A shifting device for an electric vehicle having a virtual manual transmission system, that is configured to realize a variety of shift patterns and torque characteristics. The shifting device comprises: an indicator that indicates a shift pattern; and an indication switcher that switches the shift pattern indicated in the indicator to another pattern. At least any one of the number of the shift positions and a virtual gear stage assigned to the shift position in the shift pattern switched by the indication switcher is different from that in the previous shift pattern indicated in the indicator before switched by the indication switcher.

Shifting device for electric vehicle having virtual manual transmission system

A shifting device in which a selected shift position can be confirmed easily, and which can be fitted easily in vehicles. The shifting device comprises: a restriction member that restricts a movement of a shift lever into a predetermined shift slot in a first shifting mode, and that cancels the restriction of the movement of the shift lever in a second shifting mode; and an indicator that indicates a first pattern when the first shifting mode is selected, and that indicates a second pattern when the second shifting mode is selected.

Shifting device for vehicle

A sound production device includes memories, processors, a rotation speed correlation value acquisition device configured to acquire a rotation speed correlation value of a rotating body, and a speaker. A noise order sound has a characteristic in which a sound pressure of the noise order sound reaches a maximum sound pressure in a first range of the rotation speed correlation value, and the sound pressure becomes smaller than the maximum sound pressure in second ranges adjacent to both sides the first range. When the rotation speed correlation value falls within the first range, the processors do not output a dummy noise. When the rotation speed correlation value falls within either of the second ranges, the processors output the dummy noise.

A virtual manual transmission system for an electric vehicle for simulating the behavior of a vehicle having a manual transmission by controlling a motor while protecting an electric storage device. A controller is configured to: change torque of the motor when a virtual manual shifting is executed by operating a clutch device, an accelerator device, and a shifting device; and reduce a regulation on a change rate of the torque of the motor or an input/output power to/from the electric storage device.

A control apparatus for a hybrid vehicle is configured to control the hybrid vehicle. The control apparatus is provided with: an arithmetic operator configured to arithmetically operate a pulsation compensating torque for compensating a pulsation component; an arithmetic operation controller configured to control the arithmetic operator (i) to arithmetically operate the pulsation compensating torque in a first cycle in a period that does not include a vertex portion in which the pulsation compensating torque is locally maximal or locally minimal and (ii) to arithmetically operate the pulsation compensating torque in a second cycle, a length of which is shorter than that of the first cycle, in a period that includes the vertex portion; and a torque controller configured to control the electric motor to output a torque including the pulsation compensating torque arithmetically operated by the arithmetic operator.

A control device for an internal combustion engine is provided. The internal combustion engine includes a plurality of cylinders. The internal combustion engine is configured such that when an intake valve of one cylinder on a compression stroke among the plurality of cylinders is open, an intake valve of each of the remainder of the plurality of cylinders is closed. The control device includes an electronic control unit configured to: (i) determine an open-closed state of the intake valve of each of the plurality of cylinders; and (ii) adjust an opening degree of a throttle valve to a first opening degree that is larger than a second opening degree corresponding to an idling operation, when the electronic control unit determines that the intake valve of any one of the plurality of cylinders is open at the time of startup of the internal combustion engine, to reduce compression torque and vibrations.

A control device for a hybrid vehicle is, in the process of stopping an internal combustion engine of the vehicle, capable of making twist angle fluctuation reduction control and crank angle position control mutually compatible. When a request for stopping the internal combustion engine has been issued, twist angle fluctuation reduction control is implemented without implementing crank angle position control, until, in the process of bringing the engine to a stopped state, the rotational speed of the internal combustion engine drops below the resonant rotational speed region of the torsional damper; and, after the rotational speed of the internal combustion engine has dropped below the resonant rotational speed region of the torsional damper in the process of bringing the engine to a stopped state, crank angle position control is implemented without implementing twist angle fluctuation reduction control, until stopping of the internal combustion engine has been completed.

Control device for hybrid vehicle

A stop control apparatus is applied to an internal combustion engine () whose crankshaft () is connected to an input shaft () via a torsional damper (), wherein the direction in which the crankshaft () rotates while the operation of the internal combustion engine () is assumed to be the positively rotating direction, and a state of the torsional angle of the torsional damper () when the crankshaft () is advancing in the positively rotating direction with respect to the input shaft () is assumed to be positive. When a predetermined engine stop condition is satisfied, a stop control for outputting torque from a first MG () such that the crankshaft () decelerates is executed. The timing at which the torque is output from the first MG () is controlled such that the positive peak of the torsional angle of the torsional damper () occurs in the expansion stroke of the internal combustion engine ().

A stop control apparatus for an internal combustion engine is provided with: a motor (MG) configured to output torque to a crankshaft () of the internal combustion engine (); a number-of-revolutions detecting device () configured to detect the number of revolutions of the internal combustion engine; a crank angle detecting device () configured to detect a crank angle of the crankshaft of the internal combustion engine; a motor controlling device () configured to control the motor to output adjusting torque which adjusts the crank angle when the internal combustion engine stops to have a desired value, when the internal combustion engine stops; a throttle valve controlling device () configured to control an opening degree of a throttle valve () to be a predetermined opening degree in an intake stroke immediately before the internal combustion engine stops; and an adjusting torque determining device () configured, to determine the adjusting torque on the basis of the predetermined opening degree and the crank angle when the number of revolutions of the internal combustion engine has a predetermined value. This makes it possible to preferably control the crank angle when the internal combustion engine stops.

A stop control apparatus () for an internal combustion engine performs stop control of a three-or-less cylinder internal combustion engine (). The stop control apparatus for the internal combustion engine is provided with: a determining device () configured to determine a compression stroke immediately before the internal combustion engine stops; and a throttle valve controlling device () configured to control an opening degree of a throttle valve () to be a predetermined opening degree while an intake valve () is closed in all cylinders, in the compression stroke immediately before the internal combustion engine stops, which is determined by the determining device. This reduces an influence of an intake negative pressure in an intake stroke, and makes it possible to preferably control the crank angle when the engine stops, even in the three-or-less cylinder internal combustion engine.
