Embodiment 1

[0040] This embodiment calculates the current vehicle motion state (forward, backward, parking) according to the GPS trajectory and speed in a short period of time in the past, and according to the abnormal characteristics of the GPS positioning signal, the process is designed in a targeted manner, and the odometer data is used to improve the accuracy of motion state judgment Spend. In the actual production environment, the inventive algorithm has good expected performance and can effectively reduce the misjudgment rate.

[0041] like figure 1 As shown, the present embodiment provides a vehicle driving state detection method, comprising the following steps:

[0042] S1: Obtain the running speed of the vehicle within a preset time through GPS, and judge whether the running speed of the vehicle is lower than the parking speed threshold, if yes, then output the state "stop", if not, then perform step S2; the parking speed threshold is 0.07m / s. In this step, it is to judge wh...

Embodiment 2

[0054] Embodiment 2 discloses an electronic device, which includes a processor, a memory, and a program, wherein one or more processors and memories can be used, and the program is stored in the memory and configured to be executed by the processor, When the processor executes the program, the vehicle driving state detection method of Embodiment 1 is realized. The electronic device may be a series of electronic devices such as a mobile phone, a computer, and a tablet computer.

Embodiment 3

[0056] Embodiment 3 discloses a readable computer storage medium, which is used to store a program, and when the program is executed by a processor, the vehicle driving state detection method of Embodiment 1 is implemented.

[0057] Certainly, a storage medium containing computer-executable instructions provided by an embodiment of the present invention, the computer-executable instructions are not limited to the method operations described above, and may also execute the content-based update notification method provided by any embodiment of the present invention Related operations in .

[0058] Through the above description about the implementation mode, those skilled in the art can clearly understand that the present invention can be realized by means of software and necessary general-purpose hardware, and of course it can also be realized by hardware, but in many cases the former is a better implementation mode . Based on this understanding, the essence of the technical so...

Abstract

The invention discloses a detection method for the driving state of a vehicle. The detection method comprises the following steps: determining whether the moving speed of the vehicle is lower than a threshold of a parking speed; determining whether the moving speed of the vehicle is lower than a threshold for driving monitoring, and if so, executing a mileage acquisition step, or if not, executinga trajectory acquisition step; determining whether the vehicle is in a moving speed according to the data of a mileometer, and if so, executing the trajectory acquisition step; acquiring a GPS movingtrajectory within preset time, determining whether the GPS moving trajectory is continuously forwarding, and if so, executing a second determination step; and determining whether the direction of theGPS moving trajectory is consistent with the orientation of the head of the vehicle. The invention also provides an electronic instrument and a computer-readable storage medium. The detection methodfor the driving state of the vehicle in the invention determines the current driving state of the vehicle by combining GPS data and the data of the mileometer, so the accuracy of the driving state ofthe vehicle is improved, and the misjudgement rate of a driving test evaluation system is reduced.

Description

technical field [0001] The invention relates to the technical field of driving test, in particular to a method and device for detecting the driving state of a vehicle. Background technique [0002] At present, most of the automatic evaluation systems for mainstream subjects two and three driving tests use high-precision satellite positioning data and on-board motion sensor data as the basis for evaluation. Among them, the positioning data is used to determine the position, speed, and direction of travel of the vehicle, and the motion sensor is used to determine information such as student actions, stepping on the brakes, stepping on the clutch, and lighting operations; the reliability of the collected data directly affects the accuracy of the automatic evaluation system for driving tests sex. [0003] In actual use, high-precision satellite positioning technology is easily affected by the external environment (signal interference, occlusion, reflection) and becomes unreliab...
