Description

Technical Field

[0001] This application relates to the field of intelligent driving technology, and in particular to an intelligent wiring harness detection device for automobile driving simulation equipment. Background Technology

[0002] Current automotive driving simulation wiring harness testing has the following deficiencies:

[0003] Manual inspection is inefficient: Traditional wire harness inspection uses a multimeter to measure point by point, and the inspection of a single wire harness takes more than 15 minutes, with a high error rate.

[0004] Lack of functional verification: Traditional solutions only test continuity and cannot verify key driving functions such as force feedback / CAN signals. In addition, the fixed and non-replaceable interface means that multiple models need to purchase multiple devices.

[0005] The traceability system is lacking: the test results are not recorded in a structured way, the feedback of results relies on manual observation and is prone to omissions, and the faulty wire harness cannot be associated with specific equipment batches. Utility Model Content

[0006] To address the aforementioned problems, this application provides an intelligent wiring harness inspection device for automotive driving simulators, which establishes a fully automated identification, inspection, and marking process, thus solving the problem of low efficiency in traditional wiring harness inspection devices. The technical solution is as follows:

[0007] This application provides an intelligent wiring harness testing device for automotive driving simulators, comprising a wiring harness interface board, a testing module, a printing module, and a display and broadcasting module. The wiring harness interface board is provided with an interface array and a summary connector that match the wiring harness under test. The testing module is connected to the wiring harness interface board via the summary connector and includes a wiring sequence verification circuit, a functional simulation circuit, and a result decision circuit. The printing module is connected to the output of the result decision circuit via a USB interface. The display and broadcasting module is connected to the output of the result decision circuit via a USART interface. The testing module controls the printing module to output testing labels and drives the display and broadcasting module to provide audio-visual prompts for the results.

[0008] For example, in one embodiment of the intelligent wiring harness detection device for a car driving simulation device, the wiring harness interface board is a detachable structure, and its interface array includes a steering wheel force feedback wiring harness interface, a pedal sensor wiring harness interface, and a CAN bus expansion interface.

[0009] For example, in one embodiment of the intelligent wiring harness detection device for a car driving simulation device, the wiring sequence verification circuit is connected to the interface array to measure pin continuity and impedance; the functional simulation circuit is connected to the interface array to output steering wheel torque signal, pedal travel signal, and CAN bus signal; the result decision circuit is connected to the output terminals of the wiring sequence verification circuit and the functional simulation circuit to receive the detection data from the wiring sequence verification circuit and the functional simulation circuit, and output control signals to the printing module and the display and broadcast module.

[0010] For example, in one embodiment of the intelligent wiring harness detection device for a car driving simulator, the printing module includes: a label paper roll hopper, a thermal printhead, and a cutting mechanism. The label paper roll hopper holds qualified green label / defective red label rolls; the thermal printhead has a resolution of 200 dpi; and the cutting mechanism is connected to the output end of the thermal printhead to automatically cut the labels.

[0011] For example, in one embodiment of the intelligent wiring harness detection device for a car driving simulator, the display and broadcast module integrates an LCD screen, a speaker unit, and a tri-color LED strip. The LCD screen displays the wiring harness ID, the detection item, and the detection result; the speaker unit broadcasts voice prompts; and the tri-color LED strip represents green light (qualified), red light (failed), and yellow light (in progress).

[0012] For example, in one embodiment of the intelligent wiring harness detection device for a car driving simulator, the green, red, and yellow lights of the tri-color LED strip are directly connected to the three independent drive pins of the result judgment circuit; the speaker unit has a built-in pre-stored voice chip that stores “qualified” / “unqualified” audio files.

[0013] For example, in one embodiment of the intelligent wiring harness detection device for a car driving simulator, the consolidation connector adopts an aviation plug, gold-plated pins, and a keyway structure to prevent mis-mating.

[0014] For example, in one embodiment of the intelligent wiring harness detection device for a car driving simulator, the detection module and the wiring harness interface board are connected by a rigid ribbon cable and covered with a metal shield.

[0015] The beneficial effects of the intelligent wiring harness detection device for automobile driving simulator provided in some embodiments of this application are as follows: (1) The detection efficiency is greatly improved: By integrating the wiring sequence verification circuit and the functional simulation circuit to synchronously perform continuity testing and signal injection, the detection time of a single wiring harness is reduced from 15 minutes to ≤3 minutes, which greatly improves the detection efficiency.

[0016] Zero false positive rate: Through a layered verification mechanism consisting of line sequence verification, functional simulation, and result judgment, basic continuity and disconnection detection is performed first, followed by simulated driving signal response verification, achieving a 100% fault detection rate;

[0017] Zero-cost multi-vehicle adaptation: Through the detachable interface board and modular interface array, the interface board can be replaced to adapt to 12 types of wiring harnesses, avoiding the need to replace the whole machine and reducing maintenance costs;

[0018] Zero omissions in human-computer interaction: Through the dual-channel sound and light prompts of LCD screen, speaker unit and three-color LED light strip, the visual (red light / green light) and auditory (voice) warnings are synchronized, reducing the frequency of manual intervention to zero.

[0023] This application provides an intelligent wiring harness detection device for automotive driving simulators, such as... Figure 1 As shown, the device includes a wire harness interface board, a detection module, a printing module, and a display and broadcasting module.

The printing module is connected to the output of the result decision circuit through a USB interface. The display and broadcasting module is connected to the output of the result decision circuit through a USART interface. The detection module controls the printing module to output detection tags and drives the display and broadcasting module to provide audio-visual prompts for the results.

[0024] The wiring sequence verification circuit is connected to the interface array to measure pin continuity and impedance; the function simulation circuit is connected to the interface array to output steering wheel torque signal, pedal travel signal and CAN bus signal; the result decision circuit is connected to the output terminals of the wiring sequence verification circuit and the function simulation circuit to receive the detection data of the wiring sequence verification circuit and the function simulation circuit, and output control signals to the printing module and the display and broadcast module.

[0025] According to the above embodiment, physical parameters (on / off / impedance) are measured by the wiring sequence verification circuit, driving simulation signals including torque / stroke / CAN are output by the functional simulation circuit, and control commands are generated by the result judgment circuit to drive the printing module and the display and broadcasting module.

[0033] For example, in the intelligent wiring harness detection device for automotive driving simulators provided in one embodiment, the consolidation connector adopts an aviation plug, gold-plated pins, and anti-misfit keyway structure. The gold-plated pins and anti-misfit keyway improve the connector's mating and unmating life and industrial-grade reliability, and reduce the failure rate.
