Abstract
The present invention discloses a dark current reduction device and method. A dark current reduction device according to an aspect of the present invention includes a main micom that controls functions of the vehicle body control module, except for a security indicator light control, and does not operate when the vehicle is turned off; And operating in a sleep mode even when the vehicle is turned off, performing the security indicator light control, and detecting a user input as an interrupt, operating the main micom to correspond to the user input by the main micom. And a sub micom for executing a function.
Description
The present invention relates to a vehicle body control module, and more particularly, to a dark current reduction device and method that can reduce the dark current required when starting off.
In general, when the vehicle is stopped, the vehicle stops the flow of current from the battery to various accessory devices such as the starter and the radio, but the battery current is continuously supplied to a device such as a controller or a current for immediate start-up. do. This current is called dark current.
The dark current reduction system is applied to a conventional body control module, and the microcomputer of the dark current reduction system detects whether a user input is input even in a ignition off state, and locks the car door using a remote wireless door device (RKE). Lock / Unlock and Security Indicator operation were controlled. In this case, however, the microcomputer operated in the normal mode consumed a lot of power.
To improve this, another conventional dark current reduction system detects whether a user input is input at start-up and has a separate input IC for notifying the microcomputer, and the microcomputer operates in the pseudo stop mode while locking the car door. Controlled lock / unlock and security indicators. However, in recent years, the dark current requirements have become more stringent and a method for further reducing the dark current has been required.
Disclosure of Invention The present invention has been made in the technical background as described above, and an object thereof is to provide an apparatus and method for reducing dark current that can not drive the main microcomputer of the vehicle body control module at the start-off.
A dark current reduction device according to an aspect of the present invention includes a main micom that controls functions of the vehicle body control module, except for a security indicator light control, and which does not operate when the vehicle is turned off; And operating in a sleep mode even when the vehicle is turned off, performing the security indicator light control, and detecting a user input as an interrupt, operating the main micom to correspond to the user input by the main micom. And a sub micom for executing a function.
According to another aspect of the present invention, a method of reducing dark current by a sub-microcom of a vehicle body control module may include: operating in a sleep mode when a vehicle is turned off and controlling a security indicator; And detecting a user input as an interrupt, operating the main micom, which is not operated as the vehicle is turned off, and executing a function corresponding to the user input by the main micom. .
According to the present invention, the main microcomputer can not be operated when the vehicle is turned off, so that the dark current can be further reduced, and the cost can be reduced by not using the input IC.
