Abstract

U današnje vrijeme dolazi do sve veće svijesti očuvanju okoliša. Često je na udaru automobilska industrija jer se smatra jednim od najvećih zagađivača okoliša. Iz tih se razloga energetski sustavi sve više okreću prema obnovljivim izvorima energije a transport prema elektrifikaciji putem hibridnih i električnih vozila. Iako je većina komponenti koja sačinjava hibridni električni pogon vozila već odavno poznata te njihov razvoj dolazi do vrhunca, nije još točno određen i definiran pravac najboljeg i najefikasnijeg upravljanja hibridnim pogonima, posebno onima kod kojih je električni motor relativno male snage (tzv. umjerena hibridna vozila). Pod pojmom upravljanja u ovom kontekstu smatra se pojam nadređene strategije upravljanja koji se bavi time kako najbolje iskoristiti komponente hibridnog sustava u svrhu smanjenje potrošnje goriva. Iz tog razloga u ovom radu se obrađuje jedan od mogućih načina upravljanja umjerenim hibridnim električnim vozilom paralelne P2 konfiguracije. Razvija se strategija temeljena na bazi pravila (engl. rule-based), koja ovisno o zadanim pravilima definira stanje i parametre rada zadanih komponenti. Unutar upravljačke strategije definiraju se takozvane funkcionalnosti hibridnog vozila prema prethodno spomenutoj bazi pravila. Funkcionalnosti koje se razmatraju jesu: sporohodna električna vožnja, pasivno i aktivno električno krstarenje te regenerativno kočenje. Razvijena upravljačka strategija implementira se i ispituje unutar simulacijskog paketa AVL CRUISE, pri čemu je kod simulacijskog ispitivanja naglasak na analizi smanjenja potrošnje goriva te utjecaja voznost na vozila.

Abstract (english)

In recent years, environmental awareness is growing. Automotive industry is often hit by criticism as it is considered as one of the largest environmental polluters. For these reasons energy systems are increasingly turning towards renewable energy sources, and transport systems towards electrification through hybrid and electric vehicles. Although most of the components which constitute the hybrid system have long been known and their development is at its climax, the best and most efficient control strategy design for such systems has not yet been defined and determined, especially for those with relatively low power electric motors (so-called mild hybrid electric vehicles). Here, the control strategy term refers to high-level control strategy for hybrid powertrain, which combines the hybrid system components with the aim of reducing the fuel consumption. For this reason, this paper deals with one of the possible approaches of high-level control strategy development for mild hybrid electric vehicle in P2 configuration. A rule-based control strategy is developed, which, depending on the given rules, defines the operation mode and parameters of the hybrid powertrain components. Within the control strategy, the so-called hybrid vehicle functionalities are defined according to the previously mentioned rule base. The functionalities to be considered are: eCreep, eCoasting, eSailing and regenerative braking. The developed control strategy is implemented and verified within the simulation package AVL CRUISE, whereby simulation testing focuses on analysis of fuel consumption reduction and the driveability of the vehicle.
