<p>A system for use in a vehicle 10 determining the type of terrain 24 ahead of the vehicle is provided. The system comprises; a processor configured to receive sensor output data from a plurality of vehicle-mounted sensors 12, 22, including at least one radar sensor 22 and at least one acoustic sensor 12, each for receiving a reflected signal 20 from the terrain 24 ahead of the vehicle 10; and a data memory configured to store pre-determined data relating sensor output data, for the or each acoustic sensor 12 and the or each radar sensor 22, to a terrain type. The processor is configured to compare the sensor output data with the pre-determined data to determine an indication of the terrain type corresponding to the sensor output data.</p> |
