Problems solved by technology

However, in practice, the fault that the output data of the speed sensor is not true often occurs
Specifically, the rotational speed sensor can output the collected rotational speed signal smoothly, but the output rotational speed signal is quite different from the actual rotational speed of the rotating part collected.

Abstract

The invention relates to a fault determination method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring rotating speed data acquired by at least three rotating speed sensors associated with a gearbox; performing pairwise calculation on the rotating speed data acquired by each rotating speed sensor to obtain a calculation result; and on the basis of each calculation result and a standard value corresponding to each calculation result, determining whether each gearbox rotating speed sensor has a fault or not. By adopting the technical scheme provided by the embodiment of the invention, whether the rotating speed sensor has a fault of unreal output data can be identified.

Description

technical field [0001] The present disclosure relates to the technical field of gearboxes, and in particular to a fault determination method, device, electronic equipment and storage medium. Background technique [0002] The gear ratio of the gearbox is equal to the input shaft speed divided by the output shaft speed. In order to better control the gearbox, the TCU (Transmission Control Unit, gearbox controller) needs to obtain the input shaft speed and output shaft speed in real time. However, in practice, the fault that the output data of the speed sensor is not true often occurs. Specifically, the rotational speed sensor can output the collected rotational speed signal smoothly, but the output rotational speed signal is quite different from the actual rotational speed of the rotating member collected. How to determine whether there is such a fault in the speed sensor is an urgent problem to be solved at present. Contents of the invention [0003] In order to solve th...
