## Abstract

A roll stabilization system (1) for a motor vehicle which has a DC voltage converter (6) associated with an electric roll stabilizer (2). By way of the DC voltage converter, a feed voltage can be transformed into a supply voltage for the roll stabilizer (2). To produce as compact a structure as possible, the DC voltage converter (6) is integrated in the electric roll stabilizer (2).

## Claims

### Claim 1

A roll stabilization system for a motor vehicle, the roll stabilization system comprising:
an electric roll stabilizer;
a DC voltage converter being associated with the electric roll stabilizer such that a feed voltage can be transformed by the DC voltage converter into a supply voltage for the roll stabilizer; and
the DC voltage converter being integrated in the electric roll stabilizer.

### Claim 2 (depends on 1)

The roll stabilization system according to claim 1, wherein the DC voltage converter is integrated in a control device of the electric roll stabilizer.

### Claim 3 (depends on 2)

The roll stabilization system according to claim 2, wherein the control device is integrated in a swivel motor of the electric roll stabilizer.

### Claim 4 (depends on 2)

The roll stabilization system according to claim 2, wherein cables leading from the control device to a swivel motor run through a conduit whose outer layer is provided with metal spirals.

### Claim 5 (depends on 1)

The roll stabilization system according to claim 1, wherein the DC voltage converter comprises a control unit by which the feed voltage can be determined and which only initiates a transformation of the feed voltage if the feed voltage differs from the supply voltage.

### Claim 6 (depends on 1)

The roll stabilization system according to claim 1, wherein the DC voltage converter is designed as either a transforming converter or as a converter with a storage throttle.

### Claim 7 (depends on 1)

The roll stabilization system according to claim 1, wherein the supply voltage is between 40 and 48 volts.

### Claim 8

A control device in combination with a motor vehicle roll stabilization system comprising, an electric roll stabilizer having a DC voltage converter associated therewith such that a feed voltage can be transformed by the DC voltage converter into a supply voltage for the roll stabilizer, the DC voltage converter is integrated in the control device which is integrated in the electric roll stabilizer, and the feed voltage on an input side of the DC voltage converter is transformed, by the DC voltage converter, into the supply voltage on an output side.

### Claim 9 (depends on 8)

The control device in combination with the motor vehicle roll stabilization system according to claim 8, wherein the control device is provided with a code.

### Claim 10

A roll stabilization system for a motor vehicle, the roll stabilization system comprising:
an electric roll stabilizer being connected, via a lead, to a vehicle electrical system;
a swivel motor being integrated in the roll stabilizer and comprising electronic components and a control device, and the swivel motor being powered by a supply voltage and the control device regulating the supply voltage transmitted to the swivel motor;
a DC voltage converter having a control unit, the DC voltage converter being connected to the lead for receiving a feed voltage from the vehicle electrical system, and the control unit of the DC voltage converter determining a value of the feed voltage and initiating transformation of the feed voltage, by the DC voltage converter into the supply voltage, only if the value of the feed voltage is different from a value of the supply voltage; and
the DC voltage converter being connected, via cables, to the electronic components of the swivel motor to transmit the supply voltage from the DC voltage converter to the electronic components for powering the swivel motor which produces a restoring torque in the roll stabilization system.
