Abstract

Eco Approach and Departure (Eco-AnD) is a Connected and Automated Vehicle (CAV) technology developed to reduce energy for crossing a signalized intersection or set of intersections in a corridor that features vehicle to infrastructure (V2I) communication capability. Eco-AnD technology uses the information of the signal phase and timings (SPaT) received from the V2I communication to optimize the vehicle’s speed profile and produce an energy-efficient maneuver to cross the intersection.

The Eco-AnD algorithm is devised for two vehicles (GM-Volt Gen II & GM-Bolt), both with different powertrain architectures but capable of working in electric-only mode. In simulations, the developed algorithm showed an energy-saving potential of 70-90 kJ per intersection around the corridor of the MTU drive cycle for both vehicles. For the RSU loop (a subset of MTU drive cycle) up to 8 % of energy reduction is observed. Vehicle level testing of the optimized speed profiles was carried out at the American Center of Mobility (ACM) on GM-Volt Gen II to demonstrate an energy-saving of 40-50 kJ per intersection on real road conditions.
