On July 8, 2024, AUDIOWELL officially launched its self-developed haptic solid-state button solution for steering wheel applications at electronica China 2024, which received widespread attention and was appreciated by many industry experts after experiencing the solution's functionality and excellent performance.
Automotive haptic solid-state button solution for steering wheels
The haptic solid-state button solution for steering wheel released this time is based on the haptic feedback actuator as the core component, using the piezoelectric haptic feedback technology to reproduce the real touch sensation for the steering wheel buttons through the physical principle of positive and negative piezoelectric effect.When the haptic feedback actuator is loaded with a drive voltage, it creates a mechanical deformation that induces a limited range of vibrations, and the user can feel the actual vibration from the solid-state button.This solution, which uses high-resolution localized haptic buttons instead of the old mechanical button interface, reinvents the interaction of the steering wheel edge buttons.
Multi-position adjustment of vibration
As shown in the demo, the tactile solid-state button solution applied in the steering wheel is more humane than traditional mechanical buttons, and it can provide intuitive adjustment of various parameters such as duration, amplitude and frequency of vibration feedback, with no less than six gears for each parameter. Users can choose a preferred vibration effect to use after the experience, in this way, a programme can be adapted to the needs of people with different tactile sensitivity.
Interaction methods can be adjusted with software
In addition to the press touch and vibration feedback self-adjustment in the demo, the solution can also achieve press, click, slide and other steering wheel buttons have never been interactive methods, and even the same button can be set to two gears, such as half-press to focus like a digital SLR and full-press to take pictures, so that the user's manipulation of the tactile sense of more three-dimensional fun.
Intelligent expansion, matching multi-terminal control
AUDIOWELL's haptic solid-state button solution for steering wheels supports intelligent expansion, for example, by integrating the solution into the Smart Cockpit domain control, which allows the vibration effect to be adjusted via different smart terminals such as mobile phones and IPADs linked to the Smart Cockpit.
Smooth and fluid lines to beautify the exterior design
The steering wheel with tactile solid-state button solution has no protrusion in the button area, and the overall line is smoother and more fluid than that of the steering wheel with traditional mechanical buttons, which effectively simplifies the industrial design of the whole machine and makes the steering wheel design more concise and beautiful.
