[0039] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements.

[0040] The embodiments described in the following examples of the present disclosure do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0041] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0042] For vehicles, the suspension system needs to be tested. A suspension HIL test bench can be built to test the suspension system of the vehicle, so as to perform functional testing, fault injection, diagnostic testing and stress testing verification on the controller in the suspension system, thereby improving development efficiency and reducing development resources.

[0043] In the prior art, suspension HIL test benches require multiple expansion devices to implement different test scenarios. Each expansion device requires a custom board to process data, resulting in high test bench costs.

[0044] In response to the above technical problems, the embodiments of the present disclosure provide a test bench and a test data processing method. The data transfer device can process the data transmitted from the first device such as the host computer, the suspension system and various expansion peripherals, and convert it into a target signal that matches the communication method of the second device. There is no need to configure various different boards, thereby reducing the cost of the test bench.

[0045] Figure 1 is a schematic structural diagram of a stand according to an exemplary embodiment. Figure 1 As shown, it may include a host computer 1, a suspension system 2, a data transfer device 3 and an extended peripheral device 4.

[0046] The host computer 1, the suspension system 2, and the extended peripherals 4 are all connected to the data transfer device 3 so that the data transfer device 3 can receive the data to be processed transmitted by the host computer 1, the suspension system 2, and the extended peripherals 4. The communication method between the host computer 1 and the data transfer device 3 can be CAN (Controller Area Network) communication or TCP (Transmission Control Protocol) communication, and the communication method between the suspension system 2 and the data transfer device 3 can be CAN communication. Because different extended peripherals 4 may use different communication methods, the communication method between the extended peripherals 4 and the data transfer device 3 can be CAN communication, serial port communication, or IO (Input / Output) control communication. For example, the expansion device may include a motor, a relay, an ammeter 410, a three-way valve and a pressure gauge, wherein the communication method between the motor and the three-way valve and the data transfer device 3 can be IO control communication, the communication method between the relay and the pressure gauge and the data transfer device 3 can be serial communication, and the communication method between the ammeter 410 and the data transfer device 3 can be CAN communication. The extended peripherals 4 required for the test, such as relays, power supplies 5, motors, three-way valves, ammeters 410, pressure gauges, etc., all support communication and data transmission. The mainstream ones are serial communication, CAN communication and TCP communication. CAN communication and serial communication support one-to-many communication and can be identified by simply changing the address, which can effectively reduce the interface resources consumed by the data transfer device 3. All extended peripherals 4 are connected to the data transfer device 3. The data transfer device 3 processes and routes the communication data, and finally unifies it into CAN communication. The DBC (Database Canonicalization) file required for communication is defined and transmitted to the CAN path of the host computer 1, the data transfer device 3 and the suspension system 2. The communication protocol is unified, supporting the host computer 1 to perform automated testing on the suspension system 2.

[0047] Among them, the data transfer device 3 can be a real-time machine. The data transfer device 3 can receive the data to be processed sent by the first device for the second device, process the data to be processed, obtain the target signal that matches the communication method of the second device, and send the target signal to the second device. Among them, the first device can be any one of the host computer 1, the suspension system 2, and the extended peripheral device 4, and the second device can be at least one of the host computer 1, the suspension system 2, and the extended peripheral device 4 except the first device. That is, the host computer 1 can send data to the suspension system 2 and the extended peripheral device 4 at the same time, or send data to the suspension system 2 and the extended peripheral device 4 separately; the suspension system 2 can send data to the host computer 1 and the extended peripheral device 4 at the same time, or send data to the host computer 1 and the extended peripheral device 4 separately; the extended peripheral device 4 can send data to the host computer 1 and the suspension system 2 at the same time, or send data to the host computer 1 and the extended peripheral device 4 separately.

[0048] In this embodiment, the data transfer device 3 can process the data transmitted from the host computer 1, the suspension system 2 and various expansion peripherals 4 to obtain a target signal that matches the communication method of the target device transmitted, without the need to configure various different boards, thereby reducing the cost of the test stand.

[0049] In one possible implementation, the host computer 1 and the extended peripheral device 4 are both connected to the suspension system 2. At this time, the host computer 1 can communicate directly with the suspension system 2, and the extended peripheral device 4 can also communicate directly with the suspension system 2. In this case, the first device can be the suspension system 2, and the second device can be the extended peripheral device 4; or, the first device can be the extended peripheral device 4, and the second device can be the host computer 1; or, the first device can be the host computer 1, and the second device can be the extended peripheral device 4.

[0050] In one possible implementation, the data transfer device can process the data to be processed through an information processing model, obtain a target signal that matches the communication method of the second device, and send the target signal to the second device. The information processing model can be constructed based on the configuration data sent by the host computer 1. Specifically, the configuration data may include data conversion relationships between multiple different communication methods, and the information processing model can be constructed based on the configuration data so that the information processing model can realize data conversion between different communication methods. The configuration data can be obtained based on the user's input data obtained by the host computer 1, that is, the user can directly write code on the host computer 1 to input configuration data to the host computer 1; in addition, the configuration data can also be downloaded from the target platform based on the host computer 1.

[0051] In this embodiment, the data transfer device 3 can construct an information processing model based on the configuration data sent by the host computer 1. Through the information processing model, the data transmitted from the first device such as the host computer 1, the suspension system 2 and various extended peripherals 4 can be processed and converted into a target signal that matches the communication method of the second device. There is no need to configure various different boards and cards, thereby reducing the cost of the test stand.

[0052] Figure 2 is a schematic structural diagram of another stand according to an exemplary embodiment. Figure 3 FIG. 1 is a schematic diagram showing a suspension height adjustment according to an exemplary embodiment. Figure 2 and Figure 3 As shown, in a possible implementation, the suspension system 2 includes a suspension controller 21 , an air spring 22 and a height sensor 24 , and the extended peripheral device 4 includes a first motor 41 .

[0053] The air spring 22, height sensor 24, host computer 1, and data transfer device 3 are all connected to the suspension controller 21. The air spring 22 can be inflated through the suspension controller 21, and the suspension controller 21 can obtain the height value detected by the height sensor 24. The suspension controller 21 can receive data sent by the host computer 1 and send data to the host computer 1 and data transfer device 3.

[0054] Among them, the first motor 41 can be an open-loop motor, and there can be multiple first motors 41. For example, there can be four first motors 41, corresponding to the left front, right front, left rear and right rear of the vehicle respectively, and one first motor 41 corresponds to one height sensor 24. For each first motor 41, the first end of the first motor 41 is connected to the height sensor 24, and the second end of the first motor 41 is connected to the data transfer device 3. For the height control test of the suspension, the host computer 1 can send height adjustment information to the suspension controller 21. For example, the height adjustment information is: adjust to a comfortable height. After receiving the height adjustment information, the suspension controller 21 can generate control data, including the target height corresponding to the height adjustment information and the first data to be processed for the first motor 41. The first data to be processed can be an adjustment instruction to control the rotation of the first motor 41. The communication method can be CAN communication.

[0055] In one possible embodiment, the suspension system 2 may further include an air tank 23 . The air tank 23 is connected to the air spring 22 and is used to inflate the air spring 22 . The suspension controller 21 may control the air tank 23 to inflate the air spring 22 .

[0056] In one possible embodiment, the suspension system 2 may further include a limiting structure 25. The air spring 22 is disposed in the limiting structure 25, which is used to limit the height of the air spring 22. Specifically, the limiting structure 25 may include two parallel steel plates, between which the air spring 22 is sandwiched at an initial height. One end of the air spring 22 is connected to the upper steel plate, and the other end of the air spring 22 is connected to the lower steel plate to simulate a load. The distance between the two parallel steel plates is fixed and can withstand a preset weight, for example, 5 tons, so as to exceed the weight of the vehicle with a margin. The distance between the two parallel steel plates does not change with changes in the air pressure in the air spring 22.

[0057] In one possible embodiment, the expansion peripheral device 4 may further include a first three-way valve 42, a first end of the first three-way valve 42 being connected to the suspension controller 21, and a second end of the first three-way valve 42 being connected to the air spring 22, and the first three-way valve 42 being used to deflate the air spring 22. The suspension controller 21 may control the first three-way valve 42 to open, thereby deflating the air spring 22.

[0058] The data transfer device 3 can receive the first data to be processed for the first motor 41 sent by the suspension controller 21, and process the first data to be processed through the information processing model to obtain a first target signal that matches the communication method of the first motor 41. The first data to be processed can be an adjustment instruction for controlling the rotation of the first motor 41. The communication method can be IO control communication, and the first target signal is sent to the first motor 41. The first target signal is used to control the rotation of the first motor 41 to adjust the vehicle body height information obtained by the suspension controller 21 from the first motor 41.

[0059] Specifically, the first direction of rotation can be set to raise, and the second direction of rotation can be set to lower. The first direction of rotation can be forward, and the second direction of rotation can be reverse; alternatively, the first direction of rotation can be reverse, and the second direction of rotation can be forward. The rotation speed can be a preset speed, and the height value corresponding to one rotation can be set. The height sensor 24 is connected to the first motor 41. Specifically, it can be located on the rotating shaft of the first motor 41. Rotation of the first motor 41 drives the height sensor 24. The height sensor 24 detects the rotation of the first motor 41 and obtains a corresponding vehicle height value. The height sensor 24 transmits the detected vehicle height value to the suspension controller 21, allowing the suspension controller 21 to obtain vehicle height information. If the vehicle height information obtained by the suspension controller 21 is equal to the target height, the suspension controller 21 sends a control command, which is transmitted to the data transfer device 3 to the first motor 41 to stop the first motor 41. The suspension controller 21 then transmits the final vehicle height information to the host computer 1, allowing the host computer 1 to determine whether the vehicle height control result is accurate.

[0060] By decoupling the motor from the air spring 22 , the requirements for the motor can be reduced. The first motor 41 can rotate to simulate the vehicle height adjustment, thereby greatly reducing the cost and size of the motor.

[0061] In a possible implementation, the extended peripheral device 4 further includes a first pressure gauge 43 .

[0062] The first pressure gauge 43 is arranged between the first three-way valve 42 and the air spring 22, and the first pressure gauge 43 is connected to the data transfer device 3, for detecting the pressure value of the air spring 22, obtaining the second data to be processed, and transmitting the second data to be processed to the data transfer device 3.

[0063] The data transfer device 3 is used to receive the second data to be processed sent by the first pressure gauge 43 to the host computer 1. The communication mode of the second data to be processed can be serial communication, and the second data to be processed is processed through the information processing model to obtain a second target signal that matches the communication mode of the host computer 1. The communication mode of the second target signal can be CAN communication, and the second target signal is sent to the host computer 1. The second target signal is used by the host computer 1 to determine whether the pressure value of the air spring 22 is greater than the pressure threshold.

[0064] Through the above method, the first pressure gauge 43 can detect the pressure of the air spring 22 and upload it to the host computer 1. The host computer 1 can judge the pressure value of the air spring 22. If the pressure value of the air spring 22 is greater than the pressure threshold corresponding to the air spring 22, a control instruction can be issued through the data transfer device 3 to the first three-way valve 42 to control the first three-way valve 42 to open and deflate the air spring 22, thereby controlling the pressure value of the air spring 22 to be less than or equal to the pressure threshold of the air spring 22.

[0065] Specifically, the first three-way valve 42 is connected to the data transfer device 3 .

[0066] The data transfer device 3 is used to receive the third data to be processed for the first three-way valve 42 sent by the upper computer 1, and process the third data to be processed through the information processing model to obtain a third target signal that matches the communication mode of the first three-way valve 42, and send the third target signal to the first three-way valve 42. The third target signal is used to control the first three-way valve 42 to deflate the air spring 22, thereby controlling the pressure value of the air spring 22 to be less than or equal to the pressure threshold of the air spring 22.

[0067] In a possible implementation, the extended peripheral device 4 further includes a second three-way valve 44 and a second pressure gauge 45 .

[0068] A first end of the second three-way valve 44 is connected to the suspension controller 21 , and a second end of the second three-way valve 44 is connected to the air storage tank 23 . The second three-way valve 44 is used to deflate the air storage tank 23 .

[0069] The second pressure gauge 45 is disposed between the second three-way valve 44 and the gas storage tank 23 , and is connected to the data transfer device 3 , for detecting the pressure value of the gas storage tank 23 and transmitting the detected pressure value to the data transfer device 3 .

[0070] The data transfer device 3 can be used to receive the data to be processed sent by the second pressure gauge 45 to the host computer 1. The communication mode of the data to be processed can be serial communication, and the data to be processed is processed through the information processing model to obtain a target signal that matches the communication mode of the host computer 1. The communication mode of the target signal can be CAN communication, and the target signal is sent to the host computer 1. The target signal is used by the host computer 1 to determine whether the pressure value of the gas tank 23 is greater than the pressure threshold of the gas tank 23.

[0071] Through the above method, the second pressure gauge 45 can detect the pressure of the gas tank 23 and upload it to the host computer 1. The host computer 1 can judge the pressure value of the gas tank 23. If the pressure value of the gas tank 23 is greater than the pressure threshold corresponding to the gas tank 23, a control instruction can be issued to the second three-way valve 44 through the data transfer device 3 to control the second three-way valve 44 to open and deflate the gas tank 23, thereby controlling the pressure value of the gas tank 23 to be less than or equal to the pressure threshold of the gas tank 23.

[0072] Specifically, the second three-way valve 44 is connected to the data transfer device 3 .

[0073] The data transfer device 3 is used to receive the fourth data to be processed for the second three-way valve 44 sent by the upper computer 1, and process the fourth data to be processed through the information processing model to obtain a fourth target signal that matches the communication mode of the second three-way valve 44, and send the fourth target signal to the second three-way valve 44. The fourth target signal is used to control the second three-way valve 44 to deflate the gas tank 23, thereby controlling the pressure value of the gas tank 23 to be reduced to less than or equal to the pressure threshold of the gas tank 23.

[0074] In a possible implementation, the extended peripheral device 4 further includes a first relay group 46 . One height sensor 24 corresponds to one first relay group 46 .

[0075] The first relay group 46 is provided between the height sensor 24 and the suspension controller 21 and is connected to the data transfer device 3 so that the host computer 1 can transmit control instructions to the first relay group 46 through the data transfer device 3 .

[0076] When fault injection related to the first relay group 46 is required, the upper computer 1 can send a fault control instruction to the data transfer device 3. The data transfer device 3 is used to receive the fifth data to be processed for the first relay group 46 sent by the upper computer 1, and process the fifth data to be processed through the information processing model to obtain a fifth target signal that matches the communication method of the first relay group 46, and send the fifth target signal to the first relay group 46. The fifth target signal is used to control the on and off state of the first relay group 46 for fault injection.

[0077] Figure 4 FIG. 4 is a schematic diagram showing a connection structure of a first relay group 46 according to an exemplary embodiment. Figure 4 As shown, the first relay group 46 may include a first relay, a second relay, and a third relay. The first relay is provided on the ground line of the height sensor 24, the second relay is provided on the connection line between the height sensor 24 and the suspension controller 21, and the third relay is provided on the power supply line of the height sensor 24. By controlling the first relay to open, a short-to-ground fault can be injected into the height sensor 24; by controlling the second relay to open, an open-circuit fault can be injected into the height sensor 24; and by controlling the third relay to open, a short-to-power-5 fault can be injected into the height sensor 24. The host computer 1 can then obtain the control results of the suspension controller 21 in response to the fault to determine whether the control results of the suspension controller 21 in response to the fault are accurate. The first and third relays are not opened at the same time.

[0078] In a possible implementation, the suspension system 2 further includes an acceleration sensor, and the extended peripheral device 4 further includes a second motor 47 .

[0079] The suspension controller 21 is connected to the acceleration sensor; the first end of the second motor 47 is connected to the acceleration sensor, and the second end of the second motor 47 is connected to the data transfer device 3. This allows the suspension controller 21 to send control instructions to the second motor 47 through the data transfer device 3. The second motor can be an open-loop motor.

[0080] The data transfer device 3 can receive the sixth data to be processed for the second motor 47 sent by the suspension controller 21, and process the sixth data to be processed through the information processing model to obtain a sixth target signal that matches the communication method of the second motor 47, and send the sixth target signal to the second motor 47. The sixth target signal is used to control the rotation of the second motor 47 to adjust the vehicle body posture information obtained by the suspension controller 21 from the second motor 47.

[0081] There may be multiple second motors 47. For example, there may be three second motors 47, one for each of the left front, right front, and rear of the vehicle. Each second motor 47 corresponds to one acceleration sensor. For each second motor 47, the first end of the second motor 47 is connected to the acceleration sensor, and the second end of the second motor 47 is connected to the data transfer device 3. For the suspension posture control test, the host computer 1 may send posture adjustment information to the suspension controller 21. After receiving the posture adjustment information, the suspension controller 21 may generate control data, including the target posture corresponding to the posture adjustment information and sixth data to be processed for the second motor 47. The sixth data to be processed may be an adjustment instruction for controlling the rotation of the second motor 47. The communication method may be CAN communication. The data transfer device 3 is used to receive the sixth data to be processed for the second motor 47 sent by the suspension controller 21, and process the sixth data to be processed through the information processing model to obtain a sixth target signal that matches the communication method of the second motor 47. The sixth data to be processed can be an adjustment instruction for controlling the rotation of the second motor 47. The communication method can be IO control communication, and the sixth target signal is sent to the second motor 47. The sixth target signal is used to control the rotation of the second motor 47 to adjust the vehicle body posture information obtained by the suspension controller 21 from the second motor 47.

[0082] Specifically, the first direction of rotation can be set to positive acceleration, and the second direction of rotation can be set to negative acceleration, wherein the first direction of rotation can be forward rotation, and the second direction of rotation can be reverse rotation; or, the first direction of rotation can be reverse rotation, and the second direction of rotation can be forward rotation. The rotation speed can be a preset speed, and the acceleration value corresponding to one rotation can be set. The acceleration sensor is connected to the second motor 47, and specifically, it can be set on the rotating shaft of the second motor 47. The rotation of the second motor 47 can drive the acceleration sensor to rotate, so that the rotation of the second motor 47 is detected by the acceleration sensor to obtain the corresponding acceleration value, and the detected acceleration value is transmitted to the suspension controller 21 through the acceleration sensor, so that the suspension controller 21 analyzes the acceleration value of each acceleration sensor to obtain vehicle body posture information. Then, when the suspension controller 21 obtains that the vehicle body posture information is the same as the target posture, the suspension controller 21 sends a control instruction, which is transmitted to the second motor 47 by the data transfer device 3 to control the second motor 47 to stop rotating, and the suspension controller 21 sends the final vehicle body posture information to the host computer 1 so that the host computer 1 can determine whether the vehicle body posture control result is accurate.

[0083] By decoupling the motor from the air spring 22 , the requirements for the motor can be reduced. The second motor 47 can rotate to simulate the vehicle body posture adjustment, thereby greatly reducing the cost and size of the motor.

[0084] In a possible implementation, the extended peripheral device 4 further includes a second relay group 48 . One acceleration sensor corresponds to one second relay group 48 .

[0085] The second relay group 48 is provided between the acceleration sensor and the suspension controller 21 and is connected to the data transfer device 3 so that the host computer 1 can transmit control instructions to the second relay group 48 through the data transfer device 3 .

[0086] When fault injection related to the second relay group 48 is required, the upper computer 1 can send a fault control instruction to the data transfer device 3. The data transfer device 3 is used to receive the to-be-processed data for the second relay group 48 sent by the upper computer 1, and process the to-be-processed data through the information processing model to obtain a target signal that matches the communication method of the second relay group 48, and send the target signal to the second relay group 48. The target signal can be used to control the on / off state of the second relay group 48 for fault injection.

[0087] Specifically, the second relay group 48 may include a fourth relay, a fifth relay, and a sixth relay, wherein the fourth relay is provided on the ground line of the acceleration sensor, the fifth relay is provided on the connection line between the acceleration sensor and the suspension controller 21, and the sixth relay is provided on the power supply line of the acceleration sensor. By controlling the fourth relay to open, a short-to-ground fault can be injected into the acceleration sensor; by controlling the fifth relay to open, an open-circuit fault can be injected into the acceleration sensor; and by controlling the sixth relay to open, a short-to-power-5 fault can be injected into the acceleration sensor. The host computer 1 can then obtain the control results of the suspension controller 21 in response to the fault in order to determine whether the control results of the suspension controller 21 in response to the fault are accurate. The fourth relay and the sixth relay are not opened at the same time.

[0088] In one possible embodiment, the suspension system 2 further includes a shock absorber, and the suspension controller 21 is connected to the shock absorber so that the suspension controller 21 can control the shock absorber accordingly. There may be multiple shock absorbers, for example, four shock absorbers, one for each of the vehicle's front left, front right, rear left, and rear right.

[0089] In one possible implementation, the expansion peripheral device 4 further includes a third relay group 49, which is disposed between the shock absorber and the suspension controller 21 and is connected to the data transfer device 3. This allows the host computer 1 to transmit control instructions to the third relay group 49 via the data transfer device 3. Each shock absorber corresponds to one third relay group 49.

[0090] When fault injection related to the third relay group 49 is required, the upper computer 1 can send a fault control instruction to the data transfer device 3. The data transfer device 3 is used to receive the pending data for the third relay group 49 sent by the upper computer 1, and process the pending data through the information processing model to obtain a target signal that matches the communication method of the third relay group 49, and send the target signal to the third relay group 49. The target signal can be used to control the on and off state of the third relay group 49 to perform fault injection.

[0091] Specifically, the third relay group 49 may include a seventh relay, an eighth relay, and a ninth relay, wherein the seventh relay is arranged on the ground line of the shock absorber, the eighth relay is arranged on the connection line between the shock absorber and the suspension controller 21, and the ninth sensor is arranged on the power supply line of the shock absorber. By controlling the seventh relay to open, a short-to-ground fault of the shock absorber can be injected; by controlling the eighth relay to open, an open-circuit fault of the shock absorber can be injected; and by controlling the ninth relay to open, a short-to-power-supply-5 fault of the shock absorber can be injected. The host computer 1 can then obtain the control result of the suspension controller 21 for the fault in order to determine whether the control result of the suspension controller 21 for the fault is accurate. The seventh relay and the ninth relay are not opened at the same time.

[0092] In one possible embodiment, the extended peripheral device 4 further includes an ammeter 410, which is disposed between the shock absorber and the suspension controller 21 and is connected to the data transfer device 3. The ammeter 410 is configured to detect the current value between the suspension controller 21 and the shock absorber and transmit the detected current value to the data transfer device 3. The data transfer device 3 may process the received current value to obtain a target signal that matches the communication method of the host computer 1, and transmit the target signal to the host computer 1 so that the host computer 1 can determine whether the suspension controller 21 accurately controls the shock absorber.

[0093] In a possible implementation, the suspension controller 21 is connected to the data transfer device 3 and the host computer 1 via the same communication main line.

[0094] The extended peripheral device 4 further includes a fourth relay group 411 , which is provided on the main communication line between the suspension controller 21 , the data transfer device 3 and the host computer 1 , and is used by the host computer 1 to control the fourth relay group 411 to be disconnected, thereby performing fault injection.

[0095] In this embodiment, when performing fault injection related to the fourth relay group 411, the upper computer 1 can control the fourth relay group 411 to disconnect, so as to perform fault injection of the disconnection of the main communication line between the suspension controller 21 and the data transfer device 3 and the upper computer 1, and then obtain the control result of the suspension controller 21, and determine whether the control result of the suspension controller 21 is accurate.

The configuration data may include data conversion relationships between multiple different communication methods, and the information processing model can be constructed based on the configuration data so that the information processing model can realize data conversion between different communication methods. The configuration data can be obtained based on the host computer obtaining the user's input data, that is, the user can directly write code on the host computer to input configuration data to the host computer; in addition, the configuration data can also be downloaded from the target platform based on the host computer.
