Problems solved by technology

If the exterior of the vehicle has been severely damaged in an accident, such as a rollover or collision, the vehicle's exterior antenna may not function properly
In this case, emergency call requests may be delayed and the risk of accidents around approaching vehicles may increase

Embodiment Construction

[0038] Reference will now be made in detail to the preferred embodiments of the inventive concept, examples of which are illustrated in the accompanying drawings. The suffix "module" or "unit" used for elements in the following description is given and used together only in consideration of the convenience of preparation of this specification, and has no special meaning or function.

[0039] Hereinafter, although one embodiment of the inventive concept shows all combined elements, the embodiment of the inventive concept is not limited thereto. That is, one or more elements may be selectively used within the scope of the inventive concept. Further, all elements may be realized by independent hardware respectively, or some of all elements may be selectively combined and thereby realized by a computer program having a program module that executes the functions of the combined elements in a plurality of pieces of hardware. Codes and code segments constituting the computer program...

Abstract

A method for controlling antennas in a vehicle having an external antenna and an internal antenna includes triggering an eCall service function upon sensing an accident occurrence event, measuring the quality of one or more wireless signals received through the external antenna, comparing the measured quality of the wireless signals with a reference quality value, and selecting one of the external antenna and the internal antenna to be used in the eCall service function based on the results of the step of comparing the measured quality of the wireless signals with the reference quality value. A system of emergency communication of the vehicle is also provided.

Description

technical field [0001] The inventive concept relates to a method for controlling an antenna in a vehicle communication system, and more particularly to such a method for controlling an antenna in which a vehicle equipped with an automatic emergency call system and devices therefor When various emergency situations occur in the vehicle, the optimal antenna is selected through self-diagnosis, and the emergency call service is provided more quickly and safely. Background technique [0002] The recent rapid development of information technology affects the automobile industry, and various information technologies are incorporated into vehicles. [0003] An automatic emergency call system (also simply referred to as an "eCall system") is an emergency call system operated when a serious traffic accident occurs. When a vehicle equipped with the eCall system senses a serious accident, the vehicle transmits a designated warning message or an emergency call message to the nearest veh...
