OBSTACLE DETECTING/ALARMING SYSTEM FOR VEHICLE

摘要

An obstacle detecting/alarming system for vehicles comprising at least one obstacle sensor being fixed to the front or rear end of a vehicle, and means for informing an alarm message indicative of the expected effect of a trouble detected by the obstacle sensor on a vehicle. A decision criterion setting means in the inventive system determines a traveling track of the vehicle by analyzing the traveling direction and the steering angle thereof and provides a decision criterion unique to the track of vehicle thus determined and variable depending on the steering angle. Based on this decision criterion, the driver is provided with an alarm message indicative of whether the vehicle has a possibility of touching an obstacle detected by means of the obstacle sensor or not. Conditions for detecting an obstacle can be varied depending on the traveling track of the vehicle and an accurate decision results of obstacle can be imparted to the driver by detecting only an obstacle in the vicinity of the actual course of the vehicle.
