Abstract

The invention aims to provide an overall vehicle power cutoff control system. An overall vehicle power supply can be controlled according to running conditions of a vehicle so as to reduce unnecessary waste of energy and protect batteries. The overall vehicle power cutoff control system comprises a power supply management module and a main power supply switch, connection and disconnection of the main power supply switch are controlled by the power supply management module, and a timing unit and a level detection unit are arranged in the power supply management module; and the power supply management module is respectively connected with a vehicle ignition switch and a charging output end of a power generator and is used for controlling the connection and disconnection of the main power supply switch according to timing of the timing unit, gear information of the vehicle ignition switch and information of the charging output end of the power generator. By adopting the overall vehicle power cutoff control system, a main power supply can be disconnected automatically within certain time when an engine is not started, and the functions of overall vehicle power cutoff and battery protection can be realized. Moreover, no additional operation and influence can be generated for startup and normal running of an overall vehicle.

Description

[0001] technical field [0002] The invention belongs to the technical field of automotive electronics, and in particular relates to a vehicle power-off control system. [0003] Background technique [0004] In a traditional car, when the key is in the "ON" position, although the whole car is not working, other electrical components (such as instruments, work lights, generator excitation, etc.) are still working, which will consume the battery's electric energy and even cause the battery Feed, in the long run, will shorten the service life of the battery. [0005] Contents of the invention [0006] The purpose of the present invention is to propose a vehicle power cut control system, which can control the vehicle power supply according to the working conditions of the vehicle, so as to reduce unnecessary waste of electric energy and protect the storage battery. [0007] The whole vehicle power-off control system of the present invention includes a power management modul...
