Vehicle safety auxiliary system for lane changing

Abstract

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.

Description

technical field [0001] The invention relates to a vehicle to which the vehicle safety lane-changing auxiliary system has been applied. Involving patent classification B60 General vehicles B60R Vehicles, vehicle accessories or vehicle parts not included in other classes B60R21 / 00 On-vehicle devices or accessories for protecting or preventing injuries to passengers or pedestrians in the event of accidents or other traffic hazards B60R21 / 01 Circuit B60R21 / 013 that triggers safety protection devices in the event of a vehicle accident or imminent accident contains devices for detecting a collision, imminent collision or rollover. Background technique [0002] With the development of automotive electronic technology, the active safety technology of vehicles has also made great progress. At present, various safety assistance driving systems have emerged as the times require. In the actual driving process, when changing lanes, the driver needs to use the interior and exterior rear...
