Abstract:
A device for stabilizing a vehicle after a collision, including a control device having a regulation algorithm, a sensor system for recording various quantities that describe the vehicle state, and an actuator for carrying out a stabilization intervention. The driving state of the vehicle is monitored for the occurrence of a collision, a setpoint value is calculated for a vehicle movement quantity, the setpoint value being at least partly independent of the steering instruction of the driver, and the vehicle movement quantity of the vehicle is regulated to this setpoint value in the case of a collision.

Abstract:
A method for stabilizing a vehicle in a transverse direction, in which: for a first braking force distribution in which each vehicle wheel is braked using the maximum braking force transmittable to the road surface in the current driving situation, the yawing moment acting on the vehicle is ascertained; for at least a second braking force distribution that differs from the first braking force distribution in that at least one wheel is not braked using the maximum braking force, the yawing moment acting on the vehicle is ascertained; a setpoint yawing moment is ascertained; and from at least the first and second braking force distributions, the braking force distribution whose associated yawing moment comes closest to the setpoint yawing moment is set at the vehicle.
Abstract:
In a method for setting a limiting value of a vehicle state variable in a driver assistance system, in particular in an electronic stability program ESP, accelerations are measured by the airbag sensor system, and are used in the event of an accident of low to medium severity to determine limiting values of the yaw acceleration and the yaw rate. These limiting values are used for monitoring the functionality of the yaw rate sensor.
Abstract:
In a method for automatically correcting a state variable of a vehicle, in the event of the vehicle having departed from the predefined lane a vehicle control system is re-parameterized in such a way that an intervention predefined by the driver is converted in a reduced manner into a change in a vehicle state variable.
Abstract:
A device and method for preventing a motor vehicle engine from stopping are described, which includes a device for preventing a motor vehicle engine from stopping in an automatic brake operation, the device including the following features of a unit for providing an engine speed signal that corresponds to the speed of the motor vehicle engine, and a brake interruption unit, which is developed to interrupt the brake operation if the engine speed signal assumes a value that lies below a predetermined threshold value, the threshold value being greater than an engine stop threshold value that indicates a minimum speed of the motor vehicle engine.
Abstract:
A method and device for actuating an active and/or passive motor vehicle safety system in a driving situation in which the vehicle executes a rotary movement about the vertical axis of the vehicle. A variable describing the rotary motion is measured, and this variable is processed by a mathematical model, which determines information therefrom about the future rotary motion of the vehicle. This information in turn may be used to control the vehicle safety systems as a function of the situation and prepare them for a possibly imminent collision.

Abstract:
A method for operating a hydraulically working brake system of a vehicle, in particular a motor vehicle, having at least one brake line assigned to at least one wheel brake, the brake line being connected or connectable via a switchable valve to the high pressure side of a pump unit for brake fluid. It is provided that the valve is closed when an unexpected pressure drop is detected in the brake line. Also described is a brake system for a vehicle, in particular a motor vehicle.
Abstract:
In a method for deactivating a safety function in a motor vehicle after being activated, the safety function may be deactivated by the driver only after a dead time has elapsed.
