Abstract:
A system and a method for operating a hydraulic driven work machine including a hydraulic travel motor having a variable displacement is provided, wherein a flow of hydraulic fluid generated by a hydraulic pump is provided to the travel motor and wherein a control valve is provided for controlling the flow of hydraulic fluid from the hydraulic pump to the travel motor. The hydraulic pump is provided with a hydraulic control depending on a load signal generated by the travel control valve and the travel motor is provided with an electric control according to a desired driving behavior.
