DETAILED DESCRIPTION

[0028] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, and circuits are omitted to prevent unnecessary details from obstructing the description of the present application.

[0029] With the rapid development of intelligent driving technology, more and more vehicles are using intelligent driving technology to save manpower. Vehicles are equipped with in-vehicle Ethernet devices, among which the domain controller is the core device in the in-vehicle Ethernet device, which is usually composed of SOC chips and MCU chips. Among them, the SOC chip is used to process the camera images of the vehicle camera and output the target recognition list through the deep learning algorithm. At the same time, it can also realize sensor fusion, trajectory prediction, environmental model building, self-vehicle positioning and other functions. The MCU chip is used to perform logical operations with a high functional safety level. For example, the planning and control, communication, diagnosis of autonomous driving vehicles, and the external interface of the domain controller are all run in the MCU chip.

[0030] At present, it is usually necessary to test the SOC chip and the MCU chip. In the test process of the related technology, the electronic device (for example, a computer) is usually connected to the serial port of the domain controller through a twisted pair cable to read the data of the chip in the domain controller. Here, it is worth noting that the domain controller outputs the vehicle Ethernet signal to the electronic device at this time. In this connection mode, the electronic device receives the vehicle Ethernet signal, which usually adopts Ethernet protocols such as BroadR-Reach (i.e., 100BASE-T1 and 1000BASE-T1). The electronic device cannot debug the signal using this Ethernet protocol, that is, the electronic device cannot directly debug the data in the vehicle Ethernet signal. When the electronic device in the related technology tests the data of the chip abnormal, it is usually necessary to remove the domain controller and take it to the bench for debugging. The bench can directly debug, test and verify the vehicle Ethernet signal under non-real vehicle conditions. After debugging, the domain controller is installed on the PCB for testing until the data meets the test standard. In this way, the test process is complicated, the test efficiency is low, and the anti-interference performance is poor. Secondly, the electronic device in the related technology cannot copy and collect the data in the vehicle Ethernet signal.

[0031] To this end, the present application provides a vehicle-mounted converter and a vehicle, which can convert the vehicle-mounted Ethernet signal into an industrial Ethernet signal that can be recognized by the electronic device, so that the electronic device can directly debug the data in the vehicle-mounted Ethernet device, simplifying the testing process and improving the testing efficiency. At the same time, it can also realize two-way copying between the electronic device and the vehicle-mounted Ethernet device.

[0032] The vehicle-mounted converter and vehicle provided in the present application are exemplarily introduced below with reference to the accompanying drawings.

[0033] When testing a test component using in-vehicle Ethernet, it is generally necessary to use an Ethernet monitoring device using industrial Ethernet, such as a computer, to test the test component using in-vehicle Ethernet. Therefore, it is necessary to convert the in-vehicle Ethernet signal used by the test component into an industrial Ethernet signal for testing. To this end, an embodiment of the present application provides a vehicle, such as Figure 1 As shown, it includes an in-vehicle Ethernet device 100 and an in-vehicle converter 200. When an electronic device 300 (such as an industrial computer such as a computer) is needed to test the in-vehicle Ethernet device 100, the in-vehicle converter 200 can convert the in-vehicle Ethernet signal used by the in-vehicle Ethernet device 100 into an industrial Ethernet signal to enable the electronic device 300 to test it.

[0034] Among them, the in-vehicle Ethernet device 100 can be a SOC chip in a domain controller, or can be other system chips using in-vehicle Ethernet. This application does not make any specific restrictions on this.

[0035] Optionally, when the vehicle-mounted Ethernet device 100 needs to be tested, the vehicle-mounted Ethernet device 100 can be connected to the vehicle-mounted converter 200 through a plug. When the two are connected, the vehicle-mounted Ethernet device 100 will output a vehicle-mounted Ethernet signal to the vehicle-mounted converter 200, so that the vehicle-mounted converter 200 converts it and transmits it to the electronic device 3 for testing, exporting, etc.; when the vehicle-mounted Ethernet device 100 does not need to be tested, the vehicle-mounted Ethernet device 100 can be separated from the vehicle-mounted converter 200.

[0036] In order to enable the electronic device 300 to collect and debug the data in the vehicle Ethernet device 100, in one example, Figure 2 As shown, the vehicle-mounted converter 200 is provided with a vehicle-mounted Ethernet interface and an industrial Ethernet interface. The vehicle-mounted Ethernet interface is connected to the vehicle-mounted Ethernet device 100, and the industrial Ethernet interface is connected to the electronic device 300. The vehicle-mounted converter 200 may include a first Ethernet conversion chip 210 and a second Ethernet conversion chip 220. The first end of the first Ethernet conversion chip 210 is connected to the vehicle-mounted Ethernet device 100, and the first Ethernet conversion chip 210 is used to receive the vehicle-mounted Ethernet signal provided by the vehicle-mounted Ethernet device 100 and convert it into a PHY signal. The first end of the second Ethernet conversion chip 220 is connected to the second end of the first Ethernet conversion chip 210, and the second end of the second Ethernet conversion chip 220 is connected to the electronic device 300. The second Ethernet conversion chip 220 is used to receive the PHY signal transmitted by the first Ethernet conversion chip 210 and convert it into an industrial Ethernet signal and transmit it to the electronic device 300.

[0037] In this way, when the electronic device 300 is required to test the vehicle Ethernet device 100, the first Ethernet conversion chip 210 will first convert the vehicle Ethernet signal into a PHY signal. At this time, since the second Ethernet conversion chip 220 is connected to the first Ethernet conversion chip 210, the second Ethernet conversion chip 220 will receive the PHY signal and convert the PHY signal into an industrial Ethernet signal for transmission, that is, the signal output by the second Ethernet conversion chip 220 to the electronic device 300 is the industrial Ethernet signal corresponding to the vehicle Ethernet. The industrial Ethernet signal adopts the IEEE 802.3 Ethernet protocol. The electronic device can debug the signal using this Ethernet protocol. In this way, the electronic device 300 can collect, record and export the data in the industrial Ethernet signal. When the data is detected to be abnormal, the data can be directly debugged to realize software flashing, simplifying the test process and improving the test efficiency. At the same time, the electronic device 300 can also transmit the debugged data back to the vehicle Ethernet device 100, realizing a two-way copy between the vehicle Ethernet device 100 and the electronic device 300.

[0038] Optionally, the chip model of the first Ethernet conversion chip 210 may be TJA1101. TJA1101 adopts a 100Mbps automotive Ethernet standard, namely 100BASE-T1. When the first Ethernet conversion chip 210 is TJA1101, the power consumption of the first Ethernet conversion chip 210 is relatively low.

[0039] Optionally, the chip model of the second Ethernet conversion chip 220 may be KSZ8041.

[0040] In order to ensure the normal use of the first Ethernet conversion chip 210 and the second Ethernet conversion chip 220, in one example, Figure 3 As shown, the vehicle-mounted converter 200 may further include a power module 230, which is respectively connected to the power supply interface of the first Ethernet conversion chip 210 and the power supply interface of the second Ethernet conversion chip 220. When the electronic device 300 needs to test the vehicle-mounted Ethernet device 100, the power module 230 supplies power to the first Ethernet conversion chip 210 and the second Ethernet conversion chip 220 to ensure the normal use of the first Ethernet conversion chip 210 and the second Ethernet conversion chip 220, so that the electronic device 300 can collect, record, export and test the data of the vehicle-mounted Ethernet device 100 through the vehicle-mounted converter 200.

[0041] In order to prevent the power supply voltage provided by the power supply module 230 from being too large, which may cause the first Ethernet conversion chip 210 and the second Ethernet conversion chip 220 to be damaged, in one example, Figure 4 As shown, the vehicle-mounted converter 200 may further include a voltage conversion module 240, one end of which is connected to the power module 230, and the other end of which is respectively connected to the power supply interface of the first Ethernet conversion chip 210 and the power supply interface of the second Ethernet conversion chip 220. When the electronic device 300 needs to test the vehicle-mounted Ethernet device 100, the vehicle-mounted converter 200 is respectively connected to the vehicle-mounted Ethernet device 100 and the electronic device 300, and the power module 230 outputs a 5V power supply voltage, which is stepped down to 3.3V by the voltage conversion module 240 and then output to the power supply interface of the first Ethernet conversion chip 210 and the power supply interface of the second Ethernet conversion chip 220, so as to avoid the problem that the power supply voltage provided by the power module 230 is too large, resulting in damage to the first Ethernet conversion chip 210 and the second Ethernet conversion chip 220, thereby ensuring the power supply reliability, and further ensuring the conversion reliability of the first Ethernet conversion chip 210 and the second Ethernet conversion chip 220.

[0042] Optional, such as Figure 5As shown, the voltage conversion module 240 may include a conversion chip U1, a first resistor R1, a second resistor R2 and a first capacitor C1, the first end 1 of the conversion chip U1 is connected to one end 1 of the first resistor R1, the second end 2 of the conversion chip U1 is connected to one end of the second resistor R2, the other end of the first resistor R1 is connected to the other end of the second resistor R2 and to the first plate of the first capacitor C1, and the second plate of the first capacitor C1 is grounded.

[0043] The voltage conversion module 240 may also include a second capacitor C2, the third terminal 3 and the fourth terminal 4 of the conversion chip U1 are the first transmitting terminal TX+ and the second transmitting terminal TX-, the fifth terminal 5 and the sixth terminal 6 of the conversion chip U1 are the first receiving terminal RX+ and the second receiving terminal RX-, the seventh terminal 7 and the eighth terminal 8 of the conversion chip U1 are respectively connected to the 3.3V voltage and are connected to the first plate of the second capacitor C2, and the second plate of the second capacitor C2 is grounded.

[0044] Here, it is worth noting that the voltage conversion module 240 in the present application can also adopt other circuits or devices with a step-down function, and the present application does not make any specific restrictions on this.

[0045] A vehicle is generally provided with a plurality of electronic control units (ECUs), which are used to control the driving state of the vehicle and enable the vehicle to realize various functions, and the plurality of ECUs are respectively connected to the vehicle Ethernet device 100, wherein the working mode of the vehicle Ethernet device 100 generally includes a master mode and a slave mode to adapt to different ECUs. In order to make the vehicle converter 200 provided in the present application also adapt to different ECUs, in one example, as Figure 6 As shown, the vehicle-mounted converter 200 provided by the present application may also include a single-chip microcomputer chip U2, the first end of which is connected to the vehicle-mounted Ethernet device 100. The single-chip microcomputer chip U2 can enable the vehicle-mounted converter 200 to adapt to the master mode and slave mode of the vehicle-mounted Ethernet device to adapt to different ECUs. For example, when a certain ECU is in slave mode, the single-chip microcomputer chip U2 can switch the vehicle-mounted Ethernet device 100 to a slave working mode to adapt to different ECUs. Moreover, the single-chip microcomputer chip U2 can also realize communication mode management, communication data monitoring, etc. of the vehicle-mounted Ethernet device 100.

[0046] Further, such as Figure 6As shown, the second end of the single-chip microcomputer chip U2 is connected to the first end of the switch 250, and the second end of the switch 250 is connected to the vehicle Ethernet device 100. The single-chip microcomputer chip 250 receives the vehicle Ethernet signal transmitted by the vehicle Ethernet device 100, and outputs a switch signal to the switch 250 to control the on and off of the switch 250 accordingly, so as to adapt to different modes. Exemplarily, when it is necessary to switch to the slave mode, the single-chip microcomputer chip U2 transmits a switch signal characterized as on to the switch 250, so that the switch 250 is turned on. When it is necessary to switch to the master mode, the single-chip microcomputer chip U2 transmits a switch signal characterized as off to the switch 250, so that the switch 250 is turned off. In this way, by controlling the on and off of the switch 250, the switching of the working mode can be realized, and the operation is simple.

[0047] Optionally, the switch 250 may be a PNP transistor, an NPN transistor, a relay, an N-type metal oxide semiconductor (NMOS) or a P-type metal oxide semiconductor (NMOS), etc., or may be other circuits and devices with switching functions, and the present application does not impose any specific restrictions on this.

[0048] In order to gain real-time insight into the testing process, in one example, Figure 6 As shown, the single-chip microcomputer chip also includes a prompter 260, which is connected to the third end of the single-chip microcomputer chip U2. When in the test state, the prompter 260 is turned on to remind that it is in the test state at this time; when not in the test state, the prompter 260 is turned off to remind that it is not in the test state at this time.

[0049] Optionally, the prompter 260 may be a device with a prompting function such as a light emitting diode (LED), a speaker, or other devices, and the present application does not impose any specific limitation on this.

[0050] like Figure 6 As shown, the vehicle-mounted converter 200 may also include a third resistor R3 and a fourth resistor R4. The fourth end of the single-chip microcomputer chip U2 and the fifth end of the single-chip microcomputer chip U2 are respectively connected to the third resistor R3 and the fourth resistor R4 for outputting internal input signals. The sixth and seventh ends of the single-chip microcomputer chip U2 are used to output internal output signals. The eighth and ninth ends of the single-chip microcomputer chip U2 are connected to a 3.3V voltage, and the tenth end of the single-chip microcomputer chip U2 is grounded.

[0051] In this way, the present application integrates the first Ethernet conversion chip 210, the second Ethernet conversion chip 220, the power module 230, the voltage conversion module 240, the switch 250, and the prompter 260 into a vehicle-mounted converter 200, which has high integration and low manufacturing cost, and enables the vehicle-mounted converter 200 to have multiple functions.

[0052] In summary, the vehicle-mounted converter 200 provided in the embodiment of the present application can convert the vehicle-mounted Ethernet signal provided by the vehicle-mounted Ethernet device 100 and output it to the electronic device 300. For example, when the electronic device 300 needs to test the vehicle-mounted Ethernet device 100, the first Ethernet conversion chip 210 will first convert the vehicle-mounted Ethernet signal into a PHY signal. At this time, since the second Ethernet conversion chip 220 is connected to the first Ethernet conversion chip 210, the second Ethernet conversion chip 220 will receive the PHY signal and convert the PHY signal into an industrial Ethernet signal for transmission, that is, the signal output by the second Ethernet conversion chip 220 to the electronic device 300 is the industrial Ethernet signal corresponding to the vehicle-mounted Ethernet. The industrial Ethernet signal adopts the IEEE 802.3 Ethernet protocol. The electronic device can debug the signal adopting this Ethernet protocol. In this way, the electronic device 300 can collect, record and export the data in the industrial Ethernet signal. When data abnormality is detected, the data can be directly debugged to realize software flashing, which simplifies the test process and improves the test efficiency. At the same time, the electronic device 300 can also transmit the debugged data back to the in-vehicle Ethernet device 100 , thereby realizing a two-way copy between the in-vehicle Ethernet device 100 and the electronic device 300 .
