A control method for frequent multi-vehicle alarms in blind spots

Abstract

The invention relates to the technical field of blind spot monitoring, in particular to a method for controlling frequent multi-vehicle alarms in the blind spot. Including judging the lateral distance between the target vehicle and the vehicle; if there are multiple target vehicles in the alarm area, and the lateral distances from the vehicle are all within the set first warning range, and the alarm state has not changed , carry out the first-level beep alarm and the first-level instrument alarm; the output of the first-level beep alarm reaches the set first duration; the first-level instrument alarm continues to output until the last target vehicle within the first warning range drives out Alarm area. It can effectively prevent frequent alarms on road sections with many vehicles, and at the same time, can obtain complete early warning information by paying attention to the instrument to ensure driving safety.

Description

A control method for frequent alarming of multiple vehicles in blind area technical field [0001] The present invention relates to the technical field of blind spot monitoring, and in particular to a method for controlling frequent alarms for multiple vehicles in a blind spot. Background technique BSD blind spot detection system (Blind Spot Detection System) is used for monitoring to be in inside and outside rearview mirror view Detect moving objects (such as cars, motorcycles, bicycles, pedestrians) behind the blind spot, and detect whether there is a target behind the adjacent lane The body is approaching, and whether there is a target object in the blind spot of the rearview mirror. When the target object approaches the vehicle, according to the danger and emergency It sends out sound, light and other signals in a timely manner to assist the driver to avoid objects in the blind spot and achieve the purpose of safe merging. [0003] The current BSD system generally h...
