"Control system for controlling the speed of a motor direction in response to manipulation of a component input direction in a crawler vehicle hired.A crawler vehicle includes a steering pump of variable displacement driven by engine that drives a hydraulic motor direction.The steering motor drives a drive mechanism that drives the wheels differential drive (left and right.A control system for sensorea direction position of a steering wheel not centered by spring, vehicle speed, engine speed, the engine speed direction.Whether or not the transmission is in gear or in neutral, and the clutch is engaged or disengaged.To prevent a situation of cute self perpetuates the control system gradually reduces the speed of the motor direction if the transmission is in neutral or if the clutch is not engaged,And if the speed of the motor direction divided by the speed of the vehicle is greater than a threshold value, and if the vehicle speed is lower than a reference level.
