A method and a control unit for controlling technical procedures, particularly in a motor vehicle. In the method, a control program of a computing element, particularly a microprocessor, is processed. The control program is subdivided into several tasks and each task is subdivided into several processes. The tasks are processed in a cooperative mode or in a preemptive mode. After the processing of the control program, in order to make possible a simulation as close to reality as possible, particularly an offline open loop simulation, it is proposed that the process sequence be stored during the processing of the control program. Preferably, before the processing of the control program, a unique identifier is assigned to each process, and, during the processing of the control program, only the identifier of the processed process most recently processed before the beginning of a finished task is stored.

A method and a device for reconstructing the sequence of processes of a control program executed by a computing device, in particular a microprocessor, from the contents of a first table and a second table. The control program is subdivided into a plurality of tasks, and each task has at least one process. During execution of the control program, for each completed task, an identifier for a process last executed before the start of the completed task is stored in the first table. The order of the respective completed tasks is stored in the second table. To reliably reconstruct the process sequence, the method and device involve the following. At first, from the contents of the first table and the second table, a third table is generated which contains, for each new task, the identifier for a process last executed before the start of the new task, and the complete process sequence of the control program is then reconstructed from the third table with the knowledge of the process sequence of the individual tasks.

A method and apparatus for stabilizing a vehicle in the presence of a tilt tendency are described. For this purpose, for at least one wheel, a variable quantitatively describing a wheel behavior of at least one wheel is determined. At least as a function of the variable that quantitatively describes the wheel behavior determined for the at least one wheel, a determination is made as to whether a tendency to tilt about a vehicle axis oriented in the longitudinal direction of the vehicle exists.

In a method for determining the lateral acceleration of a motor vehicle, the lateral acceleration is calculated from signals of a wheel sensor and a load sensor. Since in many cases these sensors are already present on the vehicle, e.g., for chassis control, additional sensors are not necessary. The values for the lateral acceleration thus ascertained may then be used in further devices, such as for a vehicle dynamics controller or a device for preventing tipping. For example, usable as a load sensor in the case of a pneumatic suspension is also a pressure sensor which measures the pressure within the pressure bellows of the pneumatic suspension and supplies a signal, corresponding to the mass or the axle load, to the control. The lateral acceleration may be determined with the aid of a steering-angle sensor.

A device and method for stabilizing a combination of a tractor vehicle and least one semitrailer or trailer, the brakes of at least one semitrailer or trailer being set automatically as a function of the yaw rate of the tractor vehicle and the setpoint yaw rate of the tractor vehicle, or as a function of the yaw rate of the tractor vehicle, the speed of the combination and the steering angle.

A device and a method for stabilizing a combination of a tractor vehicle and at least one semitrailer or trailer is described, where the trailer or semitrailer is automatically braked if the semitrailer or trailer buckles with respect to the tractor vehicle at a buckling rate which is greater than a predetermined limit buckling rate.

A method of stabilizing a motor vehicle, preferably to prevent a vehicle from rolling over about a vehicle axis oriented in a longitudinal direction of the vehicle. To do so, a quantity describing the transverse dynamics of the vehicle is determined. This quantity is compared with at least one characteristic value, in particular a threshold value, for this quantity. For the case when the quantity describing the transverse dynamics of the vehicle is greater than or equal to the characteristic value, a speed of the vehicle is reduced to or maintained at a preselectable speed value at least by braking measures on at least one wheel and/or by engine measures and/or by retarder measures (SR).

An apparatus for stabilizing a vehicle combination made up of a tractor vehicle and a trailer or semitrailer. For this purpose, the apparatus contains a first determination arrangement used to determine an inflection angle variable that describes the angle between the longitudinal axis of the tractor vehicle and the longitudinal axis of the trailer or semitrailer. The apparatus also contains a processing arrangement with which a comparison is performed as a function of the inflection angle variable and a comparison variable. The apparatus contains a first actuator arrangement associated with the trailer or semitrailer and with which a brake pressure can be established at at least one wheel of the trailer or semitrailer. The first actuator arrangement is actuated at least as a function of the comparison performed with the processing arrangement. The apparatus furthermore contains a second determination arrangement with which the comparison variable is determined as a function of the velocity of the tractor vehicle and/or as a function of whether stability interventions are being performed for the tractor vehicle.

A method and a device serve to detect a tendency of a vehicle to roll over about a vehicle axis oriented in the longitudinal direction of the vehicle. To do so, a variable describing the wheel rpm is determined for at least one wheel. Furthermore, at least one variable representing the transverse dynamics of the vehicle is determined. For at least one wheel, a variable describing the wheel behavior quantitatively is determined at least as a function of the variable describing the wheel rpm of the corresponding wheel and one of the variables representing the transverse dynamics of the vehicle. Whether the vehicle has a tendency to roll over about a vehicle axis oriented in the longitudinal direction of the vehicle is determined at least as a function of the variable determined for at least one wheel, describing the wheel behavior of this wheel quantitatively.

A method and an apparatus relate to the detection of a tilt tendency of a vehicle about a vehicle axis oriented in the longitudinal direction of the vehicle. For this purpose, for at least one wheel, a variable describing the wheel rotation speed and at least one variable representing the transverse dynamics of the vehicle are ascertained. As a function of one of the variables representing the transverse dynamics of the vehicle, braking torques and/or drive torques are briefly generated and/or modified at at least one wheel. While the braking torques and/or drive torques at the at least one wheel are being briefly generated and/or modified, and/or after they have been briefly generated and/or modified, a variable which quantitatively describes the wheel behavior is determined for that at least one wheel, as a function of the variable describing the wheel rotation speed of that wheel. As a function of that variable quantitatively describing the wheel behavior of that wheel, a determination is made as to whether there is a tilt tendency of the vehicle about a vehicle axis oriented in the longitudinal direction of the vehicle.
