Improvements in vehicle speed control

摘要

A slope detection system for a vehicle 100 is provided. The system has a processor (19 fig 3) that receives, from one or more sensors 185C arranged to capture data in respect of terrain ahead of the vehicle, terrain information indicative of the topography of an area extending ahead of the vehicle 100. The processor (10, 19), in dependence upon a predicted path of the vehicle over the terrain extending ahead of the vehicle (100), generates, for the predicted path of the vehicle 100, information indicative of an angle of slope of the predicted path, being the slope of the predicted path along a direction of travel of the vehicle 100. The information comprises or generates a 3D point cloud. The vehicle is preferably driven at a speed which takes account of the determined road slope.
