Lectures

The lecture consists of one lecture (2 SWS=90 minutes per week) and practical exercise (1 SWS=45 minutes a week) (2/0/1).

Embedded systems are used in a wide range of applications. An instance of that are intelligent sensors which not only have a measurement function but also an embedded processing unit (e.g. a microcontroller). This allows the sensors to be directly connected to a communication system and makes all data available to the relevant control units.

The aim of this course is to introduce the students to those systems which are necessary in vehicle design. As part of the lecture, the relevant basic knowledge will be imparted, and in the practical training improved (with microcontroller programming). The lecture encompasses the following topics:

• Introduction and Motivation
• Basics, Requirements for the Embedded Control Systems
• Architectural Features of Modern Microcontrollers and Microprocessors
• Classification, Introduction to 16-Bit Microcontroller Architecture (the C166 Family)
• Components of Microcontrollers (Using the Example of the C167), Samples of Programmes
• Software (Programming, Real-Time Operating Systems)
• Design Process

In the practical training, students are required to independently programme microcontrollers of various embedded systems. The course objective is: becoming acquainted with an embedded system.

• Hardware-Based Programming (C programming)

Electronic subsystems play an essential role in modern vehicles. New features are most often realised electronically or at least partly electronically. Modern driver assistance systems are an example of that. Furthermore, already existent, purely mechanical features are increasingly replaced by electronic features. Examples of that are the mechanical steering post and the modern steer-by-wire technology.

The aim of this course is to give students an insight into vehicle electronics (as part of the lecture) and to impart practical knowledge about the handling of the technologies discussed in class (as part of the practical training). The lecture encompasses the following topics:

• Introduction and Motivation
• On-board Electrical Systems for Power Supply and Hybrid Drivetrains
• Electronic Systems in Motor Vehicles
• Advanced Driver Assistance Systems
• Communication in Motor Vehicles

The motor vehicle as a system as such is made up of various subsystems which need to interact with each other, e.g. allocation of vehicle features to various control units. In order to provide the necessary data exchange (sensor values, control information etc.), communication systems are implemented in the vehicle. Serial bus systems are used to keep communication channels short and to reduce the complexity of the communication systems

The aim of this course is to introduce students to serial bus systems which are currently used in vehicles. The lecture encompasses the following topics:

• Introduction, Motivation
• Classification Communication Systems
• CAN - Controller Area Network
• LIN - Local Interconnect Network
• MOST - Media Oriented System Transport
• FlexRay
• Automotive Ethernet
• Car2Car & Car2Infrastructure Technologies
• Car2Car & Car2Infrastructure Use Cases
• Car2Server
• Safety & Security

In practical training, students get the opportunity to field-test the knowledge they have gained in the lecture, using CAN bus systems. In order to do that, the basics of bus systems are concentrated on and then students are required to accomplish a communication programming task. Part of  that is also restbus simulation (since one will come across this in the design process). Practical training consists of:

• Basics of CAN
• Distributed functions

Connected Automated Mobility

With the Connected Automated Mobility lecture, the Professorship of Vehicle Mechatronics imparts knowledge and skills for system development in the field of highly automated driving (HAD) and automated driver assistance systems (ADAS).

Example explanations and practical tests are related to the main application area of ​​road traffic, but the systems and functions discussed are also considered in the context of other mobility variants such as rail transport or aviation, or can be transferred there.

The event looks at technical aspects:

• What does the overall system for fully automated driving include? What subsystems and components does it consist of and how are the relationships?
• Which sensors are used for the necessary environment detection? How do these sensors work? How are they integrated into the overall system? How are the sensor data processed, merged and made usable as an image of the environment?
• How does the decision-making process for navigation and maneuver planning work? How is this implemented? How is it decided which driving trajectory should be followed? How are the possible trajectories calculated?
• How is the vehicle guidance influenced? Which actuators are necessary and how do they work? Does the trajectory tracking control work? How is the movement in the longitudinal and transverse directions implemented in terms of control technology?

In addition, development-relevant aspects are also considered:

• Which regulations, standards, norms and laws apply to the development and use of automated driving systems?
• What is Functional Safety (FUSA) and how is it developed in accordance with it?
• What is the Safety of the Intended Functionality (SOTIF)? How is this integrated into the development process and what effects does it have?
• How are automated driving functions secured and what does testing for approval include?

In order to convey this knowledge and its practical testing, the event consists of lectures, exercises and practical courses (you can find the relevant scope in your current module description). In addition to design tasks for system development, the exercise prepares the practical courses or laboratory tests or tests on real vehicles. There, technical aspects such as sensor data acquisition or longitudinal and lateral control are experienced in practice.

Modern vehicles are highly-distributed systems in which various subsystems interact with each other. Functional distribution can be a source of error. Since the complexity of the distributed system "Vehicle" constantly increases, the sources of error also increase, which asks for comprehensive possibilities for fault finding (in the case of an error) and fault prevention. Diagnostics are an integral part of today’s automotive engineering, which is why this topic will be explored further in this lecture. The lecture encompasses the following topics:

• Introduction and Motivation Diagnostics of Vehicles
• Basics: Process Error Detection, Event Chain Analysis
• On-Board Diagnostics (OBD), European On Board Diagnostics (EOBD), GVU German Legislature
• Diagnostic Protocols and Transport Protocols, MCD-Systems, Testing Technologies, Standards (ODX, OTX)
• Diagnostic Methods I
• Diagnostic Methods II
• Function Development, Development Process, Diagnostics, Event Chain Analyses
• Summary

Additionally, in the practical training, students will deepen their knowledge. In part one, students are asked to diagnose a fault in an example system. In part two, students carry out a restbus simulation since this is an integral part of most diagnostics design processes. The practical training encompasses the following:

• Exercise 1: Basics, Application of a Tester, Diagnostics
• Exercise 2: Restbus Simulation (Communication Error, Window Lifter Control, Plausibility), Diagnostic Protocols
