The Diagnostic / The Situation
The touch-capacitive steering wheel controls have become a standard feature in many modern vehicles, including the Ferrari Purosangue and the 12Cilindri. However, these controls can be prone to malfunctions and may not provide the same level of tactile feedback as traditional buttons. This can lead to driver distraction and decreased safety on the road. In this guide, we will explore the process of replacing touch-capacitive steering wheel controls with real buttons, providing a more intuitive and safe driving experience.
Technical Deep Dive
The touch-capacitive steering wheel controls use a capacitive sensing technology to detect the presence of a finger or other conductive object. This technology relies on the principles of capacitance and inductance to detect changes in the electrical field around the control surface. However, this technology can be affected by various factors such as humidity, temperature, and electrical interference, leading to malfunctions and decreased reliability.

In contrast, traditional buttons use a mechanical switch to detect the presence of a finger or other object. This provides a more tactile and reliable feedback, reducing the risk of driver distraction and improving overall safety. The replacement of touch-capacitive steering wheel controls with real buttons involves the installation of new mechanical switches and wiring, which requires careful planning and execution.
