Abstract

The invention relates to an apparatus and a method for monitoring the awakening based on battery connection of a vehicle. The awakening monitoring apparatus is characterized in that when awakening based on resetting generated by a microcomputer of the vehicle occurs, it can be learnt whether the awakening is generated by the resetting based on an initial power source of the vehicle battery. According to the invention, the awakening apparatus has the effects of reducing standby electric current and saving power, i.e., when an accessory power source is closed, standby electric current consumption can be prevented such that the standby electric current can be usefully used to cut a multimedia H / U microcomputer circuit of the power source.

Description

technical field [0001] The present invention relates to a wake-up monitoring device and method thereof, in particular to a device and method for monitoring wake-up based on vehicle battery connection when wake-up based on reset. Background technique [0002] like figure 1 As shown, conventionally, it is a method of waking up based on an interruption by connecting a normal power supply. Therefore, supplying normal power to the microcomputer consumes standby current even when the power supply of the vehicle accessories is turned off. [0003] Take corresponding countermeasures, such as figure 2 As shown, a circuit that cuts off the power supply to the microcomputer and the reset circuit when the accessory power is turned off is required. [0004] However, just use figure 2 In the case of the circuit shown, whenever the power of the accessory is turned on, the microcomputer is reset to realize wake-up. Therefore, the wake-up mode needs to be defined separately. That is, s...
