A method for operating a data processing system for processing data, which repeatedly executes a plurality of data processing tasks. The method includes the following steps for the operation of the data processing system: executing a synchronization function in each clock pulse before the start of the relevant data processing task to achieve synchronization of the buffer memories for a plurality of data processing units; executing the individual data processing tasks at their relevant repetition rate in the time grid on one of the data processing units of the data processing system; outputting output data by the individual data processing tasks into respectively provided memory areas of the buffer memory assigned to the clock pulse of the grid; and reading in input data by the individual data processing tasks from respectively provided memory areas of the buffer memory which are assigned to the preceding clock pulses of the grid.

A method for automating a driving function. The method includes an activation of a process controlling the driving function is triggered using an activation condition modelled by a trigger, and the process is temporally controlled by an activation manager during the controlling of the driving function.

A processing system encompasses several processing devices and a comparison device. A method for controlling the processing system encompasses: processing of identical information items by the processing devices using associated processing processes; furnishing a characteristic value of each processing process, respectively as a function of the processing that has occurred; and comparing the characteristic values by way of the comparison device and determining a defectively operating processing process on the basis of the comparison. The defectively operating processing process is replaced by a processing process restarted on the same processing device.

Error correction in a redundant processing system

A method is described for activating tasks in an operating system, characterized by the following features: the tasks are respectively assigned to one of multiple activation schemata; triggering events are assigned to the activation schemata; and if a triggering event occurs, which is assigned to one activation schema among the activation schemata, then the tasks assigned to the activation schema are activated in accordance with the activation schema.

A method for processing data for an automated vehicle, including operating at least two processing units, the at least two processing units being monitored by a monitoring device having at least two self-monitoring monitoring units. Defined monitoring of the processing units is carried out with the aid of the at least two monitoring units. A master functionality of the monitoring units is assumed by a defined monitoring unit.
