Abstract
A method for predefining a current through a solenoid coil of a solenoid valve, a closing point in time of the solenoid valve being detected with the aid of a sensor, a sensor value being monitored, and, when a premature closing of the solenoid valve is identified based on the monitored sensor value, the current through the solenoid coil of the solenoid valve is increased.
Claims13
A method for predefining a current through a solenoid coil of a solenoid valve, comprising:
- detecting a closing point in time of the solenoid valve via a sensor;
- monitoring a sensor value;
- and
- when a premature closing of the solenoid valve is identified based on the monitored sensor value, increasing the current through the solenoid coil of the solenoid valve.
The method as recited in one of the preceding claims, wherein the current (I) through the solenoid coil (17) of the solenoid valve (10) is increased in an activation process following an activation process in which the premature closing of the solenoid valve (10) has been identified.
The method as recited in claim 1, wherein the solenoid valve is used for a solenoid valve injector for injecting fuel into a combustion chamber of an internal combustion engine. The method as recited in claim 10, wherein the fuel is injected from a high-pressure accumulator.
An arithmetic unit for predefining a current through a solenoid coil of a solenoid valve, comprising:
- an arrangement for detecting a closing point in time of the solenoid valve via a sensor;
- an arrangement for monitoring a sensor value;
- and
- an arrangement for, when a premature closing of the solenoid valve is identified based on the monitored sensor value, increasing the current through the solenoid coil of the solenoid valve.
A computer program, which prompts an arithmetic unit to carry out a method for predefining a current through a solenoid coil of a solenoid valve, the method comprising:
- detecting a closing point in time of the solenoid valve via a sensor;
- monitoring a sensor value;
- and
- when a premature closing of the solenoid valve is identified based on the monitored sensor value, increasing the current through the solenoid coil of the solenoid valve.
A machine-readable storage medium having a computer program stored thereon, which prompts an arithmetic unit to carry out a method for predefining a current through a solenoid coil of a solenoid valve, the method comprising:
- detecting a closing point in time of the solenoid valve via a sensor;
- monitoring a sensor value;
- and
- when a premature closing of the solenoid valve is identified based on the monitored sensor value, increasing the current through the solenoid coil of the solenoid valve.
