Abstract

The present invention provides a road gradient measurement method and device based on the power distribution of large-scale networked vehicles, wherein the method includes: acquiring vehicle operation data of the vehicle on the current road section and vehicle operation data corresponding to the vehicle's historical driving section, the vehicle operation data including the engine Data, vehicle speed, acceleration, and vehicle load; determine the slope data of the current road section according to the vehicle operation data of the vehicle on the current road section and the corresponding vehicle operation data of the vehicle on the historical road section. By implementing the present invention, the slope calculation is not restricted by region, and has universal applicability, and the calculation amount is small compared with the method of calculating the slope through sensor data, and at the same time, the influence of the vehicle load on the calculation of the slope data is taken into account, and the road slope calculation is improved. accuracy and efficiency. Moreover, this embodiment can only rely on the vehicle operation data collected by the remote online monitoring platform, without adding additional sensor equipment, and has high implementability.

Description

technical field [0001] The invention relates to the field of slope measurement, in particular to a road slope measurement method and device based on power distribution of large-scale networked vehicles. Background technique [0002] Road transportation has always been an important part of my country's cargo transportation. As a vehicle for road transportation, heavy-duty trucks undertake heavy cargo transportation tasks. The increase in the number of motor vehicles in my country, especially the number of trucks, has put forward higher demands on highway overload control, vehicle operation safety monitoring, vehicle emissions and energy consumption. Among them, the impact of the road slope on the above-mentioned aspects of the vehicle is particularly significant. Accurate road slope data can significantly improve the accuracy of vehicle dynamic load calculation results, can calculate more accurate safety limit speed, and can also output more comfortable and economical data. ...
