AE410778E Electric power-assisted steering (EPS)

► It includes original vehicle components and diagnostic functionality through a body computer with a low-speed CAN bus. The model is mounted on a mobile stand with wheels, offering hands-on training for technical and vocational education in automotive steering systems.

► Value for Students

● Gain practical understanding of an EPS system in real-world conditions, learning the mechanics of rack-and-pinion steering, McPherson suspension, and electric servomotor-driven steering assistance.

● Analyze and manipulate variables such as vehicle speed, steering effort, and alternator function, providing insight into the dynamic relationship between these systems.

● Understand the interaction between torque sensors and control units, which process torque and position data to regulate steering assistance.

● Study the operational principles of torque and position sensors and how they relay essential information to the control unit, guiding the steering system based on input from the driver.

● Develop proficiency in using diagnostic tools like OBD 16-pin connectors for real-time fault analysis and data monitoring of the EPS system.

● Engage with advanced automotive components, such as the brushless electric motor with permanent magnets and the microprocessor-controlled electronic control unit.

● Observe the impact of steering mode adjustments (“Normal” and “City”) and learn how driving conditions affect power assistance based on vehicle speed.

► Value for Instructors

● Fully functional EPS trainer to demonstrate critical steering system concepts, including how torque and position sensors influence steering dynamics.

● OEM automotive parts ensure realistic, hands-on experience for students, enhancing their technical skills in diagnosing and repairing EPS systems.

● Integrated diagnostic socket with low-speed CAN bus allows educators to teach students how to diagnose issues using professional-grade tools.

● The adjustable steering effort directly on the rack and simulated alternator functions enable educators to replicate real-world conditions and varied driving experiences.
