METHOD AND APPARATUS FOR CONTROLLING A RECIPROCATING-PISTON ENGINE HAVING SEVERAL CYLINDERS |
摘要 |
A method for controlling a reciprocating-piston engine encompassing several cylinders, including generating a discrete-time signal by measuring a state variable of the reciprocating-piston sensor by way of a sensor and an associated evaluation circuit, superimposing onto the signal a summand signal obtained by time differentiation of the signal, or filtering the signal, in such a way that an amplitude of the signal is selectively made larger or smaller at useful frequencies of the signal, and further processing the superimposed signal by way of a user function related to at least one cylinder. A corresponding apparatus, a corresponding computer program, and a corresponding storage medium are also provided. |

1. A method for controlling a reciprocating-piston engine having several cylinders, the method comprising:
generating a discrete-time signal by measuring a state variable of the reciprocating-piston sensor by way of a sensor and an associated evaluation circuit; one of: i) superimposing onto the signal a summand signal obtained by time differentiation of the signal, or ii) filtering the signal, the superimposing or filtering being performed in such a way that an amplitude of the signal is selectively made larger or smaller at useful frequencies of the signal; and after the superimposing or filtering, further processing the signal using a user function related to at least one cylinder. |
