Toyota connects navigation systems to the cloud By Christoph Hammerschmidt a new traffic information system for Toyota drivers blends a variety of parameters including vehicle location data, current speed, road conditions and even disasters. The concurrent utilization of these data helps optimizing routes and travel times. The “Big Data Traffic Information Service” gathers traffic flow data from several telematics services. These swarm data are collected, stored and enriched by contributed data from specific commercial user groups such as emergency services or forward agencies. From all these data a live traffic flow map is generated and made accessible to users. The purpose of the service is to improve overall traffic flow and enable trade-specific navigation services. In addition, the service is designed to enable faster emergency services in the case of catastrophic events such as earthquakes. Besides Toyota drivers, also subscribers of Toyota’s G-BOK telematics service for smartphones can access these data and use them to optimize their travel route. This cloud-based service allows the use of traffic information gathered by Toyota and provides information on routes and traffic density on specific trajectories. All data are fed into the in-car navigation systems, but they also can be accessed through computers, tablets or smartphones. The service displays a great variety of additional information from the authorities; it also displays the location of emergency services and vehicles. Users can add their own data. Information about facilities owned or operated by local governments and businesses and locations of commercial vehicles can be shown on the map, while information and images can be submitted by users via smartphones. In disaster situations, information about evacuation sites, shelters, and other facilities can be shown, with the location of rescuers (equipped with smartphones) and emergency and relief vehicles also indicated on the map. To facilitate damage assessment and relief efforts during times of emergency, rescue personnel can submit damage information and make relief requests via smartphone, with this information being shown along with T-Probe traffic information, route history, and hazard maps provided by local governments. At other times, the service can be used for traffic and logistics systems. Suitable processing of T-Probe traffic information enables map-based route planning for effective guidance to multiple destinations, along with location tracking and travel history management. The service will be available initially in Japan, Toyota said. Intel joins A4WP wireless charging group By Peter Clarke intel has joined the alliance for Wireless Power (A4WP) consortium and taken a seat on the board of directors along with Broadcom, Gill Industries, IDT, Qualcomm, Samsung Electronics and Samsung Electro-Mechanics. The move will put weight behind A4WP which is a rival standards organization to the Wireless Power Consortium (WPC), seeking to provide wireless charging for portable consumer electronics devices, including, smartphones, tablet, netbook and laptop computers. WPC was the first to market and claims as many as 8.5 million products have shipped using its Qi technology, some based on chips announced last fall by Texas Instruments. Intel demonstrated its own technology. A4WP, which specifies the use of magnetic resonance technology, is capable of simultaneous charging of multiples devices and the flexible positioning of devices and a charging platter. “Intel believes the A4WP specification, particularly the use of near field magnetic resonance technology, can provide a compelling consumer experience and enable new usage models that make device charging almost automatic,” said Navin Shenoy, general manager of the mobile client platform division at Intel, in a statement issued by A4WP. The A4WP mission includes development of industry specifications for submission to national and international standards development organizations, management of an A4WP certification program, including consumer-recognizable certification logo and the coordination with national and international regulatory agencies regarding policy and compliance. www.electronics-eetimes.com Electronic Engineering Times Europe July/August 2013 15
