Efficient gear shifting strategies for green driving policies

The problem of deriving efficient automatic gear shifting policies in cars equipped with AMT (Automated Manual Transmission) is investigated in this paper with the aim at minimizing fuel consumption. Two different online gear shifting strategies have been fully analyzed and are here described: (1) E.G.A. (Efficient Gear Actuator), based on the choice at each time instant of the most efficient gear according to efficiency maps; (2) G.F.A. (Genetic and Fuzzy Algorithm), achieved from the synergical use of Genetic Algorithms and Fuzzy Logic. Comparative tests carried out on the NEDC cycle will finally be presented for both strategies in order to show their effectiveness and allow comparisons.

Control IP's Sharing: From Configurable Mechatronic Control to Autosar SW-C Package. A New Model Business Scenario across Automotive OEMs and Component Supplier and the New Roles of SW IP's Supplier and SW IP's Integrator

The main drivers of todays automotive applications are the reductions of ECU systems cost as well as the development of new innovative functions such as: perceived vehicle performances, active vehicle safety, new emission laws (EU5, EU6) and CO2 reduction. On the other hand more and more resources are spent on adapting the Intellectual Properties (IPs) control solutions to different electronic control unit eroding precious time for the development and validation of the project. To match challenging Time to Market constraints (less than 18 months for a new application) versus Automotive functions complexity increasing, without sacrificing system quality and robustness, a new approach appears unavoidable, perhaps a change of paradigm, where relationships and cooperation between Original Equipment Manufacturer (OEMs) and Suppliers as well as Supplier to Supplier interfacing have to evolve into a new model for both development and commercial issues. This emerging scenario has been taken into account by the AUTOSAR (AUTomotive Open System ARchitecture) consortium defining technologies and process in order to permit to share SW IPs over different platforms and applications. This paper describes, using a real example of a mechatronic scalable control IPs, developed with model based approach technique and configurable on different applications using the AUTOSAR technology, the approach followed by Magneti Marelli (MM) to play the new roles of SW IPs supplier and SW IPs integrator.
