Title:
OBSTACLE DETECTING DEVICE FOR RUNNING VEHICLE
Document Type and Number:
Japanese Patent JPH01197148
Kind Code:
A
Abstract:
PURPOSE:To prevent erroneous detection of an obstacle by anticipating a running path of a vehicle running a narrow place in a plant in accordance with a steering angle, and by removing obstacle detecting sensors in detection areas out of the advancing direction of the vehicle, from those for obstacle detection. CONSTITUTION:Obstacle sensors 4-8 set for detection areas 14-18 are attached on the front section of a vehicle self-traveling on a predetermined running path such as a floor 10 or the like in accordance with a program. There are provided limit switches LS1-LS5 actuated by a striker 20 associated with a steering wheel 3, whose output signals are delivered to a selected circuit together with output signals from the obstacle detecting sensors 4-8. The sensors 4-8 are selectively actuated as follows. For example, if an LS3 is turned on during advance of the vehicle 1, sensors 5-7 are turned on excepting both end sensors 4, 8, and further if an LS5 is turned on during right turn, right side sensors 7, 8 are turned on.
