WORK MACHINE AND METHOD FOR BRAKING WORK MACHINE

By | October 5, 2018

Provided is a technique for efficiently operating a control system and operation system brakes in an autonomous driving vehicle according to the operating conditions of the autonomous driving vehicle. The present invention is provided with: a high-pressure selection valve on a flow passage that supplies hydraulic pressure to a hydraulic brake device from a standard brake valve mounted in a standard machine; and a flow passage that connects an autonomous brake control valve, to which the hydraulic pressure discharged from a hydraulic pump is supplied, and the high-pressure selection valve. In addition, the present invention is provided with: an autonomous driving control device that performs controlling for allowing autonomous driving; and an autonomous brake control device that controls the autonomous brake control valve to be opened/closed in response to a brake command from the autonomous driving control device. When a brake pedal is depressed, a hydraulic oil flows from the standard brake valve to the hydraulic brake device; and when the autonomous driving control device outputs a stop command, the hydraulic oil flows from the autonomous brake control valve to the hydraulic brake device, and a braking operation is thereby performed.
