Abstract

The embodiment of the invention discloses a driving state determination method and device, a vehicle and a storage medium. The method comprises the following steps that a model, a current vehicle speed and a historical vehicle speed of the vehicle are obtained, a current vehicle acceleration is determined according to the current vehicle speed and the historical vehicle speed, an acceleration threshold value corresponding to the current vehicle speed is determined by combining a vehicle speed threshold relation table according to the current vehicle speed, the vehicle speed threshold relationtable is determined according to the model and the vehicle speed of the vehicle, and the vehicle is currently determined to be at a high speed state when the vehicle acceleration is greater than or equal to the acceleration threshold value. Compared with the prior art, the vehicle speed threshold relation table of the embodiment of the invention is determined according to the model and the vehiclespeed of the vehicle, when the model or the vehicle speed of the vehicle changes, the vehicle speed threshold relation table changes correspondingly, the obtained acceleration threshold value changescorrespondingly as well, so that the acceleration threshold value can meet the actual change condition of the vehicle, and the degree of accuracy of the driving state determination is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of safe driving, and in particular to a method, a device, a vehicle, and a storage medium for determining a driving state. Background technique [0002] Usage Based Insurance (UBI Insurance for short) is a type of auto insurance that is priced according to the user's driving habits. When evaluating the type of insurance paid for a vehicle, the insurance company usually analyzes the driving habits of the user corresponding to the vehicle, and determines the appropriate type of insurance based on the analysis results. The user's driving habits can be determined according to the driving state to a certain extent. Therefore, the accuracy of the driving state judgment directly affects the judgment of the user's driving habits, which in turn affects the determination of the type of car insurance. Among them, rapid acceleration and deceleration are important performances of the driving sta...
