Embodiment 1

[0054] Such as figure 1 As shown, the safe driving method of road roller 14 according to an embodiment of the present invention includes:

[0055] Step S100: the road roller runs at a preset speed;

[0056] Step S102: Continuously detect the distance between the obstacle and the road roller;

[0057] By continuously detecting the distance between the obstacle and the road roller 14, the position of the obstacle can be grasped in real time, so that when the road roller 14 approaches the obstacle, timely measures can be taken to avoid collision.

[0058] Preferably, only the distance between the obstacle in the traveling direction of the road roller and the road roller is detected, so as to avoid complicated structure caused by too many sensors.

[0059] It can be understood that the traveling direction of the road roller is in the length direction of the road roller.

[0060] Step S104: if the distance is greater than or equal to the first preset distance, maintain the prese...

Embodiment 2

[0067] Such as image 3 As shown, the safe driving method of road roller 14 according to an embodiment of the present invention includes:

[0068] Step S200: the road roller runs at a preset speed;

[0069] Step S202: Continuously detect the longitudinal distance and lateral distance between the obstacle in the traveling direction of the road roller and the road roller;

[0070] It can be understood that an obstacle will block the road roller 14 when driving directly ahead, and may block the normal running of the road roller 14 when it is in front of the side, especially when the road roller 14 is turning. The vertical distance in the direction also needs to detect the horizontal distance to accurately judge whether the road roller 14 may hit an obstacle, so that the road roller 14 can avoid it in time.

[0071] It should be pointed out that, as mentioned above, the driving direction of the road roller is in the length direction of the road roller, therefore, the longitudina...

Embodiment 3

[0076] Such as Figure 4 As shown, the safe driving method of road roller 14 according to an embodiment of the present invention includes:

[0077] Step S300: the road roller travels at a preset speed;

[0078] Step S302: Continuously detect the longitudinal distance and lateral distance between the obstacle in the traveling direction of the road roller and the road roller;

[0079] Step S304: the longitudinal distance is less than the first preset distance and greater than or equal to the second preset distance, and the lateral distance is less than the third preset distance, and the road roller is controlled to travel at a first speed less than the preset speed;

[0080] Step S306: Reacquire the distance between the obstacle and the road roller every preset time period;

[0081] In the construction site, the obstacle may be an object, such as piled up materials, or stones on the road surface; it may also be a pedestrian, an animal or a vehicle, and if it is a pedestrian or...

Abstract

The invention provides a safe driving method of a road roller and the road roller. The safe driving method comprises the steps that the road roller runs at a preset speed; the distance between an obstacle and the road roller is continuously detected; if the distance is larger than or equal to a first preset distance, the preset speed of the road roller is kept; if the distance is smaller than thefirst preset distance and is larger than or equal to a second preset distance, the road roller is controlled to run at a first speed smaller than the preset speed; if the distance is smaller than thesecond preset distance, the road roller is controlled to stop running. According to the technical scheme, the distance between the obstacle and the road roller is continuously detected, and measures such as deceleration and stopping are taken along with the reduction of the distance; the obstacle is avoided through an electronic fence, the problem about recognition of concave positions under the ground surface is solved, the active obstacle avoiding capability of the road roller is improved, the occurrence of safety accidents is avoided, and the running safety of the road roller is improved.

Description

technical field [0001] The invention relates to the field of unmanned driving technology, in particular to a method for safely driving a road roller and a road roller. Background technique [0002] In the construction site of the road roller, there are many road rollers, the environment is complex, and the safety is low. When using unmanned driving, there are great safety hazards. Therefore, it is necessary to solve the problem that unmanned road rollers actively avoid obstacles and pedestrians on the construction surface , and the problem of avoiding unsafe areas below the construction surface. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] In view of this, an object of the present invention is to provide a safe driving method for a road roller. [0005] Another object of the present invention is to provide a road roller. [0006] In order to achieve the ab...
