Electric Motor and Dry Clutch Control in Launch Manoeuvres of Mild-Hybrid Vehicles Based on AMT/DCT Transmissions

摘要

Mild-Hybrid Electric Vehicles (mild-HEVs) earned market share over the lastyears an as effective roadmap to limit air pollution in big cities. In additionto this role, hybrid propulsion can be used to avoid dry clutch overheatingin mild-HEVs equipped with automated manual transmissions. Indeed,high thermal level could result in serious damaging of dry clutch liningswith very fast decay of expected lifespan affecting vehicle reliability. Thispaper shows results of vehicle launch simulations to highlight how thepropulsion due to electric motor can effectively reduce clutch thermalstress during the slipping phase.
