Abstract

PURPOSE:To accurately detect a dangerous area in turning by calculating the dangerous area corresponding to a tire turning angle by an arithmetic processing means and judging by comparison whether or not an obstacle in the dangerous area from the output value of an obstacle detecting means. CONSTITUTION:Detection signals which are outputted by turning angle sensors 1 installed nearby both rear wheels of a fork lift corresponding to the turning angles of the tires are inputted to a CPU 4 through an A/D converter 3. Detection signals outputted by obstacle detection sensors 5 installed on both flanks of the fork lift corresponding to the distance to the obstacle are inputted to the CPU 4 through an A/D converter 6. Then the CPU 4 calculates the dangerous area from the detected value of the turning angles and also inputs the output values of the sensors 5 to judge whether or not the obstacle is in the dangerous area. Then control signals are outputted to a controller 8, and a drivers 9 and 11 according to processing to control a display device 10 and also control the operation of the warning device 12.
