Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] The purpose of the present invention is to provide a method and system for remote noise monitoring and diagnosis of automobiles, which can remotely monitor the real-time noise and vehicle running status of the vehicle, and diagnose vehicle faults according to the monitoring data.

[0017] In order to achieve the above purpose, as figure 1 As shown, the automobile remote noise monitoring and diagnosis system provided by the present invention includes a controller, and the controller can be a separate controller or an original on-board controller on the car. The controller is connected to the vehicle motion state detection unit and The interior noise detection unit and the controller realize data transmission with the remote terminal through wireless communication.

[0018] A fault standard library is stored in the remote terminal. At least two standard...

Abstract

The invention relates to the field of remote monitoring of automobiles, and in particular relates to a remote noise monitoring and diagnosing method and system of an automobile. Noise data in the automobile and running state data of the automobile are acquired in an automobile running process; and the acquired data is sent to a remote terminal and compared with a stored fault standard library, sothat the fault condition of the automobile is judged. According to the remote noise monitoring and diagnosing method and system of the automobile in the invention, the problem that remote fault detection is not comprehensive and inaccurate in the automobile running state can be solved; the change condition of the acoustic state in the automobile is known; and, in combination with the automobile running state, the fault condition of the automobile is effectively judged according to the fault standard library.

Description

technical field [0001] The invention relates to the field of remote monitoring of automobiles, in particular to a method and system for remote noise monitoring and diagnosis of automobiles. Background technique [0002] Automobile NVH (noise, vibration and harshness) performance has become one of the important performance indicators for drivers and occupants to choose automobile products, and it has also become an important manifestation of the technical strength of automobile manufacturers. Therefore, engineering designers focus their energy on the vehicle development process, but they often ignore the NVH performance deterioration of the vehicle caused by component damage and performance cracking after high-mileage work. The existing technology only considers the remote monitoring of the working state of the vehicle, but does not consider the monitoring of the NVH performance in the vehicle, which is one of the performances of the whole vehicle, resulting in an insufficien...
