Embodiment Construction

[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the automobile ignition judging method of the present invention. In this embodiment, the automobile ignition judgment method includes:

[0037] Step S10, reading the current real-time voltage value of the car every first preset time period;

[0038] In this embodiment, there is no limit to the setting of the first preset duration, for example, the current real-time voltage value of the car is read once every 1 second.

[0039] In this embodiment, the current real-time voltage value of the car specifically refers to the voltage value supplied by the car to the on-board equipment, which can be supplied by the motor after the car is started, or by the battery when the car is turned off. In addition, this embodiment does not lim...

Abstract

The invention discloses an automobile ignition judgment method which comprises the following steps: at first preset time intervals, reading current real-time voltage values of an automobile; judging whether a voltage difference between a real-time voltage value read at present and a historical voltage value read at a second current preset time interval is greater than a preset threshold; and if the voltage difference is greater than the threshold, confirming that the automobile has ignition operation at present. The invention further discloses an ignition judgment device and vehicle-mounted equipment. By adopting the automobile ignition judgment method, accurate judgment on an automobile ignition state is conveniently and efficiently achieved.

Description

technical field [0001] The present invention relates to the technical field of on-board equipment, in particular to a method and device for judging ignition of an automobile and on-board equipment. Background technique [0002] Generally, there are two main power supply methods for electronic products used in fuel vehicles: one is powered by the electric energy generated by the vehicle motor after the vehicle is ignited and started; the other is powered by the vehicle after the vehicle is turned off. The battery supplies power to it. However, because the power of the battery is limited, and the car is turned off most of the time in a day, the electronic products used in the car are powered by the battery for a long time, causing a serious loss of battery power, and even affecting the starting of the car. . Contents of the invention [0003] The main purpose of the present invention is to provide a vehicle ignition judging method, device and vehicle-mounted equipment, aim...
