Automatic electricity saving method and device for vehicle GPS equipment, and vehicle GPS equipment

Abstract

The invention discloses an automatic electricity saving method and device for vehicle GPS equipment, and the vehicle GPS equipment. The method comprises steps that step S100, whether a vibration sensor has invalid vibration is monitored in real time, and invalid vibration refers to vibration of which a monitored vibration value is smaller than a preset vibration threshold; step S200, when invalid vibration is monitored by the vibration sensor, whether monitored vibration values within the first timing time T1 are all invalid vibration values is determined; S300, within the first timing time T1, if all the monitored vibration values are the invalid vibration values, an ACC state value is marked as closing; and step S400, after the ACC state value is marked as closing, a GPS module is closed. The method is advantaged in that the ACC state value is determined on the basis of the vehicle vibration value, the vehicle GPS equipment is closed or started on the basis of the ACC state value, a problem of dependence of the vehicle GPS equipment onto the vehicle ACC signal can be solved, the vehicle GPS equipment can be further normally closed even when the ACC signal is invalid, and thereby the automatic electricity saving effect is realized.

Description

Technical field [0001] The present invention relates to the technical field of power saving for vehicle-mounted equipment, in particular to a method, device and equipment for automatically saving power for vehicle-mounted GPS equipment. Background technique [0002] Existing vehicle GPS (Global Positioning System, global positioning system) equipment is usually connected in parallel with the vehicle circuit, while the battery power of general passenger vehicles is about 32AH to 80AH. When the vehicle is parked for a long time, the vehicle’s own on-board circuit And the device will continue to consume battery power, and the use of the loaded GPS device will accelerate the consumption of the vehicle’s battery power, causing the vehicle to not start normally when in use. [0003] In order to solve the problem of vehicle-mounted GPS equipment speeding up the power consumption of the vehicle, a commonly used method in the prior art is to realize the power consumption processing of the G...
