37Nm Autonomous Rack System
Our electric steering rack can be used for manual (when optional EPAS16 CTS is added) or autonomous applications and is designed to replace the original steering rack.
- Ideal for small autonomous vehicles such as people mover pods and delivery vehicles.
- Complete powered rack to replace the existing manual steering rack.
- Input shaft allows manual as well as autonomous control.
- System can provide up to 37Nm / 26.5ft.lb of torque to the rack pinion.
- 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.
