A seatbelt system includes a take-up device configured to take up a seatbelt, and an electronic control unit configured to, when any one of first and second conditions is satisfied, cause a motor to take up the seatbelt. In the first condition, after occurrence of a collision whose physical quantity detected by a detector configured to detect the physical quantity associated with a magnitude of the collision is less than or equal to a first threshold, the physical quantity decreases to less than or equal to a second threshold. In the second condition, after occurrence of a collision whose physical quantity is less than or equal to the first threshold, a first predetermined time elapses, which is estimated to be equivalent to a decrease in the physical quantity to less than or equal to the second threshold.
A seatbelt system for a vehicle, the seatbelt system comprising:
A control method for a seatbelt system, the seatbelt system including a take-up device configured to take up a seatbelt by using driving force of a motor, and an electronic control unit, the control method comprising controlling the motor by the electronic control unit such that the seatbelt is taken up by the motor when any one of a first condition and a second condition is satisfied, the first condition being a condition in which, after occurrence of a collision whose physical quantity detected by a detector configured to detect the physical quantity associated with a magnitude of the collision is less than or equal to a first threshold, the physical quantity decreases to less than or equal to a second threshold less than the first threshold, the second condition being a condition in which, after the occurrence of the collision whose the physical quantity is less than or equal to the first threshold, a first predetermined time elapses, which is estimated to be equivalent to a decrease in the physical quantity to less than or equal to the second threshold.
