Android Platform Based on Vehicle Embedded Data Stream Processing

In the automotive field, intelligent control systems and information services using vehicle data are rapidly expanding. However, there is no software architecture to handle sensor data in vehicles and their surrounding efficiently. To solve these problems, we have researched and developed data centric software architecture for automotive systems. We have also developed a data-stream management system for automotive embedded system (eDSMS) as data centric software architecture. In this paper, we design eDSMS in the Android platform by extending the in-vehicle eDSMS to provide drivers and users with services on the basis of the embedded data processing of eDSMS in a vehicle. We create a class that manages stream processing in eDSMS in the Android platform and a communication method between Android applications and eDSMS in the Android platform with the stream. Application program interfaces for eDSMS in the Android platform and a sample program using the APIs are presented.
