The disclosure is generally directed to providing a relaxation regimen to an occupant of a vehicle. In one example method, a processor evaluates a physiological condition of the occupant. The physiological condition can be a heart rate, hear-rate variability, a breathing rate, and/or a blood oxygen level. The processor also identifies an opportune time to offer the relaxation regimen. The relaxation regimen may be offered based on evaluating the physiological condition of the occupant and on identifying the opportune time. Furthermore, the relaxation regimen may be recommended based on the customer preference or usage patterns and the opportune time. The opportune time can be when the vehicle is moving in a cruising mode of operation, is in a stopped or parked state, or is moving in stop-and-go traffic, or location. In another example method, a processor may offer the relaxation regime based on a movement status of the vehicle.

A vehicle seat in accordance with the present disclosure includes a seat bottom and a seat back. The seat back is coupled to the seat bottom and arranged to extend in an upward direction away from the seat bottom. The vehicle seat further includes an electronics system.

A method for forming polyurethane foams for vehicle seat components in a molding apparatus is provided. The method includes a step of directing one or more polyol compositions into a mold. Each of the one or more polyol compositions includes a polyol, water, and a catalyst. The method also includes a step of directing an isocyanate composition into the mold, the isocyanate composition including one or more isocyanates. The one or more polyol compositions and the one or more isocyanates are combined into a reaction composition that forms a foamed vehicle seat component. Characteristically, the mold has a shape that defines a foamed vehicle seat component. Characteristically, either the one or more polyol compositions and/or the isocyanate composition includes a liquid antimicrobial agent that is a liquid at temperatures above 10° C.

A plurality of pressure-sensitive switches of a sitting sensor (1) has a first pressure-sensitive switch group including a first pressure-sensitive switch (SW11) including a first specific pressure-sensitive switch and a second pressure-sensitive switch (SW21), and a second pressure-sensitive switch group including first pressure-sensitive switches (SW11, SW12) including the first specific pressure-sensitive switch, and a second pressure-sensitive switch (SW22), in which in the first pressure-sensitive switch group, the first pressure-sensitive switch (SW11) and the second pressure-sensitive switch (SW21) are disposed adjacent to each other along a left-right direction of a seat (SE), in the second pressure-sensitive switch group, the first pressure-sensitive switches (SW11, SW12) and the second pressure-sensitive switch (SW22) are disposed adjacent to each other along a front-rear direction of the seat (SE), and turning on the first pressure-sensitive switch and the second pressure-sensitive switch causes a current to flow between a pair of terminals (T1, T2).

A first pressure-sensitive switch group of a seating sensor includes first pressure-sensitive switches (SW11 to SW13) and second pressure-sensitive switches (SW21 to SW23) located on one side of a seat in a left-right direction from the first pressure-sensitive switches, and includes a first pressure-sensitive switch pair including the first pressure-sensitive switch (SW11) and the second pressure-sensitive switch (SW21), and the first pressure-sensitive switch (SW13) and the second pressure-sensitive switch (SW22) located between the first pressure-sensitive switch (SW11) and the second pressure-sensitive switch (SW21), a second pressure-sensitive switch pair including the first pressure-sensitive switch (SW12) and the second pressure-sensitive switch (SW22), and a third pressure-sensitive switch pair including the first pressure-sensitive switch (SW13) and the second pressure-sensitive switch (SW23), in which seating is detected when both the first pressure-sensitive switch and the second pressure-sensitive switch in at least one of the first to third pressure-sensitive switch pairs are turned on.

A passenger identification apparatus for vehicles is provided to identify a passenger through integration of a sensor that senses change in permittivity and a sensor that senses change in pressure. The apparatus includes a permittivity change sensing unit that is installed in the seat and senses change in capacitance generated by permittivity of the passenger seated on the seat and a pressure change sensing unit that is installed in the seat and senses change in pressure generated by a load of the passenger seated on the seat. A controller adjusts power supplied to the permittivity change sensing unit and the pressure change sensing unit and determines whether the passenger is seated on the seat and the type of passenger using permittivity and pressure change values sensed by the permittivity change sensing unit and the pressure change sensing unit.

A disembarkation action determination device includes: an upper body movement detection section configured to detect for a first state in which an upper body of an occupant sitting on a vehicle seat has been lifted upright, based on a signal from a first sensor provided inside a vehicle cabin; a hand position detection section configured to detect for a second state in which a hand of the occupant sitting on the vehicle seat is in proximity to or contacting a door inside handle, based on a signal either from the first sensor or from a second sensor separate from the first sensor; and a disembarkation action determination section configured to determine that the occupant has initiated a disembarkation action in cases in which the first state has been detected by the upper body movement detection section and the second state has been detected by the hand position detection section.

A system for detecting an occupant in a vehicle includes a proximity sensor installed at a back of a seat and detecting an object. An automotive key locks and unlocks a door. A starter starts and stops an engine of the vehicle. A controller is configured to determine whether the occupant is in the seat based sensor values of the proximity sensor, a door unlock signal from the automotive key, and a starting signal from the starter.

A vehicle includes an internal camera configured to obtain first image data; an external camera configured to obtain second image data; an impact detecting sensor configured to detect an external impact and generate an impact detection signal; a memory configured to store the first image data and the second image data; and a processor electrically connected to the impact detecting sensor and configured to generate an impact event when a strength of the impact detection signal exceeds a threshold, and in response to the impact event being generated, control the memory to store the first image data and the second image data in the memory.
