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 airbag apparatus includes an airbag and an airbag controller. The airbag is disposed in a movable member and configured to be able to deploy in different sizes in a front-to-back direction of an automobile. The movable member can move in the front-to-back direction in front of a passenger in the automobile. The airbag controller is configured to control a size of the airbag to be deployed, according to a position to which the movable member is moved.

A vehicle and a method of controlling an airbag of a vehicle enhances the efficiency in airbag deployment by predicting the possibility of collision of the vehicle in advance from a driving manipulation pattern of a driver and actively and variably adjusts a threshold value for deploying an airbag on the basis of a result of the prediction of the possibility of collision. The method of controlling an airbag of a vehicle includes determining a possibility of collision of the vehicle from a driving manipulation pattern of the vehicle, and variably adjusting a threshold value for deployment of the airbag on the basis of a result of the determination of the possibility of collision.

A vehicle and a method of controlling the vehicle may include a seat belt apparatus to reduce the tension of the seat belt in the normal situation in which the collision does not occur by appropriately adjusting the tension of the seat belt based on the driving state of the vehicle, providing convenience to a passenger. In the collision situation, the safety of the passenger may be ensured by sufficiently increasing the tension of the seat belt. The vehicle according to an exemplary embodiment of the present invention includes: a seat belt provided to adjust a tension; a driving assistance device configured to obtain vehicle driving information for assisting a driving of the vehicle; and a controller coupled to the driving assistance and configured to adjust the tension of the seat belt to correspond to a driving state of the vehicle based on the vehicle driving information obtained through the driving assistance device.

A control device for a vehicle seat belt, includes: a retraction unit that is configured to retract a seat belt through use of a driving force of a motor and to stop retracting the seat belt when the motor is stopped from being driven; an acceleration measurement unit that is configured to measure an acceleration of a vehicle; a state detection unit that is configured to detect whether or not the vehicle is in a stable state while running; and a control unit that is configured to stop driving the motor when the acceleration measured by the acceleration measurement unit during driving of the motor has remained lower than a first set acceleration for at least a first set time and the vehicle has remained in the stable state detected by the state detection unit for at least a second set time.

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.

A method for activating a passenger protection device of a vehicle. A relative velocity value, which represents a relative velocity between the vehicle and an object, and at least one correction value are read in. In a further step, a velocity reduction value, which represents a decrease of a velocity of the vehicle when the vehicle collides with the object, is ascertained using the relative velocity value and the correction value. Finally, an activation signal for activating the passenger protection device is generated using the velocity reduction value.

A vehicle rollover sensing system using driving information for optimization includes a longitudinal-velocity estimator determining a longitudinal velocity of a vehicle using a wheel speed, a steering angle, and GPS vehicle velocity information; a lateral-velocity estimator determining a lateral velocity of the vehicle using the longitudinal velocity, a yaw rate, a steering angle, a lateral acceleration, and GPS vehicle heading direction information; a rollover type determinater deciding a rollover type of the vehicle using the longitudinal velocity and the lateral velocity of the vehicle; and a restraint device deployment determinater determining whether or not to deploy a vehicle restraint device according to the decision by the rollover type determinater.

An active seat belt control apparatus is controlled according to a state of a vehicle. A control method for the active seat belt control apparatus includes: collecting, by a communication unit, state information about the vehicle; determining, by a controller, whether to activate a pulling operation of a seat belt using the collected state information; and activating the pulling operation of the seat belt using a motor.
