CRH Steering Test System
Steering Test System with HIL Simulation (NEW)
This system utilizes our own quiet and highly responsive linear servo actuator. It is ideal for evaluating HILS response and noise, both common challenges for conventional hydraulic servos. This system is designed to safely assess the feel and fail-safes of the steering assembly without the need for a vehicle. It can also act as an evaluation system for steering stability when integrated with DiM.
