Vehicle rearview mirror dead zone detection system and vehicle rearview mirror

Abstract

The invention discloses a vehicle rearview mirror dead zone detection system and a vehicle rearview mirror. The vehicle rearview mirror dead zone detection system is a set of independent monitoring system. A radar sensor detects whether a moving object exists in a dead zone or not, when the moving object is monitored, the distance of the moving object to the vehicle and the driving speed of the vehicle are then automatically judged, when the distance is lower than 15 meters or the speed is higher than 20 km / h, an indicating lamp is controlled to be turned on, when the radar sensor detects that a vehicle steering light signal for facing the moving object exists, the indicating lamp is controlled to flicker, and a driver is then further reminded of the dangerousness of steering. The whole process is fast and simple, meanwhile, a vehicle main controller can also call signals of the radar sensor so as to conduct alarming of an interior alarming module, the driver is further prompted when in danger, thus the occurrence of collision accidents when the vehicle changes lanes or makes a turn is avoided, and thus driving vehicle is safer.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to an automobile rearview mirror blind area detection system and an automobile rearview mirror equipped with the automobile rearview mirror blind area detection system. Background technique [0002] When a car needs to change lanes or turn, the driver often checks the rearview mirror to determine the driving status and position of the car coming from behind, so as to determine whether the lane change or turn can be implemented. However, the current rearview mirrors are all made of curved glass. Due to the limitation of the curvature of the rearview mirror glass, when the position of the vehicle coming from behind is only half the length of the vehicle from the position of the vehicle in front, the image of the rear vehicle just falls into the rear view mirror. In the visual blind spot of the mirror, the driver cannot see the car behind. At this time, if changin...

AI Technical Summary

Problems solved by technology

However, the current rearview mirrors are all made of curved glass. Due to the limitation of the curvature of the rearview mirror glass, when the position of the vehicle coming from behind is only half the length of the vehicle from the position of the vehicle in front, the image of the rear vehicle just falls into the rear view mirror. In the visual blind spot of the mirror, the driver cannot see the car behind. At this time, if changing lanes or turning, side collision accidents are very likely to occur

In heavy fog, heavy rain and snowy weather, the rearview mirror lens is blurred, and if you change lanes or turn at this time, it is very easy to find a side collision accident
