The growing mobility of people and goods incurs high societal costs: traffic congestion, fatalities and injuries
In the past decade, numerous efforts have sought to mitigate these problems and produced solutions ,like information on traffic and hazardous situations are broadcast via the FM radio ; variable message signs, spaced a few kilometers apart or at strategic points (e.g., merging highways, tunnels, bridges) along freeways, warn drivers about changing conditions; electronic toll systems collect fees with reduced or almost no disruption of traffic flow.
At the same time, vehicles have increasingly effective driver assistance and protection mechanisms. Various on-board controls and information sources allow the driver to customize driving experience and remain up to date on the vehicle status.
Vehicle Communication System
In automotive terms, it refers to any system that collects, processes, and transmits data: GPS systems, remote vehicle diagnostics, and automatic crash notifications, for example. Most important, through the seamless combination of Wi-Fi, DSRC, and LTE, we’re setting the stage for the next generation of connected cars by delivering a superior in-car connected car platform for all types of vehicle communications.
With V2X—the umbrella term for V2V, V2I, V2P, and V2C—communications, vehicles share information with each other and their surroundings to make driving safer and more efficient:
V2V (Vehicle-to-Vehicle): Communication technologies like DSRC support safety systems with non-line-of-sight and latency-sensitive collision avoidance capabilities that benefits drivers, passengers, and everyone who shares the road.
- Collision avoidance safety systems
- Support for autonomous driving
V2I (Vehicle-to-Infrastructure): Connected car-to-infrastructure communications offer a variety of applications, including safety, on-the-road information, and interactivity.
- Road related information/warnings (signage)
- Traffic signal phase timing (red/green phases for emissions control and reduced congestion)
V2P (Vehicle-to-Pedestrian): Both drivers and pedestrians can receive warnings to prevent anticipated projected collisions. Pedestrians receive alerts via smartphone applications or through connected wearable devices.
V2C (Vehicle-to-Cloud): For cloud-based security, information, entertainment, and connected car services that make driving both more efficient and enjoyable.
- Firmware updates
- Security authentication
- Parking spot finder
- Real-time traffic and routing
- Reservations, reviews and connected car services
The benefits to having autonomous and semi-autonomous vehicles—safer roads, greater fuel efficiency, city-wide traffic management, and reduced emissions—will be transformative, and advanced connectivity is a vital component of that reality.
