When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, a driving pre-warning apparatus 100 according to the present invention includes a monitor 110 and a pre-warning controller 120.
Specifically, the monitor 110 is used to identify distance and speed information of an object in front of the vehicle. In the present embodiment, the monitor 110 includes a radar monitor device or a laser radar monitor device provided on the front side of the vehicle. The radar monitoring device or the laser radar monitoring device is arranged on the front anti-collision beam or the front grille of the automobile.
The pre-warning controller 120 is electrically connected to the monitor 110, and configured to obtain distance and speed information and send out a pre-warning signal according to the obtained distance and speed information, the pre-warning controller 120 has a laser emitter 121 disposed on one side of the front windshield of the automobile, and the pre-warning controller 120 emits a light warning signal to the front windshield through the laser emitter 121.
