An occupant restraint system for a vehicle includes: a seat belt device configured w restrain an occupant seated on a vehicular seat with a webbing, in which one end of the webbing is wound around a winding device and the other end is fixed to one of the vehicular seat and a vehicle body, and the seat belt device is configured so that a motor provided in the winding device is driven to wind the webbing; and an electronic control unit configured to drive the motor so that a prescribed amount of the webbing is wound, when a first condition is satisfied.

An information processing apparatus mountable on a first moving body obtains second movement information including the position and velocity of a second moving body and first movement information including the position and velocity of the first moving body. A second predicted path is determined from the second movement information, and a first predicted path is determined from the first movement information. Then, the information processing apparatus generates travel assistance information including information for directing the first moving body to take a detour from the first predicted path in a direction corresponding to a difference between arrival time periods taken for the second moving body and the first moving body to reach an intersection point of the second predicted path and the first predicted path. Finally, the generated travel assistance information is output.

A method and computer program are provided for operating a motorized two-wheeled vehicle, in particular a motorcycle that includes a sensor system for accident recognition that generates measuring signals. The sensor system is used for recognizing a rotation of a front wheel of the two-wheeled vehicle that deviates from a normal steering movement and allows an inference concerning a collision of the two-wheeled vehicle with another object. Moreover, the invention relates to a computer program for carrying out the method.

An occupant protection device for a vehicle includes a seat, a three-point seatbelt device, and a belt airbag device. An occupant to board the vehicle is to sit on the seat. The three-point seatbelt device includes a seatbelt extendable across a front of an upper body of the occupant sitting on the seat. The belt airbag device includes a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt, and that is configured to be deployed when a collision occurs. The belt airbag includes a belt-direction deployment section extendable and deployable along the shoulder belt section, and an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section. The sections are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat.

An occupant protection device includes: a collision prediction unit configured to predict a collision state including a collision direction in a vehicle; a seat direction detection unit configured to detect a direction of a seat that is rotatable around a vertical axis of the vehicle with respect to the vehicle; a driving unit configured to adjust a degree of tension of a seatbelt; and a control unit configured to control the driving unit in accordance with the collision direction with respect to the vehicle predicted by the collision prediction unit and the direction of the seat with respect to the vehicle detected by the seat direction detection unit to change the degree of tension of the seatbelt.

According to one aspect, a vehicle safety system includes an actuatable controlled restraint (ACR) comprising a seatbelt for restraining a vehicle occupant. The ACR is actuatable to control payout and retraction of the seatbelt. The system also includes a controller configured to determine operating conditions of the vehicle and to control the actuation of the ACR in response to the determined operating conditions of the vehicle. The ACR has a normal restraint condition and an enhanced restraint condition, the controller being configured to actuate the ACR from the normal restraint condition to the enhanced restraint condition in response to determining abnormal driving conditions of the vehicle.
