Method, device and storage medium for determining vehicle test conditions

Abstract

The embodiment of this specification discloses a method, device, and storage medium for determining a vehicle test working condition. The method includes: acquiring vehicle data of a target type vehicle within a preset sampling period, the vehicle data including vehicle speed and vehicle operating condition; based on the vehicle data, Determine the distribution of the vehicle speed range and the distribution of vehicle operating conditions in the operating cycle of the target vehicle test condition; determine the test condition data of the target vehicle test condition based on the vehicle data, the distribution of vehicle speed intervals and the distribution of vehicle conditions; based on the test condition data and Standard working condition data, to determine the final test working condition data of the target type of vehicle. In the above scheme, since the vehicle data of the target type vehicles in the actual operation process are used to determine the final test condition data, the final test condition data can be more in line with the actual operation conditions of the vehicle, and the final test condition data is designed based on the final test condition data. products better meet user expectations.

Description

technical field [0001] The embodiments of this specification relate to the field of automobiles, and in particular to a method, device and storage medium for determining vehicle test conditions. Background technique [0002] In the prior art, the test conditions of automobiles mainly depend on NEDC (New European Driving Cycle), CLTC (China light-duty Vehicle Test Cycle, China light-duty vehicle test cycle), WLTC (Worldwide Light-duty duty Test Cycle, global light vehicle test cycle). [0003] However, the operating characteristics of different models (such as pure electric vehicles and plug-in hybrid electric vehicles) are quite different, and due to factors such as the increase of user groups, road changes, vehicle performance and function iterations, the existing cycle conditions cannot Reflecting the actual vehicle operating status, there is a deviation between the test method used during design and the actual operating conditions, resulting in a large difference between...
