Abstract
A method for controlling/regulating a process in a motor vehicle, in particular a combustion process, gear-shifting process, or braking process, with the help of a characteristics grid map, which is defined by a plurality of performance quantities of the process and represented by data points that have corresponding characteristics-map values. At least one characteristics-map value is determined from the characteristics grid map in a control cycle for an operating point by first determining adjacent data points, which define an interpolation range in which the operating point lies, and by then interpolating between the adjacent data points. To reduce the computational time for interpolation, the at least one characteristics-map value is determined for the operating range within the framework of a linear interpolation based on a minimum number of data points. The minimum number of data points results from a number of the plurality of performance quantities of the process, which define the characteristics map, plus one.
