Title: Distance measuring instrument for vehicle
Inventor: SUGINO TAKASHI
IPC: G01B11/00
Filed: 2001-07-31
Abstract: PROBLEM TO BE SOLVED: To recognize reflected light from a road surface discriminatingly from reflected light from a vehicle. SOLUTION: The laser light 4 emitted by a laser radar 3 mounted on the vehicle 1 is reflected by an object to be detected such as a precedent vehicle 2, a road surface 5, and a splash 6 to return. The laser radar 3 receives the reflected laser light 4 and generates measurement data (distance, direction, quantity of received light, etc.), according to the quantity of the received light. When the object to be detected is present within a specific distance range wherein road surface reflection is possibly caused, the laser radar 3 judges whether the object to be detected is the road surface 5, and adds a road surface flag when judging the road surface 5 to exclude it from an object of precedent vehicle recognition processing for the precedent vehicle 2 to be performed next.  Consequently, the reflected light from the road surface 5 can be recognized discriminatingly from the reflected light from the vehicle.
