selecting first and second control strategies for the transfer case. The first and second control strategies are based on an activation time of the selection means (). A further aspect of the present invention relates to a vehicle control system () for implementing a deferred transfer case range change. The present invention also relates to a vehicle () and a related method of operating a vehicle control system ().
