Abstract: In some embodiments, a non-transitory computer-readable storage medium includes instructions to identify, based upon Doppler-speed determination from one or more radars, radar targets within a hitbox for determining a first stationary status of a vehicle based on tracking Doppler-speed radar targets in a hitbox region. The medium also includes instructions to identify, based upon the Doppler speed determination from the one or more radars, field-of-view (FOV) radar targets for determining a second stationary status based on a substantial number and a distribution of Doppler-speed determinations for the FOV radar targets. The medium also includes instructions to confirm, based on detecting a change in either of the first or the second stationary status of the vehicle, an acceleration sensed by an inertial measurement unit onboard the vehicle.
