Internavi
Internavi is a vehicle telematics service offered by the Honda Motor Company to drivers in Japan. In the United States, the service is known as HondaLink, or sometimes MyLink. It provides mobile connectivity for on-demand traffic information services and internet provided maps displayed inside selected Honda vehicles. The service began August 1997 and was first offered in the 1998 Honda Accord and the Honda Torneo sold only in Japan starting July 1998. The service received a revision to services offered October 2002, adding traffic information delivery capabilities for subscribers to the Internavi Premium Club, and was optional on most Honda vehicles sold in Japan. VICS was integrated into the service starting September 2003. Membership in the service has steadily grown to exceed 5 million subscribers as of March 2007.
The subscription service replaces the need to periodically update in-car navigation systems that use CD, or DVD installed maps that must be updated with the latest information. The maps are sent by internet connections established through the drivers cellphone with a data download plan associated with the cellphone.
The service is available without having to purchase a Honda vehicle installed with the technology; The Internavi LINC is available at both the Apple App Store and Android Market and can be installed on compatible mobile devices.
One of the features offered is the ability to overlay weather information on the in-car map screen in 3D. Route guidance is provided in conjunction with VICS provided information so as to display a large weather disturbance approaching, such as a snow storm or typhoon, allowing drivers to take alternate routes.
Internavi (with VICS)
The following is a description of the various elements that comprise Honda's "Internavi" information service, including integration of the Japanese governments nationally offered service VICS, or Vehicle Information and Communication SystemOn-demand VICS
The technology is dependent on the user's cell phone service, and uses the data download plan associated with the users account. Once connected, one of the services available is route calculations towards a specific destination. The navigation technology interface connects to the server automatically at the Internavi Information Center, calculations and route planning is then determined towards establishing the quickest route towards the selected destination. The identified route also takes into consideration all currently known traffic and local transportation issues that may affect the plotted course from the VICS center, which is updated every five minutes based on reports from various sources. As travel begins towards the destination, any updated conditions areinstantly relayed to the vehicle in real time. If cellphone service connection is lost, information will be updated as the connection is reestablished. Under normal navigation conditions, FM-multiplex broadcast VICS will prompt when specific conditions become aware, such as traffic congestion. The plotted course is then modified based on new information received to adjust travel time information, to include inter-city motorway links. Information received to vehicles installed with Internavi technology are installed with an antenna externally installed. Information is also transmitted by transmitter towers located throughout Japan, identified with a "Beacon Light" located on main urban roads. In this manner vehicles with Internavi receive information from both the "beacon light" towers and by individual cellphones paired up' with vehicles, providing highly accurate information in real time.
Internavi "floating car" system
As the vehicle travels, either on a planned destination or unguided autonomous driving, the vehicle installed with Internavi records the vehicle's GPS position and speed onto the vehicle's hard disk drive, and periodically updates to the Internavi Center Information Server. This autonomous information is then retransmitted towards other users, notifying of road conditions. Vehicles installed with previous internal maps utilizing a DVD are not given updated traffic conditions. Speed conditions are then displayed in three colors—red, orange and blue—to signify traffic congestion conditions, overlaid with updated VICS known conditions. This feature can be deactivated by the driver if position and speed of the individual vehicle does not want to be transmitted, however by doing so, road conditions can not be shared unless the tracking system is activated. Reports will then be limited to VICS information only. Road conditions can be specifically defined towards individual lane conditions, as opposed to general road conditions, such as to identify a traffic incident in a particular lane. As the information is stored by various contributing vehicles, congestion prediction can also be provided. Road conditions are transmitted by the VICS system, however, Internavi provides additional and more specific road and traffic conditions based on individual lane conditions provided by vehicles recording Internavi "floating car" conditions, specifying which lane and the direction of the road itself. Internavi supporting traffic information is transmitted by individual driver's cell phones, and if cellphone conditions are disrupted, the information is recorded onto the vehicles HDD, so that when cellphone reception is restored, all recorded information is then transmitted and updates are sent towards participating vehicles.Parking selection function
Internavi participating vehicles also benefit from available parking spaces, whether it be on the street or in parking structures, public or private parking, from Internavi-equipped vehicles having made available a parking space. The space is also defined by the size of the leaving vehicle so that vehicles looking for a parking space can be reasonably confident the vacant space will accommodate the arriving vehicle.Internavi Weather Features
As of October 2004, inclement weather conditions are overlaid onto the Internavi display map when the orientation of the map is displayed in 3D. This ability displays weather fronts as they approach the vehicles current position.Information and CDDB music downloads
When playing a CD, the Internavi operating system provides the ability to save a particular song or the entire contents of the CD onto the hard disk within the vehicle. Information about the CD is then provided by Gracenote.Other Services
Map Update Service
The HDD map data is automatically updated for 24 months from registration, or up to 3 times map data on DVD sourced information before the first Japanese Government mandated vehicle inspection. After the time period has lapsed, map data updating is a supplementary service.If the vehicle has been sent to Honda dealers for repair, the HDD map data is completely upgraded to the most current data available. Any music files stored in the HDD will be safeguarded to prevent accidental deletion.
