Abstract
An inertial sensor according to the embodiment includes a first sensor, a first detection circuit, a second sensor, a second detection circuit, and a range setting unit. The first sensor detects a first physical quantity on a first axis. The first detection circuit outputs first detection information based on a first sensor signal from the first sensor. The second sensor detects a second physical quantity on a second axis. The second detection circuit outputs second detection information based on a second sensor signal from the second sensor. The range setting unit performs range setting processing of setting a detection range of the first physical quantity in the first detection circuit based on the first detection information and the second detection information.
Claims15
An inertial sensor comprising:
- a first sensor configured to detect a first physical quantity only on a first axis;
- a first detection circuit configured to perform detection processing of the first physical quantity based on a first sensor signal from the first sensor, and output first detection information;
- a second sensor configured to detect a second physical quantity only on a second axis, the second axis being different than the first axis;
- a second detection circuit configured to perform the detection processing of the second physical quantity based on a second sensor signal from the second sensor including determining whether the second physical quantity exceeds a threshold value, and output second detection information that includes an indication of whether the second physical quantity exceeds the threshold value;
- and
- a range setting unit configured to perform range setting processing,
- wherein the range setting unit is configured to perform the range setting processing of adjusting a detection range of the first physical quantity in the first detection circuit based on both the first detection information and the second detection information including the indication of whether the second physical quantity exceeds the threshold value, such that the detection range of the first physical quantity is adjusted in response to the second physical quantity exceeding the threshold value as detected by the second detection circuit on the second axis that is different from the first axis.
