This paper presents the worst case network situation and the analyzed result for timing test on real embedded system. Timing is critical fact in a specific network. As the needs that vehicle is more intelligence, electrical components of vehicle are more enhanced and complicated. The number of electronic control units (ECUs) which are set up at vehicle is significantly increased. Therefore there is...
This paper describes a practical training course for engineering students on embedded systems that are based on electronic control units (ECU) that use the Freescale HCS12 microcontroller. An evaluation board was designed as a single platform for academic purposes and it was implemented with a Freescale HCS12 microcontroller, sensors, a motor, an LED module, and communication modules. Among many microcontrollers,...
As the complexity of automotive networks systems increased, network management mechanisms becoming more important. Although OSEK/VDX includes network management (NM), it is too expensive to use in all ECUs. Since some electronic control units (ECUs) provide only simple functionality, they do not need to use the whole range of OSEK/VDX functions. In this case, OSEK/VDX causes unnecessary overhead....
