Introduction
New Eagle develops and supplies components to Autonomous Systems development. The most common offer is the Raptor line of controllers starting with the GCM196 as a Vehicle Interface Module (VIM), acting as a Drive By Wire (DBW) interface between the AI "Brain" and the vehicle or actuator system.

Drive By Wire Systems
Chrysler Pacifica
The New Eagle Pacifica Drive-by-wire kit is a complete solution for control of the vehicle actuation systems include throttle, braking and steering. The system uses the GCM-196 VIM to interface with the vehicles systems. A computer running the ROS framework along with specially designed nodes communicate with the VIM to provide control commands. For testing of the by-wire system a game controller can be used.
New Eagle provides its ROS libraries at http://wiki.ros.org/pacifica_dbw to help developers create their own application.
Throttle-By-Wire
Throttle control is achieved by intercepting and emulating the signal from the existing throttle pedal on the vehicle using New Eagle's Pedal Emulator module. This method requiring NO additional actuators on the pedal itself and minimizes the latency for control. The system can respond faster than any human due to its 200 Hz control loop. The Pedal Emulator module passes through the driver's pedal input, until activated by the DBW control module. This ensures that accelerator pedal control is always returned to the driver in the event of a fault or emergency stop input.
Steer-By-Wire
Steering control is achieved by interacting with the system’s existing electronic power steering module, requiring NO additional actuators and minimizing the latency for control. Controlling the OEM power steering system makes for a clean interface, simple installation process, and leverages qualified automotive-grade parts to eliminate safety concerns.
Brake-By-Wire
Braking control is achieved by intercepting and emulating the PWM signal from the existing brake pedal on the vehicle, requiring NO additional actuators and minimizing the latency for control. This system leverages both the on-board regen as part of the HEV system and the ABS braking system. In the DBW control software, the emergency stop button & fault actions can be configured to either switch brake control back to the OEM pedal input (if a safety driver is present) or apply the brakes and bring the vehicle to a stop (if no safety driver is present). This makes New Eagle's DBW kit suitable for any level of autonomy.
Shift-By-Wire
Shift control is achieved by intercepting signals from the existing electronic shift actuator to move between Park, Reverse, Neutral, and Drive modes. New Eagle's DBW system can be customized to work with either CAN-based or hardwired electronic shift modules.
Body Control & Sensors
New Eagle's DBW system can also interface with several additional vehicle actuators. On the Pacifica, it can control the following OEM actuators via CAN:
- Turn signals/hazards
- High beam headlights
- Wipers
- Sliding doors & power liftgate.
On other vehicles, New Eagle can customize the DBW system to control these actuators, either via CAN reverse engineering or via connecting DBW VCU outputs directly to the OEM wiring harness.
The Pacifica DBW system can also read data from the following OEM sensors via CAN:
- Wheel speed sensors (with tooth counters)
- 2-axis accelerometer
- Cruise control buttons
- Seatbelt status
- Airbag status
- Door status
- Fuel level
- Ultrasonic park sensors
- Tire pressure
- GPS (optional)
- Adaptive cruise radar (optional).
On other vehicles, New Eagle can customize the DBW system to read these signals, either via CAN reverse engineering or via connecting DBW VCU inputs directly to the OEM wiring harness.
Safety & Reliability
Safety and reliability are critical when doing development for on-the-road vehicles. New Eagle’s drive-by-wire kit was designed with this at the forefront. The kit uses automotive-grade production controllers that ensure high levels of reliability and are deterministic which is key for safety critical applications. The system includes the following safety features:
- Firmware Speed Limits that ensure safe operation during development
- Controllersbring the vehicle to a safe stop if any of the following criteria are met: Loss of heartbeat from AI system Collision warnings from existing on-board sensors Fault Detection from vehicle diagnostics
- Automotive-Grade Ruggedized Hardware (IP68, up to 100°C) that can withstand harsh environmental conditions
- Driver Detection disables the DBW system if the driver actuates the steering wheel, brake pedal, accelerator pedal, or gear shift knob.
