Abstract: Systems and apparatuses include one or more processing circuits including one or more memory devices coupled to one or more processors. The one or more memory devices are configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to: receive a parameter regarding operation of a first vehicle of a first platoon; compare the parameter to a first predetermined threshold; responsive to determining that the parameter satisfies the first predetermined threshold, determine an exit parameter for the first vehicle; and cause the first vehicle to exit the first platoon based on the exit parameter.

Abstract: Methods and systems for a powertrain power management in a vehicle with an electric motor, and an engine are disclosed. The methods and systems involve a powertrain that is operatively coupled to the engine and the electric motor, and an optimizer module operatively coupled to the powertrain. The optimizer module receives an operator information to travel a route from a remote management module, receives current route information for the route from a mapping application in response to the operator information, measures current vehicle status information for the hybrid vehicle, and decides a power management strategy for the vehicle based on the current route information and the current vehicle status information.

Abstract: A system and method for power management of hybrid electric vehicles is provided. In some implementations, a plug-in series hybrid electric vehicle may include an engine, a motor/generator (MG), a traction motor, an energy storage device, and a controller. The controller is coupled to the engine and the MG to control operation of the engine and the MG such that a state-of-charge (SOC) of the energy storage device tracks a dynamic reference SOC profile during a trip and an average engine power (AEP) is maintained above a threshold. In some instances, maintaining AEP above a threshold supports emission control of the vehicle.

Abstract: Methods and systems for improving fuel economy and reducing emissions of a vehicle with an electric motor, an engine and an energy storage device are disclosed. The methods and systems involve obtaining lookahead information and current state information, wherein the lookahead information includes a predicted vehicle speed, and the current state information includes a current state of charge (SOC) for the energy storage device coupled to the electric motor; and determining, based on the lookahead information and the current state information, a target power split between the energy storage device and the engine.

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.

Abstract: A system is provided for performing an automated range estimation process for an electric vehicle using a processor. Included in the system is a range estimator configured to estimate an initial value of an energy required to travel a unit distance for the electric vehicle. The range estimator generates a first estimation model based on a correlation between a maximum all-electric-range and the energy required to travel a unit distance. Then, the first estimation model is adjusted based on one or more predetermined driving conditions. The maximum all-electric-range of the electric vehicle is updated based on the adjusted first estimation model. An estimated range of the electric vehicle is calculated based on the updated maximum all-electric-range of the electric vehicle and a fraction of total energy capability remaining in the electric vehicle. The estimated range of the electric vehicle is outputted and is used to control the electric vehicle.
