To provide a sensor unit that can be easily attached to and detached from a seat in which a seated occupant is seated, and a seat equipped with a sensor unit. A sensor unit includes a sensor module including a biological sensor that detects a biological signal of a seated occupant, and a wireless communication unit that is connected to the biological sensor to wirelessly transmit the detected biological signal to an outside; and a sensor holder that holds the sensor module. The sensor holder includes a seat attachment portion detachably attached to an attached portion that is provided in a front surface of a seat cushion at a position at which the seated occupant is abuttable against the attached portion.

A child car set includes an accident-detection system and a child-protection system that is active during a situation detected by the accident-detection system. The child car seat includes a system for triggering the child-protection system based on acceleration measurement.

A process is provided that uses a sensor system incorporated into the passenger cabin of a vehicle to detect children and/or pets left unattended and who are therefore at risk of serious injury or death due to heat stroke. If an unattended child or pet is detected, a variety of alerts are issued over time, the escalating nature of the alerts intended to insure a rapid response. After the system has operated long enough to insure that no child or pet has been left behind, the sensor system is automatically placed into a standby mode. In standby mode the sensor system may either be turned completely off in order to minimize off-line power consumption or it may be incorporated into an on-board security system.

The technology described in this document can be embodied in a system that includes a seat headrest enclosing at least one first acoustic transducer that generates audio output in a first frequency range. The system also includes an adjustable headrest wing disposed in front of the seat headrest, the headrest wing being pivotally coupled to the seat headrest and adjustable to one of multiple positions. The headrest wing includes at least one second acoustic transducer that generates audio output in a second frequency range that includes frequencies higher than the upper end of the first frequency range. The system further includes a controller configured to adjust, for a given position of the headrest wing, one or more parameters of at least one of: (i) the first acoustic transducer and (ii) the second acoustic transducer in accordance with a target acoustic distribution.

A car seat pressure sensor device with wireless communication includes a wireless transmitter and a pressure sensor assembly. The wireless transmitter is configured for wirelessly communicating with a portable electronic device via a wireless signal. The pressure sensor assembly includes at least one pressure sensor and is interconnected with the wireless transmitter. The pressure sensor assembly is operable to turn on or off the wireless signal from the wireless transmitter. The pressure sensor device is configured to turn on the wireless signal from the wireless transmitter for communication with the portable electronic device when the pressure sensor assembly senses a certain weight, and turn off the wireless signal from the wireless transmitter for communication with the portable electronic device when the pressure sensor assembly does not sense the certain weight.

A control system for hybrid vehicles to properly select an operating mode during autonomous operation is provided. An operating mode of the hybrid vehicle is selected from a hybrid mode and an electric vehicle mode. A controller that is configured to: determine an existence of a passenger in a vehicle compartment; select the electric vehicle mode in a case that the hybrid vehicle is operated autonomously while carrying the passenger; and select the hybrid mode in a case that the hybrid vehicle is operated autonomously without carrying the passenger.

A vehicle seating assembly is provided. The seat assembly includes a front seat assembly having a front seat bottom adapted to be mounted to the vehicle body and a front seat back adapted to be mounted to the vehicle body adjacent to the front seat bottom. A sensor cooperates with at least one of the front seat bottom and the front seat back. An actuator is disposed on at least one of the seat bottom and seat back. The seat assembly includes a rear seat assembly behind the front seat assembly. A vehicle seat controller receives an input indicative of a rear occupant seated information and convey a signal to an actuator to move a front seat assembly to an accommodation position in response to the input.

A seating structure includes a base, a seat, a backrest connected to the seat, and an electronic circuit supported by the base. The seat or the backrest includes a carrier and a suspension material secured to the carrier and spanning across an opening formed by the carrier. The suspension material includes a plurality of electrostatic discharge fibers. The electronic circuit is coupled to the electrostatic discharge fibers. The electronic circuit includes an electronic processor and a sensor. The sensor is configured to generate an output signal indicative of an electrical parameter of one of the electrostatic discharge fibers. The electronic processor is configured to apply a drive signal to one of the plurality of electrostatic discharge fibers, receive the output signal from the sensor, and determine a state of the seating structure based on the output signal from the sensor.

The specification and drawings present a new apparatus and method for providing an accurate and convenient weighing of a vehicle occupant using a relocatable/replaceable multi-purpose on-board vehicle occupant weighing (REMBOW) methodology including a REMBOW pad mounted on a REMBOW seat frame in a vehicle to improve safe engagement of an air bag as well as raising and monitoring possible health related issues of the vehicle occupant(s). The occupant weighing can be performed, using, as a non-limiting example, a kemoder elimination of a separate occupant's feet weighing (KEF) technology, where kemoder is a key element for moderating of an accuracy and convenience of an occupant weighing (i.e., a weighing moderator) and for starting a measuring process.

A vehicle seat occupancy detection system includes at least one capacitive sensor member having at least one sensing electrode, an impedance measurement circuit for determining a complex impedance or a complex admittance of the at least one sensing electrode, an evaluation unit for generating an output signal based on a determined complex admittance of the at least one sensing electrode and comparison of the determined complex admittance to at least one predetermined value, and at least one electrically conductive ground connecting member that is intentionally electrically connected to the reference electrode and that is arranged in close proximity to the at least one sensing electrode. The at least one ground connecting member and the at least one sensing electrode are galvanically separated such that, when the seat gets wet, the sensing electrode is directly electrically connected to the reference electrode by the at least one ground connecting member.
