In fact, this regards acceleration as the only basis for judging sharp turns, but ignores the role of speed, an important driving parameter. For example, for the same magnitude of lateral acceleration, the turning degree of a high-speed car is lower than that of a low-speed car

Abstract

The invention discloses a judgment method for automobile driving stability on the basis of speed and gyroscope data. On the basis of the speed and the gyroscope data of an automobile, a mathematical model is established, and the accurate automobile driving accelerated speed of an accelerated speed sensor method used in the prior is solved. On the basis, heading direction accelerated speed and yawangle speed are aimed to define three variables used for carrying out statistics and judging rapid acceleration, rapid slowdown and sharp turn events. In an automobile driving process, the values of the variables of rapid acceleration, rapid slowdown and sharp turn events are independently subjected to statics. According to the values of rapid acceleration, rapid slowdown and sharp turn events, automobile driving stability is accurately and efficiently judged, and therefore, an improvement advice is put forward for the bad driving behavior of a user.

Description

technical field [0001] The invention belongs to the field of vehicle monitoring, in particular to a method for judging vehicle driving stability based on speed and gyroscope data. Background technique [0002] The Internet of Vehicles technology is one of the hot areas of current automotive technology research. With the rise of the Internet of Vehicles technology, the analysis of driving habits such as mileage, real-time fuel consumption, fatigue and driving stability has increasingly attracted the attention and attention of car users. And a large number of people in related fields have proposed a variety of research and solutions. However, as far as the driving stability analysis is concerned, most of the existing technologies currently have some defects or deficiencies in various degrees. [0003] For example, the application number is CN201610251846.1, an automatic driving behavior optimization method, on the basis of the preset threshold, through the direct judgment of ...
