Abstract:
A method for controlling a process in a motor vehicle using a characteristics grid map, comprising:defining the characteristics grid map by a plurality of performance quantities of the process; representing the characteristics grid map by data points having corresponding characteristics-map values; and in a control cycle for an operating point of the process, determining at least one of the characteristics-map values as a function of the characteristics grid map by the steps of: first determining adjacent data points defining an interpolation range in which the operating point lies, and then interpolating between the adjacent data points, the at least one of the characteristics-map values being determined for the operating point as a function of a minimum number of data points using a linear interpolation, the minimum number of data points being calculated from the number of the plurality of performance quantities of the process.
