Imagine the possibilities if instead of the car simply being a passive receiver of information, it was actually an active information source. With IEEE 802.11p technology, the dedicated Wi-Fi standard supporting Intelligent Transportation Systems (ITS) applications, that is exactly what is possible. With key information being passed seamlessly between vehicles over 802.11p safety on roads can be dramatically improved through features such as forward hazard warning.
802.11p will improve Advanced Driver Assistance Systems, as it can work at longer distances and even in non-line-of-sight conditions. This provides additional, valuable information that other sensors like radar and cameras usually can’t provide. Of course securing wireless communication will be key in preventing manipulation or tampering of the systems.
Data flows around us every day, especially when we are on the move. Combining the potential of IEEE 802.11p (the dedicated Wi-Fi standard supporting Intelligent Transportation Systems (ITS) applications), GPS and GSM technologies in the car, lets us tap into that data while we are on the road. From relatively simple forward hazard warning to cooperative intersection safety systems, economically viable options to actively control and manage traffic congestion are now possible. 802.11p provides a separate service channel to facilitate new services independently from the safety oriented car-to-car communications.
Of course standard Wi-Fi can be used to synchronize data when the car is parked. Letting drivers sync data with their car when at home or communicating with the garage maintainence system, and potentially even connecting to car external hotspots.
Providing highly convenient functionality, remote car management uses the car key to store vehicle information. When getting in and leaving the car, the key is automatically updated with a variety of vehicle data. The data can range from performance status and service data to the vehicle's GPS coordinates.
Now the NFC-enabled key can be used remotely to transfer data to a PC for various operations – such as checking the car's status at home, self-diagnosis or checking service data with the garage. Alternatively plan a route from the comfort of your home and link it to your key – no more typing the destination into your GPS system before starting your journey. Combined with an NFC-enabled phone, it could even help you locate where your car is parked.
On July 6th 2011 the Region of Eindhoven announced a real-time car monitoring pilot involving 300 cars with NXP, in partnership with IBM, NavTeq, Tass, Beijer Automotive and the University of Eindhoven. The cars will drive with an On Board Unit that connects to the in-car CAN-bus and sends real-time data to a back office via a mobile data connection. Once processed this data will provide road authorities and drivers with better information on local road conditions, and allows fleet managers to monitor their vehicles.
Broadcast reception in the car is an important link to the outside world. Next to analog AM/FM, more and more digital radio standards are emerging around the globe. They complement analog radio with a wide variety of audio services, as well as new data services offering more detailed traffic information, images and slideshows. It also offers the possibilities of receiving emergency warnings, news snippets, weather forecasts and many more value added services besides high quality audio content.
Different digital radio standards are being introduced worldwide requiring car OEMs to offer a variety of broadcast reception systems for the different markets. Examples are HD Radio for North America, DAB(+)/T-DMB for Europe, Australia and parts of Asia, and DRM for India. To reduce the inherent cost of ownership of these complex systems, the car infotainment industry is looking for software defined radio solutions that support multiple broadcast standards with a single chip. NXP is the global number one supplier in car entertainment solutions which offers best-in-class software defined radio solutions.
Take your personal settings with you from car to car using an NFC-enabled device such as a car key or mobile phone. Settings can include driving position, favourite radio stations, navigation options, MP3 library, cockpit design, etc. As you approach or enter the car, your personal settings are automatically downloaded.
For private cars, each user can have their own personalized car key, while a mobile phone containing your data is ideal for rental cars or when in a car sharing scheme. You can also use your NFC-enabled device remotely with a PC, allowing you to change settings and download new features in the comfort of your home.
