- the present invention relates to control of a vehicle including an internal combustion engine and a rotating electric machine, and more particularly to control of both vehicles capable of shifting in a manual shift mode by a driver's selection.
- a hybrid vehicle is a vehicle equipped with an electric motor in addition to a conventional internal combustion engine as a power source for both vehicles.
- a technique that enables shifting in the manual shift mode according to the driver's selection is disclosed in, for example, Japanese Patent Application Laid-Open No. 2000/062: 569.
- the shift device disclosed in Japanese Patent Laid-Open No. 2 0 6-6 6:59 is a hybrid in which an engine, a first electric motor, and a second electric motor connected to a drive wheel are connected by a planetary gear device. "I" control the vehicle.
- This shift palm is equipped with a shift lever that is not operated to select multiple shift positions.
- This shift lever is provided so that it can be manually operated to the parking position, reverse position, neutral position, automatic forward shift position (D position), and forward manual shift position (M position).
- M position is provided with upshift position “+” and downshift position “ ⁇ ” in the 3 ⁇ 4two front-back direction, and the shift lever is operated to upshift position “10” or downshift position: “1”. Then, it can be switched to either “D” range or “L” range.
- the gear ratio is controlled so as not to exceed the gear ratio on the highest speed side of the gear range.

- This control unit has a detection unit that detects that the shift mode of the automatic shift mode and the manual shift mode is selected by the driver, and the automatic shift mode when the manual shift mode is selected. Compared to the case where is selected, control for controlling the running source so as to change the idling speed of the internal combustion engine is required.
- the gear ratio is selected by the driver while traveling in the manual transmission mode.
- the rotational speed of the internal combustion engine is controlled by the internal combustion engine or the rotating electrical machine to a rotational speed corresponding to the speed ratio selected by the driver.
- the output torque of the rotating electrical machine is controlled to be substantially zero, and the internal combustion engine is controlled to the idling state, even during traveling in the manual shift mode.
- the driver t is selected from the above and is not controlled to the rotational speed according to the speed ratio, but may be controlled to the idle rotational speed only by the internal combustion engine. Therefore, in manual transmission mode, the internal combustion engine: ⁇ : the number of revolutions is selected by the driver.
- the idle speed of the internal combustion engine changes, and the vehicle may be shocked. Therefore, when the manual transmission mode is selected, the idle speed of the internal combustion engine is changed compared to when the automatic transmission mode is selected. For example, the idle speed of the internal combustion engine is changed to a rotation fC corresponding to the gear ratio selected by the driver. Therefore, in the manual transmission mode, the internal combustion engine speed is low and the occurrence of shock can be suppressed. As a result, in a vehicle capable of shifting in the manual shift mode using the internal engine and the rotating electrical machine connected to the internal combustion engine as a travel source, it is possible to suppress the shock of the vehicle that occurs in the manual shift mode.

- the control unit controls the traveling source so as to change the idle rotational speed based on the lower limit rotational speed.
- the lower limit rotational speed of the internal B engine is calculated based on the vehicle speed and the manual shift speed. Based on the calculated lower limit speed, the idle speed is changed. Therefore, the difference between the minimum speed and the idle speed can be reduced. As a result, the rotational speed of the internal combustion engine can be stabilized even if the engine speed is switched from the state where the rotational speed of the internal combustion engine is controlled to the lower P ⁇ rotational speed to the state where the rotational speed is controlled to the idle rotational speed.
- control unit is operable when the manual transmission is selected.
- the travel source is controlled to change the dollar rotation speed to a value corresponding to the lower limit rotation speed.
- the idle rotation speed is changed to a value corresponding to the lower limit rotation speed. Therefore, the rotational speed of the internal combustion engine can be stabilized near the lower limit rotational speed.
