Filed: 1989-11-02
Abstract: PURPOSE:To easily know the reference relation by expressing the reference relation to a parameter of a subprogram of the same compile unit to an argument given to the subprogram by an argument/parameter crossreference list. CONSTITUTION:When an argument is given to a subprogram in a source program, a reference relation linkage information generating means 112 generates an argument/parameter reference relation linkage information file for expressing the information to a parameter of the subprogram of the same compile unit with respect to this argument. A list output means 114 generates a correlation table of the argument and the parameter by using the generated argument/ parameter reference relation linkage information file, and outputs an argument/ parameter crossreference list 105, based thereon. In such a way, the reference relation containing a multistage trace in the subprogram of the argument can be known easily.

Title: Air/fuel ratio control device having learning function
Inventor: ISHIDA KATSUMI
IPC: F02D41/14
Filed: 1989-11-02
Abstract: PURPOSE:To reduce the possibility of occurrence of wrong learning by detecting oxygen partial pressure in an exhaust gas to distinguish the excess and deficiency of fuel, and accumulating deviation quantity from the reference value of the coefficient of control determined by a feedback control means at every reversion of the result of distinction, and comparing the accumulated deviation quantity with the distinction value of the above fuel to increase or decrease a learning value. CONSTITUTION:An excess and deficiency distinguishing means 16 distinguishes the excess and deficiency of fuel, and a means 14 performs the feed back control of fuel supply quantity in a proportional plus integral formula according to the result of distinction. Namely, when the fuel quantity changes from excess quantity to too small one or reversely, the coefficient of control is increased or decreased by P, and the fuel quantity is increased or decreased at the change rate of 1 as long as the too small quantity or the excess quantity continues. An accumulating means 18 accumulates a deviation from the reference value of the coefficient of control at the time when the fuel quantity changes from the excess quantity to the too small one or reversely. In the state where a feedback correction factor has slipped out of the reference value, the absolute value of accumulated value increases and therefore attains a positive criterion value. In this case, since learning value is too small, the learning value is increased to renew it toward a correct value.
