Abstract

The invention relates to a vehicle-mounted system and a communication method thereof. The vehicle-mounted system comprises a first unit, a second unit and a third unit, wherein the first unit is used for generating a wake-up signal by confirming a roadside device with a server according to a received trigger signal; and the second unit is used for being awakened according to the received awakening signal so as to execute communication operation with the roadside device. According to the vehicle-mounted system, after the trigger signal sent by the trigger source is obtained, the trigger source is confirmed to be the effective roadside device through the server so as to send the awakening signal to awaken the second unit, so that the second unit is awakened according to needs, abnormal awakening of the second unit is avoided, and the problem of rapid power consumption is solved.
