Problems solved by technology

[0002] With the rapid development of the automobile industry, people rely more on cars for travel. However, due to the visual blind spots on the left and right sides of the car, it is difficult for the driver to accurately identify all obstacles in the blind spots when the car is driving, which may easily lead to safety problems. the occurrence of the accident
[0003] At present, among the early warning sensors of automobile blind spots, the detection field angle range of the millimeter-wave radar is usually ±60°~±75°.

Embodiment Construction

[0043] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is expressed as being "fixed" / "installed" on another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "vertical", "horizontal" etc. used in this specification is based on the orientation or positional relationship shown in the drawings, It is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the device or elem...

Abstract

The embodiment of the invention discloses a blind area early warning radar and a blind area early warning system, the blind area early warning radar comprises a first detection assembly and a second detection assembly, the first detection assembly is used for emitting a first electromagnetic wave, the first electromagnetic wave has a first detection viewing angle, and the second detection assemblyis used for emitting a second electromagnetic wave, the second electromagnetic wave has a second detection viewing angle. Two adjacent sides of the first electromagnetic wave and the second electromagnetic wave intersect or coincide, and a detection field angle formed by superposing the first detection viewing angle and the second detection viewing angle is larger than or equal to 180 degrees. Bymeans of the arrangement, the blind area early warning radar can conduct detection with the field angle of 180 degrees, the detection blind area is eliminated, and the safety of automobile driving isimproved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile robots, in particular to a blind spot early warning radar and a blind spot early warning system. Background technique [0002] With the rapid development of the automobile industry, people rely more on cars for travel. However, due to the visual blind spots on the left and right sides of the car, it is difficult for the driver to accurately identify all obstacles in the blind spots when the car is driving, which may easily lead to safety problems. Accidents happen. [0003] At present, among the early warning sensors for blind spots in automobiles, the detection field of view of the millimeter-wave radar usually ranges from ±60° to ±75°. The detection field of view is small, and there is a large detection blind spot, which poses a safety hazard. Contents of the invention [0004] The technical problem mainly solved by the embodiments of the present invention is to provi...
