摘要： A hydraulic system for a mobile machine is disclosed. The hydraulic system may have a first actuator, a first valve arrangement, a second actuator, and a second valve arrangement. The hydraulic system may also have at least one operator interface device movable by an operator to generate a first signal indicative of desired work tool movement in a first manner, and a second signal indicative of desired work tool movement in a second manner; and a controller configured to generate a first flow rate command directed to the first valve arrangement based on the first signal, and generate a second flow rate command directed to the second valve arrangement based on the second signal. The controller may also be configured to selectively generate a third flow rate scaled from the first flow rate command and directed to the second valve arrangement based on only the first signal.

摘要： A hydraulic system is disclosed. The hydraulic system may have a pump, a lift actuator, a lift valve arrangement, a tilt actuator, a tilt valve arrangement, and a tilt angle sensor configured to generate a first signal. The hydraulic system may further have at least one operator interface device movable to generate a second signal indicative of a desired lift velocity and a third signal indicative of desired tilt velocity, and a controller. The controller may be configured to command the lift valve arrangement to meter pressurized fluid based on the second signal, command the tilt valve arrangement to meter pressurized fluid based on the third signal and, when the first signal indicates that the actual tilt angle has entered a specified range of tilt angles during lifting, command the tilt valve arrangement to meter pressurized fluid based on the second signal as the actual tilt angle remains within the specified range.

摘要： A machine includes a drive train with an electronically controlled transmission in communication with an electronic engine controller. The machine ground speed is limited by executing a vehicle speed limit algorithm in the electronic transmission controller. This algorithm generates an engine control message that is communicated to the electronic engine controller. The power output of the engine is reduced responsive to the engine control message. The machine responds by not exceeding a prescribed speed limit programmed into the electronic transmission controller. This vehicle speed limiting strategy is particularly applicable to machines without a vehicle speed limiting algorithm resident in the electronic engine controller.

摘要： An apparatus for measuring the distance to a reflective surface. A first light source transmits a first light onto the reflective surface, the first light source being located on a first side of an axis. The reflective surface reflects at least a portion of the light onto a first light-detecting device having a first region operable to receive the reflected first light from the reflective surface. The first light-detecting device transmits a first and second signals as a function of the location of the received first light within the first region. A second light source transmits a second light onto the reflective surface, the second light source being located on a second side of the axis. The reflective surface reflects at least a portion of the second light onto a second light-detecting device having a second region operable to receive the reflected second light from the reflective surface. The second light-detecting device transmits a third and fourth signals as a function of the location of the received light within the second region. A processing device is coupled with the first and second light-detecting devices to respectively receive the first, second, third, and fourth signals. The processing device transmits a position signal indicative of the distance to the reflected surface as a function of the first, second, third, and fourth signals.
