An occupant monitoring device for a vehicle includes an image acquisition unit, a memory, a collision detector, and a controller. The image acquisition unit is configured to acquire a captured image of an occupant in the vehicle. The memory is configured to record the captured image acquired by the image acquisition unit. The collision detector is configured to detect collision of the vehicle. The controller is configured to control the image acquisition unit, the memory, and the collision detector. The controller is configured to detect each of consecutive collisions of the vehicle by the collision detector, acquire the captured image after each of the collisions by the image acquisition unit, and record the captured image acquired for each of the collisions on the memory.

An apparatus for operating an airbag of an autonomous vehicle may include: an interior image sensor configured to capture an interior image of a vehicle; an input unit configured to receive collision prediction information from an autonomous driving system and the interior image from the interior image sensor; an airbag module installed at the front and side of the interior of the vehicle, and configured to deploy an airbag; and an airbag control unit configured to estimate the sitting position and dynamic behavior of the passenger from the interior image inputted from the input unit, estimate a collision status from the collision prediction information, determine an airbag to be deployed and a time to deploy the airbag according to the sitting position, and then output a deployment signal to the airbag module.

An occupant protection method and system, and a computer-readable medium, where the method includes: S1: collecting external environment information of a vehicle; S2: determining, based on the environment information, whether there is an obstacle within a monitoring area, and if yes, proceeding to step S3; or if no, returning to step S1; S3: predicting a movement trajectory of the obstacle; S4: calculating a probability of collision between the vehicle and the obstacle based on vehicle body data and motion information of the vehicle, and the movement trajectory of the obstacle; S5: determining whether the probability of collision is greater than a collision threshold, and if yes, proceeding to step S6; or if no, returning to step S1; S6: partially inflating a seat cushion airbag of the vehicle to adjust a sitting posture of an occupant; S7: determining whether a collision is detected, and if yes, proceeding to step S8; or if no, returning to step S1; and S8: fully inflating the seat cushion airbag.

A multiple detection system is applied to a vehicle and includes a contact-type detection module adapted to generate a contact-type detection datum, a contactless-type detection module adapted to generate a contactless-type detection datum, and an operation processor electrically connected with the contact-type detection module and the contactless-type detection module in a wire manner or in a wireless manner. The operation processor sets at least one of the contact-type detection datum and the contactless-type detection datum according to an environmental status of the vehicle to be a main detection result of the multiple detection system, and further sets the other detection datum to be an auxiliary detection result of the multiple detection system, for acquiring a passenger feature inside the vehicle.

A device for protecting a person standing in a motor vehicle comprises numerous airbags installed in a motor vehicle, a scanner for determining where there is empty space adjacent to the person, and a control unit that is configured to only deploy those airbags that inflate into the empty space that has been determined.

Provided is technology that enables preventive processing to be performed at a proper timing as appropriate by detecting early that there is a danger about an occupant. A vehicle occupant protection system 1 includes: an imaging unit 20 configured to take an image of an occupant 90 who is in a vehicle 98, and an inside of a vehicle compartment 99, to acquire image information over time; and a control unit 30 configured to, during operation of the vehicle 98, analyze actions of the occupant 90 in time series on the basis of the image information, and when having determined that, among the actions of the occupant 90, a transfer preliminary action of the occupant 90 leading to place transfer has alone or cumulatively reached a predetermined danger level, perform preventive processing.

The present invention relates to techniques for activating a lock in a vehicle. Said techniques discuss capturing an image of an interior of the vehicle, the image comprising an occupant on a seat of the vehicle, detecting a weight value of the occupant on a respective seat of the vehicle, processing the image for determining whether the occupant is a human or an object or an animal. It further discusses in response to the determination that the occupant is the human processing the image for determining a parameter of the human, and activating a lock based on the parameter, or the weight value and the parameter.

A vehicle occupant protection device includes a seat belt device having a variable force limiter mechanism that can change a force limiter load that an occupant who is sitting on a vehicle seat receives from a seat belt at a time of a frontal collision of a vehicle, an airbag device that deploys an airbag toward the front of the occupant at the time of the frontal collision, a seating position detection unit that detects a seating position at which the occupant is seated, and a control unit that reduces the force limiter load if, compared to a case in which the occupant is positioned within a standard seating region, the seating position of the occupant detected by the seating position detection unit is further toward a vehicle rear than the standard seating region and is within an airbag protection region in which the occupant is protected by the airbag.

Vision-based airbag enablement may include capturing two-dimensional images of a passenger, segmenting the image, classifying the image, and determining seated height of the passenger from the image. Enabling or disabling deployment of the airbag may be controlled based at least in part upon the determined seated height.

Disclosed is a system for controlling a vehicle safety device, the system including: a vehicle safety device configured to protect an occupant; a first occupant detection unit configured to detect a position of the occupant's movable body part; a second occupant detection unit configured to detect a position of the occupant's body part fixed to the safety device; a calculation unit configured to calculate information on the occupant's behavior in the event of a collision accident of a vehicle based on the position of the occupant's movable body part detected by the first occupant detection unit and the position of the occupant's body part fixed to the safety device detected by the second occupant detection unit; and a control unit configured to control an operation of the vehicle safety device for protecting the occupant based on the information on the occupant's behavior calculated by the calculation unit.
