Problems solved by technology
[0005] The purpose of the present invention is to provide a method, device and system for vehicle sharp turn recognition, to solve the problem of judging the vehicle turning situation by using accelerator and other related hardware equipment to assist detection, so that the analysis results have large errors, and the sharp turn of the vehicle cannot be distinguished. The specific form of the vehicle is not conducive to the targeted analysis of the driver's driving habits and the problem of judging whether the vehicle has a traffic accident

The invention discloses a method, a device and a system for recognizing sudden turning of a vehicle. The method comprises the following steps: acquiring real-time driving speed and driving angular velocity of the vehicle; if the real-time driving speed and driving angular velocity being within the preset scope of the driving speed and driving angular velocity, calculating a sudden turning safety value according to a preset algorithm; if the sudden turning safety value is greater than a preset safety value, confirming the sudden turning state of the vehicle, thereby recognizing the specific form of the sudden turning of the vehicle and being beneficial to the specific analysis for the driving habit of the driver and the judgment for the traffic accident of the vehicle. According to the method, the related hardware equipment, including accelerator, is not required for collecting the driving acceleration; the detected data is not restricted by the factors, including pavement, tire and vehicle height; the demand on the hardware performance is reduced; the analysis result is accurate.
Description
technical field [0001] The invention relates to the technical field of vehicle monitoring, in particular to a method, device and system for identifying sharp turns of vehicles. Background technique [0002] With the improvement of road traffic conditions and the advancement of automobile technology, the driving speed of vehicles continues to increase, which leads to many safety problems in the process of driving vehicles. Especially when the vehicle is turning, due to the effect of centrifugal force, the high-speed turning of the vehicle may cause the danger of slipping, falling and overturning, and it is easy to cause traffic accidents. [0003] Therefore, the identification of sharp turns is an important part of analyzing whether the driver is driving dangerously. The analysis results can remind the driver to avoid bad driving habits such as fatigue driving, and can determine whether the vehicle has a traffic accident by identifying whether the vehicle is in a sharp turn. ...
