Telematics Gateway and Power Method for Electric Vehicles

By: Chang, Yu-Xin Guo and Mu-Der

Abstract and Excerpt from: Man and Cybernetics (SMC), 2011 International Conference on

Abstract- on the characteristics of electric vehicles this paper proposes a framework utilizing the Controller Network (CAN) bus technology, connector and the existing telematics systems to construct a novel gateway for EV. Vehicle gateway has been applied to telematics systems for many years but not to EV. The framework of telematics gateway a three layers’ architecture, the physical layer, data layer, and application layer.

The gateway needs to resolve two One is to simplify the framework of EV gateway and the other is to ensure the application for power saving and location service (LBS). Using the of telematics gateway, the entire network can meet different scenarios for EV.

The evolution of telematics can be divided three generations. The first vehicle to zero (V2Z) is a and independent telematics service The second generation: vehicle to (V2I) is now the popular telematics system in the world. The third vehicle to extension (V2X) includes V2V, V2I and V2P (vehicle to is the developing telematics for many applications but under the limitation of network bandwidth. The existing server systems consist of applications, a short messaging center (SMSC) connection the related servers’ connection HTTP, and TCP/IP.

The server applications provide applications in a vehicle with services such as emergency remote door unlocking, and vehicle diagnostic service the wireless application protocol gateway in a mobile network. of the existing telematics services been dependently developed and on specific systems of a mobile This creates a situation services may not be available on other networks.

Also, telematics are used only for engine

Energy and environment are the two fundamental of the modern world’s sustainable With the development of economy, the of vehicle maintained a rapid growth and the problem of energy and becoming more austere day by Electric motor car has many such as non-polluting, high efficiency, energy diversification, structural parts, and convenient to etc. It is a good way to relieve the and environment problem which more and more serious. In to decrease weight, the electric cars have adopted equipment as much as possible to the traditional mechanical and hydraulic

The increase of electric equipment not decreases the weight of car, but brings forward a higher to the car’s communication system. To CAN bus is the most mature and developable bus It is a serial communicational network can efficiently support distributed and real-time control. Controller Network has many special so that it can be popularly applied in CAN-bus technology SAE J1939 and the nodes through distributed method have been to build an electric motor body network system.

The telematics service system by this article has the advantage of value added applications of saving and location based for EV.

In the telematics service system, gateway interfaces with OSI 7 layer’s protocols including the CAN bus and have been studied and to engine vehicles but not to EV. With the world’s development of green and green ITS, telematics system and EV have become important issues for environmental Therefore, this paper a novel and conceptual framework of gateway for EV using CAN bus, connector and vehicle gateway in the telematics service system.

The proposed framework of telematics establishes a three layers’ namely, the physical layer, link layer, and the application The telematics gateway needs to the conceptual framework of EV gateway In addition, application scenarios of saving and LBS are proposed to verify the of telematics gateway interface.


other value-added application also can be realized on the conceptual of telematics gateway for EV.

The rest of paper is organized as follows. In II, the preliminaries of vehicle gateway and basic telematics gateway for EV are Section III then thoroughly the proposed conceptual framework of gateway.

In Section IV, using proposed of telematics gateway, two application with telematics gateway are and the benefits for EV are verified. Conclusions are drawn in Section V along recommendations for future research.
