4. 22. Model Based Vehicle Level Diagnosis for Hybrid Electric Vehicles

   Author : Christofer Sundström; Lars Nielsen; Erik Frisk; Linköpings universitet; []
   Keywords : ;

   Abstract : When hybridizing a vehicle, new components are added that need to be monitored due to safety and legislative demands. Diagnostic aspects due to powertrain hybridization are investigated, such as that there are more mode switches in the hybrid powertrain compared to a conventional powertrain, and that there is a freedom in choosing operating points of the components in the powertrain via the overall energy management and still fulfill the driver torque request.

5. 23. Vehicle Level Diagnosis for Hybrid Powertrains

   Author : Christofer Sundström; Lars Nielsen; Erik Frisk; Mikael Norrlöf; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : There are possibilities to reduce the fuel consumption in trucks using hybrid technology. New components are added when hybridizing a vehicle, and these need to be monitored due to safety and legislative demands. Diagnosis aspects due to hybridization of the powertrain are investigated using a model of a long haulage truck. READ MORE

6. 24. Methods for Automated Design of Fault Detection and Isolation Systems with Automotive Applications

   Author : Carl Svärd; Mattias Nyberg; Erik Frisk; Mattias Krysander; Vincent Cocquempot; Linköpings universitet; []
   Keywords : ;

   Abstract : Fault detection and isolation (FDI) is essential for dependability of complex technical systems. One important application area is automotive systems, where precise and robust FDI is necessary in order to maintain low exhaust emissions, high vehicle up-time, high vehicle safety, and efficent repair.

   Abstract : To efficiently transport goods by heavy-duty trucks, it is important that vehicles have a high degree of availability and in particular avoid becoming standing by the road unable to continue the transport mission. An unplanned stop by the road does not only cost due to the delay in delivery, but can also lead to a damaged cargo. READ MORE
