Specialised vehicle HMI – It’s about intuition, location and feel

User interface is an extremely important aspect of any vehicle experience, especially those which have been extensively modified with extras - hydraulic lifting controls, sirens, light bars, central input devices, and security measures.

How to control these additional functions within the existing vehicle interior, without interfering with the driver’s view or interior ergonomics, poses a real challenge. Overall, there must be an intuitive cockpit HMI (Human Machine Interface) where everything is well within the driver’s reach and view.  

EAO specialises in bespoke, built-in panel solutions to optimally present information within the existing dashboard and ‘centre stack’. Typically we utilise a mix of technologies which might include a touch screen or display, membrane keypad, discreet pushbuttons and emergency-stop functions built into a protective housing and connected through an appropriate serial bus (CAN/J1939) to simplify wiring and communications.

EAO understands that specialist vehicles may require updating and adaptation so we design switch panels with optimum flexibility in mind. Modular switching components can be plugged into the panel and locked firmly in place, simplifying both assembly and maintenance. This arrangement allows vehicle builders to store components separately and configure them during final assembly to meet end-user needs.
