Abstract
An inertial measurement unit (IMU) self-test system includes an IMU and a control circuit. The control circuit is configured to receive IMU data collected by the IMU and inputs from systems external to the IMU indicative of mechanical stimulus, wherein the control circuit utilizes IMU data collected in response to the mechanical stimulus to determine IMU validity.

A method of self-testing an inertial measurement unit (IMU), the method comprising:
- detecting, by a control circuit, a mechanical stimulation event only generated external to the IMU and the control circuit;
- receiving, by the control circuit, IMU data from the IMU that includes IMU data collected with respect to the mechanical stimulation event;
- and
- determining, by the control circuit, IMU validity based on IMU data recorded in response to the mechanical stimulation event.
A method of self-testing an inertial measurement unit (IMU), the method comprising:
- initiating, by a control circuit, a mechanical stimulus originating external to the IMU and the control circuit;
- receiving, by the control circuit, collected IMU data that includes IMU data collected during the mechanical stimulus;
- and
- determining, by the control circuit, IMU validity based on the IMU data collected during the mechanical stimulus.
An inertial measurement unit (IMU) self-test system comprising:
- an IMU;
- and
- a control circuit configured to receive IMU data collected by the IMU and inputs, only from systems external to the IMU and the control circuit, indicative of mechanical stimulus, wherein the control circuit utilizes IMU data collected in response to the mechanical stimulus to determine IMU validity.
