    摘要: A skid steer vehicle has sprung suspensions, variable displacement pumps and motors connected to those pumps that drive the wheels on the vehicle as well as an electronic controller that receives signals that indicate fore-and-aft acceleration of the skid steer vehicle. Based on these signals, the controller determines whether the forward acceleration exceeds a predetermined value and locks up the rear suspensions if that value is exceeded. It also determines whether the forward deceleration exceeds a predetermined value and locks up the front suspensions if that value is exceeded. The signals can be provided by an accelerometer, a satellite receiver, wheel/motor speed sensors, sensors in the pumps that signal the specific displacement of the pumps such as their swash plate positions, or memory locations that contain previously calculated specific displacement commands that are used to drive the pumps to a particular specific displacement.

    摘要: A control system for a machine is disclosed. The control system may have a power source, an operator input device configured to generate a first signal indicative of a desired mode of power source operation, and a work implement driven by the power source. The control system may also have a controller in communication with the power source and the operator input device. The controller may be configured to classify a currently performed work implement task and select an output map based on the classification of the currently performed work implement task and the first signal. The controller may further be configured to control the power source operation using the output map.
