As defense vehicles grow more connected and software-defined, the need for intelligent, rugged, and flexible control systems is more critical than ever. Modern tactical platforms are evolving to feature advanced digital backbones, particularly those using CAN-based (Controller Area Network) architectures, to support seamless interoperability, simplify wiring, and improve maintainability in the field.
Why CAN Bus in Tactical Vehicles?
Originally developed for automotive systems, CAN bus has become a standard across modern defense vehicles due to its efficiency and resilience. Its popularity stems from key benefits:
-
Reduced cabling complexity: Multiple devices communicate on a shared data bus, minimizing wiring weight and clutter.
-
Enhanced diagnostics: CAN protocols like J1939 support onboard diagnostics and fault reporting.
-
Real-time data transfer: Operators receive system status instantly, improving situational awareness and reaction time.
-
Scalable integration: CAN-based systems are adaptable across legacy and next-generation vehicle architectures.
Grayhill’s CAN-Based HMI Solutions for Defense
Grayhill offers a portfolio of ruggedized, military-grade HMI components built for CAN bus integration. These include:
-
CAN-enabled keypads with embedded diagnostics and plug-and-play architecture, simplifying installation and field service. Designed with NVIS-compatible backlighting and sealed to withstand immersion, these keypads meet MIL-STD-810 and MIL-STD-1472 environmental and ergonomic standards.
-
Rugged rotary encoders and joystick modules for precise control, configured as part of modular HMI panels to fit platform-specific layouts.
-
Daylight-readable displays with integrated CAN interfaces, delivering real-time feedback and control for mission systems.
These products have been field-proven in platforms such as the JLTV and MRAP, where harsh operating environments demand exceptional reliability. From -51 °C cold starts to electromagnetic interference shielding, Grayhill’s HMI components are qualified for the real world of defense mobility.
