Abstract: The invention relates to a method for preventing tip-over of a motor vehicle in the lateral direction, in which a finite number of predefined driving states is specified; in which a determination is made as to which of the predefined driving states the vehicle is in instantaneously, the predefined driving state thus determined being dependent on sensor signals and on that predefined driving state in which the vehicle was most recently; and as a function of the predefined driving state instantaneously present, at least one braking intervention is carried out in order to prevent the tip-over.

Abstract: A command interpreter for a vehicle stability enhancement system that uses a three degree-of-freedom vehicle model employing non-linear suspension and tire characteristics to calculate stability commands. The command interpreter includes a calculator that calculates a front tire lateral force, a calculator that calculates a rear tire lateral force and a command calculator that calculates a yaw-rate command signal, a lateral velocity command signal and a roll angle command signal. The front tire lateral force calculator and the rear tire lateral force calculator calculate the front and rear side-slip angles. The side-slip angles are then converted to a lateral force, where the conversion is selected based on the tire vertical load. The rear tire lateral force is modified for high side-slip angles so that the rear tire lateral force does not become saturated.

Abstract: A method, and a system using the method, of controlling a towing vehicle that is connected to a vehicle trailer. The method includes sensing a set of vehicle targets and a set of vehicle conditions in response to the set of vehicle targets. The method also includes determining a plurality of differences between the set of vehicle targets and the set of vehicle conditions, determining a trend of the plurality of differences, generating at least one of a symmetric signal and an asymmetric signal based on the trend, and actuating a vehicle system with the at least one of a symmetric signal and an asymmetric signal.

Abstract: A system and method for providing a vehicle roll stability indicator that dynamically estimates the probability for vehicle rollover. The system determines vehicle kinematics from various vehicle sensors. From these kinematic values, the system estimates a roll angle of the vehicle and a bank angle of the vehicle. The estimated bank angle is used to correct the roll angle. The system determines a roll energy of the vehicle and a roll energy rate of the vehicle from the corrected roll angle. The system also calculates a tire lateral load transfer of the relative forces on the vehicle tires, and the duration that any of the tires have been off of the ground. From the roll energy, the roll energy rate, the tire lateral load transfer and the wheel airborne duration, the system calculates the roll stability indicator.

The controller is configured to receive an output of the yaw rate sensor, the lateral acceleration sensor, the steering sensor, and the torque request sensor, generate a torque signal and a braking signal, and transmit the torque signal to a differential in addition to transmitting the braking signal to a braking system.

Abstract: A method for estimating workload placed on the driver of a vehicle. The method comprises receiving workload estimation data. Driving conditions responsive to the workload estimation data are detected. An impact value of at least one of the driving conditions is calibrated. The impact values are combined to determine a current driving workload estimate. The current driving workload estimate is output.

Abstract: In a rollover stability method for a vehicle in a situation which is critical with respect to the driving dynamics, a critical rollover situation is detected by analyzing a control variable and the stabilization intervention is activated or de-activated as a function of the control variable. The regulation intervention is maintained even in driving situations featuring relatively low transverse acceleration if the control variable or a characteristic property of the stability algorithm is calculated as a function of the steering angle and/or the longitudinal vehicle velocity.

Abstract: A method for vehicle information and interaction management. The method comprises receiving vehicle feature data and driver preference data for a vehicle.
