Abstract

The invention provides a diesel vehicle NOx emission evaluation method based on the Internet of Vehicles. The diesel vehicle NOx emission evaluation method comprises the following steps: collecting information of a diesel vehicle in real time; evaluating the information emission performance of the diesel vehicle, which is acquired in real time, through an automobile actual operation emission performance evaluation test algorithm; and carrying out weighted summation on the evaluation results in different modes to calculate a comprehensive evaluation result. The method provided by the invention can realize dynamic and real-time online emission performance evaluation of the diesel vehicle, realizes scientific and rapid evaluation of the emission performance of the diesel vehicle in an actual road traffic environment, serves government departments to supervise the emission of the diesel vehicle or make a traffic control decision, and provides a technical support for an enterprise to optimize a diesel vehicle emission control strategy under different regional traffic conditions.

Description

technical field [0001] The invention belongs to the technical field of NOx emission of diesel vehicles, in particular to a method for evaluating NOx emission of diesel vehicles based on Internet of Vehicles. Background technique [0002] The invention relates to an online emission performance evaluation method for diesel vehicles in actual operation based on large data monitored by the Internet of Vehicles, and belongs to the development of an evaluation method for the actual emission performance of diesel vehicles based on the large data monitored by the Internet of Vehicles. [0003] At present, the most serious problem facing our country is the problem of environmental pollution, and the most concerned one is air pollution. Air pollution is closely related to people's daily life, directly or indirectly causing harm to people's health. The main sources of air pollution: fuel combustion, emissions from industrial production processes, emissions from transportation processe...
