    • The present invention aims at preventing such a situation that anyone of the divided injection amounts becomes less than a minimum compensation amount for a fuel injection valve, in case of conducting a two-step injection (weakly stratified combustion) in which a part of fuel is injected during intake stroke and the remaining fuel is injected during compression stroke. To this end, at the time of instructing to conduct the two-step injection, a whole injection amount TI is divided into: an injection amount TIH for homogeneous combustion to be injected during intake stroke, and an injection amount TIS for stratified combustion to be injected during compression stroke, based on a division ratio corresponding to a target air-fuel ratio. Further, each of the injection amounts TIH and TIS after division is compared with a minimum compensation amount MIN for the fuel injection valve. Based on the result of the comparison, the injection amount, which has a smaller division ratio, is set to be zero, and the injection amount, which has a larger division ratio, is set to be the whole injection amount TI, when either one of the injection amounts TIH and TIS is judged to be less than the minimum compensation amount MIN. Alternatively, the injection amount, which has the smaller division ratio, is set to be the minimum compensation amount MIN, and the injection amount, which has the larger division ratio, is set to be the remainder obtained by subtracting the minimum compensation amount MIN from the whole injection amount TI.

    • An automobile control device includes a function that can control drive torque of a starting device to an arbitrary value, and a positive rotation detecting unit having at least one of a function to detect whether an engine rotates positively and a function to detect whether the engine does not rotate reversely. The control device also has an idle stop function to increase the drive torque of the starting device when the positive rotation detecting unit detects that the engine rotates positively or does not rotate reversely. Accordingly, problems of malfunctions such as a reduction in a system voltage, abnormal wear of a brush in a starter motor, and breakage of a semiconductor switch are solved that are found in a conventional automobile control device having the idle stop function and that are caused by flowing of overcurrent when a starter is driven during swing-over that occurs immediately before engine stop.

    • To detect opening/closing of a neutral detection hydraulic switch by a detection apparatus and detect breakage of a wiring line connected between the detection apparatus and the switch. Since a second contact and an ECU are connected to each other by two wiring lines, even if one of the wiring lines is broken, opening/closing of the neutral detection hydraulic switch can be detected through the remaining one of the wiring lines. Since different voltages are applied to the wiring lines through resistance type voltage dividing circuits, the occurrence of the wire breakage can be detected making use of the fact that the voltage detected by the ECU upon opening of the neutral detection hydraulic switch when one of the wiring lines is broken is different from the voltage when none of the wiring lines is broken.
