Problems solved by technology

The existing technology relies on infrared camera machine vision to perceive pedestrians. Because of the error in determining the distance of the camera, it is easy to cause inaccurate determination of the distance and speed of pedestrians, resulting in inaccurate active braking intervention for vehicles to start pedestrian collision avoidance. Lead to bad user experience and feeling

Abstract

The invention discloses a design method for active brake pedestrian collision prevention. A forward millimeter wave radar, a forward looking infrared camera, a control module and an actuator are included. The millimeter wave radar is used for probing the longitudinal distance and the relative speed of a forward target object and a vehicle. The forward looking infrared camera is used for classifying the target object, conducting final confirmation on pedestrians, and meanwhile probing the transverse distance and the relative speed of the pedestrians and the vehicle. The control module is used for logical calculation and algorithmic processing. The actuator mainly executes the active brake function of the vehicle. According to the design method for active brake pedestrian collision prevention, through fusion processing of the forward looking infrared camera and the millimeter wave radar, the relative distance and orientation of the pedestrians and the vehicle are judged by a system moreprecisely, so that the phenomena such as mistaken starting and non-starting of pedestrian collision prevention active brake of the vehicle are avoided, and meanwhile, the user experience and feeling are also improved.

Description

technical field [0001] The invention relates to the field of safety protection, in particular to a design method for actively braking pedestrians to avoid collisions. Background technique [0002] In the vehicle's active safety system, there is a pedestrian anti-collision active braking function based on machine vision. The main solution is to use camera machine vision to solve it. However, the camera machine vision is not accurate enough to judge the longitudinal distance and relative speed of pedestrians, which can easily lead to misjudgment and cause the vehicle's active braking function to be activated by mistake. At the same time, the vision of the camera is greatly affected by weather factors, especially in dim light conditions, and pedestrians cannot be correctly identified. [0003] Existing technical solutions include: camera-based machine vision processing, using infrared sensors to perceive pedestrian paths and relative vehicle positions. (An automatic infrared ...
