CONTROLLING METHOD OF CONSTRUCTION MACHINARY

摘要

An embodiment of the present invention relates to a method for controlling a function of a construction machine, and a vehicle mode change signal input step of inputting a signal for using a vehicle as an emergency vehicle for disaster relief, and an emergency mode in the vehicle mode change signal input step When the exhaust gas treatment device is judged to be in a fault condition of determining whether the vehicle's exhaust gas treatment device is malfunctioning, and if the vehicle's exhaust gas treatment device is judged to be faulty in the exhaust gas treatment device's failure judgment step, a predetermined time is set to exhaust. The function release time setting step for releasing the gas processing device failure detection function, the set time determination step for determining whether the time set for function release in the function release time setting step has been exceeded, and the time set in the set time determination step If it is judged that it has not been exceeded, the exhaust gas treatment failure detection function is maintained. And, when it is determined that the set time exceeds, the exhaust gas treatment device failure detection function recovery step of restoring the winding function.
