Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046]In the prior art, a processing method, processing system, and vehicle for motor system efficiency MAP data are disclosed, although the prior art can "provide a drive motor efficiency MAP map, and select a target area on the efficiency MAP map, ...get the statistical results of the efficiency of the motor system in the target area", but it does not involve the processing of powertrain efficiency data and current data other than the motor during the efficiency test (powertrain: including "motor (with gearbox) + Electric control")). During the powertrain test process, the original test data is easily interfered by factors such as on-site electromagnetic interference, equipment accuracy and response speed, operator proficiency, and cannot be a...

Abstract

The invention provides an efficiency test data processing method for a driving motor system, and the method comprises the steps of reading original efficiency test data of the driving motor system, forming a seven-column number table, carrying out the missed recording error correction and repeated data error correction processing of all data in the seven-column number table, and obtaining error-corrected non-abnormal data; reading rotating speed data, torque data and shaft power data in the non-abnormal data, and obtaining external characteristic data through data screening so as to draw an external characteristic curve of the driving motor; reading data without abnormity, screening key information, drawing and outputting a driving motor efficiency MAP, a driving motor controller efficiency MAP, a driving motor system efficiency MAP, a driving motor current MAP and a driving motor rotating speed-torque-efficiency three-dimensional diagram, and adding annotations aiming at the key information on the drawn diagrams. According to the invention, automatic error correction of original data is realized; external characteristic data screening and automatic result output functions of the tested power assembly are realized; and simultaneous output of multiple types of test results is realized.

Description

technical field [0001] The invention relates to the field of electric vehicle testing, in particular to a method and device for processing efficiency test data of a drive motor system. Background technique [0002] At present, based on the increasingly serious environmental and energy problems, the extensive research and development, promotion and application of electric vehicles in the industry have been promoted. However, the cruising range of electric vehicles is still a technical difficulty. [0003] As the core component of the electric vehicle, the drive motor system converts the electric energy of the battery into mechanical energy to drive the vehicle, and its working efficiency directly affects the battery life of the electric vehicle. In practical applications, the use of the drive motor system is very complicated in response to different working conditions (low-speed climbing, high-speed climbing, emergency acceleration, emergency braking). In the prior art, ther...
