Abstract
Mild-Hybrid Electric Vehicles (mild-HEVs) earned market share over the last years an as effective roadmap to limit air pollution in big cities. In addition to this role, hybrid propulsion can be used to avoid dry clutch overheating in mild-HEVs equipped with automated manual transmissions. Indeed, high thermal level could result in serious damaging of dry clutch linings with very fast decay of expected lifespan affecting vehicle reliability. This paper shows results of vehicle launch simulations to highlight how the propulsion due to electric motor can effectively reduce clutch thermal stress during the slipping phase.
Highlights
In the last decades, Hybrid Electric Vehicles (HEVs) and Electric Vehicles (EVs) are gaining significant share of the automobile market
Series HEVs differ from parallel HEVs in the role of internal combustion engine (ICE) as energy from combustion engine is converted into electric energy to charge the battery pack or to propel the wheels (Chan, 2007; Oh et al, 2007; Pisu & Rizzoni, 2007)
This study aims at investigating the beneficial role of electric motor (EM) to limit temperature rise in dry clutch during HEV launch manoeuvre
Summary
Hybrid Electric Vehicles (HEVs) and Electric Vehicles (EVs) are gaining significant share of the automobile market Their success is mainly due to higher fuel efficiency than conventional vehicles which results in a reduction of pollutant emissions. By analysing the driveline structure, in parallel HEVs both the internal combustion engine (ICE) and electric motor (EM) can propel, separately or at the same time, the vehicle wheels. The importance of moving toward sustainable mobility is strongly linked to the need to reduce air pollution and the greenhouse effect, especially in big cities. To this aim, many studies have been proposed to improve the efficiency of hybrid vehicles
