Cadillac introduces Vehicle-to-Vehicle (V2V) communications this month in the CTS performance sedan, beginning with 2017 cars in production now. V2V-equipped vehicles share information that can be used to alert drivers to upcoming potential hazards, laying the groundwork for a connected future.
Cadillac’s V2V solution uses Dedicated Short-Range Communications (DSRC) and GPS and can handle 1,000 messages per second from vehicles up to nearly 1,000 feet away. For example, when a car approaches an urban intersection, the technology scans the vicinity for other vehicles and tracks their positions, directions and speeds, warning the driver of potential hazards that might otherwise be invisible.
V2V-enabled data alerts drivers of potentially hazardous situations ahead, giving them additional time to react. Common hazardous scenarios that prompt alerts are hard braking, slippery conditions and disabled vehicles. Through the next-generation Cadillac infotainment system, drivers can customize alerts to show in the instrument cluster and available head-up display.
Only vehicles equipped with compatible V2V systems communicate with one another. Multiple V2V-equipped vehicles create an ad hoc wireless network that allows for the transfer of information without relying on sight lines, good weather conditions or cellular coverage.
