Embodiment Construction
[0027] like figure 1 The method shown in the process of the present invention is schematically showing this automatic brake method provided by the present invention, including the following steps:
[0028] S1. Video data information of the surrounding environment is obtained through a number of network cameras (preferably 3 channels);
[0029] S2. According to the video data information acquired by step S1, it is determined whether there is an obstacle in the surrounding environment; specifically, it is calculated using the artificial intelligence algorithm to determine whether the surrounding environment has an obstacle: obtaining a number of network camera's video data information as input, pair The dynamic weight score is performed after the dynamic weight score is performed; and then the total score is obtained by the set excitation function to obtain a neuron output; and then bonded by multiple neurons to obtain the final surrounding environment. Obstacle Judgment information...

The invention discloses an automatic braking method, which includes obtaining video data information of the surrounding environment through several network cameras; judging whether there are obstacles in the surrounding environment; and combining point cloud data obtained by several laser radar sensors according to the judged obstacle information Calculate the obstacle distance and angle of the surrounding environment; obtain the driving data of the current vehicle; calculate the braking force of the current vehicle according to the driving data of the current vehicle and the obstacle distance and angle of the surrounding environment to complete the automatic braking of the vehicle. The invention also discloses an automatic braking device for realizing the automatic braking method, and an automatic driving vehicle including the automatic braking method and the automatic braking device. The automatic braking method, automatic braking device and automatic driving vehicle provided by the present invention can accurately calculate the position and distance of obstacles in the surrounding environment, and automatically control the braking of the vehicle, with high reliability, high accuracy and stability. it is good.
Description
Technical field [0001] The present invention belongs to the automatic driving area, and more particularly to an automatic brake method, an automatic brake device, and its automatic driving vehicle. Background technique [0002] With the development of economic technology and the improvement of people's living standards, automatic driving technology has been widely used in people's production and life, bringing endless convenience to people's production and life. [0003] Automatic brakes are an important part of automatic driving technology that assumes automatically stopping the vehicle. Therefore, the automatic brake has become one of the most important parts in automatic driving technology. [0004] Current automatic brake technology, generally adopted technical solutions are: vehicles detect barriers to vehicles through millimeters or ultrasonic radar. When there is obstacles in the vehicle driving direction, the driver or active brakes will be prompted to prevent the vehicle...
