It should be understood that the collision avoidance controller 12 may be connected to the distance detecting device 11 and the rear windshield 13 by wires, or may be connected wirelessly. For example, a first receiving unit and a first transmitting unit of wireless signals may be provided in the anti-collision controller 12; a second transmitting unit of wireless signals may be disposed in the distance detecting device 11 to transmit the detected distance information to the anti-collision controller 12; a second receiving unit of wireless signals may be disposed in the rear windshield 13 to receive the instruction for displaying the reminding information sent by the anti-collision controller 12.
Note that, in the present embodiment, the distance detecting device 11 is configured to detect a distance between a first vehicle and a second vehicle located behind the first vehicle. A collision avoidance controller 12 for detecting a risk of collision between the first vehicle and the second vehicle. And a rear windshield 13 for displaying a warning message when the collision avoidance controller 12 recognizes that there is a collision risk.
Alternatively, the distance detecting device 11 is installed in the middle of the rear bumper of the first vehicle so that it detects the distance between the first vehicle and the second vehicle.
Further, a plurality of distance detecting devices 11 may be provided on the rear bumper of the first vehicle to improve the accuracy of detecting the distance. Alternatively, a plurality of distance detecting devices 11 may be symmetrically mounted on the first rear bumper. It should be understood that, in the present embodiment, the distance detection means 11 may be a millimeter wave radar or an image pickup means; the image acquisition device may be a video camera or a still camera.
The millimeter wave radar ranging principle is as follows: it sends out radio waves (millimeter waves), receives echoes, and measures position data and relative distance of an object based on the time difference between the transmission and reception. From the propagation speed of the electromagnetic wave, the distance between the host vehicle and the target (rear vehicle) can be determined as: and s is ct/2, wherein s is the target distance, t is the time from the emission of the electromagnetic wave from the radar to the reception of the target echo, and c is the speed of light.
The principle of the distance measurement of the image acquisition device can be as follows: and acquiring the image of the rear vehicle by using the image acquisition device, and comparing the size of the image of the rear vehicle with the size of a pre-stored image in the current vehicle to determine the distance between the two vehicles. For example: when the distance is a and the size of the image of the following vehicle at the distance pre-stored in the vehicle is B, if the size of the image of the following vehicle collected in real time is B, the distance between the two vehicles can be determined to be a.
Optionally, a display screen is provided on the rear windshield 13 for displaying a warning message, that is, a warning message is displayed on the display screen. Wherein, the reminding message can flash on the display screen according to the preset frequency. It should be understood that the reminder message may be a "warning" or "warning" text message.
Optionally, the rear windshield 13 has a projection function, through which the warning message can be projected onto the ground behind the first vehicle, via the rear windshield 13. Wherein, the rear windshield 13 can control the reminding message to flash.
Optionally, the anti-collision system reminding system further includes: the acoustic warning device 14 and the acoustic warning device 24 are connected to the collision avoidance controller 12 and are configured to emit an acoustic warning message when the collision avoidance controller 12 recognizes that there is a collision risk. The sound reminding device 14 may be a speaker or a buzzer.
Optionally, the anti-collision system reminding system further includes: a flash lamp. Wherein the flashing light is connected with the anti-collision controller 12 and is used for sending out a light reminding message when the anti-collision controller 12 recognizes that the collision risk exists. Wherein the flashlight is arranged at the tail part of the first vehicle. For example, the flasher may be provided on a rear bumper or on a back door of the vehicle.
To facilitate understanding of the anti-collision reminding system in the present embodiment, the principle of the anti-collision reminding system will be briefly described below.
As shown in fig. 2, during the driving of the current vehicle (the first vehicle in the above), the distance detecting device 11 on the rear bumper thereof will detect the distance between the current vehicle and the vehicle (the second vehicle in the above) behind the current vehicle in real time; and transmits the detected distance information to the collision avoidance controller 12. The collision avoidance controller 12 will analyze the distance information it receives. If the distance is less than the first preset safe distance threshold, the collision avoidance controller 12 identifies that a collision risk (i.e., rear-end collision) exists between the two vehicles; at this time, it will send a warning message to the rear gear glass 13 that displays a collision warning; at the same time, the display screen on the rear windshield 13 will display the corresponding reminder information. If the distance is smaller than the second preset safety distance threshold, the anti-collision controller 12 may control the sound reminding device 14 located behind the current vehicle to send out a sound alarm, so as to better remind the driver of the vehicle behind, thereby ensuring driving safety and preventing rear-end collision. It should be understood that the first preset safe distance threshold is less than the second preset safe distance threshold.
In summary, in the anti-collision reminding system provided in this embodiment, the anti-collision controller in the system can detect whether there is a collision risk between the two vehicles according to the distance information between the current vehicle and the vehicle behind the current vehicle detected by the distance detection device; further, when the collision risk is detected, the rear windshield is controlled to display the reminding message to remind a driver in a rear vehicle of paying attention to the driving distance, so that the driving safety is ensured, and the occurrence of rear-end accidents is reduced.
