US 2022/0036735 A1 · REAL-TIME DRIVING RISK ASSESSMENT METHOD EMPLOYING EQUIVALENT FORCE AND DEVICE THEREOF

Abstract

A real-time assessment method of driving risk based on equivalent force includes: S1, collecting traffic environment information and various types of traffic environment use object information in a road environment in an area to be assessed; S2, inputting, into an electronic control unit of a vehicle, the traffic environment use object information and the environment information acquired in S1, wherein a road risk assessment model based on the equivalent force distribution is preset in the electronic control unit; S3, using the road risk assessment model, so as to acquire road traffic risk E of the vehicle i and equivalent force distribution Fij between the vehicle i and the object j in different traffic environments, wherein the object j represents any traffic element other than vehicle i in various traffic environment use object information. A real-time assessment device of driving risk based on equivalent force is further provided.

Dependent claims

A real-time assessment method of driving risk based on equivalent force, comprising:

S1, collecting traffic environment information and various types of traffic environment use object information in a road environment in an area to be assessed;
S2, inputting, into an electronic control unit of a vehicle, the various types of traffic environment use object information and the traffic environment information acquired in S1, wherein a road risk assessment model based on an equivalent force distribution is preset in the electronic control unit;
S3, using the road risk assessment model to acquire a road traffic risk E of a vehicle i and an equivalent force distribution Fij between the vehicle i and an object j in different traffic environments, wherein the object j represents any traffic element other than the vehicle i in the various types of traffic environment use object information, the road traffic risk E is expressed as a sum of kinetic energy Ei of the vehicle i, kinetic energy Ej of the object j, and relative kinetic energy Eij between the vehicle i and the object j.

A real-time assessment device of driving risk based on equivalent force, comprising:

an information collecting unit, wherein the information collecting unit is configured to collect traffic environment information and various types of traffic environment use object information in a road environment in an area to be assessed;
and
an electronic control unit, wherein electronic control unit is preset with a road risk assessment model based on an equivalent force distribution, the electronic control unit is configured to receive the traffic environment information and the various types of traffic environment use object information collected by the information collection unit;
wherein the road risk assessment model is used to acquire a road traffic risk E of a vehicle i and an equivalent force distribution Fij between the vehicle i and an object j in different traffic environments, and the object j represents any traffic element other than the vehicle i in the various types of traffic environment use object information, the road traffic risk E is expressed as a sum of kinetic energy Ei of the vehicle i, kinetic energy Ej of the object j, and relative kinetic energy Eij between the vehicle i and the object j.
