| 摘要 |
The invention relates to a measuring system for measuring wheel angles and projected width of a vehicle (1) having at least two wheel pairs and a connection, such as a vehicle frame (4), between the respective wheel pairs, and that each wheel (5) of each wheel pair has a side facing away from the vehicle (1) and a rotational axis for each wheel (5). The measurement system comprises at least two measuring units (9, 10), each comprising a means (11), arranged to detect the orientation of the wheel side in space through repeated determination of the distance between the measurement unit (9, 10) and at least one point on the rotating wheel side of the wheels (5) of the vehicle (1), which rool on a substrate (U) when the vehicle (1) travels in a certain direction (F) between the measuring units (9, 10), and a processor (15), which, based on the reflected measurement signals (12) calculates the direction of the rotational axis of each wheel (5), the distance of each wheel (5) to the respective measurement unit (9, 10), the distance between each wheel (5) on each side of the vehicle (1) and the longitudinal geometric center line [C] of the vehicle (1). |
