Abstract
In a method and a device for predicting a future load signal (tLPr) in connection with the control of an internal-combustion engine, a crank-angle interval (wPr) is determined from the storage of fuel before use (wEE), from the fuel-injection period (wti), and from the calculation time (wB), expressed in units of time or crank-angle units. The future load signal (tLPr) is then determined from a current main-load signal (tL), a current auxiliary-load signal (tL'), which runs ahead of the current main-load signal (tL), and from the crank-angle interval (wPr). The determination is made using a first-order low-pass filter, whose filter constant (wF) is able to be specified in dependence upon load.
