Abstract
A method for controlling a supercharging device for an internal combustion engine includes controlling a variable (x) using different control characteristics in each of at least four sub-ranges defined by a gradient (dx/dt) of the variable to be controlled (x) and a difference (x) between the variable to be controlled (x) and a control variable (xs). An apparatus for controlling a supercharging device for an internal combustion engine includes a controller having a range of control that includes at least four sub-ranges devided in accordance with a gradient (dx/dt) of the variable to be controlled (x) and a difference (x) between the variable to be controlled (x) and a control variable (xs).
Claims25
A method for controlling a supercharging device for an internal combustion engine, the method comprising the acts of:
- dividing a range of control into at least four sub-ranges in accordance with a gradient (dx/dt) of a variable to be controlled (x) and a difference (Δx) between the variable to be controlled (x) and a control variable (xs);
- and
- controlling a variable (x) using different control characteristics in each of the at least four sub-ranges.
An apparatus for controlling a supercharging device for an internal combustion engine, the apparatus comprising
- a controller having
- a range of control that includes
- at least four sub-ranges devided in accordance with a gradient (dx/dt) of a variable to be controlled (x) and a difference (Δx) between the variable to be controlled (x) and a control variable (xs), wherein the controller controls the variable (x) using different control characteristics in each of the at least four sub-ranges.
