Left and right stabilizer bars are provided between left and right wheels of a vehicle. A control unit controls an actuator to control a rotation angle of the right stabilizer bar with respect to the left stabilizer bar. The control unit determines whether the vehicle is moving, whether a vehicle speed is less than a first threshold value, and whether a vehicle state is in transition from a moving state to a stopped state. A detection unit detects a control amount of the actuator. When the vehicle is moving, the vehicle speed is less than the first threshold value, the vehicle state is in transition from the moving state to the stopped state, and the control amount of the actuator is greater than zero, the control unit decreases the control amount of the actuator such that the control amount of the actuator becomes zero before the vehicle speed becomes zero.

An active roll control apparatus is provided. To adjust a stiffness value of the stabilizer bar by moving a stabilizer bar installed between left and right wheels of a vehicle and extending in a first direction and a stabilizer link connected to the stabilizer bar, the active roll control apparatus includes a sliding part having one side connected to the stabilizer bar and the other side connected to the stabilizer link to slide the stabilizer link in a second direction perpendicular to the first direction, and a movement restricting part installed at the sliding part to restrict movement when the sliding part slides.

The present invention relates to a stabilizer for a vehicle which is installed between a pair of wheels of the vehicle and includes a first bar disposed to extend in a width direction of the vehicle; an actuator supported by a vehicle body of the vehicle and coupled to the first bar and a first connecting member to move the first bar in the width direction of the vehicle; and a second bar having one side connected to the first bar and the other side connected to one side of a wheel supporter which supports one wheel of the pair of wheels of the vehicle, wherein, when the first bar is moved in the width direction of the vehicle, the other side of the second bar is moved so that the one side of the wheel supporter is moved in an upper direction or a lower direction of the vehicle.

An active roll stabilizer includes a divided torsion bar (1) having torsion bar parts (2, 3) which are arranged one behind the other along a torsion bar axis. An actuator (4) for transmitting torsional torques to the torsion bar (1) is provided.

A motor housing (11) of the electric motor (7) is connected, by means of only one of the two axial ends of said motor housing, to the actuator housing (5) for conjoint rotation.

A roll stabilizer for a motor vehicle includes a torsion bar and a vibration damper located on the torsion bar. The vibration damper is configured to vibrate relative to the torsion bar. The vibration damper includes two half-shells formed together about the torsion bar. Damper elements are disposed between the half-shells. The damper elements can be adjusted via an adjustment component to alter the rigidity of the damper elements.

A method for actuating an actuator device of a roll stabilizer for a vehicle. The actuator device has a supply line connection for supplying a supply voltage, a converter for supplying an alternating voltage using the supply voltage, and at least two phase lines for supplying the alternating voltage to actuator connections of an actuator which can be operated using the alternating voltage. The method has a step of reading an interruption signal, which indicates an interruption in the supply of the supply voltage or a deviation from the supply voltage at the supply line connection and a step of providing a protection signal at an interface with a protection device using the interruption signal in order to at least partly prevent a generator voltage which is or can be fed into the phase lines via the actuator connections from being forwarded in response to the protection signal.

A vehicle includes wheels, suspension links, a torsion bar, and electronically controlled dampers. The suspension links support the wheels. The torsion bar generates a force to resist a tilting of the vehicle in the body roll direction. The electronic control dampers connect the torsion bar to the suspension links. At least a portion of each suspension links is located in front of the corresponding electronically controlled damper.
