Abstract
A control device for controlling a passenger protection device for a vehicle includes an input unit configured to receive a first acceleration signal in a first axial direction and a second acceleration signal in a second axial direction which are generated by an acceleration sensor disposed in a side door of a vehicle, a determination unit configured to determine whether a collision has occurred in the side door of the vehicle using at least one of the first acceleration signal and the second acceleration signal, and a control unit configured to control a passenger protection device disposed adjacent to the side door of the vehicle based on a result of determining whether the collision has occurred.
Claims18
A control device for controlling a passenger protection device for a vehicle, the control device comprising:
- an input unit configured to receive a first acceleration signal for a first axial direction and a second acceleration signal for a second axial direction generated by an acceleration sensor disposed in a side door of the vehicle;
- a determination unit configured to determine whether a collision has occurred at the side door of the vehicle using at least one of the first acceleration signal and the second acceleration signal, wherein the determination unit is configured to generate a metric using one or more deformation information calculated from the first acceleration signal and the second acceleration signal and to compare the metric with a threshold set in response to the metric to determine whether the collision has occurred at the side door,
- wherein the one or more deformation information comprises displacement information, velocity information, and velocity moving sum information;
- and
- a control unit configured to control the passenger protection device, which is disposed adjacent the side door of the vehicle, based on a result of determining whether the collision has occurred.
A method of controlling a passenger protection device for a vehicle, the method comprising:
- receiving a first acceleration signal for a first axial direction and a second acceleration signal for a second axial direction generated by an acceleration sensor disposed in a side door of the vehicle;
- determining whether a collision has occurred at the side door of the vehicle using at least one of the first acceleration signal and the second acceleration signal wherein the determining comprises:
- generating a metric using one or more deformation information calculated from the first acceleration signal and the second acceleration signal, wherein the one or more deformation information comprises displacement information, velocity information, and velocity moving sum information;
- and
- comparing the metric with a threshold set in response to the metric to determine whether the collision has occurred at the side door;
- and
- controlling the passenger protection device, which is disposed adjacent the side door of the vehicle, based on a result of determining whether the collision has occurred.
