An air-bag apparatus includes: a bag body that is provided on a vehicle seat and that is inflated and expanded at a time of an impact input and prevents at least an upper part of a body of an occupant seated on the vehicle seat from being separated from a seat back of the vehicle seat; an inflator that supplies a gas to the bag body at a time of an impact input; a body size detection part that detects a body size of the occupant seated on the vehicle seat; and an expansion degree adjustment part that adjusts a degree of an inflation expansion of the bag body in accordance with the body size of the occupant detected by the body size detection part.

An airbag controller for a vehicle is proposed. In the airbag controller for a vehicle, an integrated plastic housing without a cover is used to fix a PCB, and a separate grounding device connecting the PCB positioned inside the plastic housing to a vehicle body positioned outside the plastic housing is used in the airbag controller to solve a problem of grounding. Accordingly, it is possible to make the airbag controller be slim and the overall size of the airbag controller be compact.

A steering wheel includes a functional device and a control device, which is electrically connected to the functional device. The functional device includes a functional case, which constitutes a housing of the functional device. The control device includes a control case, which constitutes a housing of the control device. A first connector is partially exposed to an outside of the functional case. A second connector is partially exposed to an outside of the control case. The first connector is coupled to the second connector, so that the functional device is electrically connected to the control device without a harness between the functional case and the control case.

A retainer member is equipped with a microphone facing portion, a drain path, and a stamped wall portion. The microphone facing portion is formed in a cylindrical shape matching an ultrasonic microphone is disposed outside the ultrasonic microphone in a radial direction extending radially from a longitudinal center line. The microphone facing portion extends from a body retaining portion toward a base side in an axial direction. The drain path extends through the microphone facing portion in the radial direction and is capable of discharging water from an inner space in the microphone facing portion. The stamped wall portion is formed in the microphone facing portion and faces the drain path through the longitudinal center line.

An on-vehicle flash flood safety system is disclosed to install a water level sensor between front tires, underneath of vehicle which checks the water level on road. When the water level is found above a predetermined mark, an extendible-retractable shaft is extended which contains a water flow sensor and SONAR device to find the depth and speed of flash flood water. This data is sent to a Control, Display, and Alert Unit which calculates if it is dangerous to enter into such water. If found dangerous, the system gives an audio-visual alarm. System also collects location using GPS and sends location, water, and speed of water data to a computer server to be stored and distributed to other vehicles. By means of the aforesaid performance, on-vehicle flash flood alarm System informs the driver of the motor vehicle to not proceed if there is danger of the vehicle getting swept away.

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 vehicle includes a body of the vehicle and a sensing system coupled to the body. The sensing system includes optical componentry and a glass material, where the glass material at least in part houses the optical componentry and the glass material is at least partially transparent to light at the wavelength of the optical componentry. Further the glass material has mechanical and performance properties that allow the sensing system to be positioned particularly low on the vehicle, at a position that may be of higher risk for damage from debris.

A state detection sensor includes a housing and a position sensing component mounted in the housing. The position sensing component is being configured to provide position data in response to detecting the presence or position of vehicle structure relative to the sensor. The state detection sensor also includes an analog input component mounted in the housing. The analog input component is configured to provide external analog sensor data in response to an analog signal received from an external analog sensor to which the analog input component can be operatively connected. The state detection sensor further includes a component configured to communicate the position data and the external analog sensor data via a serial bus.
