Problems solved by technology
[0003] As for the mechanical failure of the vehicle, such as cracking, wear, deformation, loosening, etc., it is often discovered after the failure occurs, and usually the loss caused by the mechanical failure is relatively large
At present, the inspection of mechanical faults is carried out by manual visual inspection or by tapping on mechanical parts to listen to the sound, which has a lot to do with the experience of the operator, and the limitations are relatively large, and it is not easy to find potential problems

Embodiment Construction
[0027] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0028] figure 1 It is a flow chart of a method for detecting vehicle mechanical faults provided by an exemplary embodiment. applied to the vehicle. Such as figure 1 As shown, the method may include the following steps.
[0029] In step S11, the sound emitted by the component under test in the vehicle during operation is acquired.
[0030] In step S12, a mechanical fault of the tested component is determined according to the acquired voiceprint feature.
[0031] Wherein, one or more microphones may be respectively arranged at one or more positions around the component under test. These microphones are used to capture the sound of the components under tes...

The invention relates to a method and device used for detecting a mechanical breakdown of a vehicle. The method used for detecting the mechanical breakdown of the vehicle comprises the steps that sound emitted by a detected part of the vehicle during running is obtained; and the mechanical breakdown of the detected part is determined according to voiceprint characteristics of the obtained sound. Due to the fact that the same mechanical breakdown has similar voiceprint characteristics, therefore, detecting is conducted by utilizing the physical characteristic of the voice characteristics of themechanical breakdown, thus fault detection and missing detection caused by the lack of experience of detecting personnel is avoided, so that detecting of the mechanical breakdown of the vehicle is more timely and accurate, and vehicle running is more safe.
Description
technical field [0001] The present disclosure relates to the field of vehicle equipment, and in particular, to a method and device for detecting vehicle mechanical faults. Background technique [0002] Vehicles are consumables, and generally their performance will gradually degrade as the vehicle ages. The regular maintenance of the vehicle is to discover and eliminate hidden dangers in time, prevent the occurrence of breakdowns, and effectively extend the service life of the vehicle. [0003] As for the mechanical failure of the vehicle, such as cracking, wear, deformation, loosening, etc., it is often discovered after the failure occurs, and usually the loss caused by the mechanical failure is relatively large. At present, the inspection of mechanical failures is carried out by manual visual inspection or by tapping mechanical parts to listen to the sound. This has a lot to do with the experience of the operator, and the limitations are relatively large, and it is not eas...
