Abstract

The invention belongs to the technical field of automotive electronics, and in particular relates to a vehicle-mounted electronic system, a power management method for vehicle-mounted electronic equipment, and a vehicle. The present invention adopts the vehicle-mounted electronic system including the vehicle-mounted electronic equipment, the ignition detection module and the switch module, and combines the power supply management method of the vehicle-mounted electronic equipment. After the ignition detection module confirms that the car is ignited, it outputs a power-on signal to the switch module to make it conduct The connection between the output terminal of the on-board battery and the power supply terminal of the on-board electronic equipment, and then the on-board electronic equipment enters the power-on state; the on-board electronic equipment outputs a power-on maintenance signal or a power-off signal to keep itself on or off. The system uses pure hardware to realize ignition detection, and can completely turn off the on-board electronic equipment, which solves the problem of continuous power consumption for software detection and meets environmental protection requirements. In addition, the system only needs to be connected to the on-board battery, which has the advantages of simple and convenient wiring .

Description

Technical field [0001] The present invention belongs to the technical field of automobile electronics, and particularly relates to a vehicle-mounted electronic system, a method for power management of vehicle-mounted electronic equipment, and a vehicle. Background technique [0002] With the development of society, people are paying more and more attention to energy issues, and the requirements for power consumption of various electronic devices are getting higher and higher. In vehicle-mounted electronic systems, it is generally required that the on-board electronic equipment can automatically shut down when the car is turned off, and can automatically turn on when the car is ignited. [0003] At present, in the field of automotive electronics technology, it is generally to connect the positive pole of the power supply of automotive electronic equipment to the automotive ACC (Accessories) line. With this scheme, the on-board electronic equipment will be cut off immediately after ...
