Investigation and verification of a new acceleration pedal platform in cars

Sammanfattning

This thesis explores how signals from the Acceleration Pedal Module (APM) are processed by the Electronic Control Unit (ECU) in the New Platform, with a special focus on the SENT protocol, which is not widely understood. The study aims to uncover how the pedal’s position and movement are translated into signals and how these signals can be monitored and verified effectively. A key part of this work is understanding the sensors in the acceleration pedal, including how they measure the pedal position and the speed at which it is pressed, which provides insight into vehicle responsiveness.The research also investigates the tools needed to carry out these analyses, particularly the CANoe software, which is used for testing, development, and monitoring the communication between the APM and ECU. Beyond understanding the current system, the thesis investigates recent advancements in signal processing within the New Platform and how these improvements enhance the accuracy and reliability of the acceleration pedal.Finally, the thesis proposes a practical model for a test rig that can be used in a Hardware-inthe-Loop (HIL) environment. This setup is designed to support the development and testing of APM-related ECU software, ensuring that the acceleration pedal interface performs reliably and efficiently. Overall, the study combines theoretical understanding with practical solutions to improve vehicle performance.
