Vehicle to Vehicle

GM vehicles equipped with vehicle-to-vehicle technology can detect the position and movement of other vehicles around them. Additionally, other vehicles know where you are, too – whether it is in blind spots, stopped ahead on the highway but hidden from view, around a blind corner or blocked by other vehicles.

With this “sixth sense” they can anticipate where other vehicles are, up to a quarter of a mile away and can react to potentially hazardous driving situations and warn the driver with chimes, visual icons and seat vibrations. If the driver doesn’t respond to the alerts, the vehicle can bring itself to a safe stop, avoiding a collision.

In addition, GM’s V2V technology can warn the driver when vehicles ahead, regardless of lane, are stopped or traveling much slower or a vehicle ahead brakes hard, allowing the driver to brake or change lanes as needed. It also can use rear lights to warn the other driver when the approaching vehicle is moving very quickly and a rear-end collision is imminent.

GM’s unique advantage is in its ability to leverage or enhance existing driver assist systems such as OnStar and StabiliTrak to deliver solutions more quickly and cost effectively. The technology exists today and could be on vehicles in 5 to 10 years.

How It Works

Today, vehicles are equipped with multiple safety sensors, including a long range scanning sensor for adaptive cruise control, forward vision sensors for object detection, mid-range blind spot detection sensors and long-range lane change assist sensors.

GM’s vehicle-to-vehicle (V2V) communication combines a simple antenna, a computer chip, and GPS (Global Positioning System) technology that allows vehicles to communicate with each other. Equipped vehicles can detect other vehicles up to a quarter mile away beyond the line of sight and then can communicate potentially dangerous situations. One advisory sensor has the capability of providing all-around instantaneous traffic intelligence.

This promises a better and significantly less-costly way of sensing other vehicles on or off the road.
