Description

Anti-rear collision reminder system

technical field

The utility model relates to the technical field of automobile safety, in particular to an anti-rear-end collision warning system. 

Background technique

When the car is running, the driver judges the distance between his vehicle and the vehicle behind him through the exterior rearview mirror and the interior rearview mirror. When the daylight is sufficient, the driver's judgment is usually more accurate. However, when driving at night, due to the lack of light, the driver's vision is weakened, and the influence of the lights of the rear vehicle is added. If the driver judges the distance of the rear vehicle through the interior and exterior rearview mirrors, it is easy to produce a large deviation, or When driving under severe weather conditions such as rain, snow, and heavy fog, the driver's vision is poor, and the inner and outer rearview mirrors often lose their effect, especially when driving on the expressway at night or in bad weather conditions, the vehicle speed is high, The driver's attention is focused on the front view, and the deviation of the driver's distance judgment is more serious, which leads to more traffic accidents. the

Chinese patent authorization announcement number: CN 2841420Y, on November 29, 2006, discloses a kind of automobile external rearview mirror, belongs to the field of automobile technology. The present invention solves the defects of poor connection firmness, complex structure, and inability to provide drivers with a sufficient range of viewing angles for existing automobile rearview mirrors. The seat is connected with the casing, and the lens is arranged in the casing, and it is characterized in that the lens is composed of a plane mirror and a convex mirror connected together, and after the rearview mirror is installed on the vehicle body, the convex mirror is located outside the plane mirror . The disadvantage is that when using the rearview mirror of this utility model, when driving at night or in bad weather such as rain, snow, and heavy fog, it is difficult for the driver to judge the distance between the vehicle behind and his own vehicle, so it is easy to Judgment deviations cause traffic accidents, endangering the lives of drivers and passengers in the car.

Utility model content

The utility model aims at overcoming the disadvantages in the prior art that when the driver judges the distance between the vehicle and the rear vehicle through the vehicle rearview mirror due to poor light or bad weather, it is easy to cause traffic accidents, and provides a vehicle that can display The distance from the vehicle behind is also prompted to the driver, which is an anti-rear-collision reminder system that is convenient for the driver to control the distance between vehicles. ``

In order to achieve the above object, the utility model adopts the following technical solutions:

The utility model relates to an anti-rear-end collision warning system, which includes a distance measuring unit for measuring the distance of the rear vehicle, a control analysis unit and a display unit for displaying the distance of the rear vehicle, the control analysis unit is connected with the display unit, and the A switch is provided between the distance measuring unit and the control analysis unit. When there is a vehicle behind, the distance measuring unit can measure the distance between the vehicle behind and the vehicle, and transmit the information to the control analysis unit, and the control analysis unit calculates the distance information, and displays the distance information of the vehicle behind through the display unit In this way, the driver can easily understand the distance between the vehicle behind and the vehicle, and the driver can take appropriate measures to control the distance between vehicles according to the displayed information. Therefore, in the case of insufficient light at night, or in the case of bad weather and low visibility, the system can provide the driver with accurate distance information of the vehicles behind, which is convenient for the driver to control the distance between vehicles.

As a preference, the control analysis unit is also connected with double flashing lights. In the control analysis unit, a dangerous range can be set for the distance between the vehicle behind. When the distance between the vehicle and the vehicle behind is within this dangerous range, the control analysis unit can control the double flashing lights to light up and flash to remind the driver of the vehicle behind. Pay attention to keep the distance between cars.

Preferably, the distance measuring unit and the control analysis unit are connected with a compass module through a switch. The driver can switch the display unit between displaying the compass or displaying the distance between vehicles by switching the switch according to his own wishes, so as to meet different needs.

Preferably, the distance measuring unit is an infrared radar installed at the rear of the vehicle. Infrared radar is installed at the rear of the car to facilitate distance measurement.

Preferably, the display unit is arranged on the left side of the surface of the interior rearview mirror, and the switch is arranged on the lower left side of the interior rearview mirror. The display unit is set on the left side of the interior rearview mirror, and the driver can know the vehicle distance information at any time. It is also more convenient to use the toggle switch to switch and display the vehicle distance or compass information.

Therefore, the utility model has the following beneficial effects: (1) the driver of the vehicle can be provided with the vehicle distance information of the vehicle behind; (2) when the vehicle distance is too close, the driver of the vehicle behind can be reminded to keep the vehicle distance; (3) It can switch between displaying vehicle distance and compass to meet different needs of drivers.
