Methods and systems for improving fuel economy and reducing emissions of a vehicle with an electric motor, an engine, an energy storage device, and a controller are disclosed. The method includes obtaining current state information including a current hybrid control surface, and determining a target hybrid control surface for the vehicle based on the current state information.

Method and system for a hybrid power control in a vehicle

A method, an optimization controller, and combustion engine are disclosed. The method includes determining, by an optimization controller, values of a performance parameter of a target vehicle using characteristics of at least two platoons travelling on a roadway, each of the values corresponding to a platoon of the at least two platoons; selecting, by the optimization controller, one of the at least two platoons based on a comparison of the values of the performance parameter, and coordinating, by the optimization controller, for the target vehicle to join the selected of the at least two platoons.

Optimization of mission efficiency through platoon opportunity assessment

Apparatuses, methods and systems including dynamic estimations of vehicle mass and road grade estimation are disclosed. One exemplary embodiment is a method including operating a vehicle system to propel a vehicle, determining with a controller a vehicle mass estimate and an uncertainty of the vehicle mass estimate, evaluating with the controller the uncertainty of the vehicle mass estimate relative to at least one criterion, if the uncertainty of the vehicle mass estimate satisfies the criterion, determining with the controller a road grade estimate, and controlling with the controller utilizing the road grade estimate at least one of a vehicle speed and an engine output.

Vehicle controls including dynamic vehicle mass and road grade estimation during vehicle operation

Systems and methods for controlling performance characteristics of a vehicle are provided. A system for controlling performance characteristics of a vehicle includes a memory storage device including at least one torque curve profile stored thereon. The at least one torque curve profile includes a mapping of accessible torque for the vehicle with respect to an engine speed of an engine coupled to the vehicle. The system also includes an electronic control unit operatively coupled to the memory storage device, the electronic control unit configured to re-map the at least one torque curve profile in response to receipt by the electronic control unit of an electronic signal indicating a change in a vehicle condition.
