  • Patent number: 9587571
    Abstract: A control apparatus for an internal combustion engine comprises a throttle upstream pressure estimation unit which calculates, based on an AFS intake air amount from an AFS and an intake manifold pressure, an average density ?ave(n) in a region combining a supercharged portion from a downstream of a compressor to an upstream of a throttle valve and an intake manifold, and estimates a throttle upstream pressure based on the intake manifold pressure and the average density ?ave(n). Further, the throttle upstream pressure estimation unit learns a relationship between a throttle opening degree and an effective opening area to correct a throttle upstream pressure estimated value (estimated P2) based on a range of a throttle opening degree learning value, the throttle opening degree learning value, and a dispersion of the actual throttle opening degree error.

  • Patent number: 9581998
    Abstract: In a system and method for communicating data in a locomotive consist or other vehicle consist (comprising at least first and second linked vehicles), a first electronic component in the first vehicle of the vehicle consist is monitored to determine if the component is in (or enters) a failure state. In the failure state, the first electronic component is unable to perform a designated function. Upon determining the failure state, data is transmitted from the first vehicle to a second electronic component on the second vehicle, over a communication channel linking the first vehicle and the second vehicle. The second electronic component is operated based on the transmitted data, with the second electronic component performing the designated function that the first electronic component is unable to perform.

  • Patent number: 9546605
    Abstract: The present invention addresses a solution of improving precision with which requested torque at a time of a transient operation is realized in a control device for an internal combustion engine that controls torque that is generated by an internal combustion engine by control of an air amount by means of a throttle. To this end, the present control device calculates a target intake pipe pressure for realizing a target air amount, and calculates predicted pump loss from the target intake pipe pressure. By adding the predicted pump loss to requested torque to the internal combustion engine, 360° indicated requested torque that should be realized in a compression/expansion strokes is calculated. An air amount for realizing the 360° indicated requested torque is calculated as the target air amount, and an opening of the throttle is determined based on the target air amount.

  • Patent number: 9517772
    Abstract: A drivetrain system for a machine includes an engine, a brake, and a controller operatively coupled to the engine and the brake. The controller is configured to generate a first speed error based on a first speed command signal and a first ground speed signal; generate a first engine speed command signal based on the first speed error; send the first engine speed command signal to the engine; compare the first speed error to an upper threshold; set a brake command signal to an engagement value when a magnitude of the first speed error is greater than a magnitude of the upper threshold; engage the brake in response to setting the brake command signal to the engagement value; and increase a speed of the engine in response to the first engine speed command signal while the brake command signal is set to the engagement value.

  • Patent number: 9440603
    Abstract: A vehicle control system is provided that is able to (i) identify a particular driver from other potential drivers and (ii) monitor various vehicle functions in order to determine if the identified driver repeatedly performs the same behavior when the vehicle is at or near the same location. When the control system determines that the identified driver repeats the same behavior in response to the vehicle being at or near the same location, the controller learns that behavior and associates it with the identified driver so that it can be automatically performed, without driver interaction, when the vehicle is at or near the same location in the future.
