Embodiment 1

[0024] figure 1 A schematic structural diagram of an automatic driving device provided in Embodiment 1 of the present invention is based on the fact that the automatic driving device has been installed in a vehicle, figure 1 A top view of the vehicle. like figure 1 As shown, the device includes: a solid-state lidar sensing module, a blind-filling radar sensing module, and a millimeter-wave radar sensing module.

[0025] Among them, the solid-state lidar sensing module includes one long-range solid-state radar 11 and eight medium-range solid-state radars 12 ; the blind-filling radar sensing module includes four blind-filling radars 13 ; the millimeter-wave radar sensing module includes two millimeter-wave radars 14 .

[0026] The long-range solid-state radar 11 is arranged on the front side of the central axis of the roof, and is used to detect information about obstacles in the middle and long distances directly in front of the vehicle. 8 mid-range solid-state radars 12 are...

Embodiment 2

[0034] Figure 5 is a schematic structural diagram of an automatic driving system provided by the second embodiment of the present invention, such as Figure 5 As shown, the system includes: an automatic driving device 210 , a data calibration module 220 , a data fusion module 230 , a first obstacle detection module 240 , a second obstacle detection module 250 , an obstacle classification module 260 and a target tracking module 270 .

[0035] Among them, the automatic driving device 210 is used to obtain the point cloud data of the surrounding environment of the vehicle; the data calibration module 220 is used to convert the point cloud data to the set coordinate system according to the calibration parameters; the data fusion module 230 is used for the converted point cloud. The data is synchronously fused in space and time; the first obstacle detection module 240 is used to analyze the fused point cloud data by using a deep learning model to obtain the first obstacle informat...

Abstract

The embodiment of the invention discloses an automatic driving device and system. Including: 1 long-distance solid-state radar, 8 medium-distance solid-state radars, 4 blind-filling radars and 2 millimeter-wave radars; the long-distance solid-state radar is set on the front side of the central axis of the roof, and is used to detect the mid- and long-distance vehicles in front of the vehicle. Obstacle information; 8 mid-range solid-state radars are respectively installed on the front of the roof, left front, right front, left side, right side, front rear, left rear, and right rear to detect 360° environmental information around the car body; 4 The blind-filling radars are respectively set above the front bumper, the rear bumper and the left and right fenders of the vehicle to scan the near-field blind area; two millimeter-wave radars are respectively set on the inside of the front bumper and the inside of the rear bumper to use for detecting moving obstacle information. All-round detection in the process of automatic driving can be realized, and the cost can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicles, and in particular, to automatic driving devices and systems. Background technique [0002] Autonomous driving technology is an important research direction of various research institutions and OEMs. In the development of autonomous driving, environmental perception technology is an important challenge. The main difficulty of this technology is how to quickly and accurately identify obstacles on the road. Since a single sensor often cannot accurately perceive the information of the surrounding environment of the vehicle, in order to ensure that the autonomous vehicle can collect the surrounding environment information in real time, efficiently and accurately, a variety of environmental sensing sensors are often equipped in autonomous driving. Millimeter-wave radar can work around the clock and has a long detection distance, but it is difficult to identify targets, and it is...
