Abstract (en)
[origin: DE102006007786B3] The method involves determining an injection control grid with grid points that are specified by a grid parameter and a grid injection quantity, where the grid specifies an operating area of an injection system. Test points are determined based on isolated test injections of the system, where the test points are specified by a test parameter and a test injection quantity. The control parameters of the targeted fuel injection quantity is estimated by using limited linear regression between the grid points and the test points within a partial region of the operating area of the system. An independent claim is also included for a device for estimating the control parameters of an injection system of an internal combustion engine for a targeted injection quantity.
