Product: HIL System Testing for ABS/ESP ECU, Pump & Valve Systems

Client Challenge:
The client required HIL-based system testing support for heavy-duty vehicle braking systems, including configuration of dSpace environments, vehicle dynamics parameterization, and identification of sensor- and calibration-related issues affecting ABS/ESP behavior.

RSB Solution:

• Configured HIL environments for heavy vehicle system testing using dSpace hardware
• Prepared and executed test scenarios and test suites for ABS/ESP ECU systems
• Modeled steering angle, yaw rate, wheel speed, and pressure control valve sensor behavior within VOES and Control Desk environments
• Investigated spontaneous errors related to wheel speed sensor failures
• Analyzed inaccurate steering angle sensor timing measurements
• Updated wheel speed models to better reflect actual vehicle sensor resolution and boundary conditions
• Identified calibration and software parameter issues related to wheel difference ratio behavior
• Updated vehicle dynamic models and parameterization to improve real-life system representation and pump pressure behavior

Delivered Results:
The project delivered updated HIL models, corrected software parameterization, and improved vehicle dynamics representation for ABS/ESP system-level testing activities.

Client Value:
The client gained structured HIL validation support that improved accuracy of vehicle behavior simulation, enabled faster identification of calibration-related issues, and increased reliability of ABS/ESP testing activities for heavy-duty vehicles.
