Active control device for lidar

Abstract

The invention discloses an active control device of a laser radar. The active control device comprises a servo motor, a speed reducer, an upper bearing, a tapered roller bearing, a rotating shaft, a radar fixing base, a support frame, an upper bearing pedestal, a lower bearing pedestal and a control system, wherein the support frame is fixed at the front part of a vehicle body; the servo motor, the speed reducer, the upper bearing and the tapered roller bearing are arranged on the support frame; an output shaft of the servo motor is connected with an input shaft of the speed reducer; an output shaft of the speed reducer is connected with the rotating shaft; the upper end and the lower end of the rotating shaft are respectively arranged in the upper bearing and the tapered roller bearing in a penetrating way; the upper bearing and the tapered roller bearing are respectively arranged in the upper bearing pedestal and the lower bearing pedestal of the support frame; the radar fixing base is fixed on the rotating shaft and can rotate along with the rotating shaft; the control system is connected with the servo motor and controls the servo motor to work. The laser radar is fixed on the radar fixing base and can rotate along with an automobile steering lamp, so as to cover a blind area to a maximum degree. The safety of vehicle driving is improved, and the safety of turning driving at an intersection is particularly improved.

Description

Technical field [0001] The invention relates to a device for improving driving safety, in particular to a device for active control of laser radar, and belongs to the field of automobile safety. Background technique [0002] With the continuous development of the automobile industry and the continuous improvement of people's living standards, automobiles have become a means of transportation for everyone. However, the continuous increase in the number of cars has also led to frequent traffic accidents. Among all the road traffic sections, it can be said that the situation of intersections is the most complicated, especially the intersections in cities, where all kinds of vehicles gather and the density of pedestrians is high. It is a frequent place for traffic accidents. Therefore, traffic safety at intersections should be a cause for all of us. High attention. Although traditional automotive radar systems continue to develop with the advancement of science and technology, they...

AI Technical Summary

Problems solved by technology

Although the traditional automotive radar system continues to develop with the advancement of science and technology, it can reduce or avoid casualties and property losses as much as possible, but there are still many problems in the traditional fixed automotive radar system, such as the limited detection angle and the inability to realize blind spot detection. maximum coverage

In the face of complex road conditions, especially when the car is driving at an intersection, the driver cannot take into account the road conditions in all directions, and there is a huge potential safety hazard
