Anti-roll bar for the rolling stabilization of a vehicle and method for operating such an anti-roll bar

A vehicle (100) in combination with at least one stabilizer (105) for anti-roll stabilization of the vehicle (100), the stabilizer (105) comprises:

• a first stabilizer element (110) and a second stabilizer element (115),
• the first stabilizer element (110) is connectable to a first wheel suspension element (120) of the vehicle (100) and the second stabilizer element (115) is connectable to a second wheel suspension element (125) of the vehicle (100);
• a control unit having a read-in unit and a providing unit, the read-in unit reading in a reciprocating movement signal representing reciprocating movement of at least one of the first and the second wheel suspension elements, and the read-in unit transmitting the reciprocating movement signal to the providing unit;
• the providing unit determining a control signal, based on the reciprocating movement signal, using an algorithm of a field-orientated control system;
• and
• at least one electric motor (135), which rotates the first stabilizer element (110) relative to the second stabilizer element (115) in response to the control signal, in order to decouple the first wheel suspension element (120) from the second wheel suspension element (125).

A method (800) for operating a stabilizer (105) for anti-roll stabilization of a vehicle (100), the stabilizer (105) having a first stabilizer element (110) and a second stabilizer element (115), the first stabilizer element (110) being connectable to a first wheel suspension element (120) of the vehicle (100) and the second stabilizer element (115) being connectable to a second wheel suspension element (125) of the vehicle (100), and at least one electric motor (135), which is designed to rotate the first stabilizer element (110) relative to the second stabilizer element (115) in response to a control signal, in order to decouple the first wheel suspension element (120) from the second wheel suspension element (125), the control signal being a signal determined by using an algorithm of a field-orientated control system, the method (800) comprising steps of:

• reading-in (805) of a reciprocating movement signal, and the reciprocating movement signal representing reciprocating movement of at least one of the first wheel suspension element (120) and the second wheel suspension element (125);
• and
• providing (810) the control signal using an algorithm of a field-orientated control system and also using the reciprocating movement signal to produce rotation of the first stabilizer element (110) relative to the second stabilizer element (115) by the at least one electric motor so as to decouple the first wheel suspension element (120) from the second wheel suspension element (125).
