Embodiment Construction

[0066] In order to facilitate the understanding of the present disclosure, the implementation environment of the data sending method is introduced here, see Figure 1A , the implementation scenario includes a first device, a second device, a roadside sensor, a base station, and a risk analysis device.

[0067] The first device is any terminal device that supports vehicle-to-everything V2X, for example, an On-Board Unit (OBU), a smart phone, an on-board control unit T-Box, or a driving recorder. Taking the OBU as an example, the OBU can be in the form of a car or a combination of a T-Box and a smartphone. OBU can obtain status data such as lane-level position data and vehicle speed, and periodically send the data to TCU (Traffic Control Unit, TCU) through the cellular network, and OBU can receive risk data, such as alarms, events, signal lights, signs, etc. , and based on these risk data, the driver is prompted through voice, video, etc. Other possible implementation forms of ...

Abstract

The invention relates to a driving risk analysis and risk data sending method and device and belongs to the Internet of vehicles technology field. The method comprises steps that the position of firstequipment is acquired, and the first equipment is equipment of which risk analysis is to be carried out; first risk areas are determined according to vehicle driving lines corresponding to the position, and the first risk areas are areas having influence on driving behaviors of location vehicles of the first equipment; the first risk areas are screened to acquire risk data; the risk data is sentto the first equipment; the risk data comprises the vehicle, pedestrian and obstacle state data having bump risks with the location vehicles of the first equipment and traffic environment data havinginfluence on the driving behaviors of the location vehicles of the first equipment. The method is advantaged in that data sending time delay is reduced, bandwidth requirements of mutually-notified vehicle state data among the equipment are reduced, air interface resource scheduling frequency requirements are further reduced, and communication performance is improved.

Description

technical field [0001] The present disclosure relates to the technical field of Internet of Vehicles, in particular to a driving risk analysis and risk data sending method and device. Background technique [0002] Vehicle to Everything (V2X) technology is an emerging development trend of the Internet of Vehicles. V2X is a combination of Vehicle to Vehicle (V2V), Vehicle to Pedestrian (V2P) and Vehicle to Internet (Vehicle to Internet) technologies. , V2I) collectively. In order to ensure the safe driving of vehicles, different vehicles on the road need to be able to exchange some data with each other. Through the processing of these data, the road and vehicle conditions, such as vehicle accidents ahead, etc. can be obtained; even the occurrence of accidents can be predicted in advance, and then Warn the driver to change his driving strategy. [0003] With the development of V2X technology, long-term evolution-V2X (Long Term Evolution-V2X, LTE-V2X) technology is gradually i...
