Problems solved by technology

[0002] In the field of Internet of Vehicles, how to deal with the collision risk of the vehicle is a key issue for safe assisted driving. At present, the vehicle often randomly selects a fixed threshold as the collision warning threshold, without considering different types of road sections, different types of vehicles, and road condition information. As a result, the rate of missed alarms and false alarms is very high, which reduces the user experience.

Abstract

The embodiment of the invention provides a vehicle collision early warning threshold determination method and device. The method comprises the following steps: virtualizing different types of virtualvehicles on a target road section according to vehicle types; according to a lane speed of the target road section, obtaining a plurality of virtual safe collision distances between a target vehicle located on the target road section and the different types of virtual vehicles; determining virtual collision early warning thresholds between the target vehicle and the different types of virtual vehicles based on the plurality of virtual safe collision distances; and determining a corresponding collision early warning threshold of the target vehicle on the target road section according to the virtual collision early warning threshold and other vehicles located on the target road section. According to the technical scheme provided by the embodiment of the invention, the collision early warningthreshold of the corresponding road section can be determined more specifically and accurately, the collision early warning of the vehicle can be realized more effectively, and a missed warning rateand a false warning rate are reduced.

Description

technical field [0001] The present application relates to the technical field of Internet of Vehicles, in particular, to a method and device for determining a vehicle collision warning threshold. Background technique [0002] In the field of Internet of Vehicles, how to deal with the collision risk of the vehicle is a key issue for safe assisted driving. At present, the vehicle often randomly selects a fixed threshold as the collision warning threshold, without considering different types of road sections, different types of vehicles, and road condition information. As a result, the rate of missed alarms and false alarms is high, which reduces user experience. Contents of the invention [0003] Embodiments of the present application provide a method and device for determining a vehicle collision warning threshold, and at least to a certain extent, can determine the collision warning threshold of the corresponding road section more specifically and accurately, and then can ...
