Why Choose the Microsteer MGU with Autonomous Control?
Ideal for use as a steering servo when mated to a hydraulic power steering system.
Used on vehicles that still utilize hydraulic power steering and require autonomous & manned control.
Ideal for 12 V DC, very low steering input load vehicles.
MGU is fitted anywhere inline between the steering wheel and rack input pinion.
The input shaft allows manual control as well as autonomous control.
The system can provide up to 37 Nm of steering column torque
CAN Bus control using one of the three following options:
Sending a simulated torque sensor signal,
Sending a +/- duty cycle demand for direct control of the EPAS motor,
Sending heading and gain request for the EPAS motor to steer to.

Frequently Asked Questions
What is the Microsteer MGU with Autonomous Control?
Microsteer MGU with Autonomous Control by DCE is a compact electric power steering solution designed for vehicles with low steering input loads and existing hydraulic systems. Offering up to 37Nm of torque, this system supports both manual and autonomous control via CAN Bus.
What is included with the Microsteer MGU with Autonomous Control?
The standard package includes: EPAS200M19 | Microsteer MGU for EPAS19; EPAS18A | Autonomous Ultra ECU; EPAS19 | Ultra Wiring Harness; PNU0097 | Multi-Turn Steering Angle Kit. See above for optional extras where available.
Can the Microsteer MGU with Autonomous Control be controlled by an autonomous driving stack?
Yes. The Microsteer MGU with Autonomous Control accepts steering commands over CAN Bus, so a drive-by-wire or autonomous driving controller can command it directly while the mechanical input shaft still allows a human driver to steer manually as a fallback.
Where is the Microsteer MGU with Autonomous Control available?
The Microsteer MGU with Autonomous Control is available through Leo Drive in the following region: Turkey. For other regions, please contact Leo Drive.
