Problems solved by technology

[0003] However, if the driver himself is fatigued or mentally in a bad state, it will directly affect the driver's reaction time and further affect the effect of the headway warning function. The car may deviate or even turn suddenly, which will also affect the driving safety of the car and even cause a serious car accident

Abstract

The invention provides a vehicle distance alert threshold adjustment method, system and equipment and a storage medium, which are used for adjusting an inter-vehicle distance alert threshold of a current vehicle and a vehicle in front set by the vehicle. The method includes the following steps: monitoring the fatigue state of a driver of the current vehicle, and obtaining the online grade of the driver of the current vehicle; obtaining the online grade of a driver of the vehicle in front based on Internet of Vehicles; determining the current comprehensive online grade according to a preset mapping relationship among the online grade of the driver of the current vehicle, the online grade of the driver of the vehicle in front and the comprehensive online grade; and calculating the current inter-vehicle distance alert threshold according to a preset correlation between the comprehensive online grade and the inter-vehicle distance alert threshold. By adopting the scheme of the invention, based on an Internet of Vehicles mode, the real-time sharing of online grade information of the drivers is realized, a distance alert threshold setting strategy is also optimized, and thus the drivingsafety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a method, system, device and storage medium for adjusting an automobile time-distance warning threshold. Background technique [0002] It is very necessary to maintain a safe head-to-head distance during vehicle driving. For example, when driving on a highway, it is necessary to maintain a head-to-head time distance of more than 3s to ensure that the self-vehicle has sufficient reaction time when an emergency situation ahead occurs. Therefore, a driving assistance system such as DA (Distance Alert) has appeared in the prior art. The driver sets the time distance warning threshold to be maintained before driving. When the time distance between vehicles is less than the set time distance When the warning threshold is reached, the driving assistance system will issue a warning to remind the driver to pay attention. The difference between it and FCW (Front Collision Warnin...
