Seat adjustment and sensing system

A seat adjustment system, comprising:

• a seat body;
• a plurality of actuating units, configured to adjust supports of the seat body;
• a sensing unit, including a first sensor configured to obtain physiological information of an occupant and a second sensor configured to obtain seat information of the seat body, wherein the first sensor generates at least one physiological signal according to the physiological information, and the second sensor generates at least one environmental signal according to the seat information, and wherein the physiological information includes at least one parameter of the occupant selected from a group consisting of the occupant's breath, heart rate, body pressure, blood pressure, spine compression, and fatigue degree, and the seat information includes at least one parameter of the seat body selected from a group consisting of seat height, angles of seat back, absence of an object on the seat body, presence of an occupant on the seat body, and sensed pressure on the seat body due to the occupant contact position, a contact range, a contact time, or a dynamic change;
• and
• a control unit, configured to receive the at least one physiological signal and the at least one environmental signal from the sensing unit and control the plurality of actuating units;
• wherein if the at least one environmental signal changes, the control unit transmits a plurality of control signals to the plurality of actuating units, and controls at least one of the plurality of actuating units to adjust the supports of the seat body based on a mapping relationship, and the supports of the seat body are adjusted by the changed actuating unit to make the physiological information of the occupant in a pre-defined range whereby maintaining a relative position between the seat body and the occupant body;
• wherein the mapping relationship is defined as parameters of the plurality of actuating units correlating with the physiological information of the occupant;
• and
• wherein the control unit further controls the plurality of actuating units to periodically change the physiological information of occupant in the pre-defined range.
