Method and control tool for operating a valve

摘要

A method for operating a valve actuated by way of an actuator, in particular a fuel injection valve of an internal combustion engine of a motor vehicle, in which a first delay time is identified, which time characterizes a time difference between a point in time of a first change in an energization signal for the actuator and a point in time of a first change in the operating state of the valve corresponding to the first change in the energization signal. According to the present invention, from the first delay time at least one second delay time of the valve is inferred, which latter time characterizes a time difference between a point in time of a second change, different from the first change, in the energization signal and a point in time of a second change in the operating state of the valve corresponding to the second change in the energization signal.

1. A method for operating a fuel injection valve of an internal combustion engine of a motor vehicle actuated by way of an actuator, comprising:
identifying a first delay time which characterizes a time difference between a point in time of a first change in an energization signal for the actuator and a point in time of a first change in an operating state of the valve corresponding to the first change in the energization signal; and inferring from the first delay time at least one second delay time of the valve, the at least one second delay time characterizing a time difference between a point in time of a second change, different from the first change, in the energization signal and a point in time of a second change in the operating state of the valve corresponding to the second change in the energization signal.
