Abstract

The invention discloses a power management method for an interconnected automobile electronic device. The interconnected automobile electronic device comprises a voltage detection module and a control module. The power management method comprises the following steps: the voltage detection module detects output voltage of a battery, and corresponding detection voltage is outputted to the control module; and the control module reads the detection voltage, battery voltage is calculated according to the detection voltage, and an ARM module is correspondingly controlled to enter a working state, a dormant state or a shutdown state according to the battery voltage. According to the battery voltage, the ARM module is controlled to enter a working state, a dormant state or a shutdown state, the ARM module works in a stable state, breakdown of the ARM module is avoided, and power depletion of the battery can be avoided.

Description

technical field [0001] The invention relates to an intelligent vehicle control technology, in particular to a power supply management method of an interconnected vehicle electronic device. Background technique [0002] Smart car rearview mirrors generally run on the android and other smart operating systems on the ARM platform to meet functional requirements such as navigation and voice control. Hereinafter referred to as ARM. In the complex environment of the vehicle, ARM may have an unstable working state. [0003] The basic requirement of the on-board equipment is that the electrical equipment must be dormant after the flame is turned off, so as to meet the requirement of saving battery power. And the power supply in the car may be unstable, such as: instantaneous high voltage, or low voltage due to insufficient battery power supply. When the voltage is too low, most of the electrical equipment is required to be in the lowest power consumption state to avoid excessive b...
