A control apparatus is applied to a hybrid vehicle. The hybrid vehicle includes an internal combustion engine and a second MG as driving sources, and a power split mechanism which is capable of changing and transmitting to an output portion transmitting torque to drive wheel, a rotating speed of the internal combustion engine. And, the hybrid vehicle is capable of switching a gear ratio mode of the power split mechanism between a variable gear ratio mode and a fixed gear ratio mode. The control apparatus determines whether or not a switching of the gear ratio modes is prohibited based on a vehicle speed and a gradient of a road. And, when it is determined that the switching is prohibited, the control apparatus maintains the gear ratio mode in the variable gear ratio mode or the fixed gear ratio mode. 1. A control apparatus which is applied to a hybrid vehicle ,the hybrid vehicle including:an internal combustion engine and an electric motor as driving sources;a power transmission mechanism which is capable of changing and transmitting to an output portion transmitting torque to a drive wheel, a rotating speed of the internal combustion engine, the power transmission mechanism being built so as to switch a gear ratio mode of the power transmission mechanism between a variable gear ratio mode and a fixed gear ratio mode; anda computer,the control apparatus comprising a control device that the computer functioning as by implementing a computer program, and the control device being configured to control the power transmission mechanism to switch the gear ratio modes based on a required power to the vehicle and a vehicle speed, whereinthe control apparatus further comprises a control prohibition device that the computer further functions as by implementing the computer program, and the control prohibition device being configured to determine whether or not a switching of the gear ratio modes performed by the control device is prohibited based on a gradient of a road where ...

A driving device includes: a power distribution mechanism configured such that a ring gear is connected to an internal combustion engine, a sun gear is connected to a first MG, and a carrier is connected to a counter shaft in a power transmittable manner; and a clutch mechanism that is able to connect the sun gear to the ring gear. The internal combustion engine, the first MG, the power distribution mechanism, and the clutch mechanism are placed on the same axis. The clutch mechanism is placed on an opposite side to the internal combustion engine across the first MG and the power distribution mechanism. 1. A driving device for a hybrid vehicle , comprising:an internal combustion engine;a first motor generator;an output member connected to a drive wheel in a power transmittable manner;a power distribution mechanism including a first rotating element, a second rotating element, and a third rotating element that are mutually rotatable in a differential manner, the third rotating element being placed between the first rotating element and the second rotating element on a collinear diagram, the first rotating element being connected to the internal combustion engine, the second rotating element being connected to the first motor generator, and the third rotating element being connected to the output member in a power transmittable manner;a second motor generator that is able to output power to the output member; anda clutch mechanism that is able to switch between an engaged state and a disengaged state, the engaged state being a state in which the first rotating element is connected to the second rotating element, and the disengaged state being a state in which the first rotating element is disconnected from the second rotating element, whereinthe internal combustion engine, the first motor generator, the power distribution mechanism, and the clutch mechanism are placed on the same axis, andthe first motor generator and the power distribution mechanism are place between ...

An electronic control unit of a hybrid vehicle is configured to (i) control a rotating electrical machine (MG1) such that when an engagement mechanism (500) is switched from an engagement state to a release state, a counter torque that counteracts a torque of an internal combustion engine (200) applied to the one rotary element is output along with an increase or decrease in the counter torque; (ii) control the rotating electrical machine such that the counter torque is output to be decreased when a rotation speed of the internal combustion engine increases at or after a point of time at which the engagement mechanism is switched to the release state; and (iii) control the rotating electrical machine such that the counter torque is output to be increased when the rotation speed of the internal combustion engine decreases at or after the point of time at which the engagement mechanism is switched to the release state.
