Definitions
- the invention relates to a method for controlling and regulating a akti ⁇ ven suspension system according to the nä ⁇ in the preamble of claim 1 defined type.
- the driving behavior of a vehicle taking into account a desired driving comfort and a required driving safety, is set by a corresponding configuration of the chassis as well as by a corresponding torsionally rigid body of the vehicle in order to influence the forces acting on the vehicle during operation of the vehicle and be able to counteract the resulting vehicle movements in the desired manner.
- the driving dynamics is considered, which represents a sub-area of technical mechanics or vehicle dynamics and which deals with the forces acting on a vehicle and the resulting vehicle movements.
- the vehicle dynamics itself is basically divided into the longitudinal dynamics, the lateral dynamics and the vertical dynamics of a vehicle.
- the longitudinal dynamics are concerned with the interaction of driving or braking forces on the wheels and with the driving resistances as a function of the route and operating conditions.
- important conclusions for the fuel consumption, the acceleration capability and the design of the drive train and brake system can be achieved from the longitudinal dynamics.
- the lateral dynamics considers the forces, such as crosswinds or centrifugal forces, which distract the vehicle from the direction of travel.
- a balance of these forces can only take place by cornering forces of the tires or wheels, wherein the rubber-tired wheel rolls with respect to its center plane under a entspre ⁇ chenden slip angle.
- Of influence are also the dynamic Rad ⁇ load, the drive and braking forces and the friction properties of Fahr ⁇ track.
- the construction of the suspension and the tire characteristics result driving characteristics, which together with the steering reactions of the driver on the driving behavior, the direction of travel when driving straight ahead and Fahrsta ⁇ bility when cornering close.
- the use of electronic control systems is an attempt to improve Fahr ⁇ dynamics, the longitudinal dynamics, for example, by a Fahrdynamik ⁇ control with targeted influencing the yawing moments by a Bremsein ⁇ grip and the vertical dynamics by reducing the tendency to roll of the vehicle body and influencing the damping properties can be influenced by electronic suspension control.
- active suspension systems are used for the active reduction of vehicle body oscillations resulting from skidding, rolling and pitching movements about the vertical axis, the longitudinal axis and the transverse axis of the vehicle.
- active suspension systems are ange ⁇ controls or the mode of operation of the individual components of Fahrtechniksys ⁇ systems is set such that vehicle body vibrations in a frequency range up to 5 Hz in the desired manner and Be reduced or avoided altogether.
- vibration absorbers with continuously variable damper characteristics are components of active vehicle systems which depend on vehicle acceleration detected via a sensor device and on a control device via appropriate calculation algorithms Actuated control variables are controlled, so that the Anlagen inconvenienceschwin ⁇ ments are reduced taking into account the current operating condition of the vehicle to the desired extent.
- Active suspension systems which are formed with variable-length actuators in the field of structural suspension of a vehicle, spielmik as an active electro-hydraulic suspension system designed to keep the vehicle body in all driving situations at the same level. With such suspension systems, both the suspension and the vibration damping are changed and the level control allows.
- vertically adjustable hydraulic cylinders are arranged in each suspension strut for regulation. The more oil is pumped into the hydraulic cylinder, the stronger the spring is biased and the greater its spring force. The oil flow itself is controlled by regulating and shut-off valves. About the Re ⁇ gelventile the pressure is fed either to the hydraulic cylinder or to the return. The check valves close, for example, when the engine is stopped or in case of malfunction of the suspension system, the flow. All valves will be preferably electromagnetically actuated and sitting as valve units on the axles, each strut being individually controllable.
- the self-checking control and regulating device includes, for example, sensors for speed, lateral acceleration and road conditions, a computer unit with intelligent software and actuators.
- One of the actuators is designed as a proportional damping valve, by means of which the damping forces between a minimum and a maximum value are infinitely adjustable.
- the active suspension systems known from practice and embodied with actively rotatable actuators in the stabilizers include, inter alia, two active stabilizers, a valve block with integrated sensors, a pump, a lateral acceleration sensor, a control device and other supply components. Core elements of such suspension systems are the two active stabilizers, which are integrated instead of conventional mechanical stabilizers in the front and rear axle.
- the actuator is a hydraulically operated swivel motor, in which the swivel motor shaft and the swivel motor housing are each connected to a stabilizer half.
- the active stabilizers convert the hydraulic pressure into a torsional or via the connection in a stabilizing moment.
- the hydraulic pressure is controlled via two electronically controlled pressure regulating valves in such a way that the rolling movement of the vehicle body when cornering is minimized or completely eliminated, high agility and target accuracy are achieved over the entire speed range and an optimum Eigensch- and a good-natured load change behavior is generated.
- the actuators are unpressurized during straight travel or very low transverse accelerations, so that the rotational spring rate of the stabilizer can not harden the basic suspension and the copying movement of the vehicle body is reduced.
- a motor vehicle is known from DE 19820617 A1, which is designed with a vibration damping device or an active vibration reduction system and in which active variable-length control elements are integrated into the power flow of the body torsional vibrations.
- the body torsional vibrations are actively reduced.
- the bodies of cabriolet vehicles are carried out by additional use of material even with a higher torsional rigidity, in order to minimize the occurring during operation Bodors torsionsschwingun ⁇ gene can.
- the present invention is therefore based on the object of providing a method for controlling and regulating an active chassis system for a vehicle, by means of which body torsional vibrations can be reduced in comparison to conventional vehicles without increasing the vehicle weight.
- the total weight of a vehicle is reduced by the activation according to the invention of an active chassis system which is known per se, since additional active or even passive systems for reducing body torsional vibrations can be dispensed with and the body itself becomes cluttered compared to conventional vehicles ⁇ Tors torsional resistance torque is executable.

- the damping forces of the damper 4 are infinitely variable between a minimum and a maximum value, so that the body torsion vibrations determined via the sensor device 2 and the control device 6 are counteracted to a desired extent in a simple manner via a corresponding characteristic of the damper 4 can be.
- the third element of the chassis system 1 is presently designed as an actively rotatable actuator of a stabilizer device 8, which consists inter alia of two active stabilizers 8A and 8B.
