Abstract:
The present invention relates to a method for assisting the driver of a motor vehicle with a fishtailing trailer. A vehicle with a fishtailing trailer can be stabilized in an especially rapid manner in that, in a first state, the fishtailing of the trailer is analyzed by evaluating at least one vehicle state variable, and when critical fishtailing is detected, a warning is output to the driver in a second state so as to induce the driver to brake, and the driver—provided he initiates braking—is assisted in the braking operation by automatic actuation of the vehicle brakes, a brake pressure being set at which the most optimal vehicle deceleration possible is achieved.
Abstract:
A device and the method are for the recognition and rectification of the danger of rollover of a vehicle, outfitted with a regulating system, about a vehicle axis oriented in the longitudinal direction of the vehicle. The regulating system controls actuators using its output signals in accordance with the output signal values. A variable describing the transverse dynamics of the vehicle is determined for the recognition of the danger of a rollover. This variable describing the transverse dynamics of the vehicle is compared to at least one characteristic value, e.g., a threshold value. In the case in which the variable describing the transverse dynamics of the vehicle is greater than, or equal to the characteristic value, the number of all possible combinations of output signal values that may be supplied to the actuators by the regulating system for stability regulation is restricted.
Abstract:
Described is a device for stabilizing a vehicle in critical driving situations, including a vehicle dynamics control system having a control unit, including a vehicle dynamics control algorithm, and at least one actuator and an additional vehicle stability system having an associated actuator. Vehicle dynamics control may be executed in a particularly simple and trouble-free manner when the vehicle dynamics control algorithm is retrofitted with a distribution function which derives an actuating request for an actuator of the vehicle dynamics control system as well as an actuating request for at least one actuator of the vehicle stability system from a controller output variable.
Abstract:
A device is described for stabilizing a vehicle in critical driving situations, including a vehicle dynamics control system having a control unit, in which a vehicle dynamics controller is stored, at least one final control element, and a sensor system for measuring different driving condition variables, and including a rear-wheel steering system having a control unit and a final control element. The electronic stability program may be integrated into a control unit if the electronic stability program algorithm includes a distributor unit which, from a regulator output variable, generates both a setpoint requirement for the final control element of the vehicle dynamics control system and also a setpoint requirement for the final control element of the rear-wheel steering system.
Abstract:
A device for detecting a pendulum motion of a vehicle. The device includes at least one first ascertainment arrangement, with which a lateral-motion-dynamics quantity is ascertained that represents the lateral motion dynamics of the vehicle. In addition, the device includes a second ascertainment arrangement with which a speed quantity is ascertained that describes the vehicular speed. With the aid of a third ascertainment arrangement it is ascertained, as a function of the at least one lateral-motion-dynamics quantity and the speed quantity, whether a pendulum motion of the vehicle exists. For that purpose, it is at least checked whether the at least one lateral-motion-dynamics quantity is greater than an associated threshold value and the speed quantity is greater than an associated threshold value. A pendulum motion of the vehicle exists when the lateral-motion-dynamics quantity is greater than the associated threshold value and when the speed quantity is greater than the associated threshold value.

Abstract:
A method for brake control of a motor vehicle trailer having a brake system that can exert different braking forces on the left and right sides by measuring a lateral force and preferably also a longitudinal and/or vertical force in a trailer coupling, determining an overall braking force for the trailer, and determining a braking difference between the left and right sides of the trailer. The invention makes it possible to stabilize the tractor vehicle with an attached trailer and makes it possible to effectively counteract a weaving or “jack-knifing” of the tractor vehicle during cornering.

Abstract:
A method and a device which, when a pneumatic and/or hydraulic or electromechanical braking system of a vehicle is controlled, make it possible to set a second braking force on at least one wheel brake of one wheel in a defined manner in addition to the defined setting of a first braking force. The first braking force is generated by a first control unit using first hydraulic and/or pneumatic components, whereas the second braking force is generated at predefinable times as a function of the filling of an accumulator with a pressurized medium. The accumulator is a device separated from the first hydraulic and/or pneumatic components which is preferably mounted in the proximity of the wheel brakes and which is filled via a relative movement between at least one wheel and the vehicle body. It is therefore conceivable that, with the aid of a working cylinder attached to a wheel, the accumulator is filled with volume of a medium by utilizing the relative movement between wheel and body.
