Objectives:
After successfully completing this module the students shall be able to:
• have an overview of vehicle electronics, especially in the automotive sector
• understand the latest developments in automotive technology
• use electrotechnical fundamentals to describe the development and manufacturing of vehicle components such as sensors, actuators and bus systems
• know the basics of software architecture for vehicle electronic systems / control units.

Group Project – Challenges and Potential of using Ultrasonic Sensor in the near field as Safing sensor

Supervisors: Professor Thomas Brandmeier and Mr. Gerald Joy Alphonso Sequeira

The students will model investigate the ultrasonic sensor in the near field (0.5 to 10m) i.e. just before the crash to validate the predictions made in the far and midfield by other sensors. There are many challenges such as speed limit for use of ultrasonic sensor, attenuation of the signal strength due to the wind, doppler shift, etc. These challenges will be listed and have to be investigated experimentally to understand is it possible to extend these limits and reduce attenuation.

Additionally, there are opportunities by using multiple sensors to find the position and the using multiple frames the direction of movement.

In the last phase, the noise of the sensor signal to the weather conditions such as rain or fog would be investigated in the CARISSMA indoor test area.

By doing this group project the students will
- learn about signal processing and ultrasonic sensors
- scientifically analyzing the sensor and building test cases for analysis
- Testing experience for automotive perception problem
- Experience in weather influence on the sensors

Required tools:
- the students’ notebooks or pc pool lab
- 2x Ultrasonic sensor (Texas Instrument with board)
- Matlab
