Abstract

Use of multi-time domain optimization of vehicle dynamics and powertrain control of a vehicle is provided. And performing long-time-domain optimization on the travel of the vehicle, and determining an optimal value function. Data from a powertrain and / or connectivity feature is received from one or more components of a vehicle. And performing short-time domain optimization on the travel by using a rollout algorithm, the optimal value function and the received data. The operation of the vehicle is adjusted using the results of the short-time domain optimization.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims US Provisional Patent Application No. 62 / 931,293, entitled "METHOD FOR VEHICLE DYNAMICS AND POWERTRAIN CONTROL USINGMULTIPLE HORIZON OPTIMIZATION," filed November 6, 2019, and entitled "METHOD FOR VEHICLE DYNAMICS AND POWERTRAIN CONTROL USINGMULTIPLE HORIZON OPTIMIZATION" , the disclosure of which is expressly incorporated herein by reference in its entirety. [0003] Statement of Government Support [0004] This invention was made with government support under award number DE-AR000794 from the Department of Energy's Advanced Research Projects Agency. The government has certain rights in this invention. Background technique [0005] The objective of the nonlinear dynamic optimization problem formulated in the spatial domain is to minimize the fuel consumption of the vehicle throughout the trip. One benefit of spatial trajectory formulation is that it lends itself well to the incorporation of rou...
