The board-to-board connector may include at least two boards, on which a circuit board, a plug, and a socket are arranged. The two boards are connected by snapping together, so that the corresponding plug and socket are docked, thereby realizing the transmission of power supply, communication, clock signals, etc. between the two circuit boards.

[0043] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and in detail below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0044] In the first aspect, the present application provides a reliability test system for a cockpit controller 20, referring to Figure 1 The reliability test system includes a vibration platform 12, a host 11 and a cockpit controller 20, the host 11 and the vibration platform 12 and the cockpit controller 20 are all in communication connection, the cockpit controller 20 includes a board-to-board connector 21, a signal generating module 22, a signal receiving module 23 and a judgment processing module 23, the judgment processing module 23 is in communication connection with the signal generating module 22 and the signal receiving module 23;

[0045] The vibration platform 12 is used to carry the cockpit controller 20, and the host 11 is used to send a detection instruction to the cockpit controller 20 and a start instruction to the vibration platform 12 after the cockpit controller 20 has been fixed on the vibration platform 12; in response to the start instruction, the vibration platform 12 starts to vibrate;

[0046] In response to the detection instruction, the signal generating module 22 is used to continuously generate a constant initial voltage signal within a preset time period and send it to the input end of the board-to-board connector 21, the signal receiving module 23 is used to obtain a real-time voltage signal from the output end of the board-to-board connector 21 within a preset time period, and the judgment processing module 23 is used to generate and store a detection result according to the initial voltage signal and the real-time voltage signal;

[0047] The host 11 is also used to access the cockpit controller 20 after a preset time period to obtain the test result, and determine whether the cockpit controller 20 passes the reliability test according to the test result.

[0048] Through the above technical solution, by vibrating the vibration platform 12, the vibration environment of the whole vehicle during operation can be simulated, and the cockpit controller 20 can be put into a vibrating state. The vibration can disconnect the board-to-board connector 21 in an unreliable connection state, that is, it can disconnect the board-to-board connector 21 in a semi-connected state. Therefore, by detecting the cockpit controller 20 in a vibrating state, it is possible to detect whether the board-to-board connector 21 is in an unreliable connection state, thereby being able to detect whether the cockpit controller 20 is in an unreliable connection state, thereby reducing the risk of the car failing due to the cockpit controller 20. Moreover, based on the above technical solution, since the test results are stored in the cockpit controller 20, on the one hand, in the subsequent testing or production process of the cockpit controller 20, it is still possible to reconfirm whether the cockpit controller 20 has passed the connection reliability test by accessing the cockpit controller 20, thereby reducing the risk of the bad cockpit controller 20 flowing out, thereby reducing the risk of the car failing due to the cockpit controller 20. On the other hand, there is no need for frequent communication between the host 11 and the cockpit controller 20. The host 11 only needs to send a detection command to the cockpit controller 20 before starting the detection, and after completing the detection, the detection result can be obtained through one communication with the cockpit controller 20. Then, it can be determined whether the cockpit controller 20 has passed the reliability test based on the detection result, thereby reducing the communication cost during the reliability detection of the cockpit controller 20.

[0049] It should be understood that the unreliable connection of the board-to-board connector 21 refers to the unreliable connection between the two connecting parts of the board-to-board connector 21. In a static environment, a good conductive connection can be achieved between the two connecting parts, but in a vibrating environment, the two connecting parts are easily separated from each other due to vibration, resulting in failure of the conductive connection.

[0050] In a possible embodiment, the signal receiving module 23 obtains multiple real-time voltage signals at a preset frequency within a preset time period; the detection result includes the identity of the cockpit controller 20 and multiple sub-results, and the multiple sub-results correspond to the multiple real-time voltage signals one by one. Based on this solution, it can be seen that the judgment processing module 23 can generate a sub-result based on a real-time voltage signal and an initial voltage signal. The judgment processing module 23 can generate the same number of sub-results as the number of real-time voltage signals obtained by the signal receiving module 23. The judgment processing module 23 combines the sub-results and the identity of the cockpit controller 20 to form the detection result of the cockpit controller 20 for query by the host 11.

[0051] The signal receiving module 23 acquires multiple real-time voltage signals at a preset frequency within a preset time period, which can be understood as acquiring real-time voltage signals at a preset period within a preset time period. For example, the preset time period is five minutes, and the real-time voltage signal is acquired every two seconds within the five minutes.

[0052] In one embodiment, the judgment processing module 23 calculates the difference between the voltage value of the initial voltage signal and the voltage value of each real-time voltage signal, and generates a sub-result by judging whether each difference exceeds the error range. It should be understood that the two connecting parts of the board-to-board connector 21 are connected by reliable mechanical connection to achieve reliable conductive contact between internal electrical components; when the electrical components are in reliable conductive contact, the board-to-board connector 21 can transfer the voltage signal obtained from the input end to the output end within a known loss range. If the conductive contact between the electrical components is poor, the voltage signal transmission loss is large, and there will be a large deviation between the voltage signal output from the output end and the voltage signal at the input end. Therefore, the error range can be set in advance according to the loss characteristics of the board-to-board connector 21 itself. If the difference between the voltage value of the initial voltage signal and the voltage value of the real-time voltage signal is within the error range, it means that the two connecting parts of the board-to-board connector 21 are reliably connected, and the internal electrical components are in reliable conductive contact, and the judgment processing module 23 generates a sub-result indicating reliable connection. If the difference between the voltage value of the initial voltage signal and the voltage value of the real-time voltage signal exceeds the error range, it means that the two connecting parts of the board-to-board connector 21 are not reliably connected, and there is no reliable conductive contact between the internal electrical components, and the judgment processing module 23 generates a sub-result indicating a fault. Among them, reliable conductive contact between internal electrical components can be understood as: the conductive contact area between the electrical components on the two connecting parts of the board-to-board connector 21 is within a preset range, and if it exceeds the preset range, it can be considered that the conductive contact is unreliable.

[0053] Regarding the host 11 judging whether the cockpit controller 20 has passed the reliability test according to the test result, the specific implementation method may include: judging whether there is a sub-result indicating a fault in the test result; if so, judging that the cockpit controller 20 has not passed the reliability test; if not, judging that the cockpit controller 20 has passed the reliability test. That is, as long as there is a sub-result indicating a fault in the test result, it means that the connection reliability of the cockpit controller 20 does not meet the requirements and has not passed the reliability test.

[0054] In one example, in response to the start-up instruction, the vibration platform 12 stops vibrating after a preset time period. That is, the vibration platform 12 can automatically stop vibrating after vibrating for a preset period of time according to the start-up instruction.

[0055] Alternatively, in another example, the host 11 is also used to send a stop instruction to the vibration platform 12 after a preset time period, and the vibration platform 12 stops vibrating in response to the stop instruction. That is, the host 11 can stop the vibration platform 12 from vibrating by sending a stop instruction after a preset time period.

[0056] The host 11 may send out a detection instruction and a start instruction at the same time, or may send out a detection instruction first and then send out a start instruction.

[0057] Among them, the mechanical connection between the cockpit controller 20 and the vibration platform 12 can be set by those skilled in the art according to actual conditions, and this application does not limit it.

[0058] In one example, a start button may be provided on the host 11. When the cockpit controller 20 has been fixed on the vibration platform 12, the staff may press the start button. When the start button is pressed, the host 11 may generate a detection instruction and a start instruction. Furthermore, the reliability test system provided by the present application may also include a sensor, which may be used to sense whether the cockpit controller 20 has been fixed on the vibration platform 12. If so, after the start button is pressed, the host 11 may generate a detection instruction and a start instruction; if not, even if the start button is pressed, the host 11 does not generate a detection instruction and a start instruction.

[0059] The vibration platform 12 can complete vibrations in the three directions of X, Y, and Z within a preset time period. The vibration platform 12 can perform vibration work in accordance with relevant international standards, and can perform vibration work in accordance with relevant international standards. Among them, the three directions of X, Y, and Z are perpendicular to each other. Vibration power spectral density (PSD) is a parameter that describes the frequency domain characteristics of random vibration signals. It indicates the power within a unit frequency band, usually in units of watts per hertz (W / Hz) or watts per hertz per square meter (W / Hz / m 2 ) as a unit and can be expressed as a function of frequency. The following table is a vibration power spectrum density table provided by the present application, and the user can select any data from the following table as the vibration data of the vibration platform 12 at a certain moment and in a certain direction. Figure 2 A power spectral density graph based on the table below is provided.

[0060]

[0061] In addition, the test system of the present application may further include a power supply and a rack 31, the power supply and the host 11 are both arranged on the rack 31, and the power supply and the cockpit controller 20 and the host 11 are all electrically connected to provide power to the cockpit controller 20 and the host 11. The power supply may provide power to the cockpit controller 20 through a conductive cable 33. The host 11 may achieve communication connection with the cockpit controller 20 through a communication bus 32.

[0062] Second, refer to Figure 3The present application also provides a cockpit controller 20, which includes a board-to-board connector 21, a signal generating module 22, a signal receiving module 23 and a judgment processing module 23: the signal generating module 22 is electrically connected to the input end of the board-to-board connector 21, and the signal generating module 22 is used to continuously generate a constant initial voltage signal within a preset time period and send it to the input end of the board-to-board connector 21; the signal receiving module 23 is electrically connected to the output end of the board-to-board connector 21, and is used to obtain a real-time voltage signal within a preset time period; the judgment processing module 23 is electrically connected to the signal generating module 22 and the signal receiving module 23 to obtain an initial voltage signal and a real-time voltage signal, and the signal receiving module 23 is used to generate and store a detection result based on the initial voltage signal and the real-time voltage signal.

[0063] Based on the above technical solution, it can be known that since the test results are stored in the cockpit controller 20, on the one hand, in the subsequent test or production process of the cockpit controller 20, it is possible to confirm whether the cockpit controller 20 has passed the connection reliability test by accessing the cockpit controller 20, thereby reducing the risk of the bad cockpit controller 20 flowing out, thereby reducing the risk of the car failing due to the cockpit controller 20. On the other hand, in the test system or production system of the cockpit controller 20, there is no need for frequent communication between the system main controller and the cockpit controller 20. The system main controller only needs to issue a test command to the cockpit controller 20 before starting the test, and after the test is completed, the test result can be obtained through one communication with the cockpit controller 20, and then it can be determined whether the cockpit controller 20 has passed the reliability test based on the test result, thereby reducing the communication cost in the reliability test process of the cockpit controller 20.

[0064] When testing the cockpit controller 20 specifically, the cockpit controller 20 can be placed on a vibration platform 12. By vibrating the vibration platform 12, the vibration environment of the entire vehicle during operation can be simulated, and the cockpit controller 20 can be placed in a vibrating state. The vibration can disconnect the board-to-board connector 21 that is in an unreliable connection state, that is, it can disconnect the board-to-board connector 21 that is in a semi-connected state. Therefore, by testing the cockpit controller 20 in a vibrating state, it is possible to detect whether the board-to-board connector 21 is in an unreliable connection state, thereby being able to detect whether the cockpit controller 20 is in an unreliable connection state, thereby reducing the risk of vehicle failure due to the cockpit controller 20.

[0065] In a possible embodiment, the signal receiving module 23 obtains multiple real-time voltage signals at a preset frequency within a preset time period; the detection result includes the identity of the cockpit controller 20 and multiple sub-results, and the multiple sub-results correspond to the multiple real-time voltage signals one by one. Based on this solution, it can be seen that the judgment processing module 23 can generate a sub-result based on a real-time voltage signal and an initial voltage signal. The judgment processing module 23 can generate the same number of sub-results as the number of real-time voltage signals obtained by the signal receiving module 23. The judgment processing module 23 combines the sub-results and the identity of the cockpit controller 20 to form the detection result of the cockpit controller 20 for query by the host 11.

[0066] The signal receiving module 23 acquires multiple real-time voltage signals at a preset frequency within a preset time period, which can be understood as acquiring real-time voltage signals at a preset period within a preset time period. For example, the preset time period is one hour, and the real-time voltage signal is acquired every two minutes within this hour.

[0067] In one example, the cockpit controller 20 may include a programmable read-only memory, and the detection result generated by the judgment processing module 23 may be stored in the programmable read-only memory.

[0068] In the third aspect, the present application also provides a reliability test method for a cockpit controller 20, wherein the cockpit controller 20 includes a board-to-board connector 21, a signal generating module 22, a signal receiving module 23, and a judgment processing module 23, wherein the judgment processing module 23 is communicatively connected to the signal generating module 22 and the signal receiving module 23, and the reference Figure 4 , the reliability test method includes:

[0069] S41, fixing the cockpit controller 20 on the vibration platform 12;

[0070] S42, sending a detection instruction to the cockpit controller 20 through the host 11, and sending a start instruction to the vibration platform 12. In response to the start instruction, the vibration platform 12 starts to vibrate. In response to the detection instruction, the signal generating module 22 of the cockpit controller 20 continuously generates a constant initial voltage signal within a preset time period and sends it to the input end of the board-to-board connector 21. The signal receiving module 23 of the cockpit controller 20 obtains a real-time voltage signal from the output end of the board-to-board connector 21 within a preset time period. The judgment processing module 23 of the cockpit controller 20 generates and stores a detection result according to the initial voltage signal and the real-time voltage signal.

[0071] S43, the host 11 accesses the cockpit controller 20 after a preset time period to obtain the test result, and determines whether the cockpit controller 20 passes the reliability test according to the test result.

[0072] Through the above technical solution, by vibrating the vibration platform 12, the vibration environment of the whole vehicle during operation can be simulated, and the cockpit controller 20 can be put into a vibrating state. The vibration can disconnect the board-to-board connector 21 in an unreliable connection state, that is, it can disconnect the board-to-board connector 21 in a semi-connected state. Therefore, by detecting the cockpit controller 20 in a vibrating state, it is possible to detect whether the board-to-board connector 21 is in an unreliable connection state, thereby being able to detect whether the cockpit controller 20 is in an unreliable connection state, thereby reducing the risk of the car failing due to the cockpit controller 20. Moreover, based on the above technical solution, since the test results are stored in the cockpit controller 20, on the one hand, in the subsequent testing or production process of the cockpit controller 20, it is still possible to reconfirm whether the cockpit controller 20 has passed the connection reliability test by accessing the cockpit controller 20, thereby reducing the risk of the bad cockpit controller 20 flowing out, thereby reducing the risk of the car failing due to the cockpit controller 20. On the other hand, there is no need for frequent communication between the host 11 and the cockpit controller 20. The host 11 only needs to send a detection command to the cockpit controller 20 before starting the detection, and after the detection is completed, the detection result can be obtained through one communication with the cockpit controller 20, and then it can be determined whether the cockpit controller 20 passes the reliability test based on the detection result. Therefore, the communication cost in the reliability detection process of the cockpit controller 20 can be reduced.

[0073] In a possible embodiment, the signal receiving module 23 obtains multiple real-time voltage signals at a preset frequency within a preset time period; the detection result includes the identity of the cockpit controller 20 and multiple sub-results, and the multiple sub-results correspond to the multiple real-time voltage signals one by one. Based on this solution, it can be seen that the judgment processing module 23 can generate a sub-result based on a real-time voltage signal and an initial voltage signal. The judgment processing module 23 can generate the same number of sub-results as the number of real-time voltage signals obtained by the signal receiving module 23. The judgment processing module 23 combines the sub-results and the identity of the cockpit controller 20 to form the detection result of the cockpit controller 20 for query by the host 11.

[0074] The signal receiving module 23 acquires multiple real-time voltage signals at a preset frequency within a preset time period, which can be understood as acquiring real-time voltage signals at a preset period within a preset time period. For example, the preset time period is five minutes, and the real-time voltage signal is acquired every two seconds within the five minutes.

[0075] In one embodiment, the judgment processing module 23 calculates the difference between the voltage value of the initial voltage signal and the voltage value of each real-time voltage signal, and generates a sub-result by judging whether each difference exceeds the error range. It should be understood that the two connecting parts of the board-to-board connector 21 are connected by reliable mechanical connection to achieve reliable conductive contact between internal electrical components; when the electrical components are in reliable conductive contact, the board-to-board connector 21 can transfer the voltage signal obtained from the input end to the output end within a known loss range. If the conductive contact between the electrical components is poor, the voltage signal transmission loss is large, and there will be a large deviation between the voltage signal output from the output end and the voltage signal at the input end. Therefore, the error range can be set in advance according to the loss characteristics of the board-to-board connector 21 itself. If the difference between the voltage value of the initial voltage signal and the voltage value of the real-time voltage signal is within the error range, it means that the two connecting parts of the board-to-board connector 21 are reliably connected, and the internal electrical components are in reliable conductive contact, and the judgment processing module 23 generates a sub-result indicating reliable connection. If the difference between the voltage value of the initial voltage signal and the voltage value of the real-time voltage signal exceeds the error range, it means that the two connecting parts of the board-to-board connector 21 are not reliably connected and there is no reliable conductive contact between the internal electrical components, and the judgment processing module 23 generates a sub-result indicating a fault.

[0076] Regarding the host 11 judging whether the cockpit controller 20 has passed the reliability test according to the test result, the specific implementation method may include: judging whether there is a sub-result indicating a fault in the test result; if so, judging that the cockpit controller 20 has not passed the reliability test; if not, judging that the cockpit controller 20 has passed the reliability test. That is, as long as there is a sub-result indicating a fault in the test result, it means that the connection reliability of the cockpit controller 20 does not meet the requirements and has not passed the reliability test.

[0077] In one example, in response to the start-up instruction, the vibration platform 12 stops vibrating after a preset time period. That is, the vibration platform 12 can automatically stop vibrating after vibrating for a preset period of time according to the start-up instruction.

[0078] Alternatively, in another example, the host 11 is also used to send a stop instruction to the vibration platform 12 after a preset time period, and the vibration platform 12 stops vibrating in response to the stop instruction. That is, the host 11 can stop the vibration platform 12 from vibrating by sending a stop instruction after a preset time period.

[0079] The host 11 may send out a detection instruction and a start instruction at the same time, or may send out a detection instruction first and then send out a start instruction.
