Vehicle safety door opening protection system and control method thereof

Abstract

The invention discloses a vehicle safety door opening protection system. The system is provided with a control unit. The control unit acquires vehicle door lock state information, vehicle door opening and closing information, vehicle speed information, vehicle longitudinal deceleration information, transverse acceleration information and rear obstacle information collected by radar modules from a whole vehicle through CAN buses. The control unit outputs a control signal to vehicle door self-locking mechanisms. The control unit is in communication with an instrument control unit through a CAN bus to control a buzzer arranged in the instrument control unit to be started and stopped. According to the vehicle safety door opening protection system, randomness and nondeterminacy of drivers and passengers for understanding visual and audible alarming are overcome, the effectiveness of the system is improved, and the defects existing in an existing alarming manner are overcome; and in addition, the interference of visual and audible alarming reminding manners with the drivers and the passengers is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile active safety, in particular to a vehicle door opening anti-collision system and a control method. Background technique [0002] With the continuous improvement of users' demand for vehicles, the prominent role of automobile active safety technology in preventing accidents has attracted more and more attention. According to statistics, in vehicle accidents, due to drivers and occupants forgetting to look back to observe the rear vehicle conditions for a while, the traffic accidents caused by the collision of the rear approaching vehicle and the opened door due to sudden opening of the door account for about 6%. The vehicle door opening warning system is an active safety technology to avoid such accidents. At present, there are relatively few models equipped with the door opening warning system, and only a small number of imported high-end models have this configuration, and the danger reminder...

AI Technical Summary

Problems solved by technology

If the driver and occupant continue to open the door without understanding why the alarm signal is received, the system alarm will be invalid. At this time, the system cannot avoid the occurrence of collision accidents, especially for drivers and occupants such as the elderly or children. serious

This type of alarm method has a certain degree of randomness in conveying information to drivers and passengers, and cannot guarantee sufficient safety.
