Synapse: APEM’s adaptive programmable joystick concept redefines vehicle control
Date: 16/10/2025
In the field of vehicle control- ergonomics, precision and safety are essential. Construction machinery, agricultural equipment, and material-handling vehicles all place increasing demands on human-machine interfaces (HMIs), while striving to streamline cabin design. At the same time, operators increasingly expect HMIs to be more intuitive and easy to use, reducing the learning curve and enhancing comfort during operation.
With its Synapse programmable joystick concept, APEM introduces a groundbreaking and field-tested innovation: a real-time adaptive joystick that sets a new benchmark in vehicle control. Thanks to haptic feedback and enhanced feel, operators can build greater trust in the machine, improve efficiency, and extend machinery lifetime.
One joystick, infinite possibilities
Traditionally, OEMs and fleet managers juggle multiple joystick references to meet different applications. Synapse eliminates this complexity by delivering a universal joystick base adaptable across multiple vehicles, attachments, and use cases.
Reduced inventory management: one consolidated part number instead of many.
Simplified cabin design: merge main and auxiliary joystick functions into a single integrated solution.
Future-proofing: update joystick capabilities via software rather than hardware changes.
Real-time adaptation for every operator and environment
Synapse is adaptive by design. Its programmable base adjusts in real time to:
Varying environments: rough terrain, high-noise zones, or cabinless autonomous platforms.
Use cases: the joystick’s behavior adapts to each application (single axis, detents, force feedback, friction brake, vibration, freedom of movement...).
Operator preferences: customizable ergonomics to reduce strain and prevent musculoskeletal disorders.
Attachments and tools: optimized haptic patterns for efficiency and precision when switching implements.
Enhanced operator safety and machine integrity with haptic intelligence
Safety is central to Synapse’s design. The joystick introduces context-aware haptic feedback, enabling operators to literally feel the machine’s limits.
Force feedback: resistance increases when loads reach critical thresholds.
Virtual walls: joystick blocks movement before entering unsafe zones.
Detents and vibration alerts: tactile warnings prevent overshooting, tipping, or collision risks.
Ready for the future of mobility
Emerging trends such as autonomous driving, teleoperation, and steer-by-wire demand HMIs that go beyond traditional controls. Synapse is designed for this future:
Operate vehicles without steering wheels—drive directly with the joystick.
Manage multiple platforms from a single adaptive control point.
Benefit from continuous software upgrades, ensuring long-term relevance.
