Real-Time Capable Driving Strategy for EVs Using Linear MPC

Abstract

Recent trends in automotive industry reveal strict movement towards electromobility. However, limited electric vehicle (EV) range poses a major impediment of this movement which is tackled by development of sophisticated advanced driver assistance systems (ADAS). This paper presents a novel approach for computation of energy efficient speed trajectories for EVs. The proposed approach aims for application in an intelligent cruise controller (ICC) framework utilizing lookahead data for the road provided by advanced navigational systems and a simplified vehicle model. To evaluate the algorithm's performance, a simulative study is carried out comparing optimized speed trajectories to baseline ICC. Distinctive feature of this work presents the derivation of a simplified powertrain model which is used in linear MPC. This makes the proposed approach perfectly suitable for prototypical implementation and offers potential for transfer to standard electronic control units.
