Problems solved by technology

However, when the vehicle is turning, there is a camera blind spot due to the limitation of the shooting angle of the traditional camera, which will affect the detection of obstacles on the curve by the active safety system
In order to eliminate the camera blind spot when the vehicle is turning, it can be solved by arranging multiple cameras, but the cost will increase significantly

Embodiment Construction

[0040] This embodiment provides a method for increasing vehicle cornering safety, including: step 1, the steering wheel angle sensor 30 detects in real time whether a steering wheel angle signal including whether the vehicle enters a curve and the vehicle turns is received. Step 2, after receiving the steering wheel angle signal, the BCM controller 40 obtains the original shooting angle and the original shooting range of the camera on the vehicle, and calculates the rotation angle of the camera 60 required to eliminate the shooting blind spot and / or adjusted shooting range A. Step 3, the stepping motor 50 drives the camera 60 to rotate with the rotation angle φ to change the original shooting angle of the camera 60; and / or the stepping motor 50 adjusts the original shooting range of the camera 60 to be the adjusted shooting range A, to The shooting blind spot of the camera 60 is eliminated. The invention enables a single camera to eliminate shooting blind spots by changing t...

Abstract

The invention provides a method and a system for increasing a vehicle cornering safety. The method for increasing the vehicle cornering safety includes the below steps: step 1, a sensor of a steering wheel angle detects the signal of the steering wheel angle in real time; step 2, after receiving the signal of the steering wheel angle, BCM (body control module) controller obtains an original shooting angle and an original shooting range and calculates a required rotation angle Phi to eliminate the shooting blind spots and / or an adjusted shooting range A ; step 3, a stepper motor driver camera rotates in a rotation angle Phi, and / or the original shooting range is adjusted as the adjusted shooting range. The BCM controller of the invention obtains the original shooting angle and the original shooting range and calculates the required rotation angle Phi to eliminate the shooting blind spots and / or the adjusted shooting range A; the stepper motor rotates in a rotation angle Phi by the driver camera or changes the original shooting angle or / and the original shooting range of a single camera and eliminates shooting blind spots of the single camera by adjusting the focal length of the camera.

Description

technical field [0001] The invention relates to the field of vehicle active safety, in particular to a method and system for increasing vehicle cornering safety. Background technique [0002] With the development of electronic sensing technology, cameras are widely used as environmental sensors in vehicle active safety systems, such as automatic emergency braking for pedestrians (AEB-P), lane departure warning (LDW), etc. By developing different algorithms, the camera arranged on the front windshield of the vehicle can be used to identify vehicles, pedestrians, bicycles, animals, etc. in front. However, when the vehicle is turning, there is a camera blind spot due to the limitation of the shooting angle of the traditional camera, which will affect the detection of obstacles on the curve by the active safety system. In order to eliminate the camera blind spot when the vehicle is turning, it can be solved by arranging multiple cameras, but the cost will increase significantly...
