What does V2V communication technology mean

Vehicles automatically send information about their movements to other vehicles within a few hundred meters via short-range radio technology (DSRC). The surrounding vehicles use the received information to build a real-time dynamic map. By predicting the travel information of other vehicles, drivers can be warned in advance of collisions, avoiding traffic accidents and effectively relieving congestion.V2V technology uses dedicated short-range communication (DSRC) with a coverage range of up to 300 meters. Compared with traditional radar-detecting V2V communication technology, it reduces the probability of blind spots by displaying real-time signals to show the status of objects that cannot be seen in the field of view. Compared with traditional communication technology, the use of 5.9Hz frequency band for special communication can ensure security and privacy.In 2005, General Motors first introduced V2V information exchange technology. However, with the rapid development of computer technology in recent years, the performance of message transceivers for Vehicle-to-Vehicle Information Exchange technology has been greatly improved and their size has been significantly reduced. In addition, pedestrians and bicyclists can carry the system's equipment with them, effectively increasing pedestrian safety. GM predicts that the widespread use of this advanced technology will greatly reduce the number of injuries and fatalities caused by automobile collisions, thus achieving a more harmonious and safer traffic environment.
