Error correction in a redundant processing system

A method for controlling a processing system, including a plurality of processing devices and a comparison device, the method comprising:

• processing identical information items by the processing devices using associated processing processes;
• furnishing a characteristic value of each of the processing processes, respectively, as a function of the processing that has occurred;
• and
• comparing the characteristic values by the comparison device, and determining a defectively operating processing process based on the comparison;
• wherein defectively operating processing processes are replaced by a processing process restarted on the same processing device.

A non-transitory computer readable medium having a computer program, which is executable by a processor, comprising:

• a program code arrangement having program code for controlling a processing system, including a plurality of processing devices and a comparison device, by performing the following:
• processing identical information items by the processing devices using associated processing processes;
• furnishing a characteristic value of each of the processing processes, respectively, as a function of the processing that has occurred;
• and
• comparing the characteristic values by the comparison device, and determining a defectively operating processing process based on the comparison;
• wherein defectively operating processing processes are replaced by a processing process restarted on the same processing device.

A processing system, comprising:

• a plurality of processing devices, each being configured to process the same input information items respectively using an associated processing process and to furnish a characteristic value as a function of the processing;
• and
• a comparison device to compare the characteristic values and to determine a defectively operating processing process based on the comparison;
• wherein each of the processing devices is configured to replace the processing process executing on it with a restarted processing process if the processing process executing on that processing device has been determined to be operating defectively.
