Problems solved by technology

[0008] However, existing eCall systems may not be able to monitor the main battery voltage when the main battery is disconnected from the vehicle, making it impossible for the user to manually operate or test the eCall system while the vehicle is off
[0009] Therefore, the existing eCall system does not prevent the discharge of the backup battery during the transportation process before the vehicle is sold
As a result, the backup battery may need to be replaced before the vehicle is delivered to the customer, and the eCall system may not be operational in the event of an accident prior to the replacement of the backup battery

Embodiment Construction

[0033] Hereinafter, the present invention will be described to be performed by those having ordinary skill in the art to which the present invention pertains.

[0034] The purpose of the invention is to prevent the auxiliary battery (spare battery) embedded in the emergency call (eCall) system from operating for a long period of time when the vehicle is transported to the sales area in which the main battery is separated from the vehicle after its production . Therefore, the present invention can operate the backup battery when the vehicle is delivered to the sales area to prevent the backup battery from being discharged unnecessarily, and thus, the backup battery does not work prematurely.

[0035] like figure 1 As shown, according to an exemplary embodiment of the present invention, a device for preventing the discharge of a backup battery of an eCall system of a vehicle includes a global positioning system (GPS) 10, a microcomputer 20, a sales area information memory 30, a...

Abstract

A device for preventing an eCall system backup battery for a vehicle from discharging is provided. The device includes a GPS configured to provide current position information of the vehicle in which an eCall system is mounted. A sales area information storage is configured to form and store the GPS information on all sales areas as a sales area information database. A microcomputer is configured to determine whether the vehicle is located within a sales area which is a final destination by using the information acquired from the GPS module and the sales area information storage and to control whether the backup battery operates depending on the determination result. A power supply manager is configured to select and manage any one of a main battery and the backup battery as supply power of the eCall system by a control of the microcomputer.

Description

technical field [0001] The present invention relates to an apparatus and method for preventing discharge of an emergency call (eCall) system backup battery of a vehicle. More particularly, the present invention relates to an apparatus and method for preventing discharge of an eCall system backup battery of a vehicle so as to operate the eCall system while the vehicle's main battery is discharged. Background technique [0002] An emergency call (eCall) system senses a collision when a car accident occurs, and automatically transmits condition information including location information of the car accident to a competent authority through an emergency call, thereby shortening a response time to the accident. [0003] When the eCall system receives the airbag deployment signal from the airbag control unit (ACU) in the event of an accident, it will automatically call the relevant center and report the accident to the relevant center. The eCall system has a mobile communication m...
