Vehicle safety control system and method for lane line detection temporary loss in automatic drive

Abstract

The invention discloses a vehicle safety control system and method for lane line detection temporary loss in automatic drive, and the system comprises an automatic drive decision-making module, an image processing module, a light controller, an execution mechanism, an HMI module and a camera, wherein the image processing module, the light controller, the execution mechanism and the HMI module are respectively connected with the automatic drive decision-making module, and the camera is connected with the image processing module. The image processing module carries out the processing of an image, and carries out the detection of a lane line. The automatic drive decision-making module carries out the planning of a driving path of a vehicle based on the lane line, and controls the running of the vehicle. When the image processing module cannot detect the lane line, the automatic drive decision-making module obtains a passable region of a road according to a historical track of the vehicle and the information detected by a radar group, and controls the vehicle to reduce the speed and run in the passable region, and the light controller turns on an emergency light, and the HMI module continuously reminds a driver of taking charge of the vehicle. When the lane line cannot be detected in a short time, the system can guarantee that the vehicle is in a safety state, and guarantees the safety of the driver.

Description

technical field [0001] The invention belongs to the technology of automatic driving, and in particular relates to a vehicle safety control system and method for transient loss of lane line detection during automatic driving. Background technique [0002] The highway automatic driving system is an automatic driving system for highway structured roads. On the main road of the highway, the lane line is detected through the cooperation of the front-view camera and the image processing module to determine the relative position of the vehicle and the lane line, so as to control The steering wheel drives along the lane line or switches roads; and detects the traffic environment around the vehicle through the radar sensors around the vehicle body, so as to confirm the safety status. [0003] However, if the lane lines on the road are incomplete or the light is insufficient, the image processing module cannot detect the lane lines from the images collected by the camera. If the lane ...

Problems solved by technology

[0003] However, if the lane lines on the road are incomplete or the light is insufficient, the image processing module cannot detect the lane lines from the images collected by the camera. If the lane lines cannot be detected, the automatic driving system cannot plan the driving path of the vehicle. The driver is required to take over the vehicle at any time, but if the driver does not pay attention to the driving behavior, the driver will not be able to respond to the vehicle's reminder in time, but the automatic driving system will exit directly, which will inevitably lead to unnecessary traffic accidents
