  • Transmission element having a segmented characteristics map
    Patent number: 8385402
    Abstract: A transmission element having at least one input and at least one output is described, the transmission element delivering a functional relationship (t=F(R)) between the input quantity (R) applied to the input and the output quantity (t) that may be picked up at the output and the functional relationship (t=F(R)) being stored in a characteristics map, wherein the characteristics map comprises at least one segment having a lower limit (N(bi)) and an upper limit (N(b(i+1)), a function value (t_(i)=F(N(b_i))) being assigned to the lower limit (N(bi)) and a function value (t(i+1)=F(N(b(i+1))) being assigned to the upper limit (N(bi+1)), and the output quantity (t) being interpolated between the lower limit and the upper limit.
    Type: Grant
    Filed: September 14, 2006
    Date of Patent: February 26, 2013
    Assignee: Robert Bosch GmbH
    Inventors: Michael Eichler, Matthias Beckert

  • Method and apparatus for determining charge quantity during charging and discharging of piezoelectric elements
    Patent number: 6539925
    Abstract: The invention describes a method and apparatus for operating a fuel injection system having a piezoelectric element (10, 20, 30, 40, 50 or 60) for controlling the amount of fuel injected into a combustion engine, characterized in that the piezoelectric element (10, 20, 30, 40, 50 or 60) is controlled based upon the charge it is carrying.
