AI Technical Summary

Benefits of technology

The technology described in this patented describes an algorithm that helps predict potential hazards on road networks based upon their current conditions or how they move around over time. This allows for more accurate prediction than just looking at past data alone.

Problems solved by technology

This patented technical problem addressed by this patents relating to autonomously driven vehicles (ADVs) involves understanding how objects move around within their surrounding environments without being affected or influenced negatively through external forces such as gravity waves caused by other moving things like cars).

Embodiment Construction

[0038] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, rather than to limit the invention. It should also be noted that, for the convenience of description, only the parts related to the related invention are shown in the drawings.

[0039] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0040] The risk of driving is affected by a variety of factors, and the risk of driving is not a black and white polar issue. Whether a factor poses a danger to driving is itself a very vague concept. According to the fuzzy characteristics of driving risk, this application r...

Abstract

The invention provides a traffic environment modeling method which comprises the following steps: calculating the collision probability of a vehicle and an object according to the position of the vehicle, the position of the object and a distribution factor; calculating the risk level of the object according to the type, size and speed of the object; calculating a driving environment risk field according to the collision probability of the vehicle and the object and the risk level of the object; and according to the driving environment risk field, modeling is carried out to generate a risk distribution map in the traffic environment. Therefore, the complex traffic environment is normalized, different traffic environments are quantized in a unified manner, and the motion states of the traffic elements are added into environment modeling, so that potential risks are reflected.
