Danger auxiliary system of lane changing blind zone

Abstract

The invention provides a danger auxiliary system of a lane changing blind zone, and belongs to the field of vehicle safety. The danger auxiliary system comprises a side front radar sensor, a side rear radar sensor, a central controller and a vehicle-mounted ECU execution unit, wherein the side front radar sensor is used for detecting vehicle side front road environment information and vehicle information and distance information from a vehicle side front road vehicles to a self-vehicle and transmitting the information to the central controller; the side rear radar sensor is used for detecting vehicle side rear road environment information and vehicle information and distance information from a vehicle side rear road vehicles to the self-vehicle and transmitting the information to the central controller; the central controller receives the transmission information and the self-vehicle information of the side front radar sensor and the side rear radar sensor, judging whether lane changing is dangerous or not and sending instructions to the relevant vehicle-mounted ECU execution unit; and the vehicle-mounted ECU execution unit receives instructions of a processing unit and executes the instructions. The danger auxiliary system of the lane changing blind zone can solve the problem that an existing blind spot monitoring system cannot avoid collision risk of crossing of vehicles or quick close vehicles in the blind zone due to the fact that the vehicles or quick close vehicles in the blind zone are not detected.

Description

technical field

[0001] The invention relates to the field of vehicle safety, in particular to a lane-changing blind zone danger assisting system. Background technique

[0002] Collisions due to the existence of blind spots when vehicles change lanes are one of the most common types of accidents on expressways in my country. Collision accidents caused by lane changes endanger the life and property safety of traffic participants, and also cause a series of social problems, so they have received extensive attention from insurance associations, automobile manufacturers, and scientific research institutions.

[0003] At present, major automobile OEMs at home and abroad have applied the blind spot detection function based on ultrasonic radar to a large number of models. When the vehicle enters the blind spot of the car, it will give an alarm to the car. In 2014, a small number of models launched in 2014 are equipped with millimeter-wave radar. Lane-changing warning function, when...
