Description

TECHNICAL FIELD

[0001] The present application belongs to the field of automobile simulation technology, and particularly relates to a vehicle module identification error fault type setting system and method. BACKGROUND

[0002] With the rapid development of the intelligent and networked vehicle market, there is a serious shortage of skilled personnel in the intelligent and networked vehicle industry. Vocational colleges, as the cradle of cultivating technical personnel, shoulder the heavy responsibility of cultivating high-quality and high-skilled intelligent and networked vehicle professionals. According to the demand for talent training in vocational colleges, we independently designed and developed a fault setting box and a practical measurement platform for the intelligent and networked vehicle equipment.

[0003] The continuous addition of functions of intelligent and networked vehicles leads to the continuous increase of sensors and modules, and the supporting wire harness also increases in a geometric manner. In order to reduce the wire harness and enable modular production of modules, more and more modules with hard-wired ID cards and modular design are used on intelligent and networked vehicles.

[0004] The fault setting box is an auxiliary teaching device used for simulating vehicle component faults such as radar and vehicle lights. Common vehicle component faults include open circuit, short circuit and virtual connection. The fault setting box adopts a power anti-reverse connection protection circuit, an input signal protection circuit, an output signal protection circuit, a signal short circuit protection circuit, a DC / DC power conversion circuit, a fault setting circuit, a drive isolation circuit and a state indication circuit. By connecting to the vehicle management system, the student can recognize various fault phenomena and master the processing method when the intelligent and networked vehicle appears related faults without damaging the vehicle components.

[0005] The existing device only has open circuit, short circuit and virtual connection fault types when setting faults using the fault setting box. Some vehicle components use modular design, and the modules have hardware IDs, such as vehicle windows and radars. The control system controls the components in the module (such as front and rear windows and front, rear and left and right radars) respectively by identifying the ID in the module. The existing fault setting box does not contain the module ID fault identification function. When the module ID of the vehicle component is wrong, even if the module is in working condition, the control unit of the vehicle of the fault setting box cannot identify the fault type of the module because it cannot find the actual ID of the module. This causes great trouble for students to learn the fault of modular ID components, resulting in poor teaching effect. SUMMARY

[0006] In order to solve the problem of the existing technology that the module ID error cannot be identified, causing trouble for learning and poor teaching effect, the present application provides a vehicle module identification error fault type setting system, which has the characteristics of being able to simulate vehicle module ID error and being more conducive to teaching.

[0033] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative work belong to the protection scope of the present application.

[0034] With reference to Figure 1 The embodiments of the present application provide a vehicle module identification error fault type setting system, which comprises a communication interface, a fault setting module and a master control module.

[0035] The communication interface is connected with the automobile industrial computer and is used to receive the fault identification issued by the automobile industrial computer.

[0036] The fault setting module is connected with the communication interface and is used to connect the corresponding placeholder line connected with the master control module with the specified cable based on the fault identification.

[0037] The master control module is connected with the fault setting module and is used to receive the vehicle module identification signal after the corresponding placeholder line is connected with the specified cable, and generate the corresponding fault type.

[0038] Specifically, the system can adopt the mode of directly taking the power supply of the KL.15 bus end on the intelligent connected vehicle to provide the required power for the system. The communication interface is connected with the intelligent connected vehicle industrial computer. The corresponding commands are issued by the fault setting module to the fault setting to set the corresponding faults. The corresponding faults and measurement signals of the intelligent connected vehicle enter the fault setting box. After the processing of the master control module, the fault setting work is completed. In the specific application, the module ID placeholder line state changes with the hard-wired identity card. The module system is restarted, so that the module re-detects the module ID, causes the module ID to change, and realizes the implementation of the signal ID error fault.

[0039] As an implementable manner of the above-mentioned embodiments, with reference to Figure 3 and Figure 4As shown, the module ID refers to the module setting the ID through the placeholder line (ID line) and the four ways of connecting with the power + (positive electrode of power supply), power - (negative electrode of power supply), signal (module LIN signal) and ID suspension. Marked as ID+, DI-, ID-LIN and ID empty. In order to realize the setting of the ID fault of the module, the state of the placeholder line is modified logically, such as connecting the original placeholder ID empty and the positive electrode of the power supply together, realizing another ID identity of the module, at this time forming the same ID as the original ID, the vehicle system determines it as an ID fault, and the corresponding module stops working and no longer accepts the information sent by the ID module of ID+. The fault type setting is completed. After the fault setting is completed, the positive electrode of the module power supply is disconnected, the module is restarted, and the ID error fault type setting of the module is realized.

[0040] Referring to Figure 3 As shown, taking the vehicle ultrasonic radar module system as an example,

[0041] The radar module ID placeholder line is suspended (ID empty), indicating the left front middle ultrasonic radar;

[0042] The ID placeholder line is connected with the positive electrode of the radar power supply (ID+), indicating the left front side ultrasonic radar;

[0043] The ID placeholder line is connected with the negative electrode of the radar power supply (ID-), indicating the left rear side ultrasonic radar;

[0044] The ID placeholder line is connected with the radar LIN signal line (ID-LIN), indicating the left rear middle ultrasonic radar. After the fault setting box connects the suspended ID placeholder line (ID empty) of the left front middle ultrasonic radar with the radar LIN signal line, a new ID (ID-LIN) is formed, the ultrasonic radar module is restarted, and the automatic driving installation and adjustment training platform (the fault setting box is installed on it and is used to replace the real car) detects that there is no left front middle ultrasonic radar on the left side (because the ID empty is replaced by ID-LIN) and there are two left rear middle ultrasonic radars (ID-LIN). Therefore, the automatic driving installation and adjustment training platform does not accept the left front middle and left rear middle ultrasonic radar signals (neither no signal nor signal error is accepted, and the automatic driving installation and adjustment training platform does not accept the ultrasonic radar signal without ID detection and repeated ID detection, forming a fault). However, the power supply and LIN signal of the left front middle and left rear middle ultrasonic radar modules are normal and are in working state, so the fault type can be manufactured without disassembling and changing the radar wiring mode.

[0045] For another example, referring to Figure 4As shown, ID1+ID2 represents the left front window; ID1+ID3 represents the left rear window; ID2+ID3 represents the right front window; and ID1+ID2+ID3 represents the right rear window. When the ID fault setting is changed by using the fault setting box, the ID of the right rear window is changed to ID1+ID2, the automatic driving installation and adjustment training platform (the fault setting box is installed thereon and is used to replace the actual vehicle) detects that there is no right rear window (because the ID corresponding to the right rear window is replaced by (ID1+ID2)), and there are two left front windows (ID1+ID2), so the automatic driving installation and adjustment training platform does not accept the right rear and left front windows (neither the signal nor the signal error is detected by the automatic driving installation and adjustment training platform, and the ID is detected and the repeated ID is not accepted, so the window control signal is not accepted, and a fault is formed), but the power supply and the LIN signal of the right rear and left front window modules are normal and are in working state, so the fault type can be manufactured without dismounting and changing the window connection harness.

[0046] In some embodiments of the present application, the fault setting module comprises an automobile relay connected to the placeholder line and the specified cable, and the automobile relay is used for switching the connection of the placeholder line and the specified cable to generate a vehicle module identification signal.

[0047] The specified cable comprises a power supply positive pole, a power supply negative pole and a signal cable.

[0048] Referring to Figure 5 As shown, the automobile relay is an HFKD / 012-1ZS relay which adopts a single-knife double-throw form to realize the connection with other cables. It can be understood that other models of relays can also be used by those skilled in the art to realize the same switching function, and the present application will not be described here.

[0049] The power supply module is further included, and the power supply module is connected with the KL.15 bus on the automobile and is used to provide the required power supply for the communication interface, the fault setting module and the main control module.

[0050] The communication interface is based on 485 serial port data or CAN data for communication.

[0051] Referring to Figure 6 As shown, the power supply module comprises an isolation chip and a voltage stabilizing chip to protect and stabilize the power supply.

[0052] The main control module can be selected from an STM32F103 single-chip microcomputer, and the communication interface can be selected from a MAX3485E, which is a 3.3V low-power transceiver for RS-485 and RS-422 communication. Each device has a driver and a receiver, which can reduce EMI and reduce reflection caused by improper terminal matching cables, and realize error-free data transmission at a maximum of 250kbps.

[0053] Also include and host module connected state indicating module, state indicating module is used for indicating corresponding fault signal.

[0054] State indicating module can adopt as touch display screen or display screen with key or indicating lamp can indicate corresponding fault signal, give user most direct indication.

[0058] 103, the placeholder line and the specified cable are connected;

[0059] 104, power on and complete module identification fault setting.

[0060] Specifically, when setting fault, first control module power supply is disconnected, then the placeholder ID line and the specified signal line are connected, after the placeholder ID line and the specified signal line are connected, the module power supply is turned on, at this time, the fault setting is completed.

[0061] The vehicle module identification error fault type setting system and method provided by the above embodiment of the application change signal ID of intelligent network connected automobile, realize signal ID error fault type setting, when setting, the fault setting circuit realizes the fault of module ID placeholder line of modular production, after the fault setting is completed, the fault setting circuit restarts the module, so that the fault setting is successful, and the signal ID error fault type design can be realized.
