SEATBELT DEVICE
First Claim
1. A seatbelt device comprising:
- a webbing that restrains an occupant seated in a seat of a vehicle;
a belt reel that winds the webbing;
a motor that transmits a drive force to the belt reel to wind the webbing;
a current wound position detection unit that detects a current wound position of the belt reel to transmit a current wound position detection signal;
a driving state detection unit that detects a driving state of the vehicle to transmit a driving state detection signal;
a driving state change determination unit that determines a driving state change status based on the driving state detection signal from the driving state detection unit to transmit a driving state change signal;
a target wound position setting unit that sets a target wound position of the belt reel based on the current wound position detection signal and the driving state change signal; and
a motor control unit that controls a current to be supplied to the motor so as to maintain a state in which the current wound position of the belt reel is equal to the target wound position in accordance with the driving state change signal.
