OBD-based vehicle quality dynamic measuring device and measuring method

Abstract

The invention discloses an OBD-based vehicle quality dynamic measuring device and an OBD-based vehicle quality dynamic measuring method. The OBD-based vehicle quality dynamic measuring device comprises an OBD interface and an embedded measuring device body. An OBD can output driving data such as engine torque, vehicle position, vehicle speed and vehicle acceleration in real time; the embedded measuring device body is used for processing and analyzing data acquired from the OBD interface. The real-time, rapid and accurate measurement of vehicle quality is completed during the vehicle driving process by adopting the OBD-based vehicle quality dynamic measuring method disclosed by the invention. The OBD-based vehicle quality dynamic measuring method and device overcome the defects of low efficiency, low speed and poor precision of the traditional vehicle quality measuring method, are suitable for real-time measurement of vehicle quality, can perform effective monitoring on situations such as vehicle overload, hazardous article leakage in the transportation process and loss of goods, and play good supporting roles in standardizing traffic safety management, improving logistics transportation safety and guaranteeing economic benefit.

Description

technical field [0001] The invention relates to an OBD-based vehicle quality dynamic measurement device and a measurement method, belonging to the technical field of vehicle dynamic weighing. Background technique [0002] In recent years, my country's logistics industry has continued to develop and improve, but with it, the phenomenon of vehicle overloading continues to increase. The freight department greatly improves the carrying capacity of the vehicle by transforming the body, rear axle and tires, which improves the transportation efficiency and economic benefits, but overloading will bring a series of hazards: accelerated damage to the road surface and increased road maintenance costs; Road maintenance fees and management fees are collected according to the tonnage of the vehicle. Overloading will cause a large loss of national tax revenue; when overloading, the engine will run overloaded and the exhaust gas and noise will increase significantly, causing serious environ...

Problems solved by technology

[0006] There are two traditional vehicle quality measurement methods, one is the static weighing method, which requires the vehicle to stop completely on the scale body for measurement, this detection method is more accurate, but the efficiency is low, the speed is slow, and it does not have a good application value; the other is the dynamic weighing method, which can measure the mass of the vehicle under normal driving conditions, but this method requires a large scale body with a vehicle load cell, which is inconvenient to use and has low accuracy
