The embodiment of the utility model provides a car distance display system and car shows this car speed of a motor vehicle, with back car distance through the display screen behind this car for back car owner obtains effective information and makes the exact feedback, and the effectual accident of knocking into the back of initiative avoidance vehicle.

As shown in fig. 1, an embodiment of the present invention provides a vehicle distance display system for an automobile, including:

the display screen 1 is mounted below rear glass of the automobile;

the system comprises at least three distance measuring radars, a first sensor and a second sensor, wherein the three distance measuring radars are respectively arranged on a bumper of an automobile;

the vehicle speed detection module 6 is arranged in an anti-collision beam of the automobile and is positioned between two adjacent distance measuring radars;

and the controller 5 is connected with each ranging radar, the vehicle speed detection module 6 and the display screen 1 respectively, is installed in an anti-collision beam of the automobile for measuring, and is positioned between two adjacent ranging radars.

It should be noted that, the display screen 1 of the present invention is installed below the rear glass of the automobile, when the automobile is running, the rear vehicle can judge according to the content of the display screen 1, so as to reduce the occurrence of rear-end collision accidents; the vehicle speed detection module 6 and the controller 5 are both arranged on the inner side of an anti-collision beam of the automobile for the purpose of protecting devices and connected lines.

Specifically, at least three range radars are equidistantly installed on the bumper of the automobile and are sequentially arranged along the length extending direction of the bumper.

Here, three range radar monitors the trilateral driving signal in left side, middle and right behind the car respectively, connects through the bolt mode of punching, guarantees its fastening nature.

Further, the vehicle speed detection module 6 is disposed between the adjacent first and second ranging radars 2 and 3, and the controller 5 is disposed between the adjacent third ranging radar 4 and the second ranging radar 3.

Specifically, the display screen 1 is an LED display screen.

Specifically, the controller 5 at least comprises a radar signal processing circuit, a vehicle speed signal processing circuit and a display control circuit;

the radar signal processing circuit is electrically connected with each ranging radar;

the vehicle speed signal processing circuit is electrically connected with the vehicle speed detection module 6;

the display control circuit is electrically connected with the display screen 1.

As an embodiment, the specific work flow of the vehicle distance display system is as follows:

when the automobile moves, the automobile speed detection module 6 is started to monitor the current automobile speed, and the controller 5 displays the current automobile speed to the lower part of the rear glass of the automobile through the display screen 1; and further, starting at least three distance measuring radars, wherein when a detector in each distance measuring radar detects whether an obstacle exists on a route behind the automobile, if no obstacle exists, only the current speed of the automobile is displayed on the display screen 1, and if no obstacle exists, the detector in each distance measuring radar detects and calculates the relative distance between the obstacle and the automobile. For example, data of the detected obstacle position information, the signal transmission time, the return time, and the like are transmitted to the controller 5 in the automobile.

Here, the controller 5 compares the relative distance with a preset safety distance, determines the kind of safety class of the relative distance according to the comparison result, and configures different display colors for different kinds of safety classes; in the display screen 1, the relative distance between the obstacle and the automobile and the current speed of the automobile are presented in configured display colors.

As an example, assume that the preset safety distance includes: a first distance range corresponding to the danger level and a second distance range corresponding to the safety level, wherein the first distance range is smaller than the second distance range; when the calculated relative distance is within the first distance range, displaying the relative distance in red in the vehicle distance display area; when the calculated relative distance is within the second distance range, the relative distance is displayed in green in the inter-vehicle distance display area. For example, the distance of the danger level is 1.0 m or less, the distance of the safety level is more than 1.0 m, and when it is detected that the relative distance is less than 1.0 m, the controller 5 controls the display screen 1 to display the relative distance between the obstacle and the vehicle and the current vehicle speed of the vehicle using a red font. Further, when the relative distance between the automobile and the obstacle changes, the display color in the display screen 1 changes accordingly.

An embodiment of the utility model provides a car is still provided, include as above car distance display system.
