Embodiment 1

[0042] Such as Figure 1~3 The shown unmanned cleaning vehicle includes a car body 1, and a driving system, a steering system, a road recognition system, an anti-collision system, a brake-by-wire system, a main controller 2 and a cleaning system arranged on the car body 1 . The traveling system is used to execute vehicle traveling, and the traveling system includes a straight-running motor 31 and straight-running wheels 32 , and the straight-running wheels 32 are driven by the straight-running motor 31 . The steering system includes a steering motor 41 and a steering wheel 42 connected to the output end of the steering motor 41 . Wherein, the straight wheel 32 is a rear wheel, and the steering wheel 42 is a front wheel. The road recognition system includes a high-definition camera 51 and an industrial computer 52. The high-definition camera 51 is used to collect images of the road ahead of the vehicle, and the industrial computer 52 is used to process image information, ident...

Embodiment 2

[0050] This embodiment is based on the structure of the unmanned sweeper in embodiment 1, and a driving method of the unmanned sweeper provided includes the following steps:

[0051] Step 1: The system presets the driving route, including the starting point, end point and driving trajectory, the driving speed and time of the straight road section in the driving trajectory, the turning direction, the total turning angle and the number of turns in the curved road section.

[0052] Step 2: The vehicle drives according to the system's preset driving path; during the driving process, the vehicle's road recognition system collects images of the road surface in front of the vehicle through a high-definition camera, identifies the road ahead and plans the driving direction; the vehicle's anti-collision system identifies the distance between the vehicle and the curb signal, adjust the distance between the vehicle and the curb in real time or apply the brakes in time.

Abstract

The invention relates to the field of sanitation vehicles. An unmanned sweeper includes a driving system for executing vehicle driving instructions; a steering system for executing vehicle steering instructions; a brake-by-wire system for executing vehicle braking instructions; a road recognition system for collecting road surfaces in front of the vehicle The image is processed to identify the road conditions in front of the vehicle, plan the driving direction and issue driving instructions; the anti-collision system detects the distance between the vehicle and the curb in real time; the main controller (ECU) receives the driving instructions from the road recognition system, and the main controller (ECU) ) to control the driving system, steering system and brake-by-wire system to plan the driving direction; the main controller (ECU) receives the distance signal between the vehicle and the curb fed back by the anti-collision system, and the main controller (ECU) controls the driving system and the curb based on the above distance signal. The steering system adjusts the distance between the vehicle and the curb. As long as the unmanned cleaning vehicle sets the path for cleaning the community, the unmanned vehicle can complete the workload of multiple sanitation workers.

Description

technical field [0001] The invention relates to the field of sanitation vehicles, in particular to an unmanned cleaning vehicle and a driving method thereof. Background technique [0002] The traditional sanitation mode is basically the following two: 1. Our sanitation workers manually clean the garbage in the community or street; 2. Manually drive the sanitation cleaning vehicle to clean the garbage in the community or street. Because the sanitation system relies heavily on manpower, and the lack of former sanitation workers directly leads to the overload of cleaning work for each of the existing sanitation workers every day, and at the same time, because sanitation workers often work on the side of the road, it puts the life safety of sanitation workers at risk. Therefore, in order to reduce the cost of sanitation operation and maintenance, to reduce the work pressure of sanitation workers, and to protect the life safety of sanitation workers, from a long-term perspective,...
