Abstract

The embodiments of the invention disclose a torque model-based data processing method and device, a rack and a storage medium. The method comprises the steps that the measurement data of a test enginein at least one steady-state working condition is acquired in a rack test; and according to a preset torque model, the calculation torque output by the torque model under each steady-state working condition is determined, an information association table of the torque of a test vehicle and the corresponding working conditions is determined according to the calculated torque and the actual torquein combination with a preset rule, so that the running parameters of the engine of the test vehicle under the current demand torque are determined according to the information association table duringactual driving of the test vehicle. Compared with the prior art, the measurement data of the test engine under different steady-state working conditions are utilized in the embodiments of the invention, and then the torque model is combined to obtain the information association table of the torque and the working conditions, thereby providing a basis for the form of a vehicle for subsequently installing the test engine, and meeting the driving demand; and in addition, manual execution is not needed in the process, the automatic processing of the data is realized, and the processing time is shortened.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a torque model-based data processing method, device, platform and storage medium. Background technique [0002] During the engine development process, it is usually necessary to calibrate the engine on a bench to meet the development requirements of the engine performance and the development requirements of the whole vehicle. Engine bench calibration includes torque model calibration, ignition angle calibration and temperature model calibration. [0003] Taking torque model calibration as an example, the purpose of torque model calibration is to make the torque calculated by the torque model as close as possible to the actual output torque of the engine, so that the power output characteristics of the engine can meet the driving needs. During the calibration process, it is necessary to adjust the ignition angle and torque according to differ...
