Short Bio

Eneko Otaola studied Industrial Engineering at Bilbao Faculty of Engineering, specialising in Systems and Control Engineering. He holds a MSc in Automotive Mechatronics from Cranfield University, where he finished his academic period and received the Industry Interaction Price for his research thesis in collaboration with Delta Motorsport company about Autonomous  Vehicle Control at the limit of handling. Then, he had the opportunity to work for a year at IDOM Consulting, Engineering, Architecture company as Design Engineer. He is passionate about mathematical modelling, control strategy design and vibrational analysis. 

Project description

The project goal is to improve the NVH behaviour of the transmission by using the available electric traction machine of a hybrid vehicle. The goal is to use already existing components in the system for active vibration control. Serval questions have to be tackled within this project in order to find a suitable approach:

  • What is the vibration pattern of the transmission?
  • What kind of control approach is suited?
  • What are the limitations by the traction machine?
  • Which and how many sensors are required?

Besides developing and investigating strategies for NVH-improvements, the possibilities of improving the efficiencyvia smart operational strategies of the traction machine will be investigated. Simulations will be carried out to identify useful approaches. Promising strategies will be implemented and tested on an experimental vehicle. This vehicle will also be used to collect driving data. This data will then be used to generate individual driving cycles which can be used for the transmission and active control design, allowing a comparison to a standard driving cycle.
