1. A vehicle-to-X communication system for a vehicle having:

  • a first antenna configured to emit data signals towards a front of the vehicle,second antenna configured to emit data signals towards a rear of the vehicle, anda communication unit, which is connected to the first antenna and the second antenna in order to transmit the data signals via the antennas,wherein the communication unit is designed to;

    transmit a higher proportion of the data signals via the first antenna than via the second antenna when the data is determined to be more relevant to road users in front of the vehicle than to road users behind the vehicle in response to a speed of the vehicle being greater than a first threshold, andtransmit a higher proportion of the data signals via the second antenna than via the first antenna when the data is determined to be more relevant to the road users behind the vehicle than to the road users in front of the vehicle in response to at least one of;

    the speed of the vehicle being less than a second threshold, the data being directed to an incident on the road that the vehicle is traveling on, or braking of the vehicle,wherein the first threshold is the same as the second threshold, or the first threshold is different than the second threshold.
