METHOD AND DEVICE FOR FILLING AND EMPTYING A SEAT CUSHION

摘要

The invention relates to a method and to a corresponding device for filling at least one seat cushion of a seat with, and emptying same of, a fluid, in which, during a filling or emptying operation, depending on a switching state of an actuating member designed for filling or emptying the at least one seat cushion, a first pressure value determined upstream of a throttle point through which the fluid flows, and a second pressure value determined downstream of the throttle point, are detected, and, depending on the first pressure value and the second pressure value, an estimated value of a mass of fluid supplied to or removed from the at least one seat cushion is determined.

主权项

1. A method for filling at least one seat cushion of a seat with a fluid, and emptying same of a fluid, comprising:
during a filling or emptying operation, a first pressure value (pin) which is determined upstream of a throttle point through which the fluid flows and a second pressure value (pout) which is determined downstream of the throttle point are detected as a function of a switched state of an actuating element which is designed for filling or emptying the at least one seat cushion , and determining an estimated value (m_EST) of a mass of the fluid which is fed to or removed from the at least one seat cushion is determined as a function of the first pressure value (pin) and the second pressure value (pout).
