Abstract
The present invention relates to measurement of the trajectory of a motor vehicle with respect to a roadway. A trajectory measurement system for a motor vehicle ( ), comprises a sensing system ( ) for sensing the positions of roadway edges ( ), a memory ( ) that stores data relating to the width, and optionally lane width, of different types of road ( ) on which the vehicle ( ) may travel, and a data processor means ( ) linked ( ) to the sensing system ( ) and memory ( ). The processor means ( ) compares the sensed positions of roadway edges ( ) with the road width data in order to deduce the type of road ( ) on which the vehicle ( ) travels, and optionally also the lane in which the vehicle travels. The system may also include a vehicle speed sensor ( ) linked ( ) to the data processor means ( ). The memory ( ) then stores road speed data relating to different type of road ( ) on which the vehicle ( ) may travel, so that the processor means ( ) can compare also the sensed vehicle speed with the road speed data in order to help deduce the type of road ( ) on which the vehicle ( ) travels.
