When the welt rolling is not required, the welt control device 100 of the road roller can be selected to be turned off.

In one embodiment, the luminous color can be automatically adjusted according to the light intensity around the roller 200, such as automatically switching to a green light source under strong light during the day, and selecting a red light source at night or when the light in a tunnel is poor.

In the above embodiment, the method further includes: controlling the operation of the warning device of the road roller 200 based on detecting the obstacle within the preset distance.

When an obstacle is detected within a preset distance, the warning device of the road roller 200 is controlled to operate, so as to warn the driver to control the road roller 200 in time, reduce the probability of collision between the road roller 200 and the obstacle, and thus ensure the safety of the operation.

In any of the above embodiments, the warning device includes but is not limited to a light output device and/or a sound output device, wherein the light output device may be a hazard warning flasher of the road roller 200, and the sound output device may be a horn or the like.
