Another solution is to use a desktop flash cable: insert the ECU into the flash connector, and connect the external device power supply to provide 12V normal power. Use the ES581 flash cable to communicate with the ECU, flash the calibration data and update the software through the host computer, manually replace the ECU after the flash is completed, and continue to flash the ECU until all ECUs are flashed.

[0049] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.
[0050] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.
[0051] In this article, "first", "second", etc. do not indicate their importance or order, but are only used to indicate the difference between each other for the convenience of document description.
[0052] In order to make the drawings concise, each figure only schematically shows the parts related to the utility model, which do not represent the actual structure of the product.
[0053] Figure 1 FIG. 1 shows a schematic diagram of an ECU flash wiring harness 10 according to an exemplary embodiment of the present utility model. Figure 1As shown, the ECU flashing harness 10 includes a harness body 11. The harness body 11 includes a cable 110. The cable 110 includes a plurality of power supply wires and a plurality of communication wires.
[0054] The ECU flash harness 10 also includes a terminal 12, a first ECU interface 13, a second ECU interface 15, a first OBD interface 14 and a second OBD interface 16. The terminal 12 is used to connect a DC power supply, such as a DC power supply that provides a 12V power supply voltage. The power supply pin of the first ECU interface 13 is connected to the terminal 12 via a first group of power supply wires 111 in the cable 110, the power supply pin of the second ECU interface 15 is connected to the terminal 12 via a second group of power supply wires 113 in the cable 110, the power supply pin of the first OBD interface 14 is connected to the terminal 12 via a third group of power supply wires 115 in the cable 110, and the power supply pin of the second OBD interface 16 is connected to the terminal 12 via a fourth group of power supply wires 117 in the cable 110. Thus, a DC power supply is provided to each ECU connector and each OBD connector through an ECU flash harness. The communication pin of the first ECU interface 13 is connected to the communication pin of the first OBD interface 14 via the first group of communication wires 112 in the cable 110, and the communication pin of the second ECU interface 15 is connected to the communication pin of the second OBD interface 16 via the second group of communication wires 114 in the cable 110 or connected to the communication pin of the first OBD interface 14 via the first group of communication wires 112, respectively constituting the communication branches of the first ECU interface 13 and the second ECU interface 15, i.e., the flashing branches. Each group of wires adopts twisted pair signal shielded wires to prevent electromagnetic interference between the flashing branches. In this way, the communication path of the ECU is realized through the same ECU flashing harness.
[0055] In an illustrative embodiment, the first OBD interface 13 and the second OBD interface 15 are vehicle-mounted OBD interfaces, that is, female OBD interfaces, but not limited to this, and can also be male OBD interfaces. This makes it compatible with existing OBD diagnostic equipment, and while realizing the flashing of calibration data of ECUs of different manufacturers through a flashing harness, the OBD diagnostic equipment can be connected to read relevant information of the ECU. For example, a diagnostic instrument is used to communicate with the ECU to read information such as the ECU manufacturer, model, software and hardware version number, etc. There is no need to read ECU data on the vehicle end, thereby improving the efficiency, adaptability and convenience of ECU data reading.
[0056] like Figure 1As shown, the ECU flash wiring harness 10 also has a control switch 19 for simultaneously controlling the connection or disconnection between the first ECU interface 13, the second ECU interface 15, the first OBD interface 14, and the second OBD interface 16 and the terminal 12. Each flash branch shares a power switch control to avoid short circuit or open circuit when each flash branch uses an independent switch control to connect or disconnect with the DC power supply.
[0057] By constructing an independent flashing branch for each ECU in the ECU flashing harness 10, a flashing harness for ECU calibration data of different electronic control systems is provided which has high flashing efficiency, strong applicability, simple process and convenient use, and at the same time realizes power supply and communication for flashing of multiple ECUs, so that calibration data of ECUs of different manufacturers can be flashed simply, quickly and conveniently through one flashing harness directly at the office workstation.
[0058] Figure 2 FIG. 1 shows a schematic diagram of an ECU flash wiring harness 10 according to another exemplary embodiment of the present utility model. Figure 2 As shown, the ECU flashing harness 10 further includes an adapter 116. The adapter 116 connects the first ECU interface 13 and the first OBD interface 14 via the first group of communication wires 112. Thus, the calibration data of ECUs of different manufacturers can be flashed through one flashing harness.
[0059] In an exemplary embodiment, Figure 2 As shown, the adapter 116 is an adapter cable, but is not limited thereto. The adapter 116 converts the communication pins of the first ECU interface to match the communication pins of the first OBD interface 13. For example, the OBD interface usually has 16 pins, the communication pins of the first ECU interface 13 correspond to the "3rd" and "11th" pins of the OBD interface, and the communication pins of the second ECU interface 15 correspond to the "6th" and "14th" pins of the OBD interface. The communication pins of the first ECU interface 13 are converted to correspond to the "6th" and "14th" pins of the OBD interface through the adapter 116. In this way, multiple ECUs that need to be connected to different groups of communication pins of the OBD interface can be connected to the same group of communication pins of the same OBD interface (in this embodiment, connected to the first OBD interface 14), such as the "6th" and "14th" pins.
[0060] In the ECU flashing harness 10, more ECU interfaces may be included, wherein a part of the ECU interfaces are connected to the communication pins of the same OBD interface, such as the "6th" and "14th" pins, after being transferred via their respective transfer lines 116, and the remaining ECU interfaces are connected to the communication pins of the aforementioned same OBD interface, such as the "6th" and "14th" pins. In this way, one OBD interface is connected to multiple ECU interfaces, so that the calibration data of ECUs of different manufacturers can be flashed through one flashing harness.
[0061] Figure 3 Shows Figure 1 FIG. 1 is a schematic diagram of another exemplary embodiment of a branch of the ECU flash wiring harness 10. Figure 3 As shown, the ECU flash harness 10 includes at least one first ECU interface 13, at least one regulating element 119 and a hub 118, thereby forming a branch of the ECU flash harness 10. In this branch, the number of regulating elements 119 is the same as the number of first ECU interfaces 113. One end of each regulating element 119 is connected to the communication pin of the first ECU interface 113 corresponding to each other to balance the current of each flash branch. The output end of the hub 118 is connected to the other end of each regulating element 119, and the input end of the hub 118 is connected to the communication pin of the OBD interface. In this way, one OBD interface is connected to multiple ECU interfaces, and multiple ECU calibration data are flashed at the same time.
[0062] The ECU flash harness 10 may include a plurality of such branches to constitute the ECU flash harness 10. For example, in one branch, a plurality of ECU interfaces correspond to the "6th" and "14th" pins of the OBD interface, in another branch, a plurality of ECU interfaces correspond to the "3rd" and "11th" pins of the OBD interface, and in another branch, a plurality of ECU interfaces correspond to the "1st" and "9th" pins of the OBD interface, thereby realizing the simultaneous flashing of calibration data of a plurality of ECUs of a plurality of manufacturers through a flash harness.
[0063] In an exemplary embodiment, the regulating element is a USB-CAN adapter. For example, when the ECU flashing harness 10 includes multiple branches, in one branch, the "6" and "14" pins of the OBD interface are connected to the input end of the hub, and the communication pins of multiple ECU interfaces are connected to the output end of the hub via their respective USB-CAN connectors; in another branch, the "3" and "11" pins of the OBD interface are connected to the input end of the hub, and the communication pins of multiple ECU interfaces are connected to the output end of the hub via their respective USB-CAN connectors; in another branch, the "1" and "9" pins of the OBD interface are connected to the input end of the hub, and the communication pins of multiple ECU interfaces are connected to the output end of the hub via their respective USB-CAN connectors. In this way, the calibration data of multiple ECUs of multiple manufacturers can be flashed simultaneously through one flashing harness.

Figure 5 Shown by Figure 2 The illustrated schematic diagram is a schematic diagram of an exemplary implementation of an ECU flashing device 100 formed by an ECU flashing harness 10 . Figure 6 Shown by Figure 3 The schematic diagram of an exemplary implementation of an ECU flashing device 100 formed by an ECU flashing wiring harness 10 composed of branches of the ECU flashing wiring harness is shown.
[0065] like Figures 4 to 6 As shown, the ECU flashing device 100 includes an ECU flashing harness 10, a power adapter 20 and at least one CAN connector 30. The terminal 12 is connected to a DC power source through the power adapter 20, for example, a 220V mains power supply. The number of CAN connectors 30 is the same as the number of OBD interfaces of the ECU flashing harness 10. One end of each CAN connector 30 is a USB interface that matches the USB interface of the electronic device 200, and is used to connect the electronic device 200. The electronic device 200 is, for example, a computer, but is not limited thereto, and can be, for example, any other applicable electronic device. The other end of each CAN connector 30 is an OBD interface that is compatible with the vehicle-mounted OBD interface, and is used to connect the first OBD interface 113 or the second OBD interface 115. Thereby, communication with the ECUs plugged into each ECU interface is achieved, and the ECU calibration data is flashed. In this way, the calibration data of ECUs of different manufacturers can be flashed through a flashing harness.
[0066] In an exemplary embodiment, the CAN connector 30 includes one or more of ES581, ES582 and KVASER interface cards, thereby realizing the flashing of calibration data of multiple ECUs of multiple manufacturers through one flashing harness.
[0067] In summary, the utility model provides a flashing wiring harness for ECU calibration data of different electronic control systems with high flashing efficiency, strong applicability, simple process and convenient use, and realizes power supply and communication of multiple ECU flashing at the same time, so as to improve the convenience, versatility and economy of flashing ECU calibration data. Therefore, it is possible to flash the calibration data of ECUs of different manufacturers simply, quickly and conveniently through a flashing wiring harness directly at the office workstation.
