Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] Such as figure 1 with 2 Shown is a graded lighting brake warning taillight based on vehicle radar, which includes two groups of strip taillights arranged symmetrically in the middle, upper or middle and lower positions of the rear windshield of the vehicle. Composed of three LED lamp holders, the LED lamp holders are evenly divided into 3 warning units according to the column, which are the first-level warning unit, the second-level warning unit and the third-level warning unit, and all the LED lamp holders in each warning unit. Switch control, so the LED lights in the same warning unit ca...

Abstract

The invention discloses a graded lighting type braking warning tail lamp based on a vehicle-mounted radar. Strip-shaped tail lamps are divided into three warning units, switches of the warning units are connected with an ECU, and the ECU is connected with a vehicle-mounted speed sensor and the vehicle-mounted radar separately. The speed of a vehicle, the speed of a rear vehicle and the azimuth angle and distance between the rear vehicle and the vehicle are obtained through the vehicle-mounted speed sensor and the vehicle-mounted radar, the braking warning distance Lmax is obtained according tothe speed of the vehicle and the speed of the rear vehicle, whether the rear vehicle and the vehicle are located on the same lane or not is judged according to the azimuth angle and distance betweenthe rear vehicle and the vehicle, and the ECU calculates the vehicle distance difference ratio i according to the braking warning distance Lmax and the distance L between the two vehicles and then lightens the warning units in a graded manner according to the vehicle distance difference ratio i to complete graded lighting and graded warning of the strip-shaped tail lamps.

Description

technical field [0001] The invention belongs to the field of active safety of intelligent traffic systems, in particular to a graded lighting brake warning tail light based on vehicle radar. Background technique [0002] Although the global vehicle industry has been relatively sluggish in recent years, and car sales have dropped sharply, the pace of rapid economic growth has never stopped, and people's pursuit of high-quality life has never stopped. , and its holdings are still increasing. Similarly, there are a series of traffic safety issues that follow, which have always been highly valued by the government and society. According to incomplete statistics, among many types of traffic accidents, rear-end collisions account for nearly half of them. A large number of studies have shown that in rear-end collisions, if the driver of the vehicle behind can receive a reminder one second before taking braking measures, 90% of accidents can be effectively avoided. Therefore, it ...
