Document Type and Number:
Japanese Patent JP3336207
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To early detect an obstacle such as a cut-in vehicle from an adjacent lane in high-speed traveling of a vehicle by forward increasing the warning generating range in relation to the obstacle with the increase of the vehicle speed of a driver's own vehicle, and increasing the lateral width with the transfer from the medium speed to the high speed. SOLUTION: A laser beam feeding and receiving part 3 forward radiates pulse-like laser beams from a light feeding part from a driver's own vehicle. The radiated laser beams are reflected by an obstacle such as a traveling vehicle existing ahead of the driver's own vehicle and received by a light receiving part of the laser beam feeding and receiving part 3. An obstacle detecting part 2 detects the distance to the obstacle such as the forward vehicle on the basis of the transmission time required from the time when the laser feeding and receiving part 3 feeds the light beams to the time when it receives the reflected. The direction (azimuth) of the obstacle as viewed from the driver's own vehicle as well as the distance from the driver's own vehicle to the obstacle are detected with lateral scanning of the radiation laser beams.
