Anti-roll bar for a vehicle

An anti-roll bar for a vehicle, the anti-roll bar comprising:

• a first bar portion for connection to a left-side wheel suspension of the vehicle and a second bar portion for connection to a right-side wheel suspension of the vehicle, and
• an actuator unit connecting the first bar portion and the second bar portion to each other for transferring torque between the first bar portion and the second bar portion,
• wherein the actuator unit has a first selectable mode providing a first predetermined torque ratio between the first bar portion and the second bar portion, and a second selectable mode providing a second predetermined torque ratio between the first bar portion and the second bar portion, the first predetermined torque ratio and the second predetermined torque ratio being different from each other;
• and
• wherein the actuator unit comprises gear wheels for transferring torque between a first shaft of the actuator unit connected to the first bar portion and a second shaft of the actuator unit connected to the second bar portion, the gear ratio between the first shaft and the second shaft being changeable for achieving the first selectable mode and the second selectable mode.

A control unit for controlling an anti-roll bar of a vehicle, the anti-roll bar comprising a first bar portion for connection to a left-side wheel suspension of the vehicle and a second bar portion for connection to a right-side wheel suspension of the vehicle, and an actuator unit connecting the first bar portion and the second bar portion to each other for transferring torque between the first bar portion and the second bar portion, the actuator unit having a first selectable mode providing a first predetermined torque ratio between the first bar portion and the second bar portion, and a second selectable mode providing a second predetermined torque ratio between the first bar portion and the second bar portion, the first predetermined torque ratio and the second predetermined torque ratio being different from each other, and wherein the actuator unit provides a first lever arm for the first bar portion and a second lever arm for the second bar portion, the first lever arm and the second lever arm being connected for transferring torque between the first bar portion and the second bar portion, the ratio between the length of the first lever arm and the length of the second lever arm is adjustable for achieving the first selectable mode and the second selectable mode,

• wherein the control unit is configured to receive input signals representing information about at least one of the vehicle or an occupant of the vehicle and, based on the input signals, control the actuator unit for selectively activating the first selectable mode or the second selectable mode.
