A method for determining the lean angle of a two-wheeler in which the axle load on at least one wheel is ascertained and the lean angle is calculated as a function of the axle load.

A controller determines a load weight associated with a plurality of pneumatically independent circuits of a vehicle suspension system. The controller is adapted to receive an electronic pressure signal, at a controller electronic input port, based on a single pneumatic signal representative of respective pneumatic pressures in the plurality of pneumatically independent circuits. The controller is also adapted to determine the load weight based on the electronic pressure signal and control an operation of a function of an associated vehicle based on the load weight.

In a method for warning a vehicle driver of a risk of the vehicle overturning about its longitudinal axis, a control device detects the current transverse acceleration of the vehicle and emits a warning signal based thereon when a risk of overturning is presented. The warning signal is dependent upon at least one transverse acceleration value, which is critical for overturning, detected by the control device while the vehicle is being driven, and a measurement of the transverse acceleration of the vehicle at which the vehicle would actually overturn about its longitudinal axis. The transverse acceleration value that is critical for overturning is determined automatically based on the vehicle behavior exhibited during driving on a curve.

In a method for stabilizing the driving behavior of a tractor-trailer combination, a tilting inclination variable is obtained and a tilting limit is determined on the basis of the tilting inclination variable and is prescribed to a vehicle movement dynamics control system. A vehicle movement dynamics control device carries out the method. In order to improve the stabilization of the driving behavior of tractor-trailer combinations with different loads of the individual vehicles, the respective tilting inclination variable is determined at a plurality of vehicles of the tractor-trailer combination, and the value of the tilting inclination variable for the determination of the tilting limit which is decisive for the determination of the tilting limit is obtained from the tilting inclination variables.

A rollover predictor judgment device for a combination vehicle includes a lateral acceleration sensor, a yaw rate sensor, an articulate angle sensor, and a judgment device in a form of a retarder controller. The judgment device judges that the combination vehicle is in a rollover predictor status when a first lateral acceleration calculated based on a detection value of the lateral acceleration sensor is a first threshold or more or when a second lateral acceleration calculated based on a detection value of the yaw rate sensor and a detection value of the articulate angle sensor is a second threshold or more.

A rollover predictor judgment device (30) for a combination vehicle (1) includes a lateral acceleration sensor (26), a yaw rate sensor (27), an articulate angle sensor (23), and a judgment device in a form of a retarder controller (32). The judgment device judges that the combination vehicle is in a rollover predictor status when a first lateral acceleration calculated based on a detection value of the lateral acceleration sensor (26) is a first threshold or more or when a second lateral acceleration calculated based on a detection value of the yaw rate sensor (27) and a detection value of the articulate angle sensor (23) is a second threshold or more.

An over actuated system capable of controlling wheel parameters, such as speed (e.g., by torque and braking), steering angles, caster angles, camber angles, and toe angles, of wheels in an associated vehicle. The system may determine the associated vehicle is in a rollover state and adjust wheel parameters to prevent vehicle rollover. Additionally, the system may determine a driving state and dynamically adjust wheel parameters to optimize driving, including, for example, cornering and parking. Such a system may also dynamically detect wheel misalignment and provide alignment and/or corrective driving solutions. Further, by utilizing degenerate solutions for driving, the system may also estimate tire-surface parameterization data for various road surfaces and make such estimates available for other vehicles via a network.
