    摘要: A retarding system for a work machine is disclosed. The retarding system has a power source, a transmission, and a torque converter operatively coupling the power source and the transmission. The torque converter has a lockup clutch. The retarding system also has a controller in communication with the lockup clutch. The torque converter is configured to receive an input indicative of a desired work machine acceleration, to determine a status of the lockup clutch, and to determine if engaging the lockup clutch will cause a speed of the power source to drop below a low idle speed. The controller is also configured to engage the lockup clutch if the input indicates that the desired work machine acceleration is below a predetermined amount, the lockup clutch is disengaged, and the speed of the power source will remain above the low idle speed after engagement of the lockup clutch.

    摘要: A method of controlling driveshaft speed includes generating an overspeed protection action signal if an engine speed limit and a requested transmission gear ratio correspond to a driveshaft overspeed condition. An operating method for a machine includes disengaging a relatively higher transmission gear, and inhibiting re-engagement of the higher transmission gear responsive to an overspeed protection action signal. An electronic controller for the machine is configured to generate an overspeed protection action signal responsive to an engine speed limit and requested transmission gear ratio.

    摘要: Apparatuses and methods for processing a signal in a moveable vehicle having an engine. A first combustion governor receives a first control signal and transmits a first governor signal operable to control an engine speed of the engine as a function of the first control signal. A second combustion governor receives the first control signal and to transmits a second governor signal operable to control an engine power production of the engine as a function of the first control signal. A first sensor determines a first characteristic of the vehicle transmits a first selecting signal as a function of the first characteristic. A governor-selecting device is coupled with the sensor to receive the first selecting signal. The governor-selecting device performs at least one of the following: receives the first control signal and transmits the first control signal to one of the first and second combustion governors as a function of the first selecting signal; and is coupled with at least one of the first and second governors to receive at least one of the first and second governor signals, and transmits one of the first and second governor signals as a function of the first selecting signal.

    摘要: A method of controlling an automatic transmission of a machine includes a step of identifying an upcoming gear ratio change from a current gear ratio to a proposed gear ratio. An estimated power output value, based on the proposed gear ratio and a current engine speed, is determined. The estimated power output value is adjusted based on a derated operating condition. If the estimated power output value is greater than or equal to a current power output value, a gear evaluation identifier is set to a first value. If the estimated power output value is less than the current power output value, the gear evaluation identifier is set to a second value.

    摘要: A power system includes an engine that has engine controls, a power load, and a torque converter connected between the engine and the power load. The engine controls may operate the engine according to a first control strategy in at least some circumstances. The first control strategy may provide higher engine fuel efficiency at a first combination of engine speed and torque that corresponds to a drive speed/reaction torque band of the torque converter than it provides at combinations of engine speed and torque that do not correspond to the drive speed/reaction torque band of the torque converter. Additionally, at one or more combinations of engine speed and torque other than the first combination, the first control strategy may cause the engine to produce a lower quantity of at least one noxious exhaust emission than the engine produces at the first combination of engine speed and torque when operated according to the first control strategy.

The control inputs signals produced by the sensor and responsively calculates a plurality of rating factors. The control weights the rating factors according to owner programmed weighting and also calculates a driver performance factor as the sum of the weighted rating factors. A modified vehicle speed limit is calculated in response to the driver performance score exceeding a minimum incentive value.

    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.
