When the second electrical architecture is tested, interface 1 and interface 2 are disconnected, interface 1 and interface 3 are connected, and the ECU1 module is connected with CAN1a line 103, conforming to the wiring of the second electrical architecture.

When the second electrical architecture is tested, the on-off switch k1 is turned off and the on-off switch k2 is turned on, so that the ECU1 module is connected with the CAN1a line 103. The connection relation between the ECUi module 20 and the CAN line CAN be switched between the first electrical architecture and the second electrical architecture by controlling the on-off of the on-off switch k, so that the operation is convenient, and the wiring is stable and reliable. Preferably, the connection terminal 301 may be a phoenix connection terminal 301, so that the connection is convenient, and the first switch 30 may be formed by connecting two phoenix connection terminals 301.

Example 2

In addition to the difference in CAN lines that part of the ecu i module 20 is connected between the first electrical architecture and the second electrical architecture, the ecu i 'module 40 (i=1, 2,3, … …) may be added to the second electrical architecture, and the added ecu i' module 40 is not connected to the CAN1 line 101 or CAN2 line 102 in the first electrical architecture. The ecu 'modules 40 may also be reduced in the second electrical architecture, the reduced ecu' modules 40 being connected to either CAN1 line 101 or CAN2 line 102 in the first electrical architecture, and not in the second electrical architecture. The second electrical architecture newly added or subtracted ecu i' module 40 may be connected to or disconnected from either CAN1 line 101 or CAN2 line 102 by a second switch 50. The second switch 50 has an interface 4 and an interface 5, the interface 4 is used for connecting the ecu i 'module 40, the interface 5 is used for connecting the CAN1 line 101 or the CAN2 line 102, and the on-off of the ecu i' module 40 and the CAN1 line 101 or the CAN2 line 102 CAN be controlled by the on-off of the interface 4 and the interface 5. As shown in fig. 1 for the ECU1' module, when the second electrical architecture has the ECU1' module and the first electrical architecture is not, the connection of the ECU1' module to the CAN1 line 101 is disconnected by disconnecting the interface 4 and the interface 5 when testing the first electrical architecture; when the second electrical architecture is tested, the interface 4 and the interface 5 are communicated, and the ECU1' module and the CAN1 line 101 are communicated. When the first electrical architecture has an ECU1 'module and the second electrical architecture is absent, the interface 4 and the interface 5 are connected when the first electrical architecture is tested, and the ECU1' module is connected with the CAN1 line 101; disconnecting interface 4 and interface 5 when testing the second electrical architecture disconnects the ECU1' module from CAN1 line 101.

Preferably, as shown in fig. 3, the second switch 50 is a connection terminal 301; one of the interfaces a and b is used to connect with the ecu i' module 40, and one of the interfaces c and d is used to connect with the CAN1 line 101 or the CAN2 line 102. Taking the ECU1 'module as an example, the interface a of the connection terminal 301 is connected to the ECU1' module, and the interface c of the connection terminal 301 is connected to the CAN1 line 101, so that the interface a is the interface 4 of the second switch 50, and the interface c is the interface 5 of the second switch 50. When the second electrical architecture has the ECU1 'module and the first electrical architecture is not, the connection of the ECU1' module and the CAN1 line 101 is disconnected by disconnecting the on-off switch k when the first electrical architecture is tested; when the second electrical architecture is tested, the on-off switch k is connected, and the ECU1' module is connected with the CAN1 line 101. When the first electrical architecture has the ECU1 'module and the second electrical architecture is not, the on-off switch k is communicated when the first electrical architecture is tested, and the ECU1' module is communicated with the CAN1 line 101; opening the on-off switch k when testing the second electrical architecture disconnects the ECU1' module from the CAN1 line 101. Preferably, the second switch 50 may also use a phoenix connection terminal 301.

Corresponding to the newly added ecu i' module 40 of the second electrical architecture, the on-off switch k may be marked (two) to indicate that the on-off switch k is connected for the second electrical architecture; the on-off switch k is opened for the first electrical architecture. The ecu i' module 40 corresponding to the reduction of the second electrical architecture may be marked with (one) on the on-off switch k, indicating that the on-off switch k is on for the first electrical architecture; the on-off switch k is opened for the second electrical architecture.

Example 3

Part of the ecu i module 20 is connected to one of the CAN1 line 101 or CAN2 line 102 in the first electrical architecture and still connected to the other of the CAN1 line 101 or CAN2 line 102 of the first electrical architecture in the second electrical architecture, the ecu i module 20 is not connected to the newly added CAN1a line 103 of the second electrical architecture, but the CAN line connected to the first electrical architecture and the CAN line connected to the second electrical architecture are still modified. It is also possible for these ecu i modules 20 to be switched between different CAN lines of the first electrical architecture by the first switch 30. As shown in fig. 1, the interface 1 of the first switch 30 is used for connecting with the ECU2 module, the interface 2 is used for connecting with the CAN1 line 101, and the interface 3 is used for connecting with the CAN2 line 102. For example, the ECU2 module is connected to the CAN1 line 101 in the first electrical architecture, connected to the CAN2 line 102 in the second electrical architecture, and connected to the CAN1 line 101 by connecting the interface 1 and the interface 2 and disconnecting the interface 1 and the interface 3 when testing the first electrical architecture. When the interface 1 and the interface 2 are disconnected and the interface 1 and the interface 3 are communicated during the test of the second electrical architecture, the ECU2 module is connected with the CAN2 line 102.

Example 4

The test system further comprises an ECU3 module and an ECU4 module, wherein the ECU3 module and the ECU4 module are connected to the CAN1 line 101 in a first electrical architecture and connected to the same one of the CAN2 line 102 or the CAN1a line 103 in a second electrical architecture; or the ECU3 module and the ECU4 module are both connected to the CAN2 line 102 in the first electrical architecture and to the CAN1a line 103 in the second electrical architecture, i.e. the CAN lines to which the ECU3 module and the ECU4 module are connected in the first electrical architecture are identical and the CAN lines to which the second electrical architecture is connected are also identical.

The interface c of the 1# terminal 301 is connected to the

CAN1 line

101,2# terminal 301 and the interface c is connected to the CAN1a line 103. When the first electrical architecture is tested, the on-off switch k1 is connected, the on-off switch k2 is disconnected, the ECU3 module is connected to the CAN1 line 101 through the interface a of the 1# wiring terminal 301→the interface c of the 1# wiring terminal 301, the ECU4 module is connected to the CAN1 line 101 through the interface b of the 2# wiring terminal 301→the interface a of the 1# wiring terminal 301→the interface c of the 1# wiring terminal 301, and thus the ECU3 module and the ECU4 module CAN be simultaneously connected to the CAN1 line 101 through the on-off operation of the on-off switch k1 and the on-off switch k2 of one first switcher 30. Likewise, when testing the second electrical architecture, opening the on-off switch k1 and closing the on-off switch k2 may enable the ECU3 module and the ECU4 module to be simultaneously connected to the CAN1a line 103.
