Embodiment 1

[0079] Such as figure 1 As shown in , a vehicle motion posture mutual sensing device, the schematic diagram of its main components is shown in figure 2 shown, including:

[0080] The shell 1, the upper part of the shell 1 is open, and the upper cover 4 is arranged at the opening; the upper interface plate 7 is arranged near the opening inside the shell 1, and the lower interface plate 5 is arranged near the bottom, and the upper interface plate 7 and the lower interface plate 5 A main interface board 6 is arranged between them. The shell 1 is made of non-metallic wave-transparent material, so as to ensure that electromagnetic waves can pass in and out without attenuation. The function of the shell is to protect the internal equipment, and at the same time ensure that the direction of the working system of the device is parallel to the front direction of the vehicle. Anti-reversal layout openings are used to ensure that the direction of each interface board and the signal d...

Embodiment 2

[0109] The present invention also provides another method for mutual perception of vehicle motion states, such as Figure 5 As shown, it is still based on the device in the first embodiment, but different from the method in the first embodiment, the directional transponder and the second sensor are used to form the positioning system by using the second communication component and the signal separation and shielding inner shell. When the first sensor loses signal, the normal operation of the device can still be guaranteed, thereby greatly improving the reliability of the device. The specific methods can be as follows:

[0110] A1 obtains the surrounding vehicle broadcast signals received by each sensing sector of the second communication component, and transmits the vehicle type and the sensing sector number to the second communication component of the surrounding vehicle through each sensing sector; the second communication component It includes a plurality of sensing sectors...

Embodiment 3

[0122] The present invention also provides a third method for mutual perception of vehicle motion states. The difference from Embodiment 1 and Embodiment 2 is that in this embodiment, when the first sensor can work, the method of Embodiment 1 is used. When the first sensor fails and cannot work normally, the method of the second embodiment is put into use as a backup method, so as to ensure that the vehicle can still run normally and smoothly even when the vehicle positioning is abnormal.

[0123] The method for mutual awareness of vehicle movement posture provided by this embodiment, forms a single-hop peer-to-peer wireless interconnection communication network with the first communication component of the same device in other vehicles via the first communication component, and announces the position coordinates acquired by the first sensor, The speed vector and the attitude vector acquired by the second sensor are integrated and calculated by the computing component, and the ...

Abstract

The invention relates to a vehicle motion posture mutual sensing method and device, and the device comprises an outer housing, a signal separation shielding inner housing, a calculation assembly, a first communication assembly, a second communication assembly, a first sensor, a second sensor, and an operation auxiliary assembly. By combination and application of the parts mentioned above, a single-hop peer-to-peer wireless interconnection communication network is formed by a first communication assembly and a first communication assembly of the same device in other vehicles, position coordinates, speed vectors and attitude vectors are mutually announced, information integration calculation is carried out by utilizing a calculation assembly, and vehicle-mounted central control is mapped through interconnection of the first communication assembly. The distribution of surrounding vehicles is visually displayed in the form of a radar distribution diagram, vehicle motion trail conflict pre-judgment and danger early warning functions are provided, the second communication assembly and the signal separation shielding inner shell form a directional responder, the directional responder andthe second sensor form a redundant system, and it is guaranteed that the system continues to work when the first sensor loses signals. The method and the device can be widely applied to the field of vehicle auxiliary driving.

Description

technical field [0001] The invention relates to the technical field of vehicle electronic products, in particular to a method and device for mutual perception of vehicle motion states. Background technique [0002] In vehicle automatic driving and assisted driving related technologies, the information perception of the motion posture and driving intention of adjacent vehicles is one of the prerequisites for safe driving. In the defensive driving technology, it is first necessary to fully understand and judge the relative position, motion posture, and driving intention of adjacent vehicles, and comprehensively process and process the above information, in order to realize the prediction of risk factors, and realize the accurate formulation and precise implementation of safe driving strategies. The existing automatic driving and assisted driving technology systems take the vehicle itself as the first perspective, and carry out information perception to design and realize the c...
