Description

[0001] FAULT DETECTION AND REPAIR TEST SYSTEM THAT CAN PERFORM AI-DRIVEN LEARNING AND FUNCTIONAL TESTING

[0002] Technical Field

[0003] The invention relates to a system configured to identify the source of faults in vehicles, both heavy and other types of vehicles, by performing functional analyses on units that are or may be the cause of the faults, either on the vehicle or independently of it, using artificial intelligence to learn and identify the source of faults or potential sources of partial faults without relying on a specific algorithm, and is also capable of determining the extent to which partial faults may become significant issues in the future.

[0004] State of the Art

[0005] Technological advancements in the heavy vehicle sector are bringing more complex structures. The changes brought about by these innovations require different remedies due to the lack of adequate training and the extended time needed for specialization.

[0006] Due to the large number of mechanical, electromechanical, sensors and actuators in heavy vehicles and the need for specialisation in each of them, the services prefer to replace them with new ones for every fault they cannot resolve. This increases costs and causes the world's resources to be wasted even for faults that can be easily fixed. The number of specialised mechanics trained in heavy vehicle services is gradually decreasing, leading to a shortage of specialised mechanics.

[0007] Existing fault detection devices can solve limited problems with standard algorithmic methods. In order to translate many faults or problems into an identifiable algorithm, it is necessary for the personnel in repair services to identify the sources of faults and report them to the company that develops the diagnostic device, and for them to use the content of this report to develop software and hardware. However, most repair services do not have such a competence and do not provide feedback in order to develop remedies.

[0008] Today, limited remedies can be provided by the fault detection devices used today and the desired level of test results cannot be obtained as a result of the repair process. Complex component structures can produce limited remedies due to limited algorithms and do not show unknown fault sources at all.

[0009] In the diagnostic methods used in current applications, subsequent faults after the first fault found in the tested unit cannot be detected, the service operator repeats the test process after eliminating the fault reported to be faulty and continues until all faults are eliminated. However, the available data is sufficient to find more fault sources.

[0010] In the diagnostic methods used in the state of the art, when the information received from the sensors in the tested unit is also inaccurate, it continues to show the fault in the sensor, even if the fault source is in other mechanical components.

[0011] As a result, the existence of the above problems and the inadequacy of existing remedies necessitated a development in the relevant technical field.

[0012] Object of the Invention

[0013] The present invention relates to a fault detection and repair test system which eliminates the above-mentioned disadvantages and brings new advantages to the relevant technical field. The main object of the invention is to provide a system that detects faults in both heavy vehicles and all vehicles by means of artificial intelligence, finds the source of the fault and makes repair suggestions, and can learn different fault sources by means of artificial intelligence.

[0014] The object of the invention is to provide a system that uses structured artificial intelligence to perform comprehensive tests on integrated construction in heavy vehicles, such as sensors, electromechanical valves, EBS, ABS, ESR, ASR, and TC, which have communication features and contain sensors and actuators, by conducting functional tests through learned artificial intelligence that controls these sensors and actuators without needing to know the operational logic of the unit, and to offer fault diagnosis and repair recommendations based on the findings obtained.

[0015] Another object of the invention is to provide a system that provides the integrity of the air pressure, the necessary electrical signals, the necessary supply voltages and currents, the necessary communication commands and data with the pneumatic, electronic compartments and software components within its structure, according to the needs of the unit under test, while performing the specified functional and holistic tests.

[0016] Another object of the invention is to provide a system that shortens the diagnosis and repair time by controlling the sensors and actuators in heavy vehicles, diagnosing the fault in the tested unit, sharing the repair suggestions with other system users in other repair services, and providing training of other service personnel in a short time.

[0017] Another object of the invention is to use the measurements and information on the tested unit in the training of artificial intelligence, and then to provide a system configured to enable the detection and repair of unpredictable fault sources. Another object of the invention is to present a system that is configured in such a way that it can be used in the training of artificial intelligence by collecting the new remedies that will be formed with the diagnosis and repair suggestions of each fault source on a server, and enabling the mechanics in the repair services to get different remedies by asking questions to the artificial intelligence on this server.

[0018] Another object of the invention is to provide a system that makes the vehicle repair service profession more easily applicable by providing services such as training and guiding assistants in order to ensure that the new personnel in the repair services are mastered in a short time.

[0019] Another object of the invention is to present a system that can detect the fault sources that cannot be solved by standard algorithmic methods through artificial intelligence, list the circumstances that may be the source of the fault, and provide the necessary communication, software, software configurations, electronic signals and pneumatic requirements for functionality and tests at the desired values with its components.

[0020] Another object of the invention is to provide a system that can provide all functions such as variable air pressures, variable signals, variable voltages, continuous communication with the unit, which are required during the operation of the tested unit on the vehicle, sequentially or automatically, so that the service operator can test it without the need for manual intervention.

[0021] Another object of the invention is to provide a system that can process the faults and diagnoses learnt by artificial intelligence on a server so that they can be used by other services.

[0022] Another object of the invention is to provide a system with an artificial intelligence feature that can produce results for other mechanical fault sources and detect possible new faults according to the analysis of the data received from the tested unit at the same time.

[0023] Another object of the invention is to provide a system that can enable the personnel needed in vehicle services to learn faster with a cumulative information system instead of learning with a master-apprentice method.

[0024] Another object of the invention is to provide a system capable of assisting the service personnel step by step in such a way that the repair can be carried out completely and correctly.

[0025] Another object of the invention is to provide a system which can perform all functional tests of the repaired unit both before and after repair without being attached to the vehicle.

[0026] Another object of the invention is to provide a system which can perform all functional tests of the unit which is estimated to be faulty without removing it from the vehicle.

[0111] In this detailed description, the preferred alternatives of the inventive fault detection and repair test system (20) are described only for a better understanding of the subject matter and without any limiting effect.

[0112] The inventive fault detection and repair test system (20) is configured to provide electronic sensor readings and controls with its electronic and electromechanical compartment (16) and air controls with its pneumatic compartment (15), which are arranged to test and diagnose the tested unit (30) installed or not installed on the vehicle.

[0113] Figure 1 and Figure 2 show views of the fault detection and repair test system (20). Accordingly, the fault detection and repair test system (20) provides connection to the tested unit (30) with air inlet line (27), air outlet line (28), CANBUS- 1, RS485, linBUS connector (4), CANBUS-2, automotive Ethernet IEEE802.X connector (5), sensor reading, solenoid control, power output connector (6) connections to provide air, electrical signal reading or control.

[0114] The artificial intelligence software running on the touch computer (9) communicates with the tested unit (30) via one or more of CANBUS- 1, RS485, LinBUS connector (4) and CANBUS-2, automotive Ethernet IEEE802.X connector (5) according to the methods it has learned, and controls the sensors and solenoids within the tested unit (30). At the same time, it provides the necessary functions by reading or controlling the sensors that can be read directly and solenoids that can be controlled directly without communication within the tested unit (30) via the sensor reading, solenoid control, power output connector (6).

[0115] The software running on the touch computer (9) reads or controls the air pressures on the air inlet line (27) and air outlet line (28) of the fault detection and repair test system (20) via sensor reading unit (92), multiple sensor connection connector (101), proportional solenoid valve control unit (93), multiple proportional solenoid connection connector (102) and / or solenoid valve control unit (94), via multiple solenoid connection connector (103). In this way, the software running on the touch computer (9) within the fault detection and repair test system (20) accomplishes all the control and test operations required for the tested unit (30).

[0116] The software running on the touch computer (9) uses artificial intelligence algorithms for testing and diagnostics to find the current status of the tested unit (30) and, if necessary, the repair operations to be performed. The diagnoses and findings are transmitted to the server (24) via the internet cloud (26).

[0117] The software running on the server (24) is used for training the artificial intelligence running on the server (24) in order to provide more accurate results as the tests performed grow. The server (24) notifies all users of the fault detection and repair test system (20) of new display and repair methods with increasing learning capability. In this way, the fault detection and repair test system (20) is in constant access to more linear results via the server (24).

[0118] By connecting to the fault detection and repair test system (20) via mobile phone (21), remote connection computer (22), tablet (23), test operations can be performed and diagnostic results can be viewed. The fault detection and repair test system (20) is connected to the server (24) via wired Ethernet Router / Switch / HUB (25) or wirelessly via Bluetooth, Wifi IEEE802.i l (18).

[0119] The fault detection and repair test system (20) displays the test result on the touch computer (9) by means of the first speaker (1) and the second speaker (8). The unit under test (30) shows the repair stages audibly and visually with the touch screen computer (9) and the first speaker (1) and the second speaker (8) during the repair process, enabling the service operator to perform the repair operations sequentially and correctly. Running or stopping of the fault detection and repair test system (20) is performed by ON / OFF button (2), emergency stop button (10), on / off switch (14).

[0120] The fault detection and repair test system (20) is connected to the unit under test (30) via air inlet line (27) and air inlet fitting (12). The fault detection and repair test system (20) is connected to the unit under test (30) via the air outlet line (28) and the air outlet fitting (11).

[0121] The fault detection and repair test system (20) displays the test stages in different colours by means of a status light (17) on the unit under test (30) during the test. Due to the large number of connectors and connection hoses required, the fault detection and repair test system (20) is equipped with a material drawer (13).

[0122] The fault detection and repair test system (20) comprises a modular pneumatic compartment (15) and an electronic and electromechanical compartment (16) for operations such as maintenance and repair.

[0123] Since many controls in heavy vehicle systems are provided by air and electronic / electromechanical means, Figure 3 and Figure 4 are interpreted together and the relationship between them is drawn separately without any binding limitations.

[0124] The touch computer (9) is connected to the Ethernet switch (82) via the Ethernet connection connector (84) and / or to the main control unit (81) via the USB connection connector (85). The Ethernet switch (82) is connected to the main control unit (81), sensor reading unit (92), proportional solenoid valve control unit (93), solenoid valve control unit (94) via the ethernet multi-connector (83) using ethernet lines (104) with the first ethernet connection connector (95), second ethernet connection connector (96), third ethernet connection connector (97). In this way, it is ensured that the touch computer (9) can perform high speed and time synchronous communication with the main control unit (81), sensor reading unit (92), proportional solenoid valve control unit (93), solenoid valve control unit (94). At the same time, for the time synchronisation, a secondary communication line is provided with the CANBus connection connector (89) connected between the main control unit (81) and the sensor reading unit (92), proportional solenoid valve control unit (93), solenoid valve control unit (94).

[0125] In order to eliminate time errors caused by the operating system of incoming and outgoing data to and from the touch computer (9), the main control unit (81), sensor reading unit (92), proportional solenoid valve control unit (93), solenoid valve control unit (94) are connected to the CANBus line (91) via the first CANBus connection connector (98), the second CANBus connection connector (99), the third CANBus connection connector (100). The supply voltage, which is the electricity required for the electronic and electromechanical compartment (16), is provided from the power supply (80).

[0126] LinBus connection connector (86), RS485 connection connector (87), Ethernet 802.3 connection connector (88), CANBus connection connector (105) within the main control unit (81) as well as CANBUS-1, RS485, LinBUS connector (4), CANBUS-2, automotive ethernet IEEE802.X connectors (5) within the fault detection and repair test system (20) provide the necessary communication connection for the tested unit (30). The multi-sensor reading connection connector (90) in the main control unit (81) connects to the first pressure sensor (54), second pressure sensor (58), fourth pressure sensor (65) and performs air measurements within the fault detection and repair test system (20) and sends them to the touch computer (9). Thus, the air coming from the tested unit (30) is made suitable for analysis by the second NO solenoid valve (67), second tank (66), pneumatic air inlet fitting (69), silencer fitting (68), and the first pressure sensor (54), second pressure sensor (58), third pressure sensor (62), fourth pressure sensor (65) are read through the electronic and electromechanical compartment (16) and transferred to the touch computer (9) within the fault detection and repair test system (20). The sensor reading unit (92), proportional solenoid valve control unit (93), solenoid valve control unit (94), multi-sensor connection connector (101), multi-proportional solenoid connection connector (102), multi- solenoid connection connector (103) within the fault detection and repair test system (20) are connected to the sensor reading, solenoid control, power output connector (6). In this way, the sensor information required for the unit under test (30) and regulated air pressure operations are provided.

[0127] The proportional solenoid valve control unit (93) is connected to the proportional valve (59) via the proportional solenoid connection connector (102) and adjusts the pressure of the air passing through each pneumatic air supply fitting (63). The solenoid valve control unit (94) controls the first NC solenoid valve (52), the second NC solenoid valve (57), the third NC solenoid valve (61), the first NO solenoid valve (64), the second NO solenoid valve (67) via the multiple solenoid connection connector (103).

[0128] The air entering from outside is allowed to enter the pneumatic compartment (15) with the pneumatic air inlet curtain fitting (51). The first NC solenoid valve (52), second NC solenoid valve (57), third NC solenoid valve (61) are normally closed and are closed when there is no energy in the system. The first NO solenoid valve (64) and the second NO solenoid valve (67) are open when the system is not energised. In this way, uncontrolled activation and deactivation of the fault detection and repair test system (20) is prevented when the system is not energised.

[0129] In case the emergency button (10) of the fault detection and repair test system (20) is pressed, the first NC solenoid valve (52), the second NC solenoid valve (57), the third NC solenoid valve (61) are configured to be normally closed and the necessary safety criteria are provided. The first NC solenoid valve (52), the second NC solenoid valve (57), the third NC solenoid valve (61), the first NO solenoid valve (64) and the second NO solenoid valve (67) are connected to the solenoid valve control unit (94) via the multi-sensor connection connector (101). In this way, the first NC solenoid valve (52), the second NC solenoid valve (57), the third NC solenoid valve (61), the first NO solenoid valve (64) and the second NO solenoid valve (67) connected to the solenoid valve control unit (94) are controlled by commands from the touch computer (9) or the main control unit (81). Similarly, the commands from the touch computer (9) or the main control unit (81) are used to control the proportional pressure control via the proportional solenoid valve control unit (93), and the proportional valve (59) is controlled via the multiple proportional solenoid connection connector (102).

[0130] The air coming from the first NC solenoid valve (52) is provided to pass through the conditioner (53) in one direction. The outlet of the conditioner (53) enters the booster (55) and the booster (55) increases the pressure by compressing the air coming to the inlet to provide at least 1.5 times pressure and stores it in the first tank (56). The outlet of the first tank (56) is kept at the inlet of the NC solenoid valve (57). When the NC solenoid valve (57) is opened with the received command, it reaches the proportional valve (59) inlet. The proportional solenoid valve adjusts the desired pressure depending on the pressure information from the control unit (93).

[0131] The output of the proportional valve (59) is connected to the pneumatic air check valve (60), and the pneumatic air check valve (60) provides one-way movement of the incoming air. The air at the outlet of the pneumatic air check valve (60) reaches the inlet of the third NC solenoid valve (61). The third NC solenoid valve (61) is controlled by the signal from the solenoid valve control unit (94). The output of the third NC solenoid valve (61) supplies air via the air inlet fitting (12) to the air inlet of the unit under test (30) to be tested via the pneumatic air supply fitting (63). Similarly, the third NC solenoid valve (61) is closed and the first NO solenoid valve (64) is opened to discharge the air in the unit under test (30) and the air is discharged to the air inlet fitting (12) on the fault detection and repair test system (20). The tested unit (30), the air coming from the air outlet fittings (11) reaches the second tank (66) via the pneumatic air inlet fitting (69). The air in the second tank (66) is discharged to the external environment after the second NO solenoid valve (67) is controlled by the solenoid valve control unit (94) and the test process is terminated with the silencer fitting (68). The air connections between the unit under test (30) and the fault detection and repair test system (20) are provided by air inlet line (27) and air outlet line (28).

[0132] Pneumatic air line (50) shows the line where the air circulates.
