  • Patent number: 11352008
    Abstract: A system, method, and apparatus includes management of coasting during operation of a vehicle. Speed of a vehicle is monitored during a coasting event and is compared against a threshold to determine whether to remain coasting or re-engage an engine to a driveline. If instantaneous speed exceeds the threshold, predicted speed can be used to determine whether to permit short duration excursions, or to re-engage the engine to the driveline. These techniques can be used whether the vehicle is slowing down below a threshold or speeding up above a threshold.

  • Publication number: 20210270622
    Abstract: Technologies for energy consumption optimization include a computing device in communication with a fuel cell electric vehicle (FCEV) or other hybrid architecture vehicle. The computing device receives mission parameters and an optimization objective associated with the FCEV and cost information associated with external energy sources. Each external energy source corresponds to an onboard energy storage device of the FCEV. The computing device determines an optimized energy source schedule based on the mission parameters, the optimization objective, and the cost information using a vehicle model of the FCEV. The optimized energy source schedule is indicative of supplying one or more of the onboard energy storage devices with energy from the associated external energy source. The computing device may recommend a component replacement for the FCEV using a component aging model. Other embodiments are described and claimed.

  • Publication number: 20210269042
    Abstract: A system for controlling an overtake maneuver of a control vehicle comprises a controller structured to determine an overtake velocity for the control vehicle traveling in a vehicle lane to overtake a front vehicle traveling ahead of the control vehicle in the vehicle lane. The controller determines an overtake time for the control vehicle to overtake the front vehicle based on the overtake velocity. The controller determines a direction of traffic in an overtake lane that is adjacent to the vehicle lane. If the direction of traffic in the overtake lane is the same as a direction of traffic in the vehicle lane, and the overtake velocity is less than or equal to an allowed velocity, the controller executes the overtake maneuver by one of adjusting a parameter of an engine and/or a transmission of the control vehicle or providing a command to an operator of the control vehicle.

  • Patent number: 10960884
    Abstract: A system, method, and apparatus include a controller structured to predict a change in speed of a vehicle in advance of upcoming terrain and inhibit a coasting event if the speed exceeds a limit. In one form a velocity of the vehicle is predicted using a physics based model of the vehicle within a look ahead window in front of a vehicle. Such a look ahead window can be distance or time based. In another, speed of a vehicle is monitored during a coasting event and is compared against a threshold to determine whether to remain coasting or re-engage an engine to a driveline. The threshold is a function of road grade, and permits a larger deviation from set speed at low grade than at high grade. The function can be based on road grade and vehicle weight.
