OBSTACLE DETECTOR FOR AUTOMOBILE

摘要

PURPOSE:To properly forecast an advancing route and to efficiently detect an obstacle by limiting the area of detection of an obstacle by a rader device only in an area along the advancing route of his own vehicle. CONSTITUTION:This obstacle detector is provided with a rader device 4 for radiating rader waves to the front of his own-vehicle to detect an obstacle existing in the front, a steering angle sensor 5 for detecting the steering angle of his own vehicle and a yaw rate sensor 7 for detecting a yaw rate. A 1st advancing route forecasting means 8 forecasts the advancing route of his own vehicle based upon the steering angle and a 2nd advancing route forecasting means 9 forecasts the advancing routes of his own vehicle based upon the yaw rate. A selection means 10 selects either one of two advancing routes in accordance with the operation state of his own vehicle and the device 4 detects an obstacle by limiting its detection only to an area along the selected advancing route.
