Frequently Asked Questions
What is the 37Nm Autonomous Rack System?
37Nm Autonomous Rack System by DCE is a versatile electric steering solution, ideal for small autonomous vehicles like people mover pods and delivery vehicles. It offers up to 37Nm of torque and supports both manual and autonomous control via CAN Bus.
What is included with the 37Nm Autonomous Rack System?
The standard package includes: EPR02 | Powered Rack 37Nm; EPAS18A | Autonomous Ultra ECU; EPAS19 | Ultra Wiring Harness; PNA1141 | 1080 Degree Position Sensor. See above for optional extras where available.
Can the 37Nm Autonomous Rack System be controlled by an autonomous driving stack?
Yes. The 37Nm Autonomous Rack System 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 37Nm Autonomous Rack System available?
The 37Nm Autonomous Rack System is available through Leo Drive in the following region: Turkey. For other regions, please contact Leo Drive.
