Description

Technical Field

[0001] The present invention relates to the technical field of automobile detection and maintenance, and in particular to an integrated platform for automobile fault setting and diagnosis and a method for using the platform. Background Art

[0002] As automobile technology continues to innovate, the demand for professional talents in the automobile inspection and maintenance industry is growing, and the requirements for their skill levels are becoming more and more stringent. The traditional teaching methods of automobile fault diagnosis and maintenance have many limitations and cannot meet the development needs of the modern automobile maintenance industry.

[0003] On the one hand, previous teaching equipment cannot fully and realistically simulate the various types of faults that may occur in the actual use of the car, resulting in insufficient understanding and handling ability of students during the learning process, and it is difficult for them to quickly and accurately diagnose and repair faulty vehicles after entering the workplace. For example, some teaching equipment can only set simple circuit faults, and cannot simulate complex electronic control system faults, leaving students helpless when faced with complex faults in actual vehicles.

[0004] On the other hand, the existing fault diagnosis learning resources are relatively scattered. Students need to consult a variety of materials during the learning process, which consumes a lot of time and energy, and the accuracy and timeliness of the materials are difficult to guarantee. For example, maintenance manuals, circuit diagrams and other materials may be outdated and have incomplete information, which to a certain extent affects the learning effect and improvement of students' fault diagnosis capabilities. At the same time, due to the lack of an integrated learning platform, it is difficult for students to effectively combine theoretical knowledge with practical operations, and they cannot conduct comprehensive learning and practice in a systematic environment.

[0005] In addition, with the popularity of new energy vehicles, the electronic control systems of vehicles have become more complex, and traditional teaching methods and equipment can no longer meet the needs of training talents for new energy vehicle fault diagnosis and maintenance. Key technologies such as the battery management system and motor control system of new energy vehicles are very different from those of traditional fuel vehicles, and require special teaching equipment and methods for teaching. However, the current teaching resources and equipment for new energy vehicle fault diagnosis and maintenance in the market are relatively scarce, making it difficult to meet teaching needs. Summary of the invention

[0006] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide an integrated platform for automobile fault setting and diagnosis and a method of using the same, which can solve the problem that previous teaching equipment cannot comprehensively and realistically simulate various types of faults that may occur in the actual use of a car, resulting in insufficient students' ability to recognize and handle faults during the learning process.

[0014] S2 circuit breaker fault setting: Simply unplug the U-shaped plug to set the circuit breaker fault; for example, if you want to set the circuit breaker fault of a certain line in the engine control system, find the U-shaped plug of the corresponding pin and unplug it;

[0015] S3 short-circuit fault setting: Use 2mm butt wire to connect two terminals that need to be short-circuited together to form a short-circuit fault; however, before operation, be sure to consult relevant information to confirm that this terminal meets the short-circuit setting requirements, otherwise the module unit may be burned; if a specific signal terminal in the vehicle control system is short-circuited, its safety must be confirmed in advance;

[0016] S4 virtual connection fault setting: After unplugging the U-shaped plug, insert a resistor in series to achieve the virtual connection fault setting; assuming that the virtual connection fault is set in the battery pack management system, you can operate according to this method;

[0017] S5 short-circuit to ground fault setting: Use a 2mm butt wire to connect one end to the negative pole and the other end to the system pin to complete the short-circuit to ground fault setting;

[0022] S10 Analysis and troubleshooting: Based on the actual vehicle fault phenomenon, the data read by the fault diagnosis instrument, and the signal data obtained by the measuring instrument, in-depth analysis is carried out to gradually troubleshoot and determine the fault location. If the fault diagnosis instrument shows that a certain engine sensor is faulty and the voltage signal of the sensor is abnormal, combined with the actual vehicle phenomenon, it can be determined that there is a problem with the sensor or its circuit;

[0023] S11 Enter the query system: Open the BYD Qin PLUS vehicle fault diagnosis query system, which is integrated in the control host of the vehicle fault setting and detection console and is presented through the teaching display;

[0024] S12 Select the data type: In the system navigation menu, you can choose to switch between different types of technical data such as maintenance manuals, circuit diagrams, training work orders and equipment instructions. When troubleshooting vehicle electrical faults, you can select the circuit diagram to view the connection and layout of related lines;

This rich and diverse fault setting enables students to be exposed to various actual possible fault conditions and have an in-depth understanding of the impact of different faults on vehicle systems, thereby effectively improving students' fault diagnosis and maintenance practical ability. Taking the engine control system as an example, students can set different types of faults, observe the changes in the engine's operating status, and learn how to accurately determine the fault type and location based on the fault phenomenon and measurement data.

[0028] 2. The integrated platform for automobile fault setting and diagnosis and its use method.
