A vehicle seat control device includes a collision prediction part that predicts a collision direction of a collision occurring in a vehicle, a first driving part that rotates a vehicle seat around an axis of the vehicle in a substantially upward/downward direction, and a controller that controls the first driving part such that a direction of the vehicle seat is changed to an opposite direction with respect to the collision direction on the basis of the predicted collision direction.

Vehicle seat control device, vehicle seat control method and vehicle seat control program

An occupant protection device includes a drive unit which adjusts a degree of tension of a seat belt and a control unit which controls the drive unit to tension the seat belt to remove looseness of the seat belt when a vehicle has been switched from an automated driving to a manual driving.

Occupant protection device, method for controlling occupant protection device, and program

A vehicle control system includes: an automated driving control part that performs automated driving in which at least one of acceleration/deceleration and steering of a vehicle is automatically controlled; a driving operation element that receives an operation of an occupant with respect to acceleration/deceleration and steering of the vehicle; an operation element state change part that makes the driving operation element disabled when the automated driving by the automated driving control part is performed; and an alternative operation reception part that receives an operation which is different from the operation with respect to the driving operation element by the occupant when the driving operation element is disabled by the operation element state change part, wherein the automated driving control part controls at least one of acceleration/deceleration and steering of the vehicle based on the operation by the alternative operation reception part.

Vehicle control system, vehicle control method, and vehicle control program

A travel safety device for a vehicle comprises: an object detecting unit () for detecting an object existing in the traveling direction of the vehicle (); a correlation calculating unit () for calculating a correlation involving the distance between the vehicle () and the object on the basis of a detection result of the corresponding object detecting unit (); an automatic brake unit () for automatically decelerating the vehicle (); a safety device () including a seatbelt device () for automatically tightening the seatbelt () and releasing the tightening thereof; and safety device operation control units () for determining a possibility of a contact between the vehicle () and the object on the basis of the correlation calculated by the correlation calculating unit () and for controlling the operation of the safety device () where it is predicted that there is a possibility of a contact; wherein the safety device operation control units () simultaneously actuate the automatic brake unit () and seatbelt device () where it is predicted that there is a possibility of a contact.

Travel safety device for motor vehicle

A seatbelt apparatus () includes a seatbelt () for restraining an occupant () in a seat () of a vehicle, an actuator () for tightening the seatbelt () at various levels of tension and for loosening the seatbelt (), plural collision prediction devices () for predicting occurrence of a collision, and a control device () for controlling the actuator () so as to exert one of the various levels of tension on the seatbelt () depending on the prediction results by the collision prediction devices ().

Seatbelt apparatus

The seat belt device includes a first unit, a second unit, seat belt webbing, a spindle, a first pretensioner, a second pretensioner, and a controller. The first unit determines a possible collision of an automobile in response to a manipulation of the automobile by a driver. The second unit detects the collision of the automobile. The first pretensioner has a motor to rotate in response to a signal indicative of the possible collision determined by the first unit. The second pretensioner is pyrotechnically driven to rotate in response to a signal indicative of the collision detected by the second unit. The controller is configured to cancel an operation of the first pretensioner after an activation of the second pretensioner. The first pretensioner includes a limiter for restricting the motor from transmitting a driving force to the spindle exceeding a predetermined threshold.

Seat belt device

A seat-occupant restraining apparatus is provided which includes a bag, accommodated in a shoulder belt, for restraining a seat occupant in a seat, and when a vehicle collides, expands the bag with a high-pressure gas produced by an inflator. A relief valve, which opens according to an increase in the internal pressure of the bag, is provided in a gas passage for supplying the high-pressure gas from the inflator to the bag. If the bag is completely expanded by the high-pressure gas from the inflator and the internal pressure of the bag reaches an appropriate value, the relief valve opens and discharges an extra high-pressure gas from the bag, whereby the internal pressure of the bag can be controlled to the appropriate value without causing variations. According to the above-described constriction, it is possible to realize a stable air vent function superior to that of a vent hole, without providing a vent hole in the bag of an air belt assembly.

Seat-occupant restraining apparatus

A portion of a shoulder belt,of an air belt apparatus touching the breast portion of an occupant is composed of an inflatable rubber bag,shaped like a tube, a webbing,for covering the outside of the bag,so that tension is produced in case of a car collision, and a pad,for further covering the outside of the webbing,The pad,has a three-layer structure: the outermost layer is made from raised cloth,such as moquette, or the like, which feels pleasant to the touch; the intermediate layer is made from an urethane sheet,having elasticity; and the innermost layer is made from base cloth,for protecting the urethane sheet,The pad,has rifts,extending longitudinally. The pad,and an elastic element,made of a belt-like rubber sheet are sewed together with stitches,so that the rifts,and,are connected to each other. When the bag,is inflated in case of a car collision, the webbing,is inflated by the pressure of the bag,Further, the elastic element,is stretched and the pad,is inflated. As a result, the shoulder belt,is inflated as a whole. Accordingly, it is possible to improve the feeling given by a belt of an air belt apparatus.

Air belt apparatus

A seat-occupant restraining apparatus for a vehicle is provided that includes both an air bag and air bag inflator and an air belt and air belt inflator. An ignition controller controls the ignition of both the air bag and air belt inflators. An acceleration sensor is included. The ignition controller calculates the magnitude of the shock of collision, based on input from the acceleration sensor at the time of a collision of the vehicle by integrating the acceleration over a preset time, and the magnitude of the shock is compared with a first and second threshold, both of which are stored in advance. If the calculated shock is less than the first threshold, the ignition controller does not output an ignition signal to either the air bag or the air belt. For shocks between the two threshold values, the air belt assembly is operated. For shocks greater than the second threshold, both the air belt and the air bag are activated.
