Description

Because each ECU has different design requirements, circuit structure, interface structure and many other aspects, different specifications of adapters need to be used when testing different ECUs. In the case that up to dozens (for example, 70 or more) ECUs need to be deployed in the entire vehicle network, the development and testing process requires frequent replacement of adapters of different specifications, which is not only cumbersome, time-consuming and labor-intensive, but also affects the efficiency of ECU development and testing, and brings great inconvenience to the development and testing of vehicle networks.

[0029] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the accompanying drawings and specific embodiments are only exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0030] like Figures 1 to 4As shown, an embodiment of the present invention discloses an ECU signal switching device, including a box body 1, a first socket group, a second socket group and at least one toggle wiring assembly 4 are arranged on the box body 1, the first socket group includes at least one access socket 2, the second socket group includes at least one access socket 3, and each toggle wiring assembly 4 is correspondingly connected to an access socket 2 and a contact socket 3. The toggle wiring assembly includes a toggle block 41 and a toggle slot 42, the toggle block 41 can be movably engaged in the toggle slot 42, the toggle block 41 is provided with a first interface 43 and a second interface 44, the first interface 43 is connected to the access socket 2, the second interface 44 is connected to the access socket 3, the toggle block 41 is provided with a second contact piece 6, the toggle slot 42 is provided with a first contact piece 5, and the first contact piece 5 and the second contact piece 6 are in corresponding positions. The first contact piece 5 can be arranged at any position on the inner side wall of the toggle slot 42, as long as the first contact piece 5 and the second contact piece 6 can contact after the toggle block 41 moves.

[0031] The first contact piece 5 is connected to the input socket 2, and the second contact piece 6 is connected to the output socket 3. When the toggle block 41 moves to the first position, the first contact piece 5 and the second contact piece 6 are in contact to form an electrical connection. When the toggle block 41 leaves the first position, the first contact piece 5 and the second contact piece 6 are separated. It should be noted that the first position is different according to the different positions of the first contact piece 5 and the second contact piece 6.

[0032] In the prior art, only signal switching or fault simulation can be performed separately. The embodiment of the device of the present invention can conveniently switch between the signal switching mode and the fault simulation mode by providing a toggle type wiring assembly 4. By providing a first interface 43 and a second interface 44 on the toggle block 41, an external fault simulator can be connected to perform fault simulation operations, thereby eliminating the need to operate the vehicle sensors and components themselves, which is efficient and convenient.

[0033] The embodiment of the present invention also discloses an operation method of the aforementioned ECU signal switching device, such as Figure 6 As shown, it includes: connecting the ECU end to the access socket and connecting the vehicle end to the output socket; when ECU signal transfer is required, moving the toggle block to the first position; when fault simulation is required, moving the toggle block away from the first position, and performing fault simulation operations through the first interface and the second interface.

[0035] In the prior art, numbers are usually marked on each interface for correspondence, which requires that the corresponding interface needs to be found during signal switching, and the corresponding interface needs to be found based on the numbers during fault simulation, which is inconvenient. Therefore, an embodiment of the device of the present invention also includes a guide component, which includes a first indicator light 9 and a second indicator light 10.

The fault simulation indicator light 11 is connected in parallel to the fault simulation branch, and the signal transfer indicator light 12 is connected in parallel to the signal transfer branch. When the signal transfer branch is connected, the signal transfer indicator light 12 lights up; when the fault simulation branch is connected, the fault simulation indicator light 11 lights up.

[0037] In a possible embodiment, the second contact piece 6 is disposed on any end surface of the toggle block 41 in the toggle slot 42 along the movable direction, and the first contact piece 5 is disposed on the inner side wall of the toggle slot 42 close to the first contact piece 5, so that the operator can more accurately toggle the toggle block 41 to the top of the toggle slot 42. Figure 4 As shown, at this time, the toggle block 41 reaches the first position, and the first contact piece 5 is in electrical contact with the second contact piece 6. Correspondingly, the signal transfer indicator light 12 can be set on the side of the box body 1 close to the first position, and the fault simulation indicator light 11 can be set on the side of the box body 1 away from the first position, so that the current mode can be intuitively known.

[0038] When connecting different types of ECUs to the vehicle, you may also need to set a certain terminal resistance. Figure 5 As shown, in a possible embodiment, the device further includes a load circuit 13, which is connected in series to the access bus 7 or the output bus 8, and includes a non-load branch and a loaded branch, which are connected to the access bus 7 or the output bus 8 by means of a selection switch. In this way, when a terminal resistor needs to be connected, the loaded branch can be connected through the selection switch.

[0039] Further, in order to achieve load regulation with different precisions, the load circuit 13 can be set to include a coarse adjustment circuit and a fine adjustment circuit, and the coarse adjustment circuit and the fine adjustment circuit are connected in series to the access bus 7 or the output bus 8. Specifically, the coarse adjustment circuit includes a first no-load branch 14 and a first load branch 15, and the first no-load branch 14 and the first load branch 15 are connected in parallel by means of a first selection switch 18. The fine adjustment resistor includes a second no-load branch 16 and a second load branch 17, and the second no-load branch 16 and the second load branch 17 are connected in parallel by means of a second selection switch 19. A coarse adjustment sliding rheostat 20 is provided on the first load branch 15, and a fine adjustment sliding rheostat 21 is provided on the second load branch 17.
