Abstract:
1. An active seat belt apparatus, comprising: a motor which is driven to fasten or unfasten an active seat belt; a motor driving unit which drives the motor; a current measuring unit which measures a value of a current of the motor driving unit in order to determine whether to perform or stop a belt parking function when the active seat belt is unfastened; and a control unit which i) sends a signal for performing the belt parking function to the motor to wind the active seat belt when the active seat belt is unfastened and the value of the current measured by the current measuring unit is smaller than a limit current value, and ii) sends a signal for stopping the belt parking function to the motor to stop winding the active seat belt when the active seat belt is unfastened and the value of the current measured by the current measuring unit while the motor winds the active seat belt is larger than the limit current value.
