Vehicle-mounted electronic system, vehicle-mounted equipment power source management method and vehicle

Abstract

The invention belongs to the technical field of vehicular electronics, and particularly relates to a vehicle-mounted electronic system, a vehicle-mounted equipment power source management method and a vehicle. By adopting the vehicle-mounted electronic system comprising vehicle-mounted electronic equipment, an ignition detection module and a switch module and combining the power source management method of the vehicle-mounted electronic equipment, after confirming that the vehicle is ignited, the ignition detection module outputs a starting signal to the switch module to enable the switch module to enable connection between an output end of a vehicle-mounted storage battery and the vehicle-mounted electronic equipment to be on, and vehicle-mounted electronic equipment is enabled to enter a started state; the vehicle-mounted electronic equipment outputs a start maintaining signal or a stopping signal to enable the same to be started or stopped. By the vehicle-mounted electronic system, ignition detection can be realized by adopting a pure hardware mode, and the vehicle-mounted electronic equipment can be completely switched off, so that the problem of continuous power source consumption when software is adopted for detection is solved, and requirements on environmental protection are met; the system only needs to be connected with the vehicle-mounted storage battery, thereby having the advantages of simplicity and convenience in wiring.

Description

technical field [0001] 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. Background technique [0002] With the development of society, people pay more and more attention to energy issues, and the requirements for power consumption of various electronic devices are getting higher and higher. In the on-board electronic system, it is generally required that the on-board electronic equipment can be automatically shut down when the car is turned off, and can be automatically turned on when the car is ignited. [0003] At present, in the field of automotive electronics technology, the positive pole of the power supply of the vehicle electronic equipment is generally connected to the ACC (Accessories, accessories) line of the vehicle. With this solution, the vehicle-mounted electronic equipment will be shut off ...
