Kurzfassung englisch:
Despite its age and even though Ethernet is becoming popular, CAN is still widely used in distributed automotive systems. In such applications, a network-wide notion of time is often a prerequisite. However, precision clock synchronization over CAN is difficult to attain, and current approaches use dedicated hardware or proprietary software solutions. On the other hand, there is a standardized synchronization method which was defined by the AUTOSAR development alliance. This paper investigates the achievable precision using a purely software-based implementation of the AUTOSAR method using standard CAN controllers in a typical automotive real-time operating system. Preliminary results show that a precision of around 400 microseconds can be achieved with a fully AUTOSAR-compliant software implementation, and that there are options for further improvement.
