Christopher Michael James Douglas has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Speed optimality analysis for evaluating the optimality of a powertrain
    Patent number: 10801921
    Abstract: Systems and methods for improving fuel economy in vehicles such as Class 8 trucks are provided. In some embodiments, signals indicating states of the powertrain are collected and used to generate fuel rate optimization values. Fuel rate optimization values may indicate a difference between optimum fuel flow rates and actual fuel flow rates during a vehicle drive cycle. Recorded fuel rate optimization values may be used to compare different vehicle configurations during testing, and may also be used to evaluate vehicle performance during real-world operation.
    Type: Grant
    Filed: September 16, 2019
    Date of Patent: October 13, 2020
    Assignee: PACCAR INC
    Inventors: Christopher Michael James Douglas, Michael Douglas Gerty, Mark G. Malowicki
