System and method for detecting energy consumption and emission of hybrid electric vehicle

Abstract

The invention discloses a system for detecting the energy consumption and the emission of a hybrid electric vehicle. The system comprises a vehicular energy consumption and emission measuring device connected with a computer system, wherein the computer system comprises a data acquisition module and a detection and comparison model; the data acquisition module is used for acquiring and receiving the data of the vehicular energy consumption and emission measuring device, and the acquired data comprises fuel oil consumption, electric energy consumption and the mass emission of HC, CO, NOx and particulate matters (PM); the detection and comparison model comprises a plurality of databases, and at least the following information is stored in the databases: (A) energy consumption and emission data obtained in a field test of a testing field by a conventional diesel-engine vehicle, (B) energy consumption and emission data obtained in an analog line test by the conventional diesel-engine vehicle and (C) energy consumption and emission data obtained in a practical line operation by the conventional diesel-engine vehicle; and the acquired data is compared with the detection and comparison model by a data analyzing module to analyze the energy consumption and emission properties of hybrid electric vehicles of the same technological types or different technological types.

Description

technical field [0001] The invention relates to a vehicle energy consumption emission detection system and detection method, in particular to a hybrid electric vehicle energy consumption emission detection system and detection method. Background technique [0002] At present, governments around the world are vigorously advocating the development of clean energy, adjusting industrial structure, carrying out ecological construction, preventing ground dust and controlling motor vehicle pollution, which has improved the quality of the atmospheric environment to a certain extent. Among the prevention and control measures adopted, motor vehicle pollution control measures accounted for about one-third. [0003] With the continuous maturity of heavy-duty hybrid vehicle technology, more optional directions are provided for the development of low-emission buses, and hybrid buses have greater potential advantages in terms of energy saving and emission reduction. Many successful attemp...
