Abstract
A control system for supercharging an internal combustion engine equipped with an automatic transmission includes superchargers which provide a variable capacity controlled by a supercharging capacity controller according to a supercharging capacity control pattern. The supercharging capacity is controlled so as increase at engine speeds higher when a demand to shift the automatic transmission to a lower speed gear is present than when a demand to shift the automatic transmission to a higher speed gear is present. Change of supercharging capacity is suspended for a predetermined period of time when a demand to shift the automatic transmission is present.
Claims8
A control system for supercharged internal combustion engine equipped with an automatic transmission, comprising:
- transmission shift control means for causing the automatic transmission to be shifted to a desired speed gear according to a gear shift control pattern;
- supercharging means, capable of changing its supercharging capacity, for supercharging the internal combustion engine;
- and
- supercharging control means for changing said supercharging capacity of said supercharging means according to a supercharging capacity control pattern;
- said transmission shift control means switching the supercharging capacity control pattern according to said desired speed gear and causing a delay of any change in said supercharging capacity, according to said supercharging capacity control pattern, by said supercharging control means when said transmission shift control means demands a shift of the automatic transmission to a desired speed gear.
