Reliability Analysis of Wireless Automotive Applications with Transceiver Redundancy:Developing a Fail Operational System for ecar using wireless cont

Masters Thesis from the year 2014 in the subject Engineering - Automotive Engineering, grade: 1.7, University of Applied Sciences Rosenheim (University of Applied Science), course: Electrotech, language: English, abstract: In this thesis, the Failure Mode and Effect Analysis (FMEA) methodology is implemented for failure analysis in wireless automotive systems. Reliability analysis is done by using Reliability Block Diagrams (RBD). These analyses are performed to develop redundant systems. The main focus of this thesis is to make the system behavior fail-operation using wireless technology. The implementation of algorithms and protocol design has been done with an MSPEXP430 board and a CC2520 transceiver to detect single point failures. The implementations were then tested to detect different failure levels successfully. In this modern age, a car has different functionalities and facilities. The implementation is done by using different actuators, sensors and Electronics Control Units (ECUs). Due to the high complexity of wiring and addition of weight to a car, controlling and maintaining these devices is difficult. As a solution for these complexities and the problem of weight growth, wireless technology has been used with the TDMA method. The approach for replacing wire by wireless technology may, however, not be secure and reliable.
