Vehicle radar system for automatic driving

Abstract

The invention relates to the technical field of unmanned vehicles, and discloses a vehicle-mounted radar system for automatic driving of vehicles, which includes a vehicle roof and a laser ranging radar, and a hydraulic telescopic rod is fixedly installed on the upper surface of the vehicle roof. The vehicle-mounted radar system for automatic driving of the car is provided with a connecting chute on the side wall of the inner ring of the base, and fixedly installed on both sides of the connecting seat installed at the bottom of the laser ranging radar. Rotate in the connecting chute. When the rotation reaches the maximum angle, the laser ranging radar will fall into the vertical groove at the bottom of the connecting chute. At this time, the pressing block is pressed down by twisting the threaded rod, so that the pressing block is tightly pressed. Hold the clamping block to realize the fixing of the clamping block. This fixing method is simple and easy to operate, and this fixing method does not use any professional fixing tools. It is more convenient, quick and easy to operate when disassembling, maintaining or replacing the laser ranging radar. .

Description

technical field [0001] The invention relates to the technical field of unmanned vehicles, in particular to a vehicle-mounted radar system for automatic driving of vehicles. Background technique [0002] Driverless car is a new type of intelligent car, which automatically controls the position and speed of the car on the road through the computer system installed in the car and the radar detection system, and the radar detection system includes the laser ranging radar on the top of the car And the on-board radar installed around the car. The laser ranging radar on the top detects the position and speed of obstacles by emitting laser beams. It is a device that can accurately and quickly obtain three-dimensional space information on the ground or the atmosphere. Whether the device is The normal work will directly affect the normal work of the entire automatic driving system, and the existing roof laser ranging radar always has some problems in use: [0003] 1. The existing roo...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing roof laser ranging radar needs to collect data from the three-dimensional environment around the car, so the radar is fixedly installed on the iron frame by fixing the bottom of the radar on the iron frame, and then the iron frame is fixed and installed On the roof, so as to realize the fixing of the radar, this fixing method requires professional fixing tools and the fixing method is complicated, and the radar needs to be regularly fixed because it is exposed to the air for a long time and works with the high-speed car for a long time. It needs to be replaced when it is maintained and damaged. The existing fixing method is complicated and inconvenient when it is necessary to disassemble the radar for maintenance or replacement under the above circumstances.

[0004] 2. The existing laser ranging radar installed on the roof can realize data collection in a three-dimensional environment within a diameter of 150 meters centered on the car, and the laser radar can also adjust the angle of the beam in the vertical direction to realize the Cars collect data in close-range and long-distance environments, but the existing laser ranging radars are fixedly installed on the roof, and the radar cannot move in the vertical direction, and the angle adjustment can only be done through the laser ranging radar Self-adjustment, so that the adjustment range of the radar is limited, especially when the car is running at a slow speed, the environment on each side of the car is more complicated, and the self-adjustment of the radar alone can no longer meet the three-dimensional environment around the car. The collection of complete data will increase the blind area of ​​the self-driving car, thereby improving the safety of the car
