What is AMAS?
6
Background
Tactical Vehicle Convoy Issues
Crew fatigue
Rear-end collisions
Operator situational awareness
Response to attack
7
Background
Convoy Active Safety Technology (CAST) Program
US Army and Marine Corps collaboration
$11 million contract award to Lockheed Martin- October 2012
8
Autonomous Vehicle Appliqué System (AMAS)
Designed to enable Autonomous Operation of Military Vehicles
Convoy or independent autonomous operation
Vehicles also fully operational by human operator
9
Supported Vehicle Platforms
M915A3
MTVR
PLS
10
Supported Vehicle Platforms
HEMTT
FMTV
RG-31
What is AMAS?
Fleet Integration Challenges
13
Throttle and Transmission Controls
Independent, but co-operation with a user
Each vehicle variant has a unique throttle/ transmission architecture
Un-powered state of controller has to default to SAFE operation
14
Lighting and Windshield Wiper Controls
Independent control of every light
bulb
Start/Stop of the wipers across all
power modes
15
Brake Controls
Additional valves to operate air
brakes
Supervisor Controls Solution
17
AMAS –System Architecture
18
Onboard Vehicle Controller (OVC)
vehicle agnostic
high-level driving decisions
19
OpenECU M460 Supervisor Controller
Interprets OVC
commands
Commands vehicle-
level systems
20
Power Management Module
Interprets M460
Supervisor commands
Performs body electronic
functions (lights, etc.)

OpenECU Development & Support
31
Initial Development
Pi Engineering Services
Onsite Development
Core Controls Model
Based on OpenECU platform software product
32
Initial Development
M460 Hardware
Commercial Off-the-shelf product
Customized for autonomous and operator mode support.
33
Initial Development
Actia Power Management Module
Commercial Off-the-shelf product
Recommended by Pi Innovo based
on previous experience.
34
Ongoing Development
Lockheed Martin Engineering
Uses OpenECU product from initial development
Configuration Management through OpenECU supported tools
Pi Innovo
provides hardware, or product licenses
35
Ongoing Support / Configuration Management
Controls Development
Performed by Lockheed Martin Engineering
Uses the same OpenECU hardware and software as initial development
Lockheed now manages all software configuration through the OpenECU tools
Limited Pi Innovo support for hardware or development tools.
Thank you!
