摘要

A system for use in a vehicle for determining an indication of the type of terrain in the vicinity of the vehicle, the system comprising; means configured to receive sensor output data from at least one vehicle-mounted sensor (12, 22) which is configured to receive a reflected signal from the terrain; means configured to calculate at least two parameters from the sensor output data; means configured to convert the at least two parameters to a data point for a cluster model comprising a plurality of clusters of pre-determined data points, wherein each cluster corresponds to a different terrain type; and means configured to define to which one of the clusters the data point belongs, so as to determine an indication of the terrain type.
