摘要： 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 (1), comprises a sensing system (20, 21) for sensing the positions of roadway edges (5), a memory (24) that stores data relating to the width, and optionally lane width, of different types of road (4) on which the vehicle (1) may travel, and a data processor means (2) linked (26, 29) to the sensing system (20, 21) and memory (24). The processor means (2) compares the sensed positions of roadway edges (5) with the road width data in order to deduce the type of road (4) on which the vehicle (1) travels, and optionally also the lane in which the vehicle travels. The system may also include a vehicle speed sensor (13, 15) linked (33, 35) to the data processor means (2). The memory (24) then stores road speed data relating to different type of road (4) on which the vehicle (1) may travel, so that the processor means (2) can compare also the sensed vehicle speed with the road speed data in order to help deduce the type of road (4) on which the vehicle (1) travels.

摘要： A method and an apparatus for aligning the elevation of an automotive radar unit. The method of aligning a radar transceiver unit (4) on a vehicle (1) having the steps of: positioning at least three radar reflectors (7, 8, 9) in a pattern in which the reflectors are fixed relative to one another with the reflectors occupying three rows (20, 21, 22) at different elevations and at least three different horizontal positions (23, 24, 25), so that the middle row (21) is horizontally distinguishable from the neighboring rows (20, 22); directing a beam (14) of radar waves (12) from the radar transceiver (4) generally towards the radar reflectors (7, 8, 9); scanning (18), and if necessary repeatedly scanning, the beam (14) relative to the pattern so that the beam moves across the pattern at one or more fixed elevations in a horizontal direction; receiving at the radar transceiver (4) radar waves reflected (17) from one or more of the reflectors (7, 8, 9); detecting the elevation of the middle row (21); setting the elevation of the beam (14) of radar waves according to the detected elevation of the middle row (21).
