  • Patent number: 9575877
    Abstract: A method for testing control software of a controlled system is disclosed. The method may involve providing control software code data for each of the one or more electronic control units. The method may further involve providing simulation code data for the controlled system. The method may further involve providing verification requirement information data that indicates one or more verification requirement conditions corresponding to a respective control error situation. The method may further involve creating a system model based on the provided simulation code data and the provided control software code data provided for each of the one or more electronic control units. The method may further involve creating an executable program based on the created system model and performing a software verification process on the basis of the executable program.

  • Patent number: 8243609
    Abstract: A method and apparatus for monitoring the operability status of nodes of a communication network determines first node status data at a first node by causing it to diagnose its own status and the status of at least one second node, and to send the first node status data to at least one second node. The first node receives second node status data from at least one second node, and determines node status evaluation data at the first node based on the determined first node status data and the received second node status data.
