Problems solved by technology
[0004] Usually, autonomous driving tractors are required to be able to complete actions such as trailer towing, road driving, and obstacle avoidance recognition without the driver's intervention. Blind spots, so the requirements for the perception system of the vehicle are higher
The sensors used in the existing technology generally have shortcomings such as large detection blind spots, poor detection distances and poor accuracy.

Embodiment Construction
[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.
[0031] At present, the demand for long-distance transportation is increasing day by day. Using self-driving tractors for transportation can significantly improve the driving safety of drivers and can also greatly reduce logistics costs. However, due to the larger size of the tractor, it is easy to produce blind spots in scenarios such as turning, so the requirements for the perception system of ...

The invention provides a sensing system of an automatic driving tractor and the automatic driving tractor, and relates to the technical field of automatic driving. The sensing system of the automaticdriving tractor comprises a computing unit, a sensor system and a fixing mechanism for fixing the sensor system; the sensor system comprises a millimeter wave radar module, a laser radar module and acamera module. the millimeter-wave radar module comprises a short-distance millimeter-wave radar and a medium-distance millimeter-wave radar; the camera module comprises a front-view camera, a wide-angle camera and a middle-distance camera; and the laser radar module comprises at least one laser radar. By means of the sensing system of the automatic driving tractor and the automatic driving tractor, dead-corner-free sensing can be achieved within the range of 360 degrees around the automatic driving tractor, a better sensing effect is achieved, automatic towing of the automatic driving tractorcan be achieved, and therefore the sensing requirement for the sensor system is met.
Description
technical field [0001] The invention relates to the technical field of automatic driving, in particular to a perception system of an automatic driving tractor and the automatic driving tractor. Background technique [0002] Self-driving vehicles mainly use on-board sensors to perceive the surrounding environment of the vehicle and vehicle information, and after analysis and processing by the on-board computing unit, information such as road conditions, vehicle position and obstacles are obtained, and then intelligently and autonomously control the steering, speed and braking of the vehicle system, so that the vehicle can run safely and reliably on the road. [0003] A tractor is a vehicle used to tow a trailer carrying cargo, and is generally used in medium and long-distance cargo transportation. At present, the demand for long-distance transportation is increasing day by day. The use of self-driving tractor vehicles for transportation can significantly improve the driving ...
