The front center airbag device for a vehicle includes a front center airbag mounted on an inner side in a vehicle width direction in a seatback of a vehicle seat serving as a driver's seat and inflated and deployed by supplying gas from the inflator, wherein the front center airbag is configured such that when a side collision of the vehicle is on the driver's seat side, a deployment region in the vehicle front-rear direction is larger and an internal pressure is smaller than when a side collision of the vehicle is on the passenger's seat side.

A control unit performs a lane departure suppression control when a host vehicle is about to depart from a traveling lane. The control unit determines whether a low impact collision has occurred. The control unit performs a secondary collision damage mitigation control when the low impact collision is determined to have occurred while the lane departure suppression control is being performed.

Driving assistance apparatus

A vehicle airbag device comprises an airbag body including a front-rear chamber configured to pass a side of the head of an occupant seated in a vehicle seat and to deploy toward a seat front side as a result of gas being ejected from an inflator actuated, so as to be disposed at the side of the head of the occupant, a leading end chamber is configured to deploy toward a seat width direction inner side from a seat front side end portion of the front-rear chamber so as to be disposed at the seat front side of the head of the occupant, and a shoulder-contact section is configured to contact, from the seat front side, a first shoulder of the occupant so as to restrain the first shoulder, the first shoulder being at an opposite side from a second shoulder of the occupant across which a shoulder belt is worn.

Vehicle airbag device

A seat-mounted airbag device includes a guidance member and an airbag body which includes a front-rear chamber and a distal-end chamber and is accommodated in a side portion of a headrest of a window-side vehicle seat in a state where the airbag body includes an outward winding portion. At the time of a front end collision, the front-rear chamber deploys from the side portion through a gap between the head of an occupant sitting on the window-side vehicle seat and the head of an occupant sitting on a central-side vehicle seat and is disposed in the gap. The distal-end chamber deploys inwardly from a front end part of the front-rear chamber. The guidance member projects from the side portion prior to the deployment of the airbag body so as to be disposed between the airbag body and the head of the occupant sitting on the central-side vehicle seat.

Seat-mounted airbag device

A seat-mounted airbag device includes an inflator that is operated when a vehicle collision is detected or predicted and ejects gas and an airbag body that includes a front-rear chamber and a tip chamber. The front-rear chamber is deployed forward of a seat through a clearance between a window and a head of an occupant from a side portion of a headrest on a window side by the gas ejected from the inflator and disposed between the window and the head of the occupant. The tip chamber is deployed inward in a seat width direction from an end portion of the front-rear chamber on a seat front side and disposed forward of a face of the occupant on the seat front side. The airbag body housed in the side portion includes an outward wound portion wound outward in a roll shape with a seat up-down direction as an axial direction.

A seat-mounted airbag device includes an inflator, an airbag body, and a guide member. The airbag body includes a front-rear chamber and a tip chamber. The front-rear chamber is deployed forward of a seat through a clearance between a window and a head of an occupant from a side portion of a headrest on a window side by gas ejected from the inflator and disposed between the window and the head of the occupant. The tip chamber is deployed inward in a seat width direction from an end portion of the front-rear chamber on a seat front side and disposed forward of a face of the occupant on the seat front side. The guide member protrudes from the side portion prior to deployment of the airbag body and is interposed between the airbag body and the head of the occupant.

A vehicle occupant protection device includes: an airbag main body that includes a front-rear chamber that is deployed to a seat front side along a side of a head of an occupant by a gas ejected from an inflator operated when a collision of a vehicle is detected or predicted, and a tip end chamber that is deployed inward in a seat width direction from an end portion of the front-rear chamber on the seat front side; and a headrest that includes a main body portion that supports the head of the occupant from a seat rear side, and a side portion that is provided on at least a side of the main body portion, that protrudes to the seat front side until a deployment of the front-rear chamber is completed, and that is interposed between the front-rear chamber and the head of the occupant.

A control unit determines whether a rapid acceleration pedal depression operation has been performed. The control unit determines whether a low impact collision has occurred. When it is determined that the rapid acceleration pedal depression operation has been performed and the low impact collision has occurred, the control unit executes a secondary collision damage mitigation control. Consequently, the secondary collision damage mitigation control can be appropriately executed even when a collision that does not cause an air bag to be inflated has occurred.

A driving assist apparatus comprises a driver monitor sensor which detects a state of a driver of an own vehicle installed with the driving assist apparatus. The apparatus determines whether the driver is in a drowsy state, based on the state of the driver detected by the driver monitor sensor. The apparatus determines that a light collision occurs when a light collision determination condition that at least one collision index value representing a level of a collision of the own vehicle is larger than a light collision determination threshold at which an airbag is not developed, is satisfied. The apparatus executes a secondary collision damage mitigation control to apply a braking force to the own vehicle or limit a driving force applied to the own vehicle when determining that the driver is in the drowsy state, and the light collision occurs.

A variable force limiter control system for a vehicle includes a variable force limiter mechanism, a relative speed sensor, an acceleration sensor and an electronic control unit. The variable force limiter mechanism is configured to change a force limiter load. The relative speed sensor is configured to detect a relative speed of the vehicle with respect to a collision object before a collision. The acceleration sensor is configured to detect an acceleration of the vehicle. The electronic control unit is configured to predict a severity of a collision on the basis of at least the relative speed. The electronic control unit is configured to control the force limiter load on the basis of both the predicted severity and the acceleration in an initial stage of the collision of the vehicle.

Variable force limiter control system for vehicle

A vehicle collision detection system that includes: a controller that actuates an occupant restraint device in a case in which a collision between a vehicle and an object has been predicted by a collision prediction section, a collision mode has been determined to be an underride mode by a determination section, the object has been determined to be another vehicle by the determination section, and an acceleration detected by a first acceleration sensor is at or above an underride-mode-actuation determination threshold that is lower than a normal-actuation determination threshold for the occupant restraint device.

Vehicle collision detection system

A vehicle airbag device comprises an airbag that receives gas supplied from an inflator and that is adapted to be inflated and deployed in front of an upper body and above thighs of an occupant seated in a vehicle seat. The airbag includes, in the event that the gas has been supplied inside the airbag and the airbag inflates and deploys, an inflation section having an endless annular shape as viewed along a vehicle width direction, and a hollow section formed in a central portion of the inflation section. The hollow section is in communication with an exterior of the airbag, and air at the exterior flows into the hollow section during inflation and deployment.
