[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0025] As an important part of the vehicle circuit, vehicle grounding forms a current loop between the vehicle power supply, electrical loads and the ground. Improper selection of the grounding circuit may cause the circuit to burn out due to excessive current in the circuit, thus causing the safety hazard of spontaneous combustion of the vehicle. Or when a grounding point of the vehicle wiring harness is loose, it may cause some controller functions of the vehicle to fail. Therefore, it is necessary to test whether the design of each grounding point of the vehicle is reasonable and whether the grounding harness selection is reliable during the research and development stage.

[0026] In the related technology, the potential circuit verification of a vehicle is usually carried out on a real vehicle, which requires the vehicle to be assembled and the wiring harness to be installed, and then the vehicle to be disassembled to expose all the grounding points of the wiring harness. The assembly and disassembly of the vehicle is relatively cumbersome, which affects the design cycle of the vehicle wiring harness and increases the R&D cost.

[0027] Based on this, an embodiment of the present invention provides a method for verifying a potential circuit of a vehicle. A simulation circuit is established according to the line of the vehicle. After the simulation circuit is powered on, a first operating parameter of the first device can be obtained, and then any second grounding point 210 is controlled to be disconnected in turn, and then the second operating parameter of the first device is obtained. The first operating parameter is compared with the second operating parameter to see if there is a difference. When the first operating parameter is different from the second operating parameter, it is determined that there is a potential circuit in the line of the vehicle. There is no need to complete the assembly of the vehicle before verification, which improves the verification efficiency and helps to shorten the research and development cycle of the vehicle line.

[0028] refer to Figures 1 to 5 A vehicle potential circuit verification method according to an embodiment of the present invention is described. The vehicle potential circuit verification method is used to verify a vehicle circuit, wherein the circuit includes a first device and multiple second devices, wherein the first device has a grounding point 110 and a first grounding point 120, and the second device has a second grounding point 210, and multiple second grounding points 210 are connected to the first grounding point 120. The vehicle potential circuit verification method is described below using a specific example.

[0029] Reference Figure 1 As shown, the vehicle potential loop verification method includes the following steps.

[0030] Step S100, establishing a simulation circuit according to the circuit.

[0031] A simulation circuit is established according to the vehicle's circuit, and the simulation circuit can simulate the operation of the first device and multiple second devices in the vehicle's circuit. In the simulation circuit, the grounding point 110 and the first grounding point 120 of the first device are both used as grounding terminals, and the second grounding point 210 of each second device is connected to the first grounding point 120 of the first device, so that the second device is grounded.

[0032] Parameters such as the input voltage and input current of the simulation circuit are consistent with those during actual line operation, ensuring that the simulation circuit simulates the line operation of the vehicle.

[0033] Step S200, controlling the simulation circuit to be powered on to obtain a first operating parameter of the first device.

[0034] The simulation circuit is powered on and running. Since the first grounding point 120 of the first device and the second grounding points 210 of multiple second devices are normal, the first device can operate normally, and a first operating parameter for the normal operation of the first device is obtained. The first operating parameter may be a current, voltage, power or other parameter.

[0035] Step S300: Control any one of the second grounding points 210 to be disconnected, control the remaining second grounding points 210 to be connected to the first grounding point 120, and obtain the second operating parameter of the first device.

[0036] To control the second grounding point 210 of any second device to be disconnected, the line of the second grounding point 210 can be directly deleted in the simulation circuit; or a switch can be set between the second grounding point 210 and the second device to control the second device to be disconnected from the second grounding point 210 through the switch.

[0037] When the second grounding point 210 of any second device is disconnected, the second operating parameters of the second device are also obtained. The second operating parameters may be parameters such as current, voltage, and power. The form of the second operating parameters is consistent with that of the first operating parameters to facilitate subsequent comparison of the second operating parameters with the first operating parameters.

[0038] Step S400, determining whether the first operating parameter is the same as the second operating parameter. When the first operating parameter is different from the second operating parameter, determining that a potential loop exists in the line.

[0039] The first device has a first grounding point 120 and a grounding point 110, that is, the first device has two grounding points. When the vehicle line operates normally, the first device can maintain normal operation even if the first grounding point 120 fails. The first operating parameter is obtained when the first device operates normally, and subsequent verification uses the first operating parameter as a standard.

[0040] The second device has a second grounding point 210. When the second grounding point 210 of the second device is disconnected, that is, the failure of the second grounding point 210 of the second device is simulated, the second device should be in a state of stopping operation. Since the first device and the second device are in a parallel relationship, when the line is normal, the cessation of operation of the second device will not cause a large change in the second operating parameter of the first device. Therefore, when the difference between the second operating parameter and the first operating parameter is within the normal measurement deviation range, it can be determined that when the grounding point of the second device fails, the vehicle's line still maintains normal operation, that is, there is no potential loop in the vehicle's line.

[0041] However, when a potential loop exists in the vehicle's circuit, when the second grounding point 210 of the second device fails, since the first grounding point 120 of the first device is connected to the second grounding point 210 of the second device, the potential loop causes the current of the second device to flow through the first device to the grounding point 110, causing the second operating parameter of the first device to change, resulting in a large difference between the second operating parameter and the first operating parameter. It can be determined that the operation of the first device is abnormal, and then it is determined that the operation of the vehicle's circuit is abnormal, and it is determined that there is a potential loop in the vehicle's circuit.

[0042] Therefore, a simulation circuit is established according to the vehicle's circuit. After the simulation circuit is powered on, the first operating parameter of the first device can be obtained, and then any second grounding point 210 is controlled to be disconnected in turn, and then the second operating parameter of the first device is obtained, and the first operating parameter is compared with the second operating parameter to see if there is a difference. When the first operating parameter is different from the second operating parameter, it is determined that there is a potential loop in the vehicle's circuit. There is no need to complete the assembly of the vehicle before verification, which improves the verification efficiency and helps to shorten the research and development cycle of the vehicle circuit.

[0043] In some embodiments, reference Figure 1 As shown, the vehicle potential loop verification method also includes the following steps.

[0044] Step S500: When it is determined that a potential loop exists in the line, the input voltage of the line is obtained, and the risk level is determined according to the input voltage.

[0045] When it is determined that there is a potential loop in the line, if the current of the potential loop is too large, it will cause the line to self-ignite, so it is necessary to evaluate the risk level of the potential loop. In this embodiment, the current of the potential loop is generally determined by the input voltage of the line. The larger the input voltage, the larger the current of the potential loop. Therefore, the risk level can be divided into different intervals according to the voltage. It is judged that the obtained input voltage belongs to a certain interval, and then the corresponding risk level is obtained.

[0046] The higher the risk level, the greater the risk of spontaneous combustion of the line, and the higher the priority of the line to be improved. When redesigning the improved line, multiple lines that need to be improved can be improved in order from high to low risk levels, so as to avoid the situation where the improvement of low-risk lines causes changes in high-risk lines and affects the line optimization efficiency when improving multiple lines.

[0047] In some embodiments, reference Figure 2 and Figure 5 As shown, step S100, establishing a simulation circuit according to the circuit, includes the following steps.

[0048] Step S110 , setting a first virtual controller 100 to simulate a first device, and setting a plurality of second virtual controllers 200 to simulate a plurality of second devices.

[0049] In the simulation circuit, a first device is simulated by a first virtual controller 100 , and a second device is simulated by a second virtual controller 200 .

[0050] The first virtual controller 100 can simulate the input and output of the first device, and can also simulate the communication interface between the first device and other devices to facilitate simulated interaction, thereby simulating the performance and functional logic of the first device. Similarly, the second virtual controller 200 can simulate the performance and functional logic of the second device.

[0051] In this embodiment, attention is paid to the input parameters and output parameters of the first virtual controller 100 and the second virtual controller 200 to determine whether there is a potential loop in the simulation circuit when any second grounding point 210 is disconnected. The first operating parameter and the second operating parameter can be directly obtained through the output current, output voltage, output power, etc. of the first virtual controller 100 under different operating states.

[0052] In some embodiments, reference Figure 2 and Figure 5 As shown, step S100, establishing a simulation circuit according to the line, also includes the following steps.

[0053] Step S120 , setting a virtual switch 300 between each second virtual controller 200 and the corresponding second grounding point 210 .

[0054] In order to conveniently control the disconnection of any second grounding point 210 , a virtual switch 300 is provided between each second virtual controller 200 and each second grounding point 210 , and the virtual switch 300 directly controls the on and off of the second virtual controller 200 and the second grounding point 210 .

[0055] Step S300, controlling any second grounding point 210 to be disconnected, includes the following steps.

[0056] Step S310 , controlling any one virtual switch 300 to be opened, and controlling the remaining multiple virtual switches 300 to be closed.

[0057] Since multiple second grounding points 210 are connected, if there is a potential loop in the line, multiple second virtual controllers 200 may form a potential loop through the second grounding point 210. If multiple virtual switches 300 are disconnected, the potential loop may be disconnected, affecting the subsequent verification results. Therefore, in this embodiment, it is necessary to control one virtual switch 300 to be disconnected and the remaining multiple virtual switches 300 to be closed, so as to verify the disconnection of multiple second grounding points 210 one by one to avoid disconnecting the potential loop.

[0058] In some embodiments, the first operating parameter of the first device is a first current and / or a first voltage, and the second operating parameter of the first device is a second current and / or a second voltage. Figure 3 As shown, step S400, determining whether the first operating parameter is the same as the second operating parameter, includes the following steps.

[0059] Step S410, calculating a current difference between a first current and a second current and / or calculating a voltage difference between a first voltage and a second voltage.

[0060] When judging the first operating parameter and the second operating parameter, due to the different accuracy of the simulation circuit, the simulation circuit may have slight measurement deviation fluctuations, that is, there will be errors in the current and voltage parameters of the first device, so it is necessary to calculate the current difference between the first current and the second current, and calculate the voltage difference between the first voltage and the second voltage, and evaluate whether there is a significant change in the operating state of the first device through the current difference or the voltage difference.

[0061] Step S420: When the current difference is greater than a preset current threshold or when the voltage difference is greater than a preset voltage threshold, it is determined that the first operating parameter is different from the second operating parameter.

[0062] When the current difference exceeds the preset current threshold or when the voltage difference exceeds the preset voltage threshold, it proves that there is a large difference between the first operating parameter and the second operating parameter of the first device, and it can be determined that the operation of the first device is abnormal, and then it is determined that there is a potential loop in the line.

[0063] In some embodiments, reference Figure 4 As shown, the verification method also includes the following steps.

[0064] Step S600 , after the simulation circuit is powered on, the first device is controlled to be turned off, and a third current of the grounding point 110 and / or a third voltage between the first grounding point 120 and the grounding point 110 are obtained.

[0065] After the simulation circuit is powered on, the housing of the first device is connected to the grounding point 110, and the grounding point 110 is grounded. When the first device is in the off state, the third current of the grounding point 110 is measured, and the third voltage between the first grounding point 120 and the grounding point 110 is measured. When there is no potential loop in the vehicle's circuit, the third current and the third voltage are generally 0.

[0066] Step S700: When the third current is greater than a preset current or the third voltage is greater than a preset voltage, it is determined that a potential loop exists in the circuit.

[0067] When the third current exceeds the preset current or when the third voltage exceeds the preset voltage, it proves that current still flows after the first device is turned off, proving that there is a potential loop in the circuit. In this embodiment, when multiple second devices in the circuit have a potential loop, the third voltage is equal to the input voltage of the circuit.

[0068] In some embodiments, the verification method further includes the following steps.

[0069] Step S90 , before executing the control simulation circuit to be powered on, detecting the first device and all the second devices, and confirming that the first device and all the second devices operate normally.

[0070] In order to ensure that the results of the simulation circuit verification are valid, it is necessary to detect the first device and all second devices before the simulation circuit is powered on to ensure that the first device and all second devices can operate normally to avoid potential loops in the simulation circuit due to damage to the first device or the second device.

[0071] In addition, an embodiment of the present invention also provides a vehicle potential loop verification device for verifying the vehicle's circuit, the circuit including a first component and multiple second components, the first component having a grounding point and a first grounding point, the grounding point being grounded, the second component having a second grounding point, and the multiple second grounding points being connected to the first grounding point.

[0072] The verification device includes a first execution module, a second execution module, a first acquisition module, a third execution module, a second acquisition module, and a judgment module.

[0073] The first execution module is used to establish a simulation circuit according to the circuit, the second execution module is used to control the simulation circuit to be powered on, so that the first device can simulate operation, and the first acquisition module is used to acquire the first operation parameter of the first device.

[0074] The third execution module is used to disconnect any second grounding point, and the remaining second grounding points are kept connected to the first grounding point, and the second acquisition module is used to acquire the second operating parameter of the first device.

[0075] The judgment module is used to judge whether the first operating parameter is equal to the second operating parameter. When the first operating parameter is different from the second operating parameter, the judgment module determines that there is a potential loop in the circuit.

[0076] The above verification device executes the vehicle potential circuit verification method in the above embodiment.
