Abstract
An apparatus for estimating a motion of a vehicle occupant, and a method therefor, can store motion estimating models of a vehicle occupant, collect behavior data of a vehicle, determine a traveling mode of the vehicle based on a longitudinal acceleration among the behavior data of the vehicle, and estimate a motion of the vehicle occupant using at least one of the motion estimating models corresponding to the traveling mode of the vehicle. The motion estimating models can include a first model corresponding to a dynamic mode of the vehicle and a second model corresponding to a steady state mode of the vehicle.
Claims20
An apparatus comprising:
- one or more processors;
- and
- a non-transitory storage medium storing a plurality of motion estimating models corresponding to different traveling modes and computer-readable instructions that, when executed by the one or more processors, enable the one or more processors to collect behavior data of a vehicle, determine a traveling mode of the vehicle based on a longitudinal acceleration among the behavior data of the vehicle, select a first motion estimating model corresponding to the traveling mode of the vehicle from among the plurality of motion estimating models, and estimate a motion of a vehicle occupant using the first motion estimating model corresponding to the traveling mode of the vehicle.
A method comprising:
- collecting behavior data of a vehicle;
- determining a traveling mode of the vehicle based on a longitudinal acceleration among the behavior data of the vehicle;
- selecting a first motion estimating model corresponding to the traveling mode of the vehicle from among a plurality of motion estimating models that each correspond to a different traveling mode;
- and
- estimating a motion of a vehicle occupant using the first motion estimating model corresponding to the traveling mode of the vehicle.
A method comprising:
- collecting behavior data of a vehicle, the behavior data including at least a longitudinal acceleration of the vehicle;
- determining a traveling mode of the vehicle based on whether the longitudinal acceleration deviates from a first threshold range, wherein the traveling mode is determined to be a dynamic mode when the longitudinal acceleration deviates from the first threshold range and is determined to be a steady state mode when the longitudinal acceleration is within the first threshold range;
- selecting a first motion estimating model corresponding to the determined traveling mode of the vehicle from among a plurality of motion estimating models, wherein the plurality of motion estimating models includes a first model corresponding to the dynamic mode and a second model corresponding to the steady state mode;
- and
- estimating a motion of a head of a vehicle occupant using the selected first motion estimating model, wherein the estimating includes determining three-axis accelerations of the head of the vehicle occupant based on the behavior data of the vehicle.
