Method and system for manipulating the movement of a vehicle body of a motor vehicle controllable or adjustable with respect to its movement processes and vehicle
First Claim
1. A method for moderating movement of a vehicle body of a motor vehicle, the method comprising the steps of:
- detecting the movement of the vehicle body by means of sensors,feeding sensor signals corresponding to detected sensor values to a shock absorber control unit,generating a control signal with the shock absorber control unit based at least in part on the detected sensor values; and
controlling actuators with the control signal to moderate the movement of the vehicle body,wherein the control signal further depends on status dependent control algorithms using status dependent filters and status dependent longitudinal and lateral dynamics modules for quasi-stationary and for dynamic processes,the status comprising selectable requirements for the movement of the vehicle body and driving safety requirements including at least a selectable demand for sportiness and a selectable demand for driving safety, andwherein the control signal further depends on at least one of the following;
current and anticipated driving conditions, loading conditions, energy states, and driver activities.

Abstract
A method and a system generates signals for influencing the movement of the body of a vehicle, wherein the chain of movements of which can be controlled or adjusted. The movement of the vehicle body is determined by sensors in relation to at least three wheels of the motor vehicle and the vertical acceleration of the vehicle body, the sensor signals that correspond to the determined sensor values are fed to a shock absorber controller which delivers at least one control signal to control actuators, in particular semi-active or active shock absorbers which are used to influence the movement of the body. The control signal for controlling the actuators is determined by the shock absorber controller from the sensor signals, with the aid of condition-dependent adjustment algorithms, taking into consideration current and/or expected conditions in conjunction with selectable requirements for the movement of the vehicle body and driving safety requirements.
