Vehicular Management System
Nowadays, a vehicle contains many electronic devices connected with multiple communication protocols in order to meet the needs of customers and improve the performance of the vehicle. In addition, the growing need to access information in remote mobile environments has sparked interests in telematics systems. Telematics systems combine mobile computing and telecommunications technologies to provide computing facilities for road-vehicles. It enables drivers (owners of vehicles) to be provided by a wide diversity of services. As the number of electronic devices in automotive systems increase, vehicular management services are being more requested. However, telematics services, in general, focus in Infotainment such as video, audio, navigator, and the sophisticated multi-media services. In addition, traditional vehicular management systems (VMS) have the limitation that it cannot control and access the whole automotive system. In order to overcome these limitations and provide the more advanced services, we need to access to the electronic control units (ECUs) used to control automotive components such as door control, smart key control, head-light control and so on. However, the external devices are hard to access whole automotive systems and make it difficult to collect the all of status information of the vehicle because of too many ECUs with the different communication protocol interfaces. Thus, the unified gateway is necessary in order to integrate with the different protocols. The architecture of in-vehicle network (IVN) is the general configuration for constructing the networked control system in a vehicle. It will be established in the future vehicles gradually. The future vehicles will contain several networks with different communication protocols, such as local inter-connect network (LIN), controller area network (CAN) and FlexRay networks, for the purpose of reducing cost and improving the performance of a vehicle. Therefore we propose a VMS included a gateway for IVNs which can access whole automotive system. The developed gateway not only supports LIN, CAN and Flexray but also wireless communication interface (e.g. CDMA). Thus, the proposed VMS provides the interfaces that can control a vehicle and collect the information from the whole automotive system. VMS makes available several useful and convenient functions that can allow the driver to manage a vehicle easily such as light management, oil management, and other parts management. The main contributions of this paper include the proposed unified gateway and the enhanced vehicular management system.
