相比现有技术，本发明创造的方案具有以下优点：Compared with the prior art, the scheme created by the present invention has the following advantages:
由于在汽车比如前方汽车的尾部安装了测速测距传感器及后部光学警示器，所述测速测距传感器及后部光学警示器均与一个中央控制器通讯连接，所述测速测距传感器设置成自动实时测量该前方汽车与后方汽车之间的距离及后方汽车相对于前方汽车的相对行驶速度，并且将距离和相对行驶速度的数据传输给所述中央控制器；所述中央控制器设置成：接收来自所述测速测距传感器传输的距离和行驶速度数据，然后判断所述距离是否大于预定的安全距离阈值，以及后方汽车的相对行驶速度是否大于预定的安全速度阈值，如果所述距离小于所述安全距离阈值并且所述后方汽车的相对行驶速度大于所述安全速度阈值，则所述中央控制器驱动所述后部光学警示器发光。因此只要后方汽车的相对行驶速度大于预定的安全行驶速度，并且前方汽车与后方汽车之间的距离小于安全距离，则后部光学警示器比如汽车刹车灯就会发出高光，进而对后方汽车司机形成强烈的视觉警示作用，尤其是，由于刹车灯高亮，给后方汽车司机形成了虚拟刹车效果，让后方汽车司机认为前方汽车进行了刹车动作，进而让后方汽车司机产生驾驶警觉作用，而潜意识里认为前方汽车在减速，最终促使后方汽车司机提高安全意思而可能减速行驶，从而避免了两车追尾的交通事故的发生，提高了行车安全度。Since a speed measuring and ranging sensor and a rear optical warning device are installed at the rear of the car, such as the car in front, the speed measuring and ranging sensor and the rear optical warning device are both connected to a central controller in communication, and the speed measuring and ranging sensor is set to Automatically measure the distance between the car in front and the car behind and the relative running speed of the car in front relative to the car in front, and transmit the data of the distance and relative running speed to the central controller; the central controller is set to: Receive the distance and driving speed data transmitted from the speed and distance sensor, and then determine whether the distance is greater than a predetermined safe distance threshold, and whether the relative driving speed of the vehicle behind is greater than the predetermined safe speed threshold, if the distance is less than the predetermined safe speed threshold. If the safe distance threshold is exceeded and the relative running speed of the rear vehicle is greater than the safe speed threshold, the central controller drives the rear optical warning device to emit light. Therefore, as long as the relative driving speed of the car behind is greater than the predetermined safe driving speed, and the distance between the car in front and the car behind is less than the safe distance, the rear optical warning device such as the brake light of the car will emit a high light, which will form a signal for the driver of the rear car. Strong visual warning effect, in particular, because the brake lights are highlighted, a virtual braking effect is formed for the driver of the rear car, so that the driver of the rear car thinks that the car in front has braked, and then the driver of the rear car has a driving alert effect, and subconsciously. It is believed that the car in front is slowing down, which ultimately prompts the driver of the rear car to improve safety and may slow down, thereby avoiding the occurrence of a traffic accident in which two cars collide and improving the driving safety.

As shown in the figure, the rear radar sensor 20 automatically measures the distance between the front car 100 and the rear car 200 and the relative driving speed of the rear car 200 relative to the front car 100 in real time (step S301 ), and compares the distance and the relative driving speed The speed data is transmitted to the central controller 10 (step S302); subsequently, the central controller 10 receives the distance and relative travel speed data transmitted from the rear radar sensor 20 (step S303), and then judges the distance Whether it is greater than a predetermined safe distance threshold, such as 100 meters, and whether the relative driving speed of the rear car 200 is greater than a predetermined safe speed threshold, such as 50 km/h (step S304), if the distance is less than the safe distance threshold and at the same time When the relative running speed of the rear vehicle 200 is greater than the safe speed threshold, the central controller 10 drives the rear optical warning device 30 to emit light (step S305 ). Otherwise, continue to return to step S301 to start over.
在本发明创造揭示的上述实施例中，由于在汽车比如前方汽车100的尾部安装了后雷达传感器20及后部光学警示器30，所述后雷达传感器20及后部光学警示器30均与一个中央控制器10通讯连接，所述后雷达传感器20设置成自动实时测量该前方汽车100与后方汽车200之间的距离及后方汽车200相对于前方汽车100的相对行驶速度，并且将距离和相对行驶速度的数据传输给所述中央控制器10；而所述中央控制器10设置成：接收来自所述后雷达传感器20传输的距离和相对行驶速度的数据，然后判断所述距离是否大于预定的安全距离阈值，以及后方汽车200的相对行驶速度是否大于预定的安全速度阈值，如果所述距离小于所述安全距离阈值并且所述后方汽车200的相对行驶速度大于所述安全速度阈值，则所述中央控制器10驱动所述后部光学警示器30发光。因此只要后方汽车200的相对行驶速度大于预定的安全行驶速度，并且前方汽车100与后方汽车200之间的距离小于安全距离，则后部光学警示器30比如汽车刹车灯就会发出高光，进而对后方汽车200司机形成强烈的视觉警示作用，尤其是，由于刹车灯高亮，给后方汽车200司机形成了虚拟刹车效果，让后方汽车200司机认为前方汽车进行了刹车动作，进而让后方汽车200司机产生驾驶警觉作用，而潜意识里认为前方汽车100在减速，最终促使后方汽车200司机提高安全意思而可能减速行驶，从而避免了两车追尾的交通事故的发生，提高了行车安全度。In the above-mentioned embodiment disclosed in the present invention, since the rear radar sensor 20 and the rear optical warning device 30 are installed at the rear of the car, such as the front car 100, the rear radar sensor 20 and the rear optical warning device 30 are both connected with one The central controller 10 is communicatively connected, and the rear radar sensor 20 is configured to automatically measure the distance between the front car 100 and the rear car 200 and the relative speed of the rear car 200 relative to the front car 100 in real time, and compare the distance and the relative driving speed. The speed data is transmitted to the central controller 10; and the central controller 10 is configured to: receive the distance and relative travel speed data transmitted from the rear radar sensor 20, and then determine whether the distance is greater than a predetermined safety distance threshold, and whether the relative travel speed of the rear car 200 is greater than a predetermined safe speed threshold, if the distance is less than the safe distance threshold and the relative travel speed of the rear car 200 is greater than the safe speed threshold, the center The controller 10 drives the rear optical warning device 30 to emit light. Therefore, as long as the relative driving speed of the rear car 200 is greater than the predetermined safe driving speed, and the distance between the front car 100 and the rear car 200 is smaller than the safe distance, the rear optical warning device 30, such as the brake light of the car, will emit a high light, and furthermore The driver of the car behind 200 forms a strong visual warning effect. In particular, because the brake lights are highlighted, a virtual braking effect is formed for the driver of the car behind 200, so that the driver of the car in the rear 200 thinks that the car in front has performed a braking action, and then the driver of the car in the rear 200 is made. It generates driving alertness, and subconsciously thinks that the car 100 in front is slowing down, and finally prompts the driver of the car 200 behind to improve safety and may slow down, thereby avoiding the occurrence of traffic accidents where two cars collide and improving driving safety.
优选地，在本技术方案中，除了采用上文提到的后雷达传感器之外，还可以使用红外传感器、激光探测器等测速测距传感器，其均在本发明创造考虑的范围内。Preferably, in this technical solution, in addition to the rear radar sensor mentioned above, speed measuring and ranging sensors such as infrared sensors and laser detectors can also be used, which are all within the scope of the invention.
