Future Clutch Actuation and Control for HEV Powertrains

Important results from the project

The main purposes with the project ´Future clutch actuation and control for HEV powertrain´ were to close knowledge and technology gaps related to the new demands with the increasing penetration of Hybrid Electrical Vehicles at the market, and to act as an enabler for introducing new technology. The purpose with this pre-study (WP1) was to investigate and analyze future requirements for a clutch actuation, and perform a system definition. The goals with the pre-study in the project were met.

Expected long term effects

This pre-study supports the goals to introduce new technology to reduce emissions and to close these knowledge and technology gaps related to an increasing market penetration of hybrid cars and such technology. It also supports to strengthen the Swedish automotive industry and the collaboration between academy, tier 1 and SME.

Approach and implementation

Since this is only a pre-study, the implementation is mainly related to go further with the findings and go into a concept development phase. The pre-study was made by Kongsberg Automotive and Vicura. The first part was to go through literature and available information from competitors within the field, and look into how they have done. Also a comparison and a gap analysis were done. With the Vicura EREV concept as a reference we also went through the clutch control functions and requirements, also including a small part with the shift and control functions and requirements. Finally we made a system definition for a future clutch actuator, and lined up some conclusions and the potential for the future.
