REMOTE CONTROL CONSOLE FOR A MACHINE

Abstract:

A remote control console or operator's station includes a proportional travel control joystick that effects continuous changes in machine travel speed through movement of the joystick away from a central-biased position, a sensor that measures progressively changing positions of the joystick, and an electronic controller communicatively coupled to the sensor and the joystick. The electronic controller is programmed to perform a closed loop control including mapping the progressively changing positions of the joystick to corresponding desired machine travel speeds, and adjusting the speeds of an engine used to propel the machine and the amounts of service braking used to slow the machine to achieve desired machine travel speeds.
