Composite terminal installed inside the vehicle.{Composite terminals installed inside the vehicle}

The present invention relates to a composite terminal installed in a vehicle, and more specifically, based on a digital driving recorder that stores driving information secured through a CAN connection and a vehicle interface, an E-call service is possible as well as a video. It also relates to a composite terminal capable of maximizing the space efficiency inside the vehicle while minimizing the economic burden by having a black box function for storing camera data and a high-pass terminal function.

Currently, in developed countries centered on the EU, in the event of a car accident, in order to save valuable lives within the Golden Time,

Research on e-call terminals that automatically detect whether an accident has occurred and notify the emergency response center (PSAP) of the public safety answering point has been conducted.

In recent years, e-Call terminals are required to be installed in Europe in March 2018 for small cars, and in Russia, mandatory installations have already been implemented around small cars.

Therefore, in Korea, various ministries are jointly conducting R&D to decide on the introduction of an emergency rescue system based on vehicle ICT and to induce related standards and necessary technology development and early settlement of related industries. The goal is to develop a system and an e-Call terminal for it and to equip it.

However, e-Call terminals and VSM (Vehicle Status Monitoring) terminals can be additionally installed only for passenger cars or small commercial vehicles.

In the case of transportation vehicles or commercial vehicles (hereinafter referred to as vehicles), such as mid-sized or large-sized freight cars, buses, taxis, etc., the traffic records are analyzed in accordance with "Enforcement Regulations of the Traffic Safety Law" and "Article 29-2 (1)". Depending on the system, a digital tachograph is installed to submit operational information once every six or three months, so that the operational status of the commercial vehicle can be analyzed.

Therefore, in the case of a conventional commercial or transportation vehicle. In addition to the digital driving recorder, the e-Call terminal and the VSM (Vehicle Status Monitoring) terminal must also be installed inside the vehicle, which is an economical burden.

As the space inside the vehicle is forced to be narrowed, and the surroundings of the dashboard are forced to become dirty, there is a danger that a secondary accident may occur due to the above devices when a vehicle accident occurs.

Moreover, since the e-Call terminal and the VSM terminal are not used at all after being installed in a vehicle and before an accident occurs, there is a problem in that it is difficult to check if a failure occurs due to lack of management. In other words, it should be managed steadily in the middle, and this situation is not considered at all.

KR 10-2012-0050023 A KR 10-2015-0137555 A KR 10-1498367 B1

Accordingly, the present invention integrates a digital driving recorder, an e-call terminal and a VSM terminal into one, and in some embodiments, integrates a black box and a high-pass terminal into one terminal.
