Side collision avoidance device and side collision avoidance method for large vehicle when turning

Abstract

The invention discloses a side anticollision device and a side anticollision method when a large-sized car turns a corner. The side anticollision device comprises a central processing unit, a car detection unit, an intersection barrier detection unit, an alarm display unit and a safety device trigger, wherein a car speed sensor and the intersection barrier detection unit are started according to a cornering signal of a steering wheel detected by the car detection unit, and a corresponding area of difference of radius between inner wheels is calculated according to the intersection information and the car speed detected by the intersection barrier detection unit; whether a barrier stays in the area of the difference of radius between inner wheels or not according to the detected barrier information, the car is controlled to start the safety device and issue an alarm when car and other vehicles or pedestrians stay in the area of the difference of radius between the inner wheels or other vehicles or pedestrians can reach the area of the difference of radius between the inner wheels when the car turns t corner according to the speed sensor, a prompted driver takes measures to avoid the accident or reduce the injury in collision between the car and other vehicles or between the car and pedestrians.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a side anti-collision device and a side anti-collision method when a large automobile turns. Background technique [0002] At present, in the accidents that large-scale vehicles take place, most accidents take place when large-scale vehicles turn. The bodies of large vehicles such as large trailers, muck trucks, and cement tank trucks are relatively long. When turning, the inner rear wheels do not completely follow the track of the inner front wheels, and there will be a certain deviation. The deviation caused by turning is called " Inner wheel difference", such as figure 1 shown. The area where this "inner wheel difference" is located cannot be observed by the driver. Therefore, most of the accidents are caused by pedestrians or vehicles in the "inner wheel gap" area. The inner wheel gap often occurs after the front of the car is turned, and there is still a long body that ha...

AI Technical Summary

Problems solved by technology

Its shortcoming is that this device only considers the side collision avoidance problem when changing lanes or slowing down or parking and opening the door, and does not consider the local existence of "inner wheel difference" when the vehicle is turning, especially when the large car is turning. is the main factor leading to vehicle collisions
