Abstract: A driving force generated by an engine is transmitted to driving wheels (not shown) via an automatic transmission. The engine is provided with an electronically controlled throttle body and the like. An E-ECU performs cooperative control when necessary, so that an output of the engine is obtained in accordance with a load applied thereto. On the other hand, the automatic transmission is provided with a torque converter. Even in the case where the aforementioned predetermined condition has been fulfilled in a T-ECU, if the E-ECU detects a deterioration in performance of the electronically controlled throttle body or the like, the performance of neutral control is prohibited.

Abstract: The engine ECU executes the program including the step of starting a timer that counts the time elapsed from a start request, the step of detecting a temperature of the engine, and the step of calculating a DI ratio r such that the fuel is injected from the in-cylinder injector as well, when the engine is in the very cold or cold state, when there is no abnormality in the fuel system, and when starting of the engine is not yet detected even after a lapse of a predetermined period of time from the start request, only if the fuel pressure in the high-pressure system is not lower than a fuel pressure threshold value.

Abstract: The inventive A/D and D/A conversion device replaces the conventional parameter generators, which are provided in pairs for supplying same filter parameters to the decimation and interpolation digital filters respectively, with a single parameter generator, thereby having the number of parameter generators and reducing the scale of circuit.

Abstract: A semiconductor device is designed and layed out to have a multiple-layer wiring structure and a logic gate cell structure. The multiple-layer wiring structure is constituted by wiring layers each being a vertical wiring layer for producing vertical wirings or a horizontal wiring layer for producing horizontal wirings, and either of the vertical or horizontal wiring layer is provided in plurality. One of the layers of the plurality of wiring layers is that for producing wirings which constitute input terminals of logic gates, and another layer of the plurality of wiring layers is that for producing wirings which constitute output terminals of logic gates. Wiring is carried out along each wiring grid which is provided for each of the plurality of wiring layers so that lines of different grids are alternately arranged.
