VEHICULAR TRACK MEASURING APPARATUS

摘要

Apparatus for measuring a track of a vehicle running on a test course, having: means for generating a voltage proportional to a distance along the longitudinal axis of the course between a track measurement starting plane on the course and the vehicle by generating standing radio waves above the course and counting the number thereof; and means for generating a voltage proportional to an angle contained by a reference vertical plane with respect to the course and another vertical plane with respect to the course intersecting the reference vertical plane and the vehicle by scanning the course rotatively with a laser beam from the line of intersection of these two vertical planes and measuring the time required for scanning the angle.
