When cars can talk to each other wirelessly, they can learn information that a driver can’t see, warn the driver and engage safety features. The ability of cars to communicate wirelessly through Vehicle-to-Vehicle (V2V) communication premieres this year on the Cadillac CTS performance sedan.
Starting with 2017-interim-model-year cars, Cadillac’s V2V-equipped vehicles will lay the groundwork for a connected and safer future. In addition, the Cadillac CTS also offers many communication technologies to connect drivers to their smartphones as well as many advanced safety features.
Cadillac is on the forefront of this technology and began introducing the concept of V2V and Super Cruise as part of its vision for intelligent cars as long ago as 2014. Super Cruise describes Cadillac’s brand of automated driving technology that allows for hands-free driving on the highway — both at speed and in stop-and-go driving.
Cadillac’s V2V solution uses Dedicated Short-Range Communications (DSRC) and GPS that can handle 1,000 messages-per-second from vehicles up to nearly 1,000 feet away. V2V-enabled data alerts drivers of potentially hazardous situations ahead, giving them additional time to react. For example, a Cadillac with V2V may stop for a deer crossing the road ahead. It sends a signal out to warn other cars with V2V. The use of V2V is especially useful to drivers whose view is obscured of dangers en route.
“When there is low visibility such as rain, snow, or fog, and a driver receives a warning, V2V has the potential to save lives and thousands of dollars in damages,” said Cadillac spokesman Steve Martin.
Common hazardous scenarios that prompt alerts are hard braking, slippery conditions, and disabled vehicles. Through the next-generation Cadillac User Experience (CUE) infotainment system, drivers can customize alerts to show in the instrument cluster and on the available head-up display, says Martin.
Only vehicles equipped with compatible V2V systems can communicate with one another. Multiple V2V-equipped vehicles will create an ad hoc wireless network that allows for the transfer of information without relying on sight lines, good weather conditions, or cellular coverage.
The V2V technology on the 2017 CTS operates on the 5.9 GHz spectrum allocated by the Federal Communications Commission. NHTSA stated in its V2V readiness report that V2V-equipped vehicles can “perceive some threats sooner than sensors, cameras, or radar can, and warn their drivers accordingly.”
“We’re putting our stake in the ground to support V2V DSRC and we hope that other automakers will follow,” said Martin who notes that Cadillac as company embodies its motto, “We drive the world forward and dare greatly.”
Martin says that Cadillac chose DSRC because of its security measures and the car does not store any data that can identify the driver. Some automakers are looking at wireless networks such as 4G LTE; however, he says those networks can lack coverage in some areas.
V2V will likely be available on other General Motors vehicles in the future. In the meantime, Martin says that Super Cruise will roll out sometime later in 2017.
V2V will be included as a standard feature on the 2017 CTS in the U.S. and Canada and complements a suite of already available driver awareness and assistive active safety features such as adaptive cruise control with full-speed range, automatic front and rear braking, forward collision mitigation, lane keep assist, and rear cross traffic alert.
In 2016, Cadillac pioneered the world’s first rear camera mirror, increasing the driver’s rearward vision by approximately 300 percent. The camera shows what is behind the car without the obstruction of rear posts, passengers, or packages in the mirror’s field of vision, notes Martin.
The Cadillac CTS is packed with user-friendly technology that connects to users to smartphones, Wi-Fi, navigation, and roadside assistance.
Cadillac recently revamped its next-generation CUE system with a personalized, intuitive interface. The built-in OnStar 4G LTE enables an active wireless connection to the vehicle that — with customer consent — will allow Cadillac to remotely update features such as navigation and the newly launched Collection app store, after vehicle purchase.
The available 4GLTE Wi-Fi hotspot in the Cadillac CTS allows passengers to connect up to seven compatible mobile devices, smartphones, and tablets to high-speed wireless internet, while Bluetooth connectivity supports the concurrent use of two compatible phones. Meanwhile, OnStar continues to offer navigation, roadside assistance, and emergency response services.
