[0071] In an exemplary embodiment provided by the present disclosure, the detection module 100 includes an input anomaly detection unit;

[0072] The input abnormality detection unit is configured to be connected to the display module 200 and the signal acquisition module 300, and the input abnormality detection unit stores a first instruction;

[0073] The input abnormality detection unit is used to execute a first instruction when an input signal is acquired, and perform input abnormality detection on an input hardware circuit based on the input signal when the first instruction is executed.

[0074] By storing the first instruction in the input anomaly detection unit, the first instruction can be automatically executed when the input anomaly detection unit obtains an input signal, so as to complete the input anomaly detection of the input hardware circuit, which is more convenient.

[0075] In an exemplary embodiment provided by the present disclosure, the input anomaly detection unit is configured to:

[0076] When the first instruction is executed, determining whether a preset electrical quantity of the input signal reaches a preset threshold;

[0077] When the preset electrical quantity reaches a preset threshold, the input signal is determined to be normal, and an input abnormality detection result indicating that the input hardware circuit is normal is output; or,

[0078] When the preset electrical quantity does not reach the preset threshold, it is determined that the input signal is abnormal, and an input abnormality detection result representing the abnormality of the input hardware circuit is output.

[0079] By judging whether the current or voltage value of the input signal reaches the preset threshold, it is possible to determine whether the input signal can trigger the corresponding action hardware, and then determine whether the input signal is abnormal. This judgment method is simple and effective, and the testing difficulty is low.

[0080] In an exemplary embodiment provided by the present disclosure, the detection module 100 includes an output abnormality detection unit;

[0081] The output abnormality detection unit is configured to be connected to the display module 200 and the signal output module 400, and the output abnormality detection unit stores a second instruction;

[0082] The output abnormality detection unit is used to send a preset output signal to the second test end 600 through the signal output module 400 and the second preset wiring harness in sequence when the second instruction is executed, so as to determine the output abnormality detection result of the output hardware circuit according to the operation state of the second test end 600.

[0083] By using the second instruction in the output abnormality detection unit, a preset output signal can be sent to the second test end 600 through multiple second preset wiring harnesses, and then the output abnormality detection result of the second preset wiring harness or the second test end 600 can be determined according to the action status of each second test end 600.

[0084] In an exemplary embodiment provided by the present disclosure, please refer to Figure 2 As shown, the system further includes a signal forwarding module 700;

[0085] The signal forwarding module 700 is configured to be in communication with the signal acquisition module 300 and the detection module 100;

[0086] The signal forwarding module 700 is used to obtain the input signal obtained by the signal obtaining module 300 and send the input signal to the detection module 100 .

[0087] Through the above configuration, the detection module 100 and the modules actually connected to the hardware can be separated to facilitate detection and improve detection efficiency.

[0088] In this embodiment, the above-mentioned signal forwarding module 700 can be a vehicle control unit (VCU). In this case, the detection module 100 and the display module 200 can be integrated into a host computer, and the communication method between the signal forwarding module 700 and the detection module 100 can be CAN communication.

[0089] In an exemplary embodiment provided by the present disclosure, the signal forwarding module 700 includes a digital-to-analog conversion unit;

[0090] The digital-to-analog conversion unit is configured to communicate with the signal acquisition module 300 to acquire an input signal and, if the input signal is an analog signal, perform signal conversion on the input signal to obtain a digital input signal corresponding to the input signal.

[0091] By setting up the digital-to-analog conversion unit, the input signal, which is an analog signal, can be converted into a digital signal, so as to facilitate the judgment of whether the electrical quantity of the input signal reaches the preset threshold, thereby greatly reducing the difficulty of judging whether the input signal is abnormal.

[0092] In an exemplary embodiment provided by the present disclosure, the signal forwarding module 700 further includes a communication unit;

[0093] The communication unit is configured to be communicatively connected to the digital-to-analog conversion unit and the detection module 100 respectively, so as to send the digital input signal to the detection module 100;

[0094] The communication unit is further configured to be in communication connection with the signal output module 400 , and the detection module 100 is used to send a preset output signal to the second test end 600 through the communication unit, the signal output module 400 and the second preset wiring harness in sequence.

[0095] In an exemplary embodiment provided by the present disclosure, the first test end 500 includes: at least one of an accelerator pedal, a brake pedal, a turn signal lever, a horn button, a gear switch, and an emergency stop button;

[0096] The second test end 600 includes at least one of a driving motor controller, a brake, a turn signal, a horn, and a gear.

[0097] When an abnormality detection of an input hardware circuit is required, the present disclosure uses the first test end 500 as an accelerator pedal for schematic illustration:

[0098] The sliding rheostat in the accelerator pedal is connected to one end of the first preset wiring harness, and the other end of the first preset wiring harness is connected to the signal acquisition module 300. Then, by pressing the accelerator pedal, the input signal current value input to the first preset wiring harness is simulated in the real environment, and the input signal is converted into a digital signal for convenient judgment of the abnormality size through the digital-to-analog conversion unit. In this embodiment, the digital signal is expressed in the form of a voltage value, and it is transmitted to the input abnormality detection unit through the communication unit. As the first instruction in the input abnormality detection unit runs, it is determined whether the above-mentioned voltage value reaches the preset threshold. If the voltage value reaches the threshold, it is determined that there is no abnormality in the first preset wiring harness and the first test end 500 detected this time, and the input abnormality detection result indicating that the input hardware circuit is normal is output; if the voltage value is less than the threshold, it is determined that there is an abnormality in the first preset wiring harness and the first test end 500 detected this time, and the input abnormality detection result indicating that the input hardware circuit is abnormal is output.

[0099] After determining the input abnormality detection result, the input abnormality detection result is displayed in a preset display method through the display module 200, and the display method can be through, for example, a CRT (cathode ray tube) or an LCD (liquid crystal display), or through other auditory or tactile notifications or perceptions.

[0100] Similarly, the first test terminal 500 can also be at least one of the vehicle hardware switches, such as a brake pedal, turn signal lever, horn button, and gear switch. When the first test terminal 500 is a vehicle hardware switch, the corresponding hardware switch is similarly connected to the signal acquisition module 300 via the first preset wiring harness. The input abnormality detection result is then observed on the display module 200 to determine the abnormality of the input hardware circuit formed by the first preset wiring harness and the first test terminal 500.

[0101] It should be understood that the above-mentioned signal acquisition module 300 can simultaneously connect multiple first preset wiring harnesses and connect multiple first test ends 500 through each first preset wiring harness, and then simultaneously detect multiple input hardware circuits composed of multiple first test ends 500 and multiple first preset wiring harnesses, and present the final detection results in the display module 200, which is highly efficient, has low testing difficulty, and is convenient and simple to operate.

[0102] When it is necessary to detect an abnormality of the output hardware circuit, the following is a schematic description using the second test end 600 as a turn signal as an example:

[0103] Connect the turn signal to one end of the second preset wiring harness, and connect the other end of the second preset wiring harness to the signal output module 400. Then, the output abnormality detection unit runs the second instruction to issue a preset output signal for the turn signal. The preset output signal passes through the communication unit, the signal output module 400 and the second preset wiring harness in sequence to reach the second test end 600. At this time, since the second test end 600 will feedback an operating status result and feedback it to the output abnormality detection unit through the signal output module 400 and the communication unit, at this time, the display module 200 can take the above-mentioned operating status result as the output abnormality detection result, and use the output abnormality detection result to visually present whether the second preset wiring harness and the second test end 600 detected this time are abnormal.

[0104] It should be noted that due to the voltage drop in the second preset wiring harness, the voltage value of the above-mentioned preset output signal needs to be schematically increased according to the voltage drop. At the same time, the preset output signal has two types: high-side drive output and low-side drive output, and is adjusted accordingly according to the different types of the second test end 600. For example, when the second test end 600 needs to use a delay relay, the preset output signal is controlled to be a high-side drive output. If a delay relay is not required, the preset output signal is controlled to be a low-side drive output.

[0105] Of course, you can also manually observe the operating status of the corresponding second test end 600, such as whether the turn signal is turned on correctly, whether the horn sounds normally, etc., to determine whether the output hardware circuit composed of the corresponding second test end 600 and the second preset wiring harness is abnormal.

[0106] In summary, the present disclosure has the following beneficial effects:

[0107] 1. Hardware and wiring harness diversity detection can efficiently troubleshoot abnormal problems in the hardware circuits composed of the vehicle wiring harness and hardware devices.

[0108] Second, multiple sets of wiring harnesses and hardware equipment can be tested at the same time, with high efficiency, low testing difficulty and simple operation.

[0109] 3. The detection module 100 detects the input voltage value of the input signal obtained by the first test terminal 500 to detect the abnormal state of the hardware circuit composed of the hardware and the wiring harness.

[0110] 4. Verify the abnormal state of the hardware circuit composed of the wiring harness and hardware devices by detecting the voltage value of the preset output signal output by the detection module 100.

[0111] Because this device and solution offer high accuracy and low difficulty, they are suitable for testing in a variety of scenarios, including early production, assembly, vehicle wiring harness verification, and after-sales troubleshooting. Simultaneously verifying and testing multiple wiring harnesses and hardware devices reduces testing costs while improving efficiency.
