A method for estimating a remaining range of a vehicle battery charge includes identifying at least one route characteristic of a portion of a selected route, determining a vehicle energy consumption profile for a vehicle, and determining a current state of charge of a vehicle battery of the vehicle. The method also includes determining, for the selected route, a route energy consumption profile and calculating an estimated remaining charge for the vehicle battery at an end of the selected route based on the state of charge of the vehicle battery and the route energy consumption profile. The method also includes, in response to a determination that the estimated remaining charge is less than a lower limit of the vehicle battery charge range, determining a target vehicle speed profile based on the at least one route characteristic, the vehicle energy consumption profile, and the state of charge of the vehicle battery.

A method for controlling vehicle propulsion may include identifying at least one route characteristic of a portion of a route being traversed by a vehicle and determining a profile for a target vehicle speed based on the at least one route characteristic and a vehicle energy consumption profile. The method may also include, in response to detecting a lead vehicle, determining a vehicle speed of the lead vehicle and determining whether to avoid triggering initiation of the vehicle follow mode by the vehicle propulsion controller based on (i) a distance between the vehicle and a triggering threshold and (ii) the vehicle speed of the vehicle. The method may also include, in response to not triggering vehicle follow mode, determining, based on the vehicle speed of the lead vehicle and the profile for the target vehicle speed, a traveling distance between the vehicle and a trigger threshold.

A method for torque split arbitration in a vehicle includes identifying at least one route characteristic of a portion of a route being traversed by the vehicle. The method further includes determining a target torque split based on the at least one route characteristics. The method further includes generating a first output torque demand that corresponds to a product of a first portion of a target torque demand to be provided by a first propulsion unit and a ratio of a total propulsion system torque demand and the target torque demand. The method further includes generating a second output torque demand based on the first output torque demand.
