Adaptive navigation system with artificial intelligence

Abstract: A vehicle navigation system that is capable of learning user habits/preferences, mistakes in a digital map database, and new roads that may have been added or constructed after release of the digital map database is disclosed. The vehicle navigation system monitors a driver's habits and updates a database to thereby cause the vehicle navigation system to have a preference for the driver's habits. The vehicle navigation system may also monitor the geographic position of the vehicle and allow the driver to update or change data contained in the digital map database if an error exists. The vehicle navigation system is also capable of learning new roads that exist that are not included in the road network map of the digital map database and is also capable of adding these new roads to the digital map database.

Using RFID for Accurate Positioning

Abstract: In Korea, telematics is regarded as the technology to enhance and make everyday-driving experience more comfortable and safer. An essential part of the telematics is navigation and it is mainly based on GPS as the choice of positioning technology. The accuracy of GPS, however, is approximately ten to twenty meters. Combining with map-matching technologies, most navigation systems guide drivers with a best effort manner. In addition to telematics, RFID (Radio Frequency Identification) is an old but newly emerged technology. In this paper, we incorporate RFID technology into a navigation system to improve the accuracy. The skeleton of the idea is as follows: install RFID tags on roads in a certain way, store very accurate location information along with other necessary information in the tags, add an RFID reader module to the navigation system, and use this new location information along with GPS and a gyroscope to produce highly accurate location information. With this scheme, the accuracy of positioning can be dramatically improved, especially in tunnels and in downtown areas. Preliminary results show that this idea is feasible.

Control of a Wheelchair in an Indoor Environment Based on a Brain–Computer Interface and Automated Navigation

Abstract: The concept of controlling a wheelchair using brain signals is promising. However, the continuous control of a wheelchair based on unstable and noisy electroencephalogram signals is unreliable and generates a significant mental burden for the user. A feasible solution is to integrate a brain–computer interface (BCI) with automated navigation techniques. This paper presents a brain-controlled intelligent wheelchair with the capability of automatic navigation. Using an autonomous navigation system, candidate destinations and waypoints are automatically generated based on the existing environment. The user selects a destination using a motor imagery (MI)-based or P300-based BCI. According to the determined destination, the navigation system plans a short and safe path and navigates the wheelchair to the destination. During the movement of the wheelchair, the user can issue a stop command with the BCI. Using our system, the mental burden of the user can be substantially alleviated. Furthermore, our system can adapt to changes in the environment. Two experiments based on MI and P300 were conducted to demonstrate the effectiveness of our system.

Method and system for finding intermediate destinations with a navigation system

Abstract: A navigation system includes a feature that allows a user to specify a type of point of interest at which the user wishes to make an intermediate stop while on route to a final destination. The feature identifies for the user one point of interest of the specified type at which an intermediate stop can be made while on route to the final destination, wherein a route to the final destination that includes an intermediate stop at the one point of interest takes less time than routes to the final destination that make an intermediate stop at other points of interest of the specified type.

Navigation system for an automotive vehicle

Abstract: A navigation system for an automotive vehicle designed to display a road map image around the vehicle in correlation with the current position of the automotive vehicle. The navigation system is adapted to determine a best navigation route to a selected destination on the basis on the approximated time necessary to travel such a navigation route in correspondence to its travel length and speed rate.
