PICMicro MCU in Mechatronics: Hands On
This workshop focuses on the use of the PICMicro MCU by Microchip Technology in Mechatronics. The workshop consists of two components: Introduction to the PIC 16F877 and development tools; and Hands-on experimentation. Due to the hands-on nature of the workshop, attendance is limited to 10 people, equipped with a laptop. Fundamentals of programming in C (not C++) will be required.
15:00–15:20
Introduction to the PICMicro 16F877
15:20–15:30
Software installation on your laptop
15:30–16:00
Hands on: Digital I/O
16:00–16:30
Hands on: Serial communications with a PC
16:40–17:00
Hands on: Analog loopback and sampling
17:00–17:30
Hands on: Realtime issues
17:30–18:00
Hands on: Realtime PID control using the PIC
The hands-on session shall be run in the following manner. Each participant shall bring their own laptop to which we install a compiler. We shall supply you with the code for each hands on session. The code shall be explained and discussed. Minor changes shall be suggested for you to change in the code in order to gain understanding. You then compile your program on your PC to see that it is free of error. You then take the compiled code to the hands-on station and download the code to the PIC and run and observe your program's response.
| Mechatronics Realizations in Hybrid Electric Vehicles
Aim of this tutorial is to bring to mechatronics teachers and researchers from academia a concrete feeling of the current state-of-art in the automotive field, particularly on Hybrid Electric Vehicles. The participants, world-leading automakers and automotive research centers, will present their recent realizations and discuss both problems already solved through mechatronics, and future problems which will need attention by mechatronics researchers.

HEV Technologies for Passenger Cars – An Overview, Ralf Bady, RLE International, Germany
Hybrid Electric Vehicles are one promising option to reduce fuel consumption and emissions of future passenger cars. Different technologies have been investigated within the past 30 years, since 1997 first technologies have been implemented in production vehicles and have been made available first on the markets in Japan, US and also now Europe. Different hybrid technology configurations will be presented and discussed. The latest vehicle applications will be summarized.

INMOVE – Concept of a Charge-Sustaining Hybrid Drive Train, Christian Renner, Ralf Bady, FKA mbH Aachen, Germany
The R&D-project INMOVE has dealt with the development and realization of a hybrid drive system. The main objective of the project has been the definition of such a power train, the research on optimized technology and finally the prototyping of two demonstrators (Citroën Berlingo), in order to design and evaluate an appropriate hybrid driving strategy. To achieve a good fuel economy with a cost effective solution a parallel hybrid drive has been developed. The drive train is of the “single shaft” configuration, where the electric motor works on the input shaft of the manual gearbox. The clutch is electronically controlled and automated. The different components of the drive system are connected by a CAN-bus. The overall control, the drive system management and especially the driving strategy are realized by a vehicle management unit. With finishing the build up of the first prototype end of 1999 and the second prototype end of 2000, optimization and analysis under real conditions have been possible. Measurements of the fuel economy show comparatively low results and verify the overall functionality of the subsystems as well as the strategy.

Hybrid Electric Vehicle Realization at Fiat, Pasquale Campanile, Centro Ricerche Fiat, Italy
The concept of mild hybrid vehicle developed by CRF, named ECODRIVER, is a parallel configuration consisting of a dual clutch system with a robotised gearbox.The objective is to achieve substantial fuel consumption reduction, while keeping performance and comfort as much as possible equivalent to the ICE powered reference vehicle.The objective has been achieved combining a gasoline engine with an asynchronous electric motor and through the implementation of functions such as stop&start, electrical power assist during acceleration, regenerative braking.Engineering challenges regarded packaging and weight optimisation of powertrain and electrical components, but the key factor is the optimal control strategy. Only through an optimal control is in fact possible to achieve the best matching of the two motors for maximum efficiency, unimpaired driveability during up and down gearshifting, smooth stop & start operations for customer acceptance.

Volkswagen Hybrid Electric Vehicles: An Overview about Past, Present and Future Activities and the Influence of Mechatronics on Functionality of Key Components of the Hybrid Powertrain, Siegfried Koehle, Volkswagen AG, Germany
Volkswagen has been conducting research into hybrid vehicle concepts since the beginning of the 1970s. Some examples of built prototypes and the research results will be introduced. The goal was to combine the advantages of the conventional combustion engine and the electric motor in terms of fuel consumption and environmental benefits. These activities led to the VW Golf Hybrid tested in a 3 year fleet test in Zurich, Switzerland and to the first series production hybrid vehicle, the Audi Duo, equipped with a 66 kW TDI engine combined with a 29 kW synchronous electric motor and a 5 speed semi automatic gearbox. One of the key components of a hybrid drive train is an automatic transmission with robotised gear shifting and clutches which enables the comfortable and effective use of either the combustion engine or the electric motor or both in addition. The realization of this function without Mechatronics today is not imaginable. The vehicle management computer has to decide about the needed actions within the powertrain and mechanical actuators have to shift gears, operate clutches etc. Other mechatronic components include power steering, brake by wire, air conditioning etc. which do influence car fuel consumption.
