Electric Power-assisted Steering Module Test System

Often, an ECU or body control module requires the simulation of the surrounding conditions to effectiviely test the device.

In the case of this 42-volt Electric PAS (EPAS)system, test fixturing was designed that incorporated the various steering components, including a Hysterisis Brake that simulated the resistive load of the steering wheel.

The actual device under test (DUT) was the electronic body module (not shown and remoted mounted in a climatic oven) that controlled the steering system.

The peripheral equipment stimulated the module using real vehicle components.
