Problems solved by technology

When driving with the windows and doors of the car closed, it is difficult to detect the existence of wheel noise and air noise, but you can clearly hear the noise of the parts when they are working (some high-end cars are very sound-proofed) It is also difficult to hear the noise of good parts when they are working), but it is easy to find the existence of wheel noise and air noise when observing other vehicles running on the road, but you cannot hear the noise of parts in the running of the vehicle

Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples, but the following examples should not be construed as limiting the present invention.

[0011] Motor vehicles have many parts, most of which are directly or indirectly related to driving safety. Taking the Elysee sedan produced in Wuhan as an example, the noise characteristics of the Elysee sedan during operation can be divided into five parts, namely "left front Suspension System", "Right Front Suspension System", "Left Rear Suspension System", "Right Rear Suspension System", "Engine, Transmission, Steering System". These five parts are the most important for the safe driving of the car, and 95% of the mechanical failures that endanger the safe running of the car occur in these five aspects. Therefore, five sound sensors are respectively set in each system, and the positions of the sound sensors need to reflect the sound information of each key pa...

Abstract

A method for detecting demand fault of motor vehicle includes setting sound transducer near to key parts of motor vehicle operation, comparing sound detected by said transducer with original sound information stored in noise signal databank by noise signal processing unit for knowing information that detected parts is damaged or not then informing said information to motor vehicle driver through information display unit.

Description

technical field [0001] The invention belongs to a motor vehicle fault detection method and device, in particular to a motor vehicle instant fault detection method and device. Background technique [0002] At present, the vast majority of motor vehicle drivers do not know anything about the repair knowledge of motor vehicle mechanical failures. They only know how to drive, and they will not go to the repair shop until the motor vehicle mechanical failure is serious enough to affect the operation. And often due to the delay of the failure, the damage of the parts is enlarged, and a lot of money is wasted. Especially when a fault occurs during the driving of a motor vehicle, maintenance personnel are required to rescue it in time. However, a set of mechanical equipment for a motor vehicle has a lot of parts, and professional maintenance personnel are required to monitor and determine the location of the fault, but it is impossible for the maintenance pers...
