Future Automotive Insurance System based on Telematics Technology

With the proliferation of vehicles and advancement of information technology, the technology of telematics, which provides valuable services to people by collecting and analyzing the information from drivers, vehicles and Telematics environments (e.g. traffic information, road condition, weather information, etc.), has been a hot research area in IT and automotive recently. There are needs for telematics makes more profitable. Telematics based insurance services could be one possible business model. In this paper, we have investigated trends of telematics based insurance services in the industry and discussed required technologies for telematics based insurance services. Finally, we summarized the framework for insurance telematics which we had developed.

Exhibition speaker: Driver-oriented intelligent human-vehicle interaction system

In this paper, we introduce driver-oriented intelligent HVI(Human-Vehicle Interaction) system, which is designed to integrate the interfaces in the vehicle. The proposed HVI system monitors the vehicle, the cell phone, the car navigation system to recognize the drivers primary tasks and secondary tasks. It is estimated the driving workload from the status information, the output information is controlled based on the driving workload. We implemented the proposed HVI system with the vehicle information collector, the HVI cell phone and the HVI car navigation system. In this paper, the structure of the proposed HVI system is described and the implemented system deployment is represented. The proposed HVI system will be extended to be connected other IT devices in the vehicle environment and to estimate the driving workload more exactly.

The Human Vehicle Interface System for Integrating and Managing the In-Vehicle Interactions with IT Devices

Objective: The aim of this study is to investigate the system to integrate and manage the in-vehicle interactions between the drivers and the in-vehicle mobile IT devices. Background: As the mobile IT technology is being used anywhere, the drivers are interacting with the mobile IT device on driving situations. The distraction of the drivers attention causes the car accidents. It is necessary to develop the HVI(Human Vehicle Interface System) to integrate and manage the in-vehicle interactions with IT devices. Method: The HVI System is designed not as the interfacing subject but as the supervising system to monitor the drivers status and support the driver to concentrate on the primary tasks. The HVI system collects the status information of the car and driver and estimate the driving workload. Results: The HVI system controls how to provide the output information based on the driving workload. We implemented the HVI system prototype and applied in the real vehicle with the HVI cell phone and the HVI car navigation system. Conclusion: Depending on the driving situations, the HVI system prevented the information output in dangerous situation and diversified the modality and the intensity of the output information. Application: We will extend the HVI system to be connected the other various IT devices and verity the effectiveness of the system through various experiments.

Multimodal interface for driving-workload optimization

Today, driving convenience has increased greatly owing to the availability of various telematics devices developed recently. However, this convenience often comes at the cost of driving safety. With the aim of achieving a balance between them, we propose a multi-modal interface for optimizing driving workload and describe an efficient design for the interface. To demonstrate the effectiveness of the interface, we use it in a simulator environment resembling real driving situations, designed to allow the interface to detect and analyze states of both the driver and the vehicle in real time. The proposed interface transfers information by optimizing the driving workload such that it within a range appropriate in view of driver safety. In the future, we intend to demonstrate the feasibility of the proposed interface through multiple experiments.

Request Based Telematics Contents Providing System using DMB

This paper describes a system for providing the telematics contents through DMB, according to the requests which are demanded by users. This paper includes the structure of the system which collects the messages requested by users, and makes the list of requests priority, and broadcasts telematics contents through the data channel on DMB. This system enables users to receive the requested telematics contents which are categorized by regions and services. Therefore, the proposed structures help users to receive the distinctive DMB data services. Moreover, the system can reduce the amount of each service data as the service vendors increase the bandwidth of the content requested frequently within the limited bandwidth by collecting and analyzing the requested contents.
