Description

Technical Field

[0001] This invention relates to a functional testing platform and method for integrated AMT (Automated Manual Transmission) controllers, specifically to a functional testing platform and method applicable to multiple types of integrated AMT controllers. Background Technology

[0002] As the key "human-machine interaction hub" of the AMT system, the integrated AMT handle has become much more complex. It not only needs to perform precise gear selection, but also integrates function buttons such as cruise control, shift strategy selection, and slope adaptation. It needs to handle a large number of high-precision CAN inputs and outputs, and its development quality is directly tied to the overall vehicle performance experience and system reliability.

[0003] Currently, functional testing of integrated AMT (Automated Manual Transmission) handles primarily relies on vehicle road testing or mechanical static bench testing. However, vehicle road testing is time-consuming, costly, has limited operational coverage, and struggles to reproduce specific extreme scenarios. Meanwhile, mechanical static bench testing typically only verifies the connectivity of simple control signals, failing to meet the in-depth verification needs for dynamic driving scenarios, signal coupling logic, and communication protocol consistency. These issues can lead to design flaws only becoming apparent after mass production, resulting in significant commercial and brand risks and becoming a critical weakness in the development process of integrated AMT handles.

[0004] Furthermore, due to differences in functionality, button layout, and triggering methods among different types of integrated AMT handles, the industry lacks a HIL controlled object model that can simultaneously meet the functional testing requirements of many types of integrated AMT handles. Currently, integrated AMT handle functional testing typically uses a single HIL controlled object model matched to a specific type of integrated AMT handle and gearbox, as illustrated in Chinese patent publication number CN109031977A. This approach easily leads to frequent switching of the HIL controlled object model when testing different types of integrated AMT handles and their corresponding TCU functions, wasting testing time and increasing the workload on the host computer. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problem that existing integrated AMT handle functional testing platforms are only designed for specific types of integrated AMT handles and corresponding TCUs, resulting in low testing efficiency and high load on the host computer. The invention provides a functional testing platform and testing method applicable to multiple types of integrated AMT handles.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A functional testing platform applicable to multiple types of integrated AMT handles is characterized by including a handle type selection switch, a button status recognition module, multiple handle type modules, a handle signal distribution module, a CAN configuration module, and a HIL cabinet.

[0008] The output of the handle type selection switch is connected to the first input of the button status recognition module and the first input of the handle signal distribution module, respectively. The handle type selection switch is used to switch between multiple types of integrated AMT handles and outputs the handle identifier of the current handle type.

[0009] The second input terminal of the button state recognition module is used to connect to the integrated AMT handle under test, and the output terminal is connected to the input terminals of multiple handle type modules respectively. The button state recognition module is used to determine the initial state of the function buttons on the integrated AMT handle under test according to the handle identifier, and to identify its current state to obtain the button request signal.

[0010] Each of the aforementioned handle type modules corresponds to a type of integrated AMT handle. The output terminal of the handle type module is connected to the second input terminal of the handle signal distribution module, which is used to convert the button request signal into a request message.

[0011] The output of the handle signal distribution module is connected to the input of the CAN configuration module. The handle signal distribution module is used to select the corresponding request message according to the handle identifier and obtain the TC1 receive message.

[0012] The output of the CAN configuration module is connected to the input of the HIL cabinet. The CAN configuration module is used to configure the TC1 receiving address for TC1 receiving messages.

[0013] The output terminal of the HIL cabinet is used to connect to the input terminal of the corresponding TCU of the integrated AMT handle under test. The HIL cabinet is used to condition the TC1 received messages.

[0014] Furthermore, the handle type module includes a gear request unit, a Mode1 function unit, a Mode2 function unit, a Mode3 function unit, a Mode4 function unit, and a Mode5 function unit;

[0015] The input terminals of the gear position request unit, Mode1 function unit, Mode2 function unit, Mode3 function unit, Mode4 function unit, and Mode5 function unit are respectively connected to the output terminal of the button status recognition module, and the output terminals are respectively connected to the second input terminal of the handle signal distribution module. The gear position request unit, Mode1 function unit, Mode2 function unit, Mode3 function unit, Mode4 function unit, and Mode5 function unit are used to convert the button request signal into a request message.

[0016] This invention also provides a functional testing method applicable to multiple types of integrated AMT controllers, using the aforementioned functional testing platform applicable to multiple types of integrated AMT controllers. Its unique feature is that it includes the following steps:

[0017] Step 1: Set the handle identifier for the multi-type integrated AMT handle and input the handle type selection switch; obtain the TC1 message receiving address of the multi-type integrated AMT handle, get multiple TC1 message receiving addresses and input them into the CAN configuration module;

[0018] Step 2: Obtain the union of TC1 message signals of multiple types of integrated AMT handsets in DBC, and perform unified processing to obtain multiple function signals and their requests; then, uniformly set the function keys corresponding to each request in all function signals; after configuring multiple function signals and their requests according to the functions and function keys of each type of integrated AMT handset, input them into the corresponding handset type module.

[0019] Step 3: Based on the type of the integrated AMT controller to be tested, select the corresponding controller identifier in the controller type selection switch. The controller type selection switch will transmit the controller identifier to the button status recognition module and the controller signal distribution module respectively.

[0020] Step 4: Connect the integrated AMT handle to be tested to the button status recognition module, and connect the corresponding TCU of the integrated AMT handle to be tested to the HIL cabinet; the button status recognition module determines the initial state of the function buttons on the integrated AMT handle to be tested according to the handle identifier, obtains the button request signal, and transmits it to the corresponding handle type module of the integrated AMT handle to be tested.

[0021] Step 5: The controller type module converts the button request signal into a request message and transmits it to the controller signal distribution module based on the various function signals and requests configured in Step 2. The controller signal distribution module selects the request message corresponding to the integrated AMT controller under test as the TC1 receive message based on the controller identifier and transmits it to the CAN configuration module.

[0022] Step 6: The CAN configuration module configures multiple TC1 message receiving addresses for the TC1 received messages and transmits them to the HIL cabinet for conditioning, and then transmits them to the TCU; the TCU reads and parses the TC1 received messages according to the TC1 message receiving address corresponding to the integrated AMT handle under test, and then triggers the corresponding request.

[0023] Step 7: Check whether the TCU-triggered request is correct and whether the response time meets the design requirements. Then, press a function button on the integrated AMT handle under test. The button status recognition module identifies the current status of the function button on the integrated AMT handle under test, obtains the control signal, and transmits it as a button request signal to the corresponding handle type module of the integrated AMT handle under test. Return to step 5 until all the function buttons under test on the integrated AMT handle under test are traversed. Then, execute step 8.

[0024] Step 8: Determine if there are different types of integrated AMT controllers to be tested that have not undergone functional testing. If so, return to step 3 and perform functional testing on the next type of integrated AMT controller to be tested; otherwise, complete the functional testing of the integrated AMT controller.

[0025] Furthermore, in step 2, the specific method for configuring the various functional signals and their requests is as follows:

[0026] If the integrated AMT handle has all the functions corresponding to the function signals, then configure the corresponding function signals according to the functions of the integrated AMT handle; if the integrated AMT handle lacks a certain function, then configure the function signal corresponding to that function to ground.

[0027] If the integrated AMT controller has function buttons corresponding to all requests in the function signals, then configure the corresponding requests in the function signals according to the function buttons of the integrated AMT controller; if the function buttons of the integrated AMT controller lack a certain request in the function signals, then configure that request as No Command.

[0028] Furthermore, in step 2, the specific method for performing the standardization process is as follows:

[0029] The union of TC1 message signals of various types of integrated AMT handles in DBC is classified according to function to obtain various functional signals and the requests contained therein, and then the functional signals are uniformly named.

[0030] Furthermore, in step 2, there are 6 types of functional signals: gear position request signal, Mode1 signal, Mode2 signal, Mode3 signal, Mode4 signal, and Mode5 signal. Among them, the gear position request signal has 11 types of requests: D, M, N, R, RM, DM, upshift, downshift, No command, Error, and Not Available. The Mode1, Mode2, Mode3, Mode4, and Mode5 signals each have 4 types of requests.

[0031] Furthermore, in step 2, the specific method for uniformly naming the functional signals is as follows:

[0032] According to the SAE 1939 specification, the gear request signal, Mode1 signal, Mode2 signal, Mode3 signal, Mode4 signal and Mode5 signal are named TransRequestedGear, TransMode1, TransMode2, TransMode3, TransMode4 and TransMode5 respectively.

[0033] Furthermore, in step 2, the specific method for uniformly setting the function keys corresponding to each request in all function signals is as follows:

[0034] Set the function keys corresponding to the gear request signals D, M, N, R, RM, DM, upshift, downshift, No command, Error, and Not Available to 1-11 respectively;

[0035] Set the function keys corresponding to the requests in Mode1, Mode2, Mode3, Mode4, and Mode5 signals to 1-4 respectively.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] This invention provides a functional testing platform and method applicable to multiple types of integrated AMT handles. By standardizing the TC1 message signals of different types of integrated AMT handles, the handle type modules corresponding to different types of integrated AMT handles have the same input and output signals. This eliminates the need to switch the HIL controlled object model during functional testing of different types of integrated AMT handles, improving testing efficiency and reducing the workload of the host computer. Furthermore, the modular approach to building the handle type modules ensures that each module is independent, with signals that do not interfere with each other. The output signal is controlled by a handle type selection switch, ensuring uniqueness and facilitating handle type switching during testing. Attached Figure Description

[0040] Figure 3 This is a schematic diagram of the wire harness connection in actual application of the embodiments of the present invention. Detailed Implementation

[0041] The functional testing platform and testing method applicable to multiple types of integrated AMT handheld devices proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of this invention and are not intended to limit the scope of protection of this invention.

[0042] A functional testing platform applicable to multiple types of integrated AMT handles, such as Figure 1 As shown, it includes a handle type selection switch, a button status recognition module, multiple handle type modules, a handle signal distribution module, a CAN configuration module, and a HIL cabinet.

[0043] The output of the handle type selection switch is connected to the first input of the button status recognition module and the first input of the handle signal distribution module, respectively. The handle type selection switch is used to switch between multiple types of integrated AMT handles and outputs the handle identifier of the current handle type. The second input of the button status recognition module is connected to the integrated AMT handle under test, and its output is connected to the input of multiple handle type modules, respectively. The button status recognition module is used to determine the initial state of the function buttons on the integrated AMT handle under test based on the handle identifier, identify its current state, and obtain a button request signal.

[0044] Each handle type module corresponds to a type of integrated AMT handle. The output of the handle type module is connected to the second input of the handle signal distribution module, used to convert button request signals into request messages. The handle type module includes a gear position request unit, Mode1 functional unit, Mode2 functional unit, Mode3 functional unit, Mode4 functional unit, and Mode5 functional unit. The inputs of these units are connected to the output of the button status recognition module, and their outputs are connected to the second input of the handle signal distribution module. These units are used to convert button request signals into corresponding request messages.

[0045] The output of the handle signal distribution module is connected to the input of the CAN configuration module. The handle signal distribution module is used to select the corresponding request message based on the handle identifier to obtain the TC1 receive message. The output of the CAN configuration module is connected to the input of the HIL cabinet. The CAN configuration module is used to configure the TC1 receive address for the TC1 receive message. The output of the HIL cabinet is used to connect to the input of the corresponding TCU of the integrated AMT handle under test. The HIL cabinet is used to condition the TC1 receive message.

[0046] This embodiment also provides a functional testing method applicable to multiple types of integrated AMT controllers, using the aforementioned functional testing platform applicable to multiple types of integrated AMT controllers, such as... Figure 2 As shown, it includes the following steps:

[0047] Step 1: Set the handle identifier for the multi-type integrated AMT handle and input the handle type selection switch; obtain the TC1 message receiving address for the multi-type integrated AMT handle, obtain multiple TC1 message receiving addresses and input them into the CAN configuration module.

[0048] Based on differences in function, button layout, and triggering method, there are currently 10 types of integrated AMT handles for heavy-duty trucks. In this embodiment, the handle identifiers for the 10 types of integrated AMT handles are set to values ​​from 0 to 9, with each value representing a type of integrated AMT handle. The 10 types of integrated AMT handles share a total of 3 TC1 message receiving addresses.

[0049] Step 2: Obtain the union of TC1 message signals from multiple types of integrated AMT handles in the DBC (CAN database file), and perform unified processing to obtain various functional signals and their requests. Then, uniformly set the function buttons of the integrated AMT handles corresponding to each request in all functional signals. After configuring the various functional signals and their requests according to the functions and function buttons of each type of integrated AMT handle, input them into the corresponding handle type module. The specific method for unified processing is as follows: classify the union of TC1 message signals from multiple types of integrated AMT handles in the DBC according to function to obtain various functional signals and their contained requests, and then uniformly name the functional signals.

[0050] In this embodiment, the functions involved in the 10 integrated AMT handles are divided into static and dynamic functions. The static functions include starting and shifting into DM (forward creep), RM (reverse creep), R (reverse), N (neutral), OffRoad (off-road mode), E (economy mode), P (power mode), A (automatic mode), and M (manual mode). The dynamic functions include: A / M mode switching, E / P mode switching, gear self-learning, slope self-learning, switching between different gear modes (e.g., shifting during M mode driving), and shifting up or down a gear during driving.

[0051] The following differences exist in the definitions of TC1 messages and function signals for different types of integrated AMT handles: 1) Different TC1 message receiving addresses; 2) Inconsistent number of TC1 message signals; 3) Different functions corresponding to the same function signal; 4) Different triggering methods for the same function signal; 5) Different triggering methods for different gear requests; 6) Different initial state values ​​for the same signal. In this embodiment, the above 10 types of integrated AMT handles are combined according to the definition of TC1 message signals to obtain 6 function signals, including gear request signal, Mode1 signal, Mode2 signal, Mode3 signal, Mode4 signal, and Mode5 signal. The gear request signal contains 11 types of requests: D, M, N, R, RM, DM, increase gear, decrease gear, No command, Error, and Not Available. The Mode1, Mode2, Mode3, Mode4, and Mode5 signals each contain 4 types of requests. Then, following the SAE 1939 standard, the gear request signal, Mode1 signal, Mode2 signal, Mode3 signal, Mode4 signal, and Mode5 signal are named TransRequestedGear, TransMode1, TransMode2, TransMode3, TransMode4, and TransMode5, respectively. Simultaneously, the function keys corresponding to the integrated AMT handles requested in the function signals are uniformly configured: the function keys for requesting D, M, N, R, RM, DM, upshift, downshift, No command, Error, and Not Available in the gear request signal are set to 1-11 respectively; the requests in the Mode1, Mode2, Mode3, Mode4, and Mode5 signals are set to 1-4 respectively.

[0052] In step 2, the specific method for configuring various function signals and their requests is as follows: If the integrated AMT handle has the functions corresponding to all function signals, then configure the corresponding function signals according to the functions of the integrated AMT handle; if the integrated AMT handle lacks a certain function, then configure the function signal corresponding to that function as grounded. If the integrated AMT handle has function buttons corresponding to all requests in the function signals, then configure the corresponding requests in the function signals according to the function buttons of the integrated AMT handle; if the function buttons of the integrated AMT handle lack a certain request in the function signals, then configure that request as No Command.

[0053] Specifically, if a certain type of integrated AMT controller does not have a Mode5 function, the TransMode5 signal is grounded. If a certain type of integrated AMT controller has fewer than 11 TransRequestedGear requests, it is still configured to have 11 gear requests to ensure consistent output signals, with unused gear requests set to No command. If a certain type of integrated AMT controller does not have an RM request, RM is set to No command. If the pressed function button is 2, the gear request unit outputs M gear as the received value of the TransRequestedGear signal in the TC1 message.

[0054] Step 3: Based on the type of the integrated AMT controller to be tested, select the corresponding controller identifier in the controller type selection switch. The controller type selection switch will then transmit the controller identifier to the button status recognition module and the controller signal distribution module respectively.

[0055] Step 4: Connect the integrated AMT handle to be tested to the button status recognition module, and connect the corresponding TCU of the integrated AMT handle to be tested to the HIL cabinet; the button status recognition module determines the initial state of the function buttons on the integrated AMT handle to be tested according to the handle identifier, obtains the button request signal, and transmits it to the corresponding handle type module of the integrated AMT handle to be tested.

[0056] Step 5: The handle type module converts the button request signal into a request message and transmits it to the handle signal distribution module according to the function and function button configured in Step 2. The handle signal distribution module selects the request message corresponding to the integrated AMT handle under test as the TC1 receive message according to the handle identifier and transmits it to the CAN configuration module.

[0057] The gear request unit, Mode1 function unit, Mode2 function unit, Mode3 function unit, Mode4 function unit and Mode5 function unit in the handle type module are triggered according to the button request signal corresponding to the corresponding function button on the integrated AMT handle under test, and output the signal output values ​​of TransRequestedGear, TransMode1, TransMode2, TransMode3, TransMode4 and TransMode5 respectively to obtain the request message.

[0058] Step 6: The CAN configuration module configures multiple TC1 message receiving addresses for the TC1 received messages and transmits them to the HIL cabinet for conditioning, and then transmits them to the TCU; the TCU reads and parses the TC1 received messages according to the TC1 message receiving address corresponding to the integrated AMT handle under test, and then triggers the corresponding request.

[0059] The CAN configuration module is configured with TC1 receive messages for three different addresses. However, the TCU will only enable the TC1 receive messages for the TC1 receive address corresponding to the integrated AMT handle under test; the other two TC1 receive addresses will be masked. Therefore, although the CAN bus in the HIL cabinet can detect TC1 receive messages for all three TC1 receive addresses, it does not affect the implementation of the software functions.

[0060] Step 7: Check if the TCU-triggered request is correct and if the response time meets the design requirements. Then, press a function button on the integrated AMT handle under test. The button status recognition module identifies the current status of the function button on the integrated AMT handle under test, obtains the control signal, and transmits it as a button request signal to the corresponding handle type module of the integrated AMT handle under test. Return to step 5 until all the function buttons under test on the integrated AMT handle under test are traversed. Then, execute step 8.

[0061] Step 8: Determine if there are different types of integrated AMT controllers to be tested that have not undergone functional testing. If so, return to step 3 and perform functional testing on the next type of integrated AMT controller to be tested; otherwise, complete the functional testing of the integrated AMT controller.

[0062] In practical applications, the controller type selection switch, button status recognition module, multiple controller type module, controller signal distribution module, and CAN configuration module of this embodiment are built in the host computer. The specific building process is as follows:

[0063] 1) After unifying the TC1 message signal in DBC in step 2, load DBC into the RTICAN configuration, compile RTICAN, and define the TC1 message input interface.

[0064] 2) Add the handle type module to the vehicle physical model (Simulink, i.e., HIL controlled object model) and connect the handle type module to the TC1 message input interface;

[0065] 3) Compile the handle type selection switch, button status recognition module, handle signal distribution module and CAN configuration module in this embodiment in the ConfigurationDesk software installed on the host computer, and generate an sdf file;

[0066] 4) Add the .sdf file to the ControlDesk software installed on the host computer to create the human-machine interface for the gamepad.

[0067] Using CANape to monitor TC1 received messages and controller function metrics in real time, after the functional test platform applicable to multiple types of integrated AMT controllers provided in this embodiment is built, it is then conducted according to... Figure 3 The wiring harnesses of the TCU, CANape, and HIL cabinets are connected as shown. Then, the ControlDesk experimental management engineering software is run on the host computer. The physical model of the whole vehicle is connected through the RTI real-time simulation interface. The button status recognition module is controlled on the human-machine interface of the handle to verify the function of the handle model and the function of the software handle.

[0068] Taking a gamepad that is statically engaged in M ​​gear for starting and dynamically performs upshifting and downshifting operations as an example, the specific steps for functional testing are as follows:

[0069] 1) Select the controller type in the controller HMI interface in ControlDesk;

[0070] 2) Monitor in CANape whether the TC1 receive message corresponding to this handle is received by the TCU;

[0071] 3) In CANape, monitor whether the initial state of the function buttons on the controller is correct;

[0072] 4) In the controller HMI interface in ControlDesk, press the brake pedal, press the controller gear request button to shift to M gear, check if the TCU is engaged in M ​​starting gear, and check if the response time meets the requirements.

[0073] 5) Release the brake pedal, press the accelerator, and wait for the engine speed to rise to the upshift point. Then, press the shift request button on the lever to shift up one gear. Check if the TCU upshift request is triggered and check if the response time meets the requirements.

[0074] 6) Similarly, release the accelerator and wait for the engine speed to drop to the downshift point. Then, press the shift lever to request downshifting. Check if the TCU downshift request is triggered and check if the response time meets the requirements.

[0075] 7) Press the handle gear request button to shift to N gear, check if the TCU returns to neutral, and check if the response time meets the requirements.

[0076] In this embodiment, the button state recognition module is the button input terminal of the integrated AMT controller under test. Based on the number of function signals for various types of integrated AMT controllers, each function signal corresponds to a constant module. When different values ​​are input to each constant module, the controller type module outputs request messages for different functions. For example, if the current controller type selection switch is 0, according to the TC1 message signal definition for this type of integrated AMT controller, when the button corresponding to the Mode1 signal is pressed, the Mode1 function unit in the controller type module will be triggered, outputting a request message. For example, if the current controller type selection switch is 0, according to the TC1 message signal definition for this type of integrated AMT controller, the initial state of TransRequestedGear is X1, the initial state of TransMode1 is X2, the initial state of TransMode2 is X3, the initial state of TransMode3 is X4, the initial state of TransMode4 is X5, and there is no TransMode5 function. Any value can be assigned, which avoids TCU malfunctions caused by different types of integrated AMT controllers having the same initial signal value.

[0077] This embodiment uses a modular approach to build the handle type modules. By designing an independent handle type module for each type of integrated AMT handle, the 10 handle type modules have the same named input and output signals. There are 6 input signals, which are 6 function signals, and their source is the function key status output by the key status recognition module. The output signal is the request message obtained after the function key status is processed by the handle type module. After the request message is processed by the handle signal distribution module, it is input to the TC1 message module at the corresponding address. After being conditioned by the CAN board in the HIL cabinet, the request message is finally received by the TCU.

[0078] The functional testing platform and method provided in this embodiment, applicable to multiple types of integrated AMT handles, ensures that each handle type module is independent and their signals do not interfere with each other. The output signal is controlled by a handle type selection switch, ensuring the uniqueness of the handle. It also facilitates handling type switching during testing, effectively replacing extensive and costly real-vehicle road testing, reducing reliance on the number of prototype vehicles and mileage, and avoiding resource waste caused by rework due to misjudgments, thus lowering R&D costs. If new handle types, TC1 message signals, or TC1 message receiving addresses are added subsequently, only the new handle type module and the corresponding signals need to be added.
