摘要:
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 quantity describing the wheel rpm is determined for at least one wheel in this method of determining a quantity describing the height of the center of gravity of a vehicle. A quantity describing wheel performance is determined for at least one wheel at least as a function of the quantity describing the wheel rpm of the corresponding wheel. A quantity describing the height of the center of gravity of the vehicle is determined at least as a function of the quantity that is determined for at least one wheel and describes wheel performance of this wheel. This method of determining the quantity describing the height of the center of gravity of a vehicle is used as part of a method of stabilizing the vehicle.

A device for stabilizing a vehicle is described. For this purpose, the device includes first determination device with which at least two vehicle motion quantities describing the vehicle motion, in particular in the direction transverse to the vehicle, are determined. Furthermore, the device includes second determination device with which a characteristic quantity is determined for each of the vehicle motion quantities. The second determination includes an adjustment device with the help of which the variation over time of the characteristic quantities is adjusted to the vehicle's behavior. In addition, the device device includes a control device with which intervention quantities are determined at least as a function of the vehicle motion quantities and the characteristic quantities, which are supplied to an actuator system for performing at least brake interventions and/or engine interventions with which the vehicle is stabilized.
摘要:
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).
摘要:
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.
摘要:
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.
摘要:
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. The method and the device for detecting a tendency of a vehicle to roll over about a vehicle axis oriented in the longitudinal direction of the vehicle are used in the context of stabilizing the vehicle.

The invention relates to a method for operating a closing device (1) in a motor vehicle for detecting a pinching case, wherein an object is pinched between a moving closing element (2) of the closing device and a stop edge (3) of the closing device (1) during a closing operation, having the following steps: determining (S2) an indicator of the instantaneous closing force during a closing operation; determining (S4) an indicator of a force of acceleration indicating a force of acceleration acting on the closing element (2) of the closing device (1) during a closing operation; providing (S5) a closing force threshold value depending on the indicator of the force of acceleration; detecting (S6) a pinch case if the determined indicator of the instantaneous closing force exceeds the closing force threshold value.
