Abstract
A method for operating a vehicle seat comfort system in which pneumatic components are supplied with fluid by opening and closing at least one solenoid valve. The solenoid valve is opened and closed by applying an electric supply voltage (V). In the opening phase of the solenoid valve, the supply voltage (V) is increased up to a maximum value (V2) in the form of a voltage ramp in a plurality of steps, and in a closing phase of the solenoid valve, the supply voltage (V) is reduced in comparison to the maximum value (v2). In the opening phase of the solenoid valve, the supply voltage (V) is reduced after at least one process of increasing the supply voltage (V) or after each process of increasing the supply voltage.
Claims5
A method for operating a vehicle seat comfort system, in comprising supplying pneumatic components are supplied with fluid by opening and closing at least one solenoid valve, whereby the solenoid valve is opened and closed by applying an electrical supply voltage (V), wherein, in the opening phase of the solenoid valve, the supply voltage (V) is increased in the form of a voltage ramp in a plurality of steps up to a maximum value (V2), and in a closing phase of the solenoid valve, the supply voltage (V) is reduced with respect to the maximum value (V2), wherein, in the opening phase of the solenoid valve, the supply voltage (V) is reduced after at least one instance where the supply voltage (V) is increased, or after each instance where the supply voltage is increased.
