Title:
OBSTACLE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/025512
Kind Code:
A1
Abstract:
An obstacle determination unit (221) determines that a detected object is an obstacle when the object detected by a distance sensor (40) is located in a monitoring region that is set in a blind spot of an operator. In addition, the obstacle determination unit (221) sets the monitoring region so that a region showing a lower traveling body (2) is excluded in accordance with the turning angle detected by an angle sensor (210). A stop control unit (222) determines, on the basis of the turning angle detected by the angle sensor (210), whether a component, that is, the lower traveling body (2) and/or an upper turning body (3), of construction machinery (1) may collide with an obstacle when the component is operated, and stops operation of the component that is determined to be likely to collide.
