摘要： A detecting unit outputs an object signal corresponding to an inertial force. A corrected signal is generated by correcting the object signal. A first environment value is obtained at a first time point. A second environment value is obtained at a second time point after the first time point. An environment difference value which is a difference between the first and second environment values is calculated. An environment change detection signal is output when an absolute value of the environment difference value is larger than a predetermined determination threshold. A first averaged signal is output by averaging a corrected signal in a predetermined period continuing to the first time point. A second averaging signal is output by averaging the corrected signal in a predetermined period continuing to the second time point. An offset difference value which is a difference between the first and second averaged signals is calculated. The offset difference value is stored when the environment change detection signal is output. The corrected signal is generated by adding the stored offset difference value to the object signal. This method can easily reduce the output offset even if an environment, such as an ambient temperature, abruptly changes.

摘要： A sensor apparatus of the present invention includes a first output terminal for outputting a sense signal, and a failure diagnosis circuit for determining whether a failure diagnosis object section is normal or abnormal, to output a failure detection signal from a second output terminal in the case of determining abnormality. The time required for an output concerning the failure detection signal from the failure diagnosis object section to reach the second output terminal is shorter than the time required for an output concerning the sense signal from the failure diagnosis object section to reach the first output terminal, thus leading to improvement in reliability under abnormal condition.

摘要： The invention provides an angular velocity sensor which is provided with a smoothing circuit having a large smoothing time constant so that it can be reduced in size and integrated into an IC. Smoothing circuit (9) is provided with first switch (11), first capacitor (12), second switch (13), second capacitor (17) and control signal feeding module (15). Control signal feeding module (15) feeds first switch (11) and second switch (13) with a signal for controlling ON/OFF. According to this configuration, an equivalently large smoothing time constant can be set by reducing the frequency of the switching control signal of control signal feeding module (15), even if the capacities of first capacitor (12) and second capacitor (17) are small. Especially in case the capacitors are integrated into an IC, their area of occupation can be reduced to reduce the size of the angular velocity sensor and integrate the same into the IC.
