A vehicle front passenger seat airbag device includes a plurality of inflators, an airbag, and a controller. The airbag includes a front passenger seat airbag, and a center airbag that includes a vehicle-rear-side end that projects out further toward a vehicle rear side when inflated and deployed than a rear end of the front passenger seat airbag when inflated and deployed. The controller controls timings for igniting each squib included in the plurality of inflators such that a peak internal pressure of the airbag inflated and deployed when an oblique collision or small overlap collision has occurred is delayed, compared to a peak internal pressure of the airbag inflated and deployed when a head-on collision has occurred.

An apparatus including a sensor and a control unit. The sensor may be configured to perform a snapshot configured to detect interior information about a vehicle. The control unit may comprise an interface configured to receive an event warning and the snapshot. The control unit may be configured to determine whether an event is imminent based on the event warning, activate the snapshot when the event is imminent, analyze the interior information based on the snapshot corresponding to the imminent event, determine an arrangement of corrective measures to deploy based on the interior information and the event warning and activate the corrective measures based on the arrangement.

A seatbelt retractor device includes a pre-tensioner section, and a force limiter section that can change a magnitude of a load at which to start reducing tension of the retracted seatbelt. A seatbelt control ECU activates the pre-tensioner section when a deceleration G detected by a floor sensor exceeds a first threshold, and acquires a collision velocity from a radar device and sets a second threshold value to a lower value the greater the collision velocity. The seatbelt control ECU controls the starting load for tension reduction by the force limiter section to be a high load when the deceleration G has exceeded the second threshold within a determination time period after activation of the pre-tensioner section, and controls the starting load for tension reduction to be a low load when which the deceleration G has not exceeded the second threshold within the determination time period.

A vehicle control device has a processor configured to detect collision sound produced by collision between a vehicle and an object based on a sound signal acquired from a sound sensor and calculate reliability of the detected collision sound, determine whether the reliability is at or above a first reference value, determine whether a driving mode of the vehicle is a first driving mode in which a degree to which a driver participates in driving is low, or a second driving mode in which the degree to which the driver participates in driving is higher than the first driving mode, and decide to transfer the driving mode of the vehicle to the second driving mode when it has been determined that the reliability is at or above the first reference value and it has been determined that the driving mode of the vehicle is the first driving mode.

A seat load detection method includes a process in which a control unit records a transition of a load detection signal and a transition of a seat load, a process in which the control unit specifies a timing when a load sensor detects a collision of a vehicle based on a transition record of the load detection signal, and a process in which the control unit calculates a correction value of the seat load based on a difference value between a stable seat load provided after the control unit detects the collision of the vehicle and a stable seat load provided before the load sensor detects the collision of the vehicle.

Method for analyzing a crash event. The method may comprise receiving an acceleration of a vehicle over a predetermined length of time, the vehicle involved in the crash event, determining a change in velocity of the vehicle based on the acceleration, determining vehicle information relating to the vehicle involved in the crash event, and estimating a damage cost for the vehicle involved in the crash event, and/or estimating injuries to occupant(s) of the vehicle involved in the crash event. Estimating damage cost(s) may include determining crash force information for the vehicle, determining physical-damage characteristics of the vehicle subsequent to the crash event, and calculating the estimated damage cost to the vehicle. Estimating injuries to the occupant(s) may include determining occupant information relating to the occupant of the vehicle, calculating estimated forces exerted on the occupant, and calculating an injury probability for various body portions for the occupant.

Present disclosure present a vehicle front passenger seat airbag device, which comprises: a plurality of inflators; an airbag including: a front passenger seat airbag, and a center airbag that includes a vehicle-rear-side end that projects out further toward a vehicle rear side when inflated and deployed than a rear end of the front passenger seat airbag when inflated and deployed; and a controller that controls timings for igniting each squib included in the plurality of inflators such that a peak internal pressure of the airbag inflated and deployed when an oblique collision or small overlap collision has occurred is delayed, compared to a peak internal pressure of the airbag inflated and deployed when a head-on collision has occurred.

A vehicle communication system for a vehicle is described with at least one crash sensor configured to recognize a crash of the vehicle. A passenger recognition system recognizes the number and/or location of passengers in the vehicle. A controller is connected to the at least one crash sensor, the passenger recognition system and a transmitter and configured to generate crash information using crash sensor readout. The controller is further configured to generate a data set including the crash information and number and/or location of passengers in the vehicle from the passenger recognition system. A transmitter is configured to send the data set.
