System Test of Body ECU

Scope/challenges

Design and Implement a cost-effective test environment for Body and comfort functionalities in the vehicle. The system allows full- and semi-automatic test execution and offer a remote interface for configuration, calibration and test campaign management.

Solution/realization

• Developed a HiL (Hardware in the Loop) test automation solution which cover all needed bus systems and provided test HW digital/analog inputs/outputs of the DUT (Device Under Test).

• Resistance decade for simulation of a sensor
• Measurements of outputs signals, voltage, current, PWM measurements
• Simulate the Battery, voltage range, current measurement
• Electronic load for actuators simulation

Impact/ business value/results

• Early testing concept, fast test results delivery
• Accelerating test process via simulation
• Ease of access to information about test results and reporting
• Easy modification of test parameters
• Highly configurable environment allows flexible adaptation to the customer change requests
• High quality of test through an intelligent testcase generation, execution and pre-analysis procedure
