Abstract

The invention provides a vehicle adaptive blind area monitoring system based on ultrasonic wave, which comprises an ultrasonic radar arranged at a rear part of the vehicle in a straight traveling direction, wherein the ultrasonic radar detects the number of water droplets in a preset distance range in a preset time at the rear of the vehicle; the ultrasonic radar detects the number of water droplets in a preset distance range in a preset time range. A controller is connected with the ultrasonic radar, and the controller controls the operation of the blind area monitoring system according to the number of water droplets detected by the ultrasonic radar. The invention utilizes ultrasonic radar to detect the water droplet quantity behind the vehicle, the controller controls the work of the blind area monitoring system according to the number of water droplets, Form a feedback mechanism, The blind area monitoring system can be corrected in time. The blind area monitoring system is not affected by the humidity to the detection stability of ultrasonic radar, so it can reduce the false alarm rate of the blind area monitoring system in rainy environment. Compared with millimeter wave radar, it can not only ensure the user driving experience, but also reduce the cost, which is conducive to production.

Description

technical field [0001] The invention relates to the technical field of automobile intelligence and active safety, in particular to an ultrasonic-based vehicle self-adaptive blind spot monitoring system. Background technique [0002] With the rapid development of science and technology, the technology on cars has also developed by leaps and bounds. With the development of science and technology and the needs of people, the blind spot detection system (BSD: Blind Spot Detection) came into being. Due to the visual blind spot in the car rearview mirror, the vehicle in the blind spot cannot be seen before changing lanes. If there is an overtaking vehicle in the blind spot, At this time, a collision accident will occur when changing lanes. In heavy rain, fog, and dim light at night, it is even more difficult to see the vehicles behind. At this time, changing lanes is more dangerous. The main function of the blind spot monitoring system is to eliminate the blind spot of the rearv...
