Embodiment 1

[0022] figure 1 The implementation flow of the monitoring method for the start-stop state of the automobile provided by Embodiment 1 of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0023] In step S101, the voltage data of the car battery within a preset time period is obtained, and the variation rule of the voltage within the preset time period is obtained according to the voltage data.

[0024] In the embodiment of the present invention, the time period for collecting the voltage data of the car battery is preset, so as to obtain the change rule of the voltage within the preset time period. Preferably, the preset collection time period is 3 seconds, and the voltage value is collected every 100 milliseconds within 3 seconds to obtain 30 voltage values. When obtaining the change rule of the voltage, specifically, set the first collected voltage ...

Embodiment 2

[0036] figure 2The implementation process of the monitoring method for the start-stop state of the automobile provided by the second embodiment of the present invention is shown. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

[0037] In step S201, the voltage data of the car battery within a preset time period is obtained, and the variation rule of the voltage within the preset time period is obtained according to the voltage data.

[0038] In step S202, it is judged whether the engine speed of the vehicle is in the public state.

[0039] In step S203, when the engine speed of the car is not in the public state, compare the change rule of the voltage with the preset change rule of the voltage during the start-stop process of the car, and compare the result of the comparison with the state of the car before the preset time period , to get the current state of the car.

Abstract

The invention is applicable to the technical field of automobiles, and provides an automobile start-stop state monitoring method and device. The method comprises the steps of obtaining voltage data of an automobile battery within a preset time period, obtaining a change rule of the voltage within the preset time period according to the voltage data, judging whether or not an automobile engine revolution is in an open state, when the automobile engine revolution is in the open state, obtaining the automobile engine revolution within the preset time period, comparing the change rule of the voltage and the engine revolution with a preset change rule of the voltage and a preset engine revolution in an automobile start-stop process, and obtaining a current state of the automobile according to a comparing result and a state of the automobile before the preset time period. According to the automobile start-stop state monitoring method and device, the process of obtaining the automobile start-stop state is simplified, and the timeliness and accuracy of obtaining the automobile start-stop state are improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a method and device for monitoring the start-stop status of automobiles. Background technique [0002] With the development of Internet of Vehicles technology, vehicle or automobile information perception technology, as an important part of Internet of Vehicles, has also attracted much attention. The timeliness and reliability of automobile information perception technology will directly affect the user experience of Internet of Vehicles products. [0003] At present, there are three main methods for sensing the start and stop status of automobiles. In the first method, the start and stop information is directly read through Controller Area Network Bus (CANBus) data. However, automobiles of different brands Different CANBus data protocols may be used, so this method can only be used for the start-stop perception of specific brands of cars, and cannot satisfy the p...
