This paper presents a virtual vehicle simulator for testing networked embedded systems. These days a vehicle can include up to one hundred electronic control units. These control units are connected via communication media in order to improve the performance of vehicles. However, it is not an easy process to test electronic control units in real vehicles. Thus, we propose a virtual simulation of a vehicle which is controlled by an embedded network system. The simulator provides the essential requirements necessary to accurately test networked embedded systems. The proposed simulator provides a three-dimensional (3D) modeled virtual vehicle which is controlled by multiple networked embedded systems that transmit information to the simulator via LIN, CAN, and FlexRay communication protocols. This simulator enables us to predict the vehicle’s dynamics and communication problems.

This paper presents the requirements of an automotive gateway for in-vehicle networks. Modern vehicles include several heterogeneous networks such as LIN, CAN, FlexRay, and MOST. The gateway enables seamless communication between heterogeneous networks. The role of a gateway is not complex, but the gateway has the potential to damage the operation of other connected electronic control units and networks. In this paper, we analyze the requirements for the automotive gateway from the viewpoint of hard real-time embedded systems in automotive distributed control systems. We implement the gateway based on these requirements. Finally, we evaluate the performance of the gateway.
