Abstract
A controller for an injection system having a plurality of fuel injectors includes a map controller. From a desired injection value, the map controller generates a control value for actuating a fuel injector with reference to a specified map. A determination unit determines the actual injection value for at least one injection made, and an adaption unit uses results from the determination unit in order to adapt actuation of the fuel injectors. The adaption unit determines an adaption value for injector actuation from the at least one actual injection value. In engine operation, the adaption unit receives the control values generated by the map controller as input. From this input, the adaption unit generates adapted actuation values as output by applying a mathematical function to the control values generated by the map controller. The at least one adaption value is included in the first mathematical function as parameter.
