Beschreibung
Zusammenfassung:	The invention provides a vehicle DPF performance test method and device, and the method comprises the steps: placing a test vehicle in a preset test environment, debugging the test vehicle to a preset state, and collecting and storing the pre-test vehicle data of the test vehicle before the test; according to a preset test method, driving the test vehicle to carry out a DPF performance test; after-test vehicle data of the test vehicle after each test are collected and stored, an experiment report is obtained according to the before-test vehicle data and the after-test vehicle data, and a performance result of the DPF of the test vehicle is determined according to the experiment report; wherein the preset test method at least comprises a DPF regeneration mileage test scheme and a DPF regeneration efficiency test scheme. The method solves the problem that in the prior art, a method for testing the unfavorable regeneration working condition of the DPF is lacked. 本发明提供一种车辆DPF性能测试方法及装置，所述方法包括：将测试车置于预设的测试环境中，并将所述测试
