Control joystick

What is an automotive command joystick?

The command joystick is a centralized control device that serves as the primary intermediary between the driver and the vehicle's infotainment system. Rather than interacting directly with a touchscreen, the driver manipulates this physical controller located on the center console. Inspired by aerospace and video game interfaces, it has been adapted for the automotive industry to offer a safer and more ergonomic method of control while driving. Undoubtedly, the most iconic system is BMW's iDrive controller, a pioneer of the genre since the early 2000s. Interaction is based on simple and intuitive actions:

• Rotation: To scroll vertically through menus or zoom in on the navigation map.
• Push (click): To select an item or confirm an action.
• Tilt: To move in the four or eight cardinal directions, thereby navigating through menu grids or across the map.

Some more advanced models also integrate a touch surface on top of the joystick, allowing for handwritten character input (for a GPS address, for example) or swipe gestures.

Performance and Ergonomic Benefits

The "Performance" category is not limited to engine power; it also encompasses the efficiency of the interface between the driver and their machine. The command joystick excels in this area.

Its main advantage is safety. Thanks to its physical feedback and fixed position, the driver develops muscle memory. After a short adaptation period, they can navigate complex menus without taking their eyes off the road—a major asset compared to a touchscreen, which requires constant visual attention to aim for the right icon. On a rough road or during dynamic driving, the stability offered by the joystick ensures a precision that touchscreens cannot match. Furthermore, it is often surrounded by physical shortcut buttons (Navigation, Media, Radio, Phone), providing instant access to the most frequently used functions, further optimizing efficiency and reducing distractions.

Joystick, rotary dial, trackpad: what are the differences?

The command joystick is part of a family of physical controllers, each with its own specific features:

• The rotary dial: Simpler, it is often limited to rotation and pressing. It is the core of many systems, but it is less versatile than the joystick for multidirectional navigation.
• The central trackpad: Popularized by Mercedes-Benz or Lexus, it offers a touch-sensitive surface that recognizes gestures and handwriting. However, it can lack precision while driving, as the hand lacks a stable resting point.
• The touchscreen: The most direct approach, but it leaves fingerprints and forces the driver to look away from the road.

The command joystick often combines the best of all worlds: the rotary precision of a dial and the directional navigation of a pad, all with the physical confirmation of a click.

Which manufacturers favor this technology?

The command joystick is a signature of premium automakers who invest heavily in the ergonomics of their cabins. It can be found notably at:

• BMW: With its famous iDrive controller, the industry benchmark for generations.
• Audi: Although increasingly turning toward dual touchscreens with haptic feedback, their older MMI systems used a highly evolved dial akin to a joystick.
• Mazda: With its HMI Commander system, the Japanese brand makes touch-free ergonomics a major selling point for safety.
• Genesis and Lexus: These luxury brands also use central controllers to operate their interfaces, highlighting their commitment to a less distracting driving experience.

In conclusion, the command joystick is much more than a simple gadget. It is a philosophical choice in favor of safety, ergonomics, and a high-performing driving experience where the driver remains in control of their technological environment without compromising their concentration on the essential: the road.
