Abstract

The invention relates to a V2X technology fused vehicle emergency call system, which is applied to a vehicle-mounted system provided with a V2X device and an eCall device. The method comprises the following steps that: when the eCall device of the vehicle-mounted system is activated, the vehicle-mounted system judging whether a public network is detected or not; when the public network is searched, the eCall device being connected with the public network, and the eCall device calling outwards through the public network; and when the public network cannot be searched, the current vehicle-mounted system broadcasting a fault data packet of the current vehicle through the V2X device, and forwarding the fault data packet outwards through a far vehicle. The beneficial effects of the method are that the method can achieve the supplement and improvement of the situation that the eCall cannot work because of the PLMN coverage problem, and enables an accident victim to be rescued as timely as possible.
