Problems solved by technology
[0008] If the system cannot lock the pedestrian target, the car will not trigger the pedestrian protection function, resulting in a collision
[0009] If the system locks on pedestrians late, although the car can trigger the pedestrian protection function, it can intelligently slow down the collision and cannot avoid collisions

Embodiment Construction
[0067] The pedestrian AEB system is based on the reflection feature information of the object ahead collected by the millimeter wave radar and the image information of the object collected by the forward-looking camera to calculate the obstacle type and the degree of collision risk, and then trigger the pedestrian when the attribute and danger degree of the obstacle exceed the calibration threshold. AEB function. Based on the current status of camera and millimeter-wave radar technologies and their respective functional limitations, the embodiments of the present application provide a technical solution for controlling the pedestrian protection function of the pedestrian AEB system when a pedestrian is detected during the automatic driving of the vehicle. The scheme can realize the trigger control of the vehicle's pedestrian AEB system by judging whether there are interference objects in the left and right lanes in front of the vehicle, and using different control logics. like...

This solution relates to a driving control method, a pedestrian AEB system, an intelligent driving vehicle, a controller and a computer-readable storage medium, which can solve the problem that the AEB function is not triggered due to obstructions on both sides of the road and vehicle interference in traffic jams and traffic jams. , the method includes: monitoring the actual traffic situation ahead through a camera, and classifying the traffic situation ahead into: no interference, unilateral interference, and bilateral interference. The millimeter-wave radar is used to obtain the RCS value of the forward environmental reflection characteristics and set different target trigger thresholds in the pedestrian AEB system for different scenarios. When there is a pedestrian crossing in front of the vehicle, the pedestrian AEB system selects the corresponding trigger according to the current traffic scene. Threshold, when there is a collision risk and the calculated collision probability exceeds the target trigger threshold, the pedestrian protection function of the pedestrian AEB system is triggered to maximize the safety of vehicles and pedestrians' lives and properties.
Description
technical field [0001] The invention belongs to the field of automobile intelligent driving, and particularly relates to a driving control method, a pedestrian AEB system, an automobile, a controller and a computer-readable storage medium. Background technique [0002] With the rapid development of automotive active safety, pedestrian AEB systems have been widely used in various car models. As one of the active safety functions of the intelligent driving assistance system, the pedestrian AEB function has also become synonymous with high-end or high-end models of all models. With the popularization of the pedestrian AEB function, the scenarios it faces are becoming more and more complex, and the driver and road participation are increasingly dependent on the pedestrian AEB system. [0003] For the L2-level intelligent driving assistance system, the main application scenarios of the pedestrian AEB system are urban roads and rural roads. The distinctive features are that ther...
