A living body detection system includes a transmitting and receiving unit performing transmission and reception of detection waves at an inside of a movable body, the detection waves including directivity in at least one of the transmission and the reception of the detection waves, and a processing unit controlling the transmission of the detection waves and extracting living body information from a receiving signal based on the detection waves received by the transmitting and receiving unit to detect a living body at the inside of the movable body.

A transceiver circuit for a vehicle includes at least one transceiver and a control module for the transceiver. The control module is configured to communicate information relating to a locking/unlocking of the vehicle with a communication device of the user using the transceiver. The control module is further configured to gather information relating to a passenger compartment of the vehicle using the transceiver.

A vehicular cabin monitoring system includes a radar sensor disposed at a vehicle so as to sense interior of the vehicle. The radar sensor includes at least one transmitter that transmits radio signals, and a plurality of receivers that receive radio signals. The vehicular cabin monitoring system, responsive to processing by a processor of radar data captured by the radar sensor and using a neural network, determines occupancy of a seat of the vehicle. The determined occupancy of the seat of the vehicle includes (i) the seat of the vehicle is not occupied, (ii) the seat of the vehicle is occupied by an adult and (iii) the seat of the vehicle is occupied by a child. The vehicular cabin monitoring system generates an alert responsive to determining that the seat of the vehicle is occupied by a child and that no seat of the vehicle is occupied by an adult.

A radar system with frequency scanning beam steering is described for in-vehicle occupant detection and classification for seat-belt reminder functionality (SBR) and airbag suppression. The system includes an antenna system for which the main lobe direction (azimuth angle ?) is changing mostly linearly over frequency, a RF electronic transceiver electronic with at least one transmit channel and one or multiple receive channels with two outputs (I/Q) per channel. The data acquisition and signal processing/interpretation are made by a microcontroller system.

Vehicular control method to avoid collisions in which a smartphone is coupled to the vehicle while in a vehicular compartment. Data is generated from vehicle-resident sensors about operation of the vehicle and transferred from the vehicle to the smartphone while the smartphone is coupled to the vehicle. A communications network with another vehicle is established using the smartphone and the data transferred from the vehicle to the smartphone and data from sensors on the smartphone is transmitted via the smartphone and established communications network to other vehicle, the data including data about location and movement of the vehicle. Then, while the smartphone is coupled to the vehicle, a vehicular operational function is controlled based in part on data transmitted using the smartphone and established communications network to cause movement of the vehicle to change in order to avoid a collision with the other vehicle.

A pair of first airbags and a pair of second airbags are stowed in opposing regions of side wall portions of a vehicle seat. The first airbags are positioned at a seat front side relative to a shoulder area of a seat occupant in a seat side view. The second airbags are positioned at the seat front side relative to a waist area of the seat occupant in the seat side view. The pair of first airbags and the pair of second airbags are supplied with gas, inflate and expand towards the seat width direction inner sides thereof, and are structured such that each pair of airbags, in the inflated and expanded states thereof, push against one another at a seat width direction middle side of the vehicle seat.

A passenger detection device (10) includes a face image obtaining unit (12) obtaining a face image captured in a state in which a passenger in a vehicle irradiated with irradiation light from light sources. The device further includes: a reflected-image position detecting unit (14) detecting, from the face image, positions of respective reflected images of the light sources reflected on eyeglasses worn by the passenger; an eyeglasses feature detecting unit (15) detecting, from the face image, positions of center points of lenses as feature information of the eyeglasses; a head position detecting unit (16) detecting a head position of the passenger on the basis of the positions of respective reflected images; and a face orientation detecting unit (17) detecting face orientation of the passenger on the basis of relation between the head position of the passenger, the positions of respective reflected images, and the positions of center points of lenses.

A computing device in a vehicle can be programmed to receive an occupant position measurement from at least one of an acoustic and a light sensor, determine an estimated occupant size based on occupant weight, estimate a vehicle seat position based on the occupant position measurement, and, control a vehicle occupant safety device based on the estimated occupant size and estimated vehicle seat position.

A method for monitoring a passenger compartment of a vehicle. The passenger compartment has at least one RFID transponder. A readout signal for reading out the RFID transponder is emitted in the method. In response to the emitting, a response signal of the RFID transponder is measured in order to obtain a measured value. Using the measured value, a degree of obscuration that represents an obscuration of the RFID transponder is ascertained in order to monitor the passenger compartment.

System and method for obtaining and recording information about cargo includes a frame defining a cargo-receivable compartment, a position determining system at least partly on the frame and that allows for determination of position of the frame, an identification system on the frame that obtains information about cargo when present in the compartment, a memory component that receives and records information about position and movement of the frame, and the obtained information about cargo when present in the compartment in association with a unique identification of the frame, and a communications system on the frame to enable communication of information to and from the memory component.
