Functional Layout Considerations for Designing an On-Board Thin Client System

In recent years, the upgrade cycle for automobiles has become increasingly longer. On the other hand, the cycle of developing and releasing an on-board device continues to become shorter. This poses a problem by making it difficult to upgrade the on-board devices in vehicles, so as to equip them with the latest functions. In order to solve this problem, the authors decided to build and validate a system, while maintaining an architecture where control of almost all of the functions of the on-board device are transferred to a separate mobile device and a network communication center.
