Servosystem

A servosystem for a motor vehicle comprising:

• a display showing a list of clickable menu items;
• a rotary knob with a rotary element for operating the rotary knob with a list of clickable menu items, with a brake to brake the rotary element and with a rotation sensor to measure the rotation of the rotary element with a resolution of at least 100 per rotation of the rotary element;
• and
• a control for converting the rotation of the rotary element into a scrolling motion through a list and for activating the brake when the last clickable menu item of the list is reached or the first clickable menu items of the list is reached.

• a display showing a list of clickable menu items;
• a rotary knob with a rotary element for operating the rotary knob, with a brake to brake the rotary element and with rotation sensor to measure the rotation of the rotary element with a resolution of at least 450°/α per rotation of the rotary element using the rotary sensor, with α being the smallest angle by which the rotary sensor can be rotated with a momentum exerted on the rotary element of at least 0.15 Nm when the brake is activated;
• and
• a control for converting the rotation of the rotary element into a scrolling motion through the list and for activating the brake when the last clickable menu item of the list is reached or the first clickable menu items of the list is reached.
