Sensing system of trailer tractor and trailer tractor

Abstract

The invention provides a sensing system of a trailer tractor and the trailer tractor, and relates to the technical field of vehicle control. The sensing system of the trailer tractor comprises a dataprocessing unit and at least one sensor unit; the sensor unit is arranged in a sensor arrangement area; the sensor arrangement area comprises a first sensor arrangement area located at the front partof the trailer tractor, second sensor arrangement areas located at the two sides of the trailer tractor, and a third sensor arrangement area located at the rear part of the trailer tractor; and the sensor units include a first sensor unit disposed in the first sensor arrangement area, a second sensor unit disposed in the second sensor arrangement area, and a third sensor unit disposed in the thirdsensor arrangement area. According to the sensing system of the trailer tractor and the trailer tractor, the environment areas in front of, on the side of and behind the trailer tractor can be sensed, so that sensing blind areas of the trailer tractor are effectively reduced, and the driving safety of the trailer tractor is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a perception system of a tractor with a trailer and the tractor with a trailer. Background technique [0002] Autonomous driving and assisted driving have been the focus of attention in the automotive field in recent years, and autonomous driving commercial vehicles have attracted much attention because they are considered to be the segment that can be implemented the fastest. [0003] Different from passenger cars, commercial vehicles have great difficulty in sensing the environment around the body in the research of automatic and assisted driving due to their special body structure. Especially for the main model of high-speed logistics - trailer tractor, due to its long body length and the folding angle between the tractor and trailer when turning, the environment sensing on the side and directly behind the trailer is relatively weak when driving straight. It is diffic...

AI Technical Summary

Problems solved by technology

Especially for the main model of high-speed logistics - trailer tractor, due to its long body length and the folding angle between the tractor and trailer when turning, the environment sensing on the side and directly behind the trailer is relatively weak when driving straight. In addition, when turning and parking, there will be a large area of ​​sensing blind spots in the above two areas, which will seriously affect the driving safety of the trailer.
