The invention discloses a vehicle safety auxiliary system for lane changing. The vehicle safety auxiliary system comprises a video acquiring unit, an echo sensing unit, a processing unit and a display unit. The video acquiring unit acquires an image of the road after the vehicle. The echo sensing unit detects whether or not an obstacle vehicle drives in the dead zone on the rear side of the vehicle. According to the echo sensing unit, the processing unit judges whether or not the obstacle vehicle drives in the dead zone to directly affect merging or lane changing of the vehicle, if yes, sends alarms or locks a steering wheel to prevent the driver from merging or changing lanes, if no obstacle vehicle is detected to drive to directly affect the vehicle to merge, the image is acquired by the video acquiring unit and analyzed, and whether or not the vehicle drives at the back is judged; if yes, the distance between the vehicles and the relative speed are calculated; according to the distance and the relative speed, the safety level of the lane changing is estimated. The display unit arranged on a rear view mirror displays the safety level of the lane changing, accordingly helping the driver change lanes.
