Method and device to prevent a critical operating state of a control device
First Claim
1. A method to prevent or avoid a critical operating state of a control device with a control element and an actuator, as well as a acceleration sensor and an evaluation unit with a storage device, wherein one input of the evaluation unit is coupled to the acceleration sensor and the evaluation unit comprises a further input to receive external desired values for the control device, the method comprising:
- acquiring acceleration measurement values for the control device with the acceleration sensor;
transmitting the acceleration measurement values to the evaluation unit;
processing the acceleration measurement values by the evaluation unit thereby deriving assessment values from the acceleration measurement values;
determining internal desired values with the evaluation unit, and outputting the internal desired values via an output of the evaluation unit for control of the control device; and
if the evaluation unit determines that the derived assessment values reach an assessment threshold that indicates a parameter of a critical operating state of the control device, then varying the internal desired values to control the control device with the evaluation unit until the derived assessment values correspond to a predetermined assessment value which indicates a parameter of a non-critical operating state of the control device.

Abstract
A method and device prevent a critical operating state of a control device with a control element and an actuator, as well as an acceleration sensor and an evaluation unit. An evaluation unit input is coupled to the acceleration sensor and a further input receives external desired values for the control device. The acceleration sensor acquires acceleration measurement values for the control device, these being transmitted to the evaluation unit, with the evaluation unit deriving assessment values from these values. The evaluation unit determines internal desired values and outputs them for control of the control device. If the evaluation unit determines that the derived assessment values reach an assessment threshold indicating a control device critical operating state parameter, the evaluation unit varies the internal desired values to control the control device until the derived assessment values correspond to a predetermined assessment value indicating a control device non-critical operating state parameter.

13. A device to prevent or avoid a critical operating state of a control device comprising a control element and an actuator, the device comprising:
-
an acceleration sensor configured to acquire acceleration measurement values of the control device;
an evaluation unit comprising;
a first input that is coupled to the acceleration sensor to transfer the acceleration measurement values;
a further input to receive external desired values for the control device;
a processor configured to process the acceleration measurement values in order to derive assessment values from the acceleration measurement values, and to generate internal desired values;
an output at which the internal desired values are output to control the control device; and
a comparator configured to compare the derived assessment values with an assessment threshold in order to, in the event that it is established that the derived assessment values reach the assessment threshold which indicates a parameter of a critical operating state of the control device, vary, with the evaluation unit, the internal desired values to control the control device, until the derived assessment value corresponds to a predetermined assessment value which indicates a parameter of a non-critical operating state of the control device;
the device further comprising a storage device coupled to the evaluation unit;
