  • Patent number: 8972149
    Abstract: A control system for a machine is disclosed. The control system may have an engine configured to combust a mixture of fuel and air and generate a mechanical power output and a flow of exhaust, and a sensor configured to generate a signal indicative of the machine moving between zones having different air characteristics. The control system may also have a controller in communication with the engine and the sensor. The controller may be configured to selectively adjust operation of the engine based on the signal in an amount related to the air characteristics.
    Type: Grant
    Filed: October 27, 2010
    Date of Patent: March 3, 2015
    Assignee: Caterpillar Inc.
    Inventors: Robert A. Herold, Chad A. Moore, James V. Dornberger
  • Patent number: 8401753
    Abstract: A method for automatically controlling the downhill speed of a machine. The method includes establishing a target machine speed based on a current machine speed and determining whether at least one trigger condition including a grade greater than a predetermined threshold has been satisfied. If satisfied, the method activates a control system to control at least one of a powertrain retarder and a change in a transmission gear to prevent exceeding the target machine speed.

  • Publication number: 20030123724
    Abstract: A method is provided for colorizing an electronic schematic including a set of features, wherein each feature includes one or more elements. First, a set of features to be colorized on the schematic is identified. A color scheme is established that includes a color associated with each of the features. An element is associated with one of the features. The element is then automatically colorized based on the color scheme.
