CONSTRUCTION MACHINE TRAVELING CONTROL SYSTEM
The present invention relates to a construction machine traveling control system and, more particularly, to a construction machine traveling control system capable of switching to various traveling patterns desired by the driver easily and quickly in connection with a construction machine equipped with electric traveling pedals, such as an excavator. To this end, the present invention provides a construction machine traveling control system comprising: first and second electric traveling pedals for outputting manipulation values comprising electric signals in response to the driver's manipulation and thereby operating first and second traveling motors connected thereto, respectively; a traveling pattern input means installed in the driving room so as to enable the driver to input a construction machine traveling pattern; a controller electrically connected to the first and second electric traveling pedals and to the traveling pattern input means so as to sense the manipulation values output from at least one of the first and second electric traveling pedals and the traveling pattern input to the traveling pattern input means and to calculate and output command values required for operations of the first and second traveling motors according to the inputted traveling pattern; and a hydraulic circuit electrically connected to the controller so as to control the flow rate of operation oil supplied to the first and second traveling motors, as well as the flow of the operation oil, according to the command values delivered from the controller, thereby driving the first and second traveling motors.
