A motor vehicle control system and a method of controlling a motor vehicle

摘要

A motor vehicle control system 10 and a method of controlling a motor vehicle 100 are provided. The motor control system 10 selects determines a driving surface and controls a plurality of vehicle subsystems 12a, 12b, 12c, 12d, 12e to operate in a plurality of subsystem control modes in dependence on the selected/determined driving surface. The system 10 is operable in a manual control mode selection condition in which a user is able to select the driving surface and an automatic control mode selection condition 20 in which the system is configured to select the driving surface automatically. The vehicle control system 10 is provided with a memory arranged to memorise a last selected control mode that was selected prior to vehicle deactivation or key-off when operating in the automatic control mode selection condition 20. Upon the next subsequent vehicle activation or key-on, the system is configured to continue operating in the memorised control mode and to automatically obtain new data in respect of a driving surface over which the vehicle is moving before allowing a change in control mode to take place.
