μLC Test System
The compact hardware-in-the-loop test system for simulation and quality assurance
The new and modern hardware-in-the-loop test system μLC Test System is suitable for mobile application, measuring a compact 17 cm x 11 cm x 6 cm. Initial test setup typically takes under ten minutes, since the system allows for a simple test setup. It is a compact open-loop test system for quality assurance of control unit development and combines the simulation of all typical automotive sensors and communication protocols in one unit. Its interface is userfriendly and enables an easy operation and evaluation. The μLC Test System is especially used for automotive control units with typical interfaces for sensors and bus systems such as analogue/digital inputs and outputs, PWM signals, SENT, LIN, CAN and speed sensors.

Flexible possibilities for test automation
Since the µLC Test System is flexible and efficient with minimal cost, each individual control unit project can have its own test station to provide the best possible support to automated testing. The µLC Test System provides the possibility of a complete automation through Lua scripts and an application programming interface (API). This API fits the existing control software and offers both a graphic interface and the opportunity to operate the µLC Test System. Thanks to its open software interfaces, the test system can also be integrated into pre-existing test infrastructure such as Trace Tronic GmbH’s ECU Test. As a result, this sort of test system allows for continuous integration in software development, so as to keep on collating the modifications of different developers.

Example of application for the µLC Test System
The µLC Test System stimulates the control unit with simulated sensor signals. In case of an engine control unit, e.g. crankshafts and camshafts, accelerator pedals (analogue or SENT), combined sensor e.g. temperature – oil pressure sensor (complex PWM). It facilitates the measurement of both the control unit signals (analogue, PWM, buses) and internal variables of the control unit e.g. using calibration software.
Examples of application

Review of flashing process
Review of core functions of the control unit
Functional testing of individual functional parts within the software
E.g. checking whether cooling is activated at a certain temperature

Control of diagnose – tester communication
The symbiosis of hardware and software – µLC Test System and MicroLC Software
Bosch Motorsport provides the µLC Test System, including the hardware and control software (MicroLC Software), and its maintenance by regular software updates and e-mail support. The MicroLC Software is finely adapted to the µLC Test System and guarantees a fast test arrangement and results, since it is ready to use at any time. If required we offer additional services for an expansion of the hardware (e.g. additional interfaces) and of the control software by implementing new functions. Further a connection to existing customer solutions, an implementation of automations and the development of test cases is served.
