Raptor VeeCAN 800

The VeeCAN 800 is a 7" fully waterproof resistive touchscreen display. It features a WVGA 800 x 480 TFT LCD color display and two USB ports (one rear and one front accessible). The VeeCAN 800 also supports 14 analog inputs, four digital inputs, eight outputs, two CAN connections, as well as an Ethernet connection.

Pedal Emulator

The New Eagle PWM to Analog Converter converts 3 separate channels of PWM signals to proportional 0-5V analog signals. The converter is especially useful when paired with control modules with PWM outputs, but no 0-5V analog outputs. This device is very useful as a pedal emulator.

Sensors

Mounting & Packaging

The DBW kit hardware is scalable and can be designed to fit in the rear storage compartment of the vehicle (if it exists). It is based on a rack-mount design and bolts directly to the floor. The top tray encloses the rack and allows for the driver to continue to use the rear of the vehicle for cargo storage. The rack includes extra space for mounting additional autonomous hardware. An example AI computer is shown in the figure below, which can be replaced with a different form factor if needed.

Power & Thermal Management

The power system is scalable and can be configured to match your sensor and computing needs. The OEM 12V charging system can spare up to 1000W of continuous power for autonomous computing hardware. New Eagle also recommends a 2nd lead acid battery to stabilize the system under peak vehicle electrical loads. The DBW mounting rack also has space reserved for an optional pure sinewave inverter capable of outputting 500W continuous and 2KW peak output to power 110V AC systems. The power system might also include CAN-based relay control modules as shown in the system architecture diagram (Figure 1) that allow control of 10 channels each with a maximum of 20 amps for a total of 1KW of maximum power output.

The mounting rack also has space reserved for a liquid-to-air heat exchanger, if desired. This heat exchanger can reject heat from most power electronic systems without the need for a fan, making the system very quiet.

Please discuss your power system needs with the New Eagle team

Autonomous Control Interface: ROS-M

ROS (Robot Operating System) provides libraries and tools to help software developers create robot applications. It provides hardware abstraction, device drivers, libraries, visualizers, message-passing, package management, and more. ROS is licensed under an open source, BSD license. New Eagle has published a ROS module to integrate our DBW controller with any ROS system. This module includes SocketCAN drivers for use with a variety of PC CAN adapters.

For demonstration purposes, this module also includes everything needed to control the vehicle via a USB game controller connected to a PC. This allows DBW system validation to be completed even if the full autonomous control software is not yet available.

New Eagle's ROS source code can be found on the ROS wiki here: Pacifica-DBW ROS interface

-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 to interface with the vehicles systems.  A computer running the ROS framework along with specially designed nodes communicate with the DBW control module 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 http://wiki.ros.org/pacifica_dbw] to help developers create their own application.

-==== Throttle-By-Wire ====
+{| class="wikitable" style="text-align: center;" cellpadding = "5"
-Throttle control is achieved by intercepting and emulating the signal from the existing throttle pedal on the vehicle using New Eagle's [https://store.neweagle.net/product/pwm-to-analog-converter-w-24-pin-header/ 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 ====
+== Power Management ==
-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 ====
+=== 12V CAN-Based Power Distribution ===
-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 ====
+=== 1 KW DC-DC Converter ===
-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 ====
+== 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
-*'''Controllers bring 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 Rugged 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.
-The optional safety features are:
-*'''Redundant VCU controllers''' that work in coordination to bring vehicle to a safe stop if there is a checksum disagreement between them
-*'''Trajectory Buffer''' that allows vehicle to follow last known safe route while bringing vehicle to a safe stop
-*'''Redundant Brake Controls''' that ensure vehicle will stop in emergency situations
