Abstract: A method for determining the probability a handling truck tipping over includes determining a respective normal force acting in the z direction for at least two of at least three wheels of the handling truck. At least two normal forces are compared and the probability of the tipping of the handling truck is determined on the basis of the comparison.

Abstract: A device for monitoring a pressure sensor, which is positioned in a braking system of a vehicle. For this purpose, the device contains arrangement with which, during a braking action, a first vehicle motion variable is ascertained, which characterizes a vehicle motion in the longitudinal direction. The device further includes arrangement with which a mass variable is ascertained, which characterizes the mass of the vehicle. Using further arrangement, it is ascertained, for the monitoring of the pressure sensor, whether the first vehicle motion variable lies within a value range for the first vehicle motion variable, whose limits are ascertained as a function of the mass variable.

Abstract: An electronic brake system for a vehicle which has control modules for adjusting the braking force at the wheels of the vehicle, a control module which determines at least the driver's braking command, and at least one communications system which connects the modules to each other, where, to supply the elements with energy, at least two independent vehicle electrical systems (E.sub.1, E.sub.2) are provided, at least one of the elements being connected to an electrical system different from that to which the other elements are connected.

Abstract: A system for the generation of signals for control or regulation of a passenger car and/or truck undercarriage controllable or regulable in its sequences of movement, where a three-step operation is provided. In a safety mode, particular allowance is made for road safety, and in a comfort mode for travel comfort. Moreover, a predetermined undercarriage setting is selected in a standard mode. These selections are based on the movements determined between the wheels and the vehicle superstructure, such as spring deflection movements. Furthermore, based on the determined spring deflection movements, the actual value P of the wheel load fluctuations and the movements of the vehicle superstructure are inventionally determined.

Abstract: Basing on signals (Vi) representing the vertical movements of the vehicle body at selected points (Pi) of the body, and basing on second signals (Xarvl', Xarvr', Xarhl', Xarhr') representing the relative movements between the wheel units and the body of the vehicle, the inventional system infers selected components of movement of the vehicle body, such as heave, roll and pitch movements or the vertical movement of the body at the front and rear axles as well as the roll movement. These components of movement are weighted differently. Basing on these differently weighted components of movement, second body movements are inferred at the points where the wheel suspension systems attach to the body.

Abstract: The object of the inventional system is the so-called "modal" variant of the skyhook damping. The advantage of this variant over the local version is essentially constituted by enabling an individual damping of the eigenoscillation forms. Moreover, a definitive roll or sway moment distribution can be adjusted. For that purpose there are signals determined which represent the local vehicle body movements at selected points of the vehicle body. Basing on these signals, the heave, roll and pitch movements are inferred. These movements are differently weighted depending on travel maneuvers. By actuation of the damper systems dependent on the weighted heave, roll and pitch movements a specific influencing of certain components of the body movement is possible.

Abstract: A system for chassis control, specifically of passenger cars and trucks, where the control parameters of the controlled loop are varied for control of the chassis properties in contingence on the state of travel of the vehicle as determined by sensors. Specifically determined for recognition of the state of travel are parameters representing the vertical-dynamic state of movement of the vehicle and/or the individual driving style of the operator. This procedure is based upon the relative movements between the vehicle body and at least one wheel, captured by sensors.

Abstract: A system for changing the damping characteristics of shock absorbers, based on the signals (Xar'(t)) of the relative movements such as the spring deflection velocity, between the vehicle superstructure and wheels, additional signals (Xar"(t)), such as the spring deflection acceleration, are determined. The two signals are logical linked so that the control of a vehicle variable, such as the activation of adjustably designed shock absorbers, is carried out. This makes it possible to change the characteristic of the shock absorber in operating phases of low damping forces of the shock absorber. This feature optionally reduces noise at damping characteristic changes.

Abstract: A system for inferring actual wheel load fluctuation based on signals representing the relative movements between the wheel units and the vehicle body. Possible changes of the actual wheel load fluctuation are precalculated as a function of a possible change of the undercarriage characteristic, whereupon by scanning of certain criteria a determination is made as to whether a situation critical to road safety is given and whether in the case of a situation critical to the road safety the undercarriage characteristic is to be adjusted for minimization of the wheel load fluctuations.
