Patent ID: 8090505

Claim:
A vehicle seat belt apparatus, comprising: a motor for driving a belt reel having a belt wound thereon; a trigger configured to detect a change in a traveling state of a vehicle to output an activation signal that instructs activation of said motor; a lateral acceleration detector configured to detect lateral acceleration acting on the vehicle; a slip state detector configured to detect a slip state quantity of the vehicle; and a control configured to, when the activation signal output by said trigger has been received, control an amount of current supply for activating said motor on the basis of at least one of a signal of the lateral acceleration output by said lateral acceleration detector and a signal of the slip state quantity output by said slip state detector, wherein said control increases the amount of current supply to said motor as at least one of the lateral acceleration and the slip state quantity increases, wherein said control obtains a first current amount determined on the basis of the lateral acceleration detected via said lateral acceleration detector and a second current amount determined on the basis of the slip state quantity detected via said slip state detector, and said control determines the amount of current supply to said motor by comparing the first and second current amounts and selecting a smaller of the first and second current amounts.
