Expressed in simple terms, car-to-x communication is the "radio-based exchange of information between vehicles, as well as between vehicles and traffic infrastructure", explains Dr. Christian Weiß, responsible for car-to-x communication at Mercedes-Benz Development. "This has the major advantage that we are also able to obtain information from points far outside the driver's field of vision, which is not the case with conventional sensors“. This information provides the basis for a number of new assistance functions which complement the existing systems. "Car-to-x communication helps us let the driver know of hazardous situations early on. For example, we can warn of wrong-way drivers, but also of the end of a tailback which we are approaching, of emergency vehicles approaching from behind, or from the side at a junction". The safety network originates from a simple principle: every vehicle with car-to-x technology can simultaneously and autonomously receive and send warnings.
