Fig. 2 is a schematic diagram of an alternative communication connection between a diagnostic device and a domain controller according to an embodiment of the present invention, where the domain controller may be isolated from each other, i.e. only the processing chip 1 is in a DOIP communication connection with the diagnostic device, and the other processing chips, i.e. the processing chip 2, the processing chip 3 and the processing chip 4 are in a communication connection with the processing chip 1, as shown in fig. 2. As can be seen from fig. 2, the processing chip 1 is a first processing chip, and the processing chip 2, the processing chip 3, and the processing chip 4 are second processing chips.
It should be noted that the diagnostic apparatus only establishes a DOIP link with the processing chip 1. The processing chip 1 may exist as a gateway, i.e. the processing chip 1 may send diagnostic service protocol (Unified Diagnostic Services, UDS) messages to the processing chips 2, 3, 4, enabling software flashing of the processing chips 2, 3, 4. From the outside of the domain controller, the diagnostic apparatus can realize software flashing of 4 chips of the whole domain controller by only sending a UDS message to the processing chip 1. And, the domain controller adopts a parallel brushing implementation manner, that is, the processing chip 2 does not need to wait for the brushing. The processing chip 3 is restarted to be refreshed, and after the processing chip 1 receives the software program installation package (namely the software refreshing data package) corresponding to the processing chip from the diagnostic apparatus, the refreshing function can be synchronously realized for a plurality of corresponding chips.
It should be noted that, the number of the second processing chips in fig. 2 is not limited to the processing chips 2-4, and in this embodiment, only the processing chips 2-4 are taken as an example for illustration, and the number of the second processing chips may be other, and is not limited in this embodiment.

It should be noted that, in this embodiment, the diagnostic apparatus address is SA-TEST, and the processing chips 2, 3, and 4 cannot establish additional DOIP links with the processing chip 1. Therefore, in this embodiment, an SA address is set up for the processing chip 1 alone by adding an SA address, which is abbreviated as SA-SOC1 in this embodiment. Forming independent DOIP links for SA-SOC1 and processing chips 2, 3, 4. The parallel brushing efficiency can be improved by establishing communication connection through the two diagnostic instrument addresses.
In the fault diagnosis scene, after the domain controller is connected with the diagnostic instrument, the diagnostic instrument can automatically establish DOIP links with all processing chips in the domain controller (the DOIP links are established by the diagnostic instrument address SA and the processing chip address TA, and a unique link is formed after binding), and at the moment, the diagnostic instrument can directly perform fault diagnosis on all the processing chips.
The software refreshing method of the domain controller of the embodiment adopts a whole-board refreshing mode and a parallel refreshing mode. After the whole-board flush is adopted (i.e. the domain controller is regarded as a whole), the diagnostic apparatus only needs to establish a DOIP link with one node, and then software flush is started. Greatly improves the software refreshing speed of the controller and accelerates the production and manufacturing beats of factories. The more chips on the controller, the more significant the efficiency improvement. If 5 chips are arranged on the controller, the efficiency is improved to be 5 times of the original efficiency, and the production efficiency is obviously improved. After the whole board is adopted for brush writing, the development of diagnostic instruments of original equipment manufacturers (Original Equipment Manufacturer, OEM) is simplified, the diagnostic instrument programs of 5 chips are originally developed, only one diagnostic instrument program of a domain controller is required to be developed at present, and the development efficiency in the development process is improved exponentially.
