Embodiment Construction

[0015] Such as figure 1 As shown, the adaptive virtual point flameout detection method based on the voltage change of the automobile battery includes two steps of initial detection and dynamic adjustment;

[0016] Among them, the initial detection steps are as follows:

[0017] First, install the device on the car. According to different models, preset a set of threshold parameters for initial detection point flameout. The threshold parameters include ignition voltage value (Ignition On Voltage) and ignition voltage compensation (Ignition Voltage Offset), and the terminal equipment The ignition voltage value, the flameout voltage value and the ignition voltage deviation at one end time determine the ignition voltage boundary line, wherein the ignition voltage boundary line is located between the ignition voltage value and the flameout voltage value.

[0018] Secondly, detect the ignition voltage value, and compare the ignition voltage value with the ignition voltage boundary ...

Abstract

The invention discloses a self-adaptive virtual ignition-on-off detection method based on vehicle storage battery voltage change. The method comprises the following steps of 1, presetting a group of threshold value parameters for initially detecting ignition on and off, wherein the threshold value parameters comprise ignition on voltage and ignition voltage offset, and an ignition-on-off voltage boundary is decided according to the ignition on voltage, ignition off voltage and deviation values the of ignition on voltage; 2, detecting the current ignition on voltage, comparing the ignition on voltage and the ignition-on-off voltage boundary, judging that a vehicle is in an ignition-on state at this moment and recording the current voltage and the ignition on offset if the ignition on voltage is larger than the ignition-on-off voltage boundary; judging that the vehicle is in an ignition-off state at this moment and recording the current voltage and ignition off offset if the ignition onvoltage is smaller than the ignition-on-off voltage boundary.

Description

technical field [0001] The invention relates to an adaptive virtual point flameout detection method based on the voltage change of an automobile storage battery. Background technique [0002] With the rapid development of the Internet of Things and the Internet of Vehicles technology, more and more vehicle-mounted electronic terminals need to detect the ignition and shutdown status of the vehicle. At present, the method of detecting ignition of electronic products on the market generally uses reading the state of the car engine as the basis for judging ignition. This method requires the installer to have a relatively deep understanding of the vehicle in the actual installation process, which has certain installation difficulties. At the same time, hardware costs and installation costs are also increased. Contents of the invention [0003] The invention provides an adaptive virtual point-off detection method based on the voltage change of the automobile battery, overcomes...
