Abstract
A system for roll stabilization of vehicles, in particular motor vehicles, is described, where actuating arrangements are provided. At least one sensor detects a roll parameter, and at least one slewing drive is arranged between halves of the front and/or rear chassis stabilizer, thus creating an initial stress of the stabilizer halves to reduce or suppress the rolling motion and, in the event of roll, applying a counter-torque to the vehicle body as a function of output signals of the sensor. The slewing drive is an electromechanical slewing drive and includes an arrangement for locking the swiveling of the stabilizer halves with respect to one another.
Claims19
A system for providing a roll stabilization of a vehicle that includes an an actuating arrangement, comprising:
- at least one sensor for detecting a roll parameter;
- a front chassis stabilizer;
- a rear chassis stabilizer;
- and
- at least one slewing drive arranged between halves of at least one of the front chassis stabilizer and the rear chassis stabilizer, the at least one slewing drive producing an initial stress of the halves of the at least one of the front chassis stabilizer and the rear chassis stabilizer to achieve one of a reduction and a suppression of a rolling motion, and the at least one slewing drive, in the event of a roll, applying a force to at least one of the halves of the at least one of the front chassis stabilizer and the rear chassis stabilizer as a function of output signals of the at least one sensor, wherein:
- the at least one slewing drive is an electromechanical slewing drive, and
- the at least one slewing drive includes an arrangement for locking a swiveling of the halves of the at least one of the front chassis stabilizer and the rear chassis stabilizer with respect to one another.
A method for providing a roll stabilization of a vehicle, comprising the steps of:
- determining a maximum settable torque from parameters including a maximum motor torque of an electric slewing motor, a gear reduction, an efficiency, and a torque loss;
- determining a required actuating torque;
- releasing a brake and applying a torque force to a low-torque end of the electric slewing motor when the required actuating torque is below a maximum actuating torque;
- applying the brake when the required actuating torque exceeds the maximum actuating torque of an electric slewing drive;
- and
- generating setpoint currents for the electric slewing motor to generate a counter-torque for the roll stabilization.
