Problems solved by technology

This method is limited by the environment and the three-dimensional and moving characteristics of the vehicle, making the collected information inaccurate
[0004] Another example is the invention patent CN200510118935, which uses a camera to capture the environment behind the vehicle and then visualizes it. The device is used in this way, but the device is not fully utilized, and only the situation behind the vehicle can be observed

Embodiment Construction

[0027] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0028] The invention relates to a visual collision warning method based on the Internet of Vehicles, which enables the driving status of neighbor vehicles to be displayed in real time on the vehicle screen and provides collision warning prompts. The architecture of the method provided by the invention is as figure 1 shown. This method is based on the inter-vehicle cooperation of VANET technology, so that all vehicles can display the location of neighboring vehicles in real time through the vehicle-mounted display, as well as prompts on whether there is a risk of collision with the own vehicle and real-time road condition information. In this embodiment, the present invention includes, but is not limited to, coloring of neighboring vehicles to represent whether there is a risk of collision with the vehicle, such as green for the c...

Abstract

The invention provides a visualized early warning method against collision based on the Internet of Vehicles. According to the method, vehicles exchange state messages by utilizing the vehicular Ad-hoc network technology to sense the driving states of vehicles in the surrounding, limit of the visibility is overcome, position information of vehicles that cannot be seen can be received, and after receiving the information, a vehicle can use a collision early-warning algorithm to determine whether the vehicle may collide with a neighbor vehicle. According to the invention, satellite positioning coordinates are converted into vehicle-mounted screen coordinates, and the driving positions and states of the vehicle and the neighbor vehicle are displayed in a vehicle-mounted screen in real time.

Description

technical field [0001] The invention relates to a method capable of displaying in real time the position of a neighboring vehicle and a warning of whether there is a risk of collision with the own vehicle through a vehicle-mounted display, and belongs to the field of vehicle active safety. Background technique [0002] In the previous inventions of collision visualization warning methods, the research status is roughly divided into two directions, one is to use the auxiliary equipment of the vehicle, and the other is to use the cooperation between vehicles. In the past inventions and subject research, for example, many literature studies collected the environmental information around the vehicle based on radar and various sensors as information receiving methods, and handed it over to the vehicle processor for visual processing. Such existing auxiliary devices are particularly susceptible to being limited by environmental factors, as well as being limited to the range of sig...
