In various examples, systems and methods are disclosed that accurately identify driver and passenger in-cabin activities that may indicate a biomechanical distraction that prevents a driver from being fully engaged in driving a vehicle. In particular, image data representative of an image of an occupant of a vehicle may be applied to one or more deep neural networks (DNNs). Using the DNNs, data indicative of key point locations corresponding to the occupant may be computed, a shape and/or a volume corresponding to the occupant may be reconstructed, a position and size of the occupant may be estimated, hand gesture activities may be classified, and/or body postures or poses may be classified. These determinations may be used to determine operations or settings for the vehicle to increase not only the safety of the occupants, but also of surrounding motorists, bicyclists, and pedestrians.

A remaining lifetime estimating method includes a conversion step of converting a total elapsed time of an airbag into a total elapsed time Tb of the airbag at a predetermined temperature t, according to a formula based on the Arrhenius equation; a remaining use time calculation step of calculating a remaining use time Tx of the airbag by subtracting the total elapsed time Tb from a lifetime Ta of the airbag at the predetermined temperature t; a correction step of performing a correction to increase the remaining use time Tx on the basis of a predetermined value Tc proportional to a power supply time to a vehicle; a determination step of determining whether or not the remaining use time Tx corrected is equal to or less than a predetermined value; and a notification step of issuing a notification regarding the lifetime of the airbag.

An occupant protection system has a component in question reduced in size and cost. The occupant protection system includes: a rollover airbag device provided in a vehicle interior; a battery configured to supply power to the rollover airbag device; a controller configured to determine a rollover of a vehicle and, if a rollover of the vehicle is determined, activate the rollover airbag device using power supplied from the battery; and a backup power source configured to charge power to be used if the battery fails. The controller determines a collision of the vehicle and examines the battery for any failure and, if a collision of the vehicle is determined and the battery is examined to have a failure, activates the rollover airbag device using the power charged in the backup power source.

An emergency escape system and an emergency escape method for a vehicle are provided. The emergency escape system includes a sunroof that is mounted at a headliner of the vehicle and a driving device opening or closing the sunroof by receiving current. A float sensor detects whether the vehicle is filled with water up to a predetermined mounting position. A pressure sensor detects a force applied to the headliner or the sunroof. A controller supplies the current to the driving device in response to receiving from the float sensor a signal indicating that the vehicle is filled with the water up to the predetermined mounting position and determining that the force applied to the headliner or the sunroof, which is detected by the pressure sensor, is greater than a predetermined force.

A side airbag apparatus may include: a seat on which a passenger is seated; an inflator mounted on the seat, and configured to jet gas; a cushion inflated by the gas jetted from the inflator, and deployed toward the passenger so as to move the passenger to an inboard side of the vehicle; and a controller configured to operate the inflator to deploy the cushion before the collision of the vehicle, according to driving information of the vehicle, based on a signal of a sensor mounted on the vehicle.

A method and a control unit for triggering a plurality of actuators of a safety system of a motor vehicle from an energy source are provided. The triggering and a respectively desired trigger time window for the respective actuator are determined based on sensor signals. An on-board electrical system and, in addition, at least one autarky capacitor are provided as the energy source, where the autarky capacitor/s is/are charged from the on-board electrical system. In the event of a destruction of the on-board electrical system, the triggering is adjusted such that at least a part of the actuators provided for triggering are still triggered.
