Abstract
A vehicle is adapted to sense a condition of use in which a maximum speed control speed is reduced. The condition of use may be indicated by a sensor of the vehicle, or selected according to the kind of terrain across which the vehicle is travelling. Selection of terrain type may be manual or automatic, and may enable a selection of sensors appropriate to the terrain type. A vehicle driver may select a speed control speed lower than the permitted maximum.
Claims19
A method of automatically controlling the speed of a vehicle to maintain a speed control speed, said method comprising:
- detecting a plurality of off-road conditions of the vehicle;
- and
- determining a maximum speed control speed appropriate to each of the detected off-road conditions;
- and
- automatically setting a maximum speed control speed appropriate to the detected off-road condition corresponding to the minimum determined maximum speed control speed.
An electronic control unit for automatically controlling the speed of a vehicle to maintain a speed control speed, the electronic controller adapted to detect a plurality of off-road conditions of the vehicle, calculate a maximum speed control speed appropriate to each of the detected off-road conditions, and set a maximum speed control speed appropriate to said condition corresponding to the minimum calculated maximum speed control speed.
