DETAILED DESCRIPTION

[0017] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0018] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0019] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0020] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0021] The traditional method of building a test bench to test vehicle controllers usually has the following disadvantages: (1) Long construction time: The construction process includes but is not limited to designing the signal source, designing the signal processing board, and designing the signal acquisition board. The construction process takes several days.

[0022] (2) Long operation time: During the vehicle controller test, the tester needs to manually turn the switches and buttons on the test bench, and the execution of a test case takes about tens of seconds.

[0023] (3) Poor reusability: The test benches used by different vehicle controllers are highly independent and cannot be shared.

[0024] In response to the above problems, an embodiment of the present application provides a vehicle controller testing device and method. With the cooperation of a host computer and a test cabinet, different test components are selected for different vehicle controllers to quickly build a corresponding test environment, and the test process is simple to operate and highly reusable.

[0025] Figure 1 This is a schematic diagram of the structure of a vehicle controller testing device provided in an embodiment of the present application. Figure 1As shown, the device may include a host computer and a test cabinet. The test cabinet is connected to the host computer on the one hand, and is connected to the vehicle controller to be tested on the other hand. Different types of signal channels are provided in the test cabinet, which are used to transmit different types of physical signals. Optionally, the physical signal may include a test signal sent by the test cabinet to the vehicle controller and a feedback signal sent by the vehicle controller to the test cabinet. For different types of vehicle controllers, the host computer is pre-configured with corresponding test components, and each test component can be used to test a vehicle controller of a certain type or a certain area in a vehicle.

[0026] Based on the types of vehicle controllers available on the market, developers can pre-set various types of test components in the host computer to cover most vehicle controllers. In actual testing, based on the type of vehicle controller, testers can add the corresponding test components to the test control interface and then perform test operations.

[0027] Optionally, different test components can be used to test vehicle controllers with different functions, or different test components can be used to test vehicle controllers that transmit different signal types. For example, based on the functions of the vehicle controllers, test component A can be used to test the wiper controller, test component B can be used to test the door lock controller, and test component C can be used to test the light controller. For another example, based on the type of transmitted signals, test component 1 can be used to test input / output (I / O) signals, and test component 2 can be used to test pulse width modulation (PWM) signals. The above-mentioned division method of the test components is only an exemplary description. In other embodiments, different test components can also be set based on other methods.

[0028] Since the test components have been pre-developed and stored in the host computer, the tester only needs to perform simple operations to build the test environment. Optionally, after the host computer displays the initial test control interface, the tester can build the test environment by dragging the test components to the test control interface. Compared with the traditional bench construction, the modular construction method based on the software level in the embodiment of the present application can effectively improve the construction speed of the test environment, thereby improving the test efficiency.

[0029] After the test environment is built, the tester can test the vehicle controller based on the test device as follows: Figure 2 As shown, specifically including: Step 201: Determine a control signal in response to a user operation.

[0030] During the vehicle controller test, the host computer displays the corresponding test control interface. The test control interface contains one or more test components. When the tester wants to test any vehicle controller, the test component can trigger the corresponding signal to start the test process. Specifically, when the host computer detects the tester's operation on any test component, it determines the control signal corresponding to the current test component.

[0031] Step 202: The host computer sends a control signal to the test cabinet.

[0032] After determining the control signal, the host computer sends the control signal to the test cabinet.

[0033] In step 203 , the test cabinet determines a test signal associated with the control signal and sends the test signal to the vehicle controller.

[0034] The control signal is an electrical signal, which is transmitted between the host computer and the test cabinet. The test cabinet is provided with multiple signal channels, which are used to send actual physical signals to the vehicle controller and receive physical signals fed back by the vehicle controller. Specifically, after receiving the control signal sent by the host computer, the test cabinet determines the test signal associated with the control signal, which is a physical signal, and is transmitted to the vehicle controller through the signal channel of the test cabinet.

[0035] Step 204: perform corresponding operations based on the test signal.

[0036] The test signal can be regarded as various signals that may be received during the driving of the vehicle. For example, the test signal may include a light signal, a door lock signal, and a wiper washing signal. After receiving the test signal, the vehicle controller controls the vehicle to perform corresponding operations.

[0037] Step 205: The vehicle controller sends a corresponding feedback signal to the test cabinet.

[0038] The feedback signal can be used to indicate whether the current vehicle controller can normally perform corresponding operations according to the test signal.

[0039] Step 206: The test cabinet determines an indication signal associated with the feedback signal, and sends the indication signal to the host computer.

[0040] When the test cabinet receives the feedback signal through the signal channel, it determines the corresponding indication signal and sends the indication signal to the host computer.

[0041] Step 207: The host computer displays the indication signal on the test control interface.

[0042] After receiving the indication signal, the host computer displays the indication signal on the test control interface.

[0043] In an optional embodiment, the test control interface displayed by the host computer can be as follows: Figure 3 As shown, it includes: power supply test component, wiper and washing test component, lighting test component and door lock test component. Most test components such as wiper and washing test component, lighting test component and door lock test component include control area and test area. The control area includes one or more control buttons, each of which corresponds to a control signal. When the user clicks any control button, the host computer can send the corresponding control signal to the test cabinet. The feedback area includes one or more feedback indicator lights, each of which corresponds to an indication signal. When the host computer receives the indication signal sent by the test cabinet, it will change the display state of the corresponding feedback indicator light. For example, the feedback indicator light is off by default. When the indication signal is received, the host computer adjusts the feedback indicator light to a constant light state. For another example, the feedback indicator light is white by default. When the indication signal is received, the host computer adjusts the feedback indicator light to red. The display state of the feedback indicator light is not limited and can be flexibly set by the tester.

[0044] Reference Figure 4 When the tester wants to test the vehicle's light controller, he can click the control button in the light test component to execute the test process. The position indicated by arrow 401 is the control button of the headlight switch. When the tester clicks the control button, the host computer changes the display state of the control button, indicating that the current test has started. If the vehicle's headlights can be turned on normally, the host computer will receive the indication signal sent by the test cabinet. After receiving the indication signal, the host computer changes the display state of the headlights.

[0045] Compared with manually turning switches and buttons on the test bench, after applying the above test device, the tester only needs to operate the test components in the test control interface of the host computer, and the physical signal is sent by the test cabinet. This test method reduces the amount of operations and the difficulty of operation in the test process, and shortens the test time. In addition, when the tester wants to test another batch of vehicle controllers, he only needs to delete the original test components in the test control interface and re-add other test components. By adjusting the test components at the software level, the test environment can be adjusted efficiently, and the reusability is strong.

[0046] Figure 5 A flow chart of another vehicle controller testing method provided in an embodiment of the present application. Figure 5 As shown, the method may include: Step 501, determine the signal type and signal direction of the vehicle controller under test.

[0047] Before testing, the tester sorts out the signal types (such as I / O signals, PWM signals, resistance switch signals) and signal directions (such as input signals, output signals) of the vehicle controller under test.

[0048] Step 502: Select a corresponding signal channel in the test cabinet.

[0049] The test cabinet is pre-set with multiple signal channels, corresponding to different signal types and / or signal directions. The tester needs to select the signal channel associated with the current signal type and signal direction.

[0050] Step 503: adjust the test model according to the signal channel.

[0051] The tester adjusts the test model at the software level. Optionally, the test software in the host computer can be developed and implemented by MATLAB.

[0052] Step 504: construct a test control interface.

[0053] Testers add test components to the test control interface by dragging and dropping test components, thereby quickly building the test control interface.

[0054] Step 505, perform the test.

[0055] The tester operates the vehicle controller by operating in the test control interface. The specific test process can refer to the description of the above embodiment.

Figure 6 As shown, the method may include: Step 601: The test cabinet receives the feedback signal sent by the vehicle controller and sends an indication signal associated with the feedback signal to the host computer. The test cabinet is provided with a plurality of signal channels, each of which is used to transmit a corresponding type of feedback signal.

[0057] Step 602, when the host computer receives the indication signal sent by the test cabinet, the indication signal is displayed on the test control interface, and the test control interface includes multiple test components, each test component is used to test at least one vehicle controller.

[0058] In an optional embodiment, after the test starts, in response to a test request triggered by a user based on any test component, the host computer sends a corresponding control signal to the test cabinet. When the test cabinet receives the control signal, it sends a test signal associated with the control signal to the vehicle controller through a corresponding signal channel.

[0061] (2) Short test bench operation time: After the host computer developer develops the test components and the initial test control interface, the tester can complete the test by simply clicking the corresponding test component with the mouse.
