    Abstract: PROBLEM TO BE SOLVED: To start an internal combustion engine for an automobile possible to control to increase an intake air compression ratio before performing the cranking for facilitating a start of the internal combustion engine in the cold temperature condition as quickly as possible without generating vibration and increasing the intake compression ratio as long as capacity of a capacitor as a cranking power source allows. SOLUTION: An effective output of the capacitor for a cranking motor is the predetermined output threshold value showing the excellent capacity condition or more is judged, and when the effective output is more than the predetermined output threshold value, cranking is performed without increasing the intake air compression ratio independently of the engine temperature.

    Abstract: PROBLEM TO BE SOLVED: To provide a controller for a power train capable of suppressing change of a driving force of a vehicle without depending on other driving force source when a predetermined driving force source causes a failure. SOLUTION: In this controller for the power train constituted such that it has an engine and a motor generator, a fuel injection device, an ignition device, an electronic throttle valve, an actuator, an intake valve, and a valve timing actuator are provided to control an engine output, and the motor generator is driven by electric power generated by power of the engine, an output control means (step S1 or step S3) controlling a normal output controller to suppress the reduction of an engine output accompanied with a failure of an output controller when any of a plurality of output controllers causes the failure is provided.

    Abstract: PROBLEM TO BE SOLVED: To optimumly control closing timing of an intake valve at the stop and start of an internal combustion engine and to attain smooth and quick starting of the internal combustion engine. SOLUTION: In this valve timing control device to be used for a power output device provided with a timing adjusting mechanism capable of adjusting closing timing of an intake valve of an internal combustion engine within a prescribed adjusting angle range, a stopping time control means for setting closing timing of the timing adjusting mechanism to a foremost advancing angle position when a stopping of the internal combustion engine is requested, a stopping history determining means for determining whether a stopping operation (an IG.OFF operation, for instance) based on the will of a driver exists or not between starting of previous time and starting of this time when a starting of the internal combustion engine is requested and a starting time control means for setting closing timing of the timing adjusting mechanism to a foremost lag angle position when the internal combustion engine is started.
