DYNAMIC DAMPING AND SELF-BALANCING AUTOMOTIVE SEAT AND CONTROL METHOD

Disclosed is a dynamic damping and self-balancing automotive seat and a control method, pertaining to the field of intelligent seat system design and control technology. The seat comprises a compliant-control push-rod array with a thin film pressure sensor at the top of the push rods. The control method calculates the difference between individual push rod pressure and the array average pressure, and effects stiffness adjustment via PID combined with feedforward amount, calculation of acceleration through admittance control followed by velocity command generation via integration, and output of differential PWM signals from the PD controller to drive the push rods. The present disclosure employs the aforementioned dynamic damping and self-balancing automotive seat and control method to achieve real-time balancing of occupant pressure distribution and dynamic counteraction of road-induced vibrations. Thereby, it overcomes the limitations inherent in conventional seats with fixed support characteristics, and thus enhances ride comfort and stability.
