A method of dynamic adjusting a generation frequency of messages in vehicular networks is provided, including: receiving updating requests and emergent degree of the vehicle event, and then determining whether the generation frequency of messages meets the dynamic change of the vehicle, if not satisfied, selecting a different adjustment method according to the event emergent degree. When the event is emergent, its generation frequency can be raised immediately by an interruptive adjustment and to suppress the generation frequency of messages of the others. Conversely, adjusting its generation frequency by a progressive adjustment and reducing the generation frequency of messages of the other lower-priority vehicles. According to the present disclosure, it prevents lower priority messages from occupying the channel overly, and emergency messages with higher priority can be satisfied immediately when it needed.
