Goepel Electronic introduced the OsCAR light test system for car seats. It may be used to test each car seat of each manufacturer and is configurable for special UUTs (units under test). Test of embedded ECUs may be done via CAN, LIN or K-Line interfaces.
THE PC-BASED SYSTEM, OPERATED PER TOUCH SCREEN, allows measurement of all electrical characteristic values (resistance, current, voltage). It fulfills continuity and isolation testing of wiring harness and checks feature characteristics (e.g. seat barcode or data base). Seat occupancy is recognizable. While ECU test via CAN coding and parameterization, data comparison as well as quiescent current measuring are possible.
Using the Progress test sequencer software the test run generation is possible. Macro libraries are already available. The tester also may be utilized offline for programming and parameterization tasks, or to simulate test runs and compare the results with real tests at a later point in time. It also allows parallel test of installed electronic control units (ECU). Compared to sequential test runs, the number of required test systems in production may be minimized, which leads to test time and test cost optimizations.
The system may be extended to support multi-contour seat tests as well as structure-borne sound analyses, pneumatics tests, inspection of optical characteristics or testing of architectural equipment for double-seats. It enables parameterization of components in car seats. Generation of test programs and implementation of pre-configurations is possible. Each seat’s data are entered into the test system software whereupon the seat type is automatically identified.
The company focused on automotive functional test solutions also introduced the top hat rail Hub4x module for multiplexing of CAN interfaces. The device allow for data exchange with several CAN-connected test objects. It is suited for centralized test scenarios (e.g. parallel tests or continuous operation tests), as the module may replace several single interfaces. Utilizing the module for ECU-screenings regarding the environmental influences is possible as well. The module includes a master and a slave unit. Physical CAN interface features may be varied via pluggable transceivers. Via the master unit the connected modules may be parameterized as router or gateways. Thus, master-unit coded CAN telegrams are decoded by the module and forwarded to the underlying testees. Reverse conversation is also possible using the routing functions. Additionally, the device offers inputs and outputs for e.g. synchronization or trigger purposes. A USB interface allows for e.g. software updates.
