Objectives:The electrical system of automotive vehicles belongs to the most important components of a car. The necessary knowledge and the skilled handling in the supplied technogies are the
objectives of this lecture. By means of practical examples the student learns the basics about
modern electrical systems in vehicle applications of today and what is exspected for tomorrow. A lot of the presented procedures and strategies can be transfered directly to other electrical applications as toolmanufacturing, electrical building equipment, renewable energy,
offshore technology, railway electronics, or aircraft applications .Due to the learned lessons the student is able to follow the important procedures of designing an electrical system in one of the applications mentioned above.
Course contents:The automotive vehicle of tomorrow is becoming more comfortable and much safer ( due to the driver assistence systems).Especially the electrical systems are supporting these targets.
Today there is a step by step change from the fuel dependent car to the electrical driven car.
Starting with hybrid cars first that are able to cover small distances, electrical driven only, the target is the electrical driven car for great distances. This important trend is already considered by the learning content of the lectures.

The lecture is devided into two parts:
1) lectures about the required knowledge of the applied hardware
2) lectures about the required knowledge of the applied software

Lectures respecting 1) are containing the following items:
- Energy generation ( types of alternators, types of fuel cells)
- Energy storage ( types of batteries)
- Energy transport ( topology, harness, connectors, high voltage application)
- Electric loads ( E-drive, CSG, Auxiliary aggregates, lighting, aircondition)
- Protection of electric loads and harness ( calculation of fuses, network design)
- Electromagnetic compatibility (EMC) (Interference, Susceptibility,ESD,Surge,
Transient Conduction, Load Dump, Jump Start)Hybrid cars, Electric vehicles
- Investigation of worst case scenarios
- Safety, reliability, availability (use of of FMEA- and FTA-methodologies)

Lectures respecting 2) are containing
- Applied BUS-Concepts in automotive electronics
- LIN – BUS
- J1850 (USA)
- Low Speed CAN – BUS
- High Speed CAN – BUS
- TTCAN – BUS
- Flex Ray
- MOST
- Bluetooth

Significant for the electrical system design are topics as:
- Topology requirements
- Master-Slave Concepts
- Client Server and Publisher Subscriber Models
- Different protocols
- Gateway functions
- Data management and consistence control in network applications
- Test procedures
- EMC Considerations
- Change management
- Quality management (SPICE, hardware in the loop, V-model)
