[0047] Example 1

[0048] See Figure 1-2 As shown, this utility model provides a control device for an electronic controller, including a communication module 1 and a protocol converter 2, wherein the protocol converter 2 is connected to the communication module 1 and the electronic controller 3.

[0049] In this embodiment, the communication module 1 includes a host computer 101 and an analyzer 102. The analyzer 102 is connected to the host computer 101 and the protocol converter 2. The host computer 101 sends a signal encoded in USB format to the analyzer 102. The analyzer 102 converts the signal encoded in USB format into a signal encoded in LIN / CAN format and sends it to the protocol converter 2, so that the protocol converter 2 converts the signal encoded in LIN / CAN format into a communication data signal in the target encoding format of 2 / 4 / 8 / 16FSK. The analyzer 102 is a general CAN / LIN analyzer such as Vector or DOMOS.

[0050] After receiving the communication data signal in the target encoding format, the electronic controller 3 performs software flashing to enable control of the electronic controller 3. The electronic controller 3 sends the control result as a feedback signal in the 2 / 4 / 8 / 16FSK target encoding format to the protocol converter 2. The protocol converter 2 converts the 2 / 4 / 8 / 16FSK target encoding format feedback signal into a LIN / CAN encoding format signal and sends it to the analyzer 102. The analyzer 102 then converts the LIN / CAN encoding format signal into a USB encoding format feedback signal and sends it to the host computer 101. This allows the operator to view the control result through the host computer 101, which indicates whether the software flashing of the electronic controller 3 was successful.

[0051] The communication module 1 is used to receive the data signal to be converted from the program to be flashed selected by the staff, and send the data signal to be converted to the protocol converter 2, so that the protocol converter 2 can convert the data signal to be converted in different encoding formats into the communication data signal in the target encoding format. The encoding format of the data signal to be converted includes, but is not limited to, serial port SP encoding format, LIN encoding format, CAN encoding format, Ethernet encoding format and USB encoding format. These encoding formats are the encoding formats of the general bus interface built into the host computer 101 or the test and diagnostic instrument 103 used by the staff to control the electronic controller 3 (software flashing). The target encoding format includes the 2 / 4 / 8 / 16FSK encoding formats that the electronic controller 3 is allowed to receive, so that the staff can control the electronic controller 3 (software flashing) through the UDS (Unified Diagnostic Service) standard protocol using the host computer 101 or the test and diagnostic instrument 103. For the specific process of controlling the electronic controller 3, please refer to the prior art.

[0054] The signal output unit 203 is also used to receive feedback signals in 2 / 4 / 8 / 16FSK target encoding format sent by the electronic controller 3. The feedback signals include control results, so that the main control unit 202 converts the 2 / 4 / 8 / 16FSK target encoding format feedback signals into feedback signals in serial port SP / LIN / CAN / Ethernet / USB encoding format, and allows the human-machine interaction unit 205 to allow the staff to view the control results.

[0065] This invention uses a protocol converter 2 to convert data signals of different encoding formats into a unified target encoding format. In the absence of a dedicated communication interface circuit, the electronic controller 3 can convert the data signals output from different hardware interfaces of the communication module 1 into an encoding format that the electronic controller can receive. That is, it is not necessary to configure the electronic controller 3 to receive signals output from different hardware interfaces, and the electronic controller 3 can still be controlled.

[0069] After receiving the communication data signal in the target encoding format, the electronic controller 3 performs software flashing to enable control of the electronic controller 3. The electronic controller 3 sends the control result as a feedback signal in the 2 / 4 / 8 / 16FSK target encoding format to the protocol converter 2.
