Conventional energy management strategies (EMSs) of hybrid electric vehicles (HEVs) only utilize in-vehicle information, such as an acceleration pedal, velocity, acceleration, engine RPM, state of charge (SOC), and radar.This paper presents a new EMS using out-vehicle information obtained by vehicle to everything (V2X) communication.The new EMS integrates cooperative eco-driving (CED) guidance and an adaptive equivalent consumption minimum strategy (A-ECMS) based on V2X communication information and road information.
CED provides a la rams crop top guide signal and a guide speed to the driver.It guides pedal behavior in terms of coasting driving, acceleration and deceleration, and target speed.A-ECMSs calculate the target SOC based on the simplified road information of the planned route and reflects it in the equivalent factor.
An integrated driving hardware-in-the-loop (IDHIL) simulator is also built to prove the new EMS by integrating a V2X communication device, a VANET simulator, and a vehicle simulator.The IDHIL test results demonstrate the validity and performance of the il barone wine proposed EMS in a V2X communication environment.
