Abstract

The invention discloses vehicle-mounted equipment and a road maintenance assistant management system. The vehicle-mounted equipment is connected to a vehicle bus and obtains the following information:vehicle speed, acceleration and position, wherein all or part of the information is from the vehicle bus; on the basis of the obtained information, the vehicle-mounted device detects whether a vehicle encounters a road damage on a road on which the vehicle is traveling, including: if instantaneous deceleration of the vehicle in the traveling direction are continuously detected and each instantaneous deceleration value is greater than a first threshold value, if the difference value between the instantaneous acceleration of the vehicle perpendicular to the ground and each adjacent instantaneous acceleration value is continuously detected to be greater than a second threshold value, and if the continuously detected real-time speed does not tend to zero after the instantaneous deceleration and the instantaneous acceleration are continuously detected, the vehicle-mounted device generates a road damage report including positions detected within the time interval in which the instantaneousdeceleration and the instantaneous acceleration. The vehicle-mounted equipment provided by the invention can improve the efficiency of road maintenance management without increasing additional hardware cost.

Description

technical field

[0001] The invention relates to the Internet of Vehicles technology, in particular to a vehicle-mounted device and a road maintenance auxiliary management system. Background technique

[0002] At present, most of the city's road maintenance still relies on the road maintenance department to conduct follow-up repair operations after manual inspections find road damage, or rely on sensor equipment installed on fixed road sections to perform follow-up repair operations after discovering road damage. Recently, some road maintenance departments have also set up a background service for road maintenance. The background provides road damage reporting telephones to the public, and coordinates repair operations by receiving telephone reports from public vehicles traveling on a certain road section about road damage in this section.

[0003] Although the method of detecting and reporting road damage by public vehicles expands the detection area of ​​road damage, it als...
