Provided is an internal combustion engine control system capable of simultaneously and suitably carrying out the will of a driver to accelerate and modifications to the throttle opening degree characteristics. An internal combustion engine control system is provided with an accelerator pedal operation amount sensor for detecting the accelerator pedal operation amount, a storage unit for storing multiple different throttle opening degree characteristics of an engine relative to the accelerator pedal operation amount, a switch for selecting the throttle opening degree characteristic pertaining to a plus sports mode in response to an operation, and an engine control unit for controlling the throttle opening degree of the engine on the basis of the selected throttle opening degree characteristic and the detected accelerator pedal operation amount.

Provided is a control device for a hybrid vehicle, which makes it possible to manually select a degree of acceleration in tune with user's preferences and user's intended running quality. Provided is a control device for a hybrid vehicleincluding an engine and a motor for assisting the engine with power, in which an ECUis provided with a first changing unit, which prepares to increase the assist amount of the motorin response to a user depressing a Plus Sport mode switch, and subsequently increases the assist amount of the motorin response to the user pressing an accelerator pedal to cause a variation &#x394;AP in an accelerator position to be at least a predetermined value.

Control device for hybrid vehicle

A through-bore is provided in an outer wall of a passage defining structure defining a liquid passage faced by at least a portion of a vibration generating section, and opens at its inner end into the liquid passage. A vibration absorbing device includes an occluding member mounted to the outer wall to occlude the through-bore, an elastic membrane with its one end facing the liquid passage and other end facing a space defined between the elastic membrane and the occluding member, and a retaining member mounted to the occluding member for retaining the elastic membrane between the retaining member and the occluding member. Thus, a variation in pressure of a liquid in the liquid passage which is induced by the vibration generated in the vibration generating section is absorbed by flexing of the elastic membrane, whereby an exciting force applied from the liquid to the passage defining structure is effectively reduced, and a vibration sound radiated from the passage defining structure is reduced. Moreover, it is possible to suppress the increase in weight of the passage defining structure due to the mounting of the vibration absorbing device to a small level to the utmost. In addition, it is possible to avoid reduction in the sealability due to the liquid pressure in the liquid passage or due to the deterioration of the elastic membrane, and the elastic membrane can be reliably retained between the occluding member and the retaining member to ensure a sufficient sealing.
