Abstract
In a method for adapting at least one injector of an injection system, in particular of a common-rail injection system of an internal combustion engine of a motor vehicle, where injections take place based on a characteristics map with at least two input variables and at least one output variable, a transition is carried out into a learning mode in which only discrete values are permitted for one of the at least two input variables of the characteristics map.
Claims13
A method for adapting at least one injector of an injection system of a motor vehicle, in which injections are performed based on a characteristics map that provides at least one output variable based on at least two input variables, the method comprising:
- transitioning, by processing circuitry, into a learning mode in which only discrete values are permitted for one of the at least two input variables of the characteristics map;
- and
- updating, by the processing circuitry, the characteristics map during the learning mode;
- and
- adapting an activation period of the at least one injector of the injection system of the motor vehicle, in which injections are performed based on the characteristics map that provides the at least one output variable based on the at least two input variables.
A non-transitory computer-readable medium having a computer program, which is executable by a processor, comprising:
- a program code arrangement having program code for adapting at least one injector of an injection system, in which injections are performed based on a characteristics map that provides at least one output variable based on at least two input variables, by performing the following:
- transitioning into a learning mode in which only discrete values are permitted for one of the at least two input variables of the characteristics map;
- and
- updating the characteristics map during the learning mode;
- and
- adapting an activation period of the at least one injector of the injection system of the motor vehicle, in which injections are performed based on the characteristics map that provides the at least one output variable based on the at least two input variables.
An electronic control device comprising processing circuitry, wherein the processing circuitry is configured to perform a method for adapting at least one injector of an injection system, in which injections are performed based on a characteristics map that provides at least one output variable based on at least two input variables, the method comprising:
- transitioning into a learning mode in which only discrete values are permitted for one of the at least two input variables of the characteristics map;
- and
- updating the characteristics map during the learning mode;
- and
- adapting an activation period of the at least one injector of the injection system of the motor vehicle, in which injections are performed based on the characteristics map that provides the at least one output variable based on the at least two input variables.
