For our experimental vehicle, we are in need of the conception and realization of speed measurement. Since this functionality is a matter of safety-critical functionality, the design must be carried out according to IEC61508 (functional safety of electrical/electronic/programmable electronic safety-related systems). The implementation should be done on a microcontroller or/and on a PLD. Furthermore, a connection to the CAN-bus should be created.

On the basis of an exemplary implementation, you will demonstrate how different requirements and rules for safety-critical systems can be implemented. Thereby, the international norm IEC 61508 and the MISRA guidelines will have special relevance.
