Vehicle fault diagnosis equipment

Abstract

The invention relates to a vehicle fault diagnosis device, which comprises a connector part that inputs the sensor data and fault code data of a vehicle from the OBD-II connector of the vehicle through a data cable; a microprocessor that comprises a control part and a memory part and calculates and processes data input by the connector part; a displayer part and an audio output part that output the data calculated and processed by the microprocessor in a pictorial and audio way; a first serial port that is connected with a wireless communication module so as to transmit the data output from the microprocessor and to receive external data; and a second serial port that is connected with an external device so as to transmit the data output from the microprocessor and to receive external data; an external memory slot used for storing the data output from the microprocessor into an external memory. According to the structure, abnormal situation of the vehicle in an initial stage can be found, thus preventing the fault expansion of other parts, reducing maintenance cost, and guarding in advance against risk factors brought to the running of the vehicle and driver.

Description

technical field [0001] The present invention relates to a kind of vehicle fault diagnosis equipment (Fault Diagnosis Apparatus for Vehicle), relate in particular to obtain the sensor data and fault code of vehicle from the OBD-II (On-Board Diagnosis-II, the second generation on-board diagnostic system) connector of vehicle It is a vehicle fault diagnosis equipment that outputs the current state of the vehicle or the fault location in real time with screen and sound. Background technique [0002] At present, from the perspective of changes in the automotive environment, the biggest changes include the rapid digitization of vehicles, the integration of multimedia products into automotive components, and the accompanying improvement in vehicle performance and the provision of various contents. Typical examples are small computers and multimedia devices such as MP3 players that control engines, transmissions, ABS (anti-lock braking systems), and air bags. With the development o...

Problems solved by technology

[0007] These existing vehicle fault diagnosis devices cannot detect the fault code until they take the vehicle to a repair shop to read the fault code in order to know whether there is any abnormality in the vehicle, so there is a problem that it cannot take a quick response.

In addition, there is a problem that it is difficult to prevent safety accidents in advance because prompt measures cannot be taken against various abnormalities that occur during operation.
