SYSTEM AND APPROACH FOR DYNAMIC VEHICLE SPEED OPTIMIZATION

A system and approach for a vehicle system. The vehicle system may include a vehicle (10), a propulsion device (14) (e.g., a combustion engine or electric motor), and a controller (16). The propulsion device (14) may at least partially power the vehicle (10). The controller (16) may be in communicat...

description A system and approach for a vehicle system. The vehicle system may include a vehicle (10), a propulsion device (14) (e.g., a combustion engine or electric motor), and a controller (16). The propulsion device (14) may at least partially power the vehicle (10). The controller (16) may be in communication with the propulsion device (14) and may control the propulsion device according to a target speed of the vehicle. The controller may include a model (30) of energy balances of the vehicle and may use the model to estimate energy losses over a travel horizon of the vehicle. The controller may optimize a cost function (28) over the travel horizon of the vehicle based at least in part on the estimated energy losses to set an actual speed for the vehicle. The estimated energy losses may include one or more of aerodynamic drag, vehicle friction, and conversion efficiency from the propulsion device.
