Problems solved by technology
However, due to the differences in the hard wire interfaces of different ECUs and the limitations of the I / O board interface types, it is difficult to automate the interface configuration during the construction of the test platform, and the wiring harness cannot be used universally, which makes the test platform construction process take up a lot of time. Time requirements are limited, and platform construction takes up a lot of time, resulting in compressed test case execution time
In order to solve this problem, in the related art, a signal transfer device such as a signal configuration box (Break-Out-Box, BOB, or signal transfer box, etc.) is connected in series between the I / O board and the ECU to realize hardware-in-the-loop Test the connection between the system and the ECU, but the signal configuration box in the related art has problems such as poor versatility, fixed interface configuration and unable to realize automatic configuration, etc.

The invention relates to a signal switching control method, a signal switching device, a test system and a platform. The device is characterized in that one of a plurality of switches is connected in series between the first end of each first terminal in a first terminal group and the first end of each second terminal in a second terminal group; a control module determines a plurality of target switches needing to be turned on from the plurality of switches according to the device connection setting, and sends a control signal for turning on the plurality of target switches to a driving circuit; and the driving circuit is connected with the plurality of switches and the control module, and drives the plurality of target switches to be turned on according to the received control signal, so that a signal path between the first terminal and the second terminal connected with each target switch is conducted. The mapping relation between the terminals can be customized, automatically, simply, efficiently and accurately configured according to actual needs, the universality of the device is good, and the expansion capacity of the number of the terminals is high.
Description
technical field [0001] The present application relates to the technical field of test equipment, in particular to a signal transfer control method, a signal transfer device, a test system and a platform. Background technique [0002] Hardware-In-Loop (HIL) testing of devices such as Electronic Control Units (ECUs) can significantly reduce development time and costs. In the hardware-in-the-loop test, it is necessary to configure the interface and make the wiring harness according to the hard-wire interface definition of the ECU and the I / O board interface type of the hardware-in-the-loop test system, so that the tested ECU can be connected to the hardware-in-the-loop test system. Complete the construction of the test platform and carry out subsequent tests. However, due to the differences in the hard wire interfaces of different ECUs and the limitations of the I / O board interface types, it is difficult to automate the interface configuration during the construction of the te...
