An apparatus for detecting the distance between one\s car and the car ahead, together with the angle between the axes of the two cars. The apparatus has a pair of driving optical systems disposed at a predetermined distance from each other, each driving optical system comprising an optical system having a light projector which projects pulse light having a specific code toward the car which is ahead of the one\s car and a light receiver which receives the reflected pulse light from the car ahead, the light projector and receiver being disposed in so close proximity to each other that the respective optical axes can be considered to be on substantially the same axis, and a driving system for adjusting the angle of projection of the light projector on the basis of a signal from the light receiver. The apparatus further has a central processing unit which measures the angle of projection of the pulse light from the light projector when the light receiver of each of the driving optical systems detects the reflected pulse light, thereby detecting the distance between the one\s car and the car ahead, together with the angle between the axes of the two cars.

An apparatus for detecting the distance between one\s car and a car ahead, comprising: a pair of driving optical systems provided on the one\s car at a predetermined distance from each other, each driving optical system comprising an optical system having a light projector which projects pulse light having a specific code toward the car which is ahead of the one\s car and a light receiver which receives reflected pulse light from said car ahead, said light projector and receiver being disposed in such a close proximity to each other that their respective optical axes can be considered to be on substantially the same axis, and a driving system for rotatably adjusting an angle of projection of said light projector on the basis of a signal from said light receiver; and a central processing unit provided on the one\s car to measure the angle of projection of said pulse light from each light projector when said light receiver of each of said driving optical systems detects said reflected pulse light, thereby detecting the distance between said one\s car and said car ahead, together with an angle between longitudinal axes of said two cars.
