A position estimation unit (2) comprising a first transceiver device (3) and a processing unit (10) that is arranged to repeatedly calculate time-of-flight (TOF) for radio signals (x.sub.1, x.sub.2, x.sub.3, x.sub.4, x.sub.5, x.sub.6) sent pair-wise between two transceivers among the first transceiver device (3) and at least two other transceiver devices (7, 8, 9); calculate possible positions for the transceiver devices (3, 7, 8, 9), which results in possible positions for each transceiver device (3, 7, 8, 9); and perform Multidimensional scaling (MDS) calculation in order to obtain relative positions of the transceiver devices (3, 7, 8, 9) in a present coordinate system. After two initial MDS calculations, between every two consecutive MDS calculations, the processing unit (10) is arranged to repeatedly perform a processing procedure comprising translation, scaling and rotation of present coordinate system such that a corrected present coordinate system is acquired. The processing procedure is arranged to determine the corrected present coordinate system such that a smallest change for the relative positions of the transceiver devices (3, 7, 8, 9) between the consecutive MDS calculations is obtained.

An occupant protecting device including: a seat provided in a vehicle, the seat including a seat cushion, a seat back, and a headrest, and the seat being provided with an air bag that inflates and deploys at least to a front and both of left and right sides of a head of a seated occupant; and a control device that in the case of having detected or predicted a collision of the vehicle, causes the air bag to inflate and deploy, and in the case that the seat is facing an opposite side to a collision side when the collision has been detected or predicted, delays a timing of causing the air bag to inflate and deploy more compared to in the case that the seat is facing the collision side.

A control device for an object coupling device of a vehicle is configured to actuate a dampening device of the object coupling device such that an object moved by an inertial force from a fixing position along a specified target route to a target impact component of the vehicle can be delayed. The control device is additionally configured to determine a target operating mode of the dampening device from at least two executable operating modes of the dampening device having a different time difference between an exit time of the object from the fixing position and an insert time of a delay of the object to be executed by the dampening device and to control the dampening device into the target operating mode via the at least one control signal.

Airbag systems for use in a vehicle that is operable in a manual-steering mode or an automated-steering mode are provided. In one embodiment, an airbag system includes a primary airbag installed in a dashboard of a vehicle. The primary airbag is configured to be deployed when a collision event is detected, and, when deployed, the primary airbag is configured to protect a person seated in a driver seat of the vehicle. the airbag system also includes an auxiliary airbag configured to be deployed when the collision event is detected. During operation of the vehicle in a manual-steering mode, the deployment of the auxiliary airbag is configured to reduce contact between the primary airbag and a steering wheel of the vehicle when the primary airbag is deployed from the dashboard.

A roof airbag for vehicles and a control method to deploy the roof airbag are proposed. The roof airbag, which protects occupants by minimizing reduction of internal pressure of the airbag in an accident event in which a vehicle rolls over several times in sequence, includes: a main inflator and sub-inflator which generate gas; and a controller configured to ignite the main inflator to deploy an airbag cushion when a rollover accident of a vehicle occurs, and configured to ignite the sub-inflator to increase internal pressure of the airbag cushion when a secondary accident occurs following the primary rollover accident of the vehicle.

A control device of an embodiment includes an airbag inflated at least onto a hood of a vehicle by being filled with gas supplied from a gas supply, a recognizer that recognizes a surroundings situation of the vehicle, an index value deriver that derives an index value indicating a degree of overlap in a vehicle width direction between a traffic participant recognized by the recognizer and the vehicle when the traffic participant comes into contact with the vehicle, and an airbag controller that controls a timing at which the airbag is inflated, on the basis of the index value derived by the index value deriver.

A control system and corresponding control method which is adapted and intended for use in an own vehicle for detecting one or more objects based on environmental data obtained from one or more environmental sensors disposed at the vehicle. The environmental sensors are adapted to provide an electronic control unit of the control system with the environmental data which reflect the areas in front of, laterally next to and/or behind the vehicle. The control system is at least adapted and intended for detecting at least one object by means of the environmental sensors during a predetermined period of time or continuously. A movement of each detected object is determined. The presence of a rotational part in the movement of at least one object is identified, and when a rotational part is present, a probability of an occurrence of a collision between the corresponding object and the own vehicle is calculated.

A pre/post-tensioning controller system for a wheelchair tie-down and occupant restraint system (“WTORS”) will be a comprehensive energy management system for controlling excessive excursions of a wheeled mobility device during various adverse driving scenarios. The system uses multiple pre-tensioning and post-tensioning events during a front, side, or rear impact crash or rollover scenario—and effectively controls excursions by the tensioning of the WTORS equipment at specific and ideal moments. The system also uses tensioning events on the tie-down equipment during a long duration turn or other aggressive maneuvers. The system may also use tensioning events on the occupant restraints. The energy management system can be adapted for use with traditional four-point tie-downs and newer three- and two-point tie-down systems that incorporate fixed or movable bumpers, as well as compressive-type securement systems, and other systems as well, including docking systems.

An airbag device includes a first chamber filled with a gas supplied from a first gas supply part and inflated and deployed in a traveling direction of a vehicle body, a second chamber that is disposed behind the first chamber and able to bring in communication with an inside of the first chamber through a communication section, and a third chamber disposed to cover the communication section and configured to adjust an opening degree of the communication section by being filled with a gas supplied from a second gas supply part and being inflated and deployed.

An airbag system for repositioning a seat occupant in a moving vehicle during a crash event includes: a first inflatable airbag disposed proximate to a front portion of a seat pan; a second inflatable airbag disposed proximate to a rear portion of the seat pan; and inflation control device controlling deployment of the first and second inflatable airbags. The inflation control device includes a programmable controller controlling inflation parameters of the first and second inflatable airbags to achieve a desired lift, subject to monument constraints.
