A METHOD AND APPARATUS FOR SHOCK ABSORBING OF HEAVY EQUIPMENT IN URGENT RETURN

摘要

The present invention is to allow the forward and backward solenoid valve to be in a neutral state for a certain period of time in order to prevent the shock due to rapid deceleration and rapid acceleration generated when changing the forward and backward driving direction while pressing the running pedal The present invention relates to a control device and a control method for alleviating an impact when changing forward and backward rapid movement of heavy equipment. To this end, if the traveling direction of the vehicle is changed during driving, the driving speed at which the vehicle is not impacted by inertia is set as a reference value, and the change of the forward and backward selection means for selecting the forward, backward, and neutral of the vehicle may be performed. If it is present, the controller outputs an electrical signal to inform the controller of the change, and when the change signal is input to the controller, it drives the forward / backward solenoid valve to switch to a neutral state. If the current running speed value exceeds the reference value, the forward and backward solenoid valve continues to be neutral until the current running speed value reaches the reference value. State, while driving the solenoid valve forward and backward when the reference value is reached.
