Description
Technical Field
The utility model relates to the technical field of automobile driving, in particular to a double-probe ultra-wide-angle radar device.
Background
In the current society, with the increasing amount of automobiles kept, people choose more automobiles as primary vehicles, which greatly facilitates people's lives.
A series of radar products, such as millimeter wave radar sensors, are usually installed on an automobile, and such sensors are usually installed at the tail of the automobile, so as to detect the condition of a road around the automobile, and further identify whether other vehicles or obstacles are approaching around, and finally ensure driving safety.
In the prior art, two millimeter wave radar sensors are typically employed as part of a lane change assist system for a motor vehicle. Two millimeter wave radar sensors are installed on both sides of the rear of the vehicle, respectively, so as to detect left and right lanes, respectively.
However, the above-mentioned prior art has various drawbacks and inconveniences in mounting the corresponding radar sensors on the left and right sides of the rear of the automobile, respectively. For example, two radar sensors typically need to be mounted precisely to the bumper of the rear of an automobile. This mounting process is very tedious and time consuming, because the mounting process requires a specialized tool to be aimed at the bumper to find the mounting location, and a marker pen to draw a location line on the bumper, thus the mounting is very time consuming and laborious.
In addition, for a car or truck without an automobile tail bumper, two radar sensors are hardly installed because the car tail is of a smooth arc shape and is not a flat surface. Alternatively, in the case where the tail bumper is not rectangular in cross section, the radar sensor cannot be mounted.
In addition, in the prior art, the two radar sensors can only be installed at the tail of the automobile, so that the road area behind the automobile can only be detected, but the road areas on the left side and the right side of the automobile cannot be detected, so that the detection blind area is formed to a certain extent, and traffic accidents are easy to occur.
