A Data Recording System of the Path of a Test Vehicle by Laser Beam and Some Applications to Steering Handling Test

Contact and collision accidents of automobiles are spatial, and measurements of the path and its dispersion of the automobile and evaluation of operating performance from these measurements are important. There is residual path measuring equipment but there is a demand for more modern equipment. The author has developed equipment to automatically measure the position of an automobile by triangulation using laser beams and to process the data using a computer. This article will explain this equipment and give the results of some experiments in which this equipment was used to test automobile control as application examples.
