Wireless communication between vehicles may permit position information about one vehicle to be communicated directly to another vehicle. Such an information exchange between vehicles may increase the awareness of an operator of a vehicle to other vehicles in the surrounding environment and may help a vehicle operator operate the vehicle more safely. Vehicles may share through the use of wireless communications position, direction, speed, or other information, such as the deployment of safety devices or the presence of particular types of vehicles (e.g., an emergency vehicle or school bus). The vehicle that receives a wireless communication compares the position, direction, and speed of incoming information from another vehicle to the vehicle~s own speed, direction, and postion to determine whether action is required. The action taken by the vehicle may include providing general or specific warnings to the operator of the vehicle or, in some cases, taking direct action, such as turning off cruise control, applying brakes, or deploying traction control.

La communication radio entre des véhicules peut permettre de communiquer directement à un autre véhicule l'information de position concernant un premier véhicule. Cet échange d'information entre ces véhicules peut augmenter la conscience du conducteur de la présence d'autres véhicules à proximité et aider le conducteur à conduire avec davantage de sécurité. Les véhicules peuvent partager par l'intermédiaire des communications radio, des informations concernant la position, la vitesse, la direction d'un véhicule, ou d'autres informations, telles que le déploiement de dispositifs de sécurité ou la présence de types définis de véhicules, par exemple, véhicule d'urgence ou bus scolaire. Le véhicule recevant la communication radio compare les informations reçues concernant la position, la direction et la vitesse de l'autre véhicule, à sa propre vitesse, direction ou position afin de déterminer l'action à prendre. Cette action peut consister en des avertissements généraux ou spécifiques au conducteur du véhicule ou, dans quelques cas, en une action directe, telle que couper le contact, freiner ou exercer une traction.
