Problems solved by technology

By controlling according to this method, the torque of the engine is limited to a certain extent, so that even if the driver depresses the accelerator pedal to the bottom, only output power lower than the maximum torque can be output (for example, refer to Patent Document 1).

Embodiment Construction

[0035] Below, refer to Figure 1 to Figure 5 A hybrid vehicle according to an embodiment of the present invention will be described.

[0036] figure 1 It is a block diagram showing a configuration example of the hybrid vehicle 1 . The hybrid car 1 is an example of a vehicle. The hybrid vehicle 1 is driven by an engine (internal combustion engine) 10 and / or an electric motor 13 via a transmission device of a semi-automatic transmission, and can implement output power limitation that limits torque output from the engine 10 and / or electric motor 13 . In addition, the so-called semi-automatic transmission refers to a transmission that has the same configuration as a manual transmission but can automatically perform a shifting operation.

[0037] The hybrid vehicle 1 is configured to include an engine 10, an engine ECU (Electronic Control Unit, electronic control unit) 11, a clutch 12, an electric motor 13, an inverter (inverter) 14, a battery 15, a transmission 16, an electric ...

Abstract

To improve the drivability of an automobile at the time of transmission which restricts a torque of an engine, a hybrid automobile is structured which performs transmission control for performing control so that an output restriction is temporarily released in a step of restoring a torque that is reduced once in neutral at the time of transmission during the output restriction by an output restriction control unit and a torque by a motor is added to the torque of the engine.

Description

technical field [0001] The invention relates to a speed change control device, a hybrid electric vehicle and a speed change control method. Background technique [0002] As one method for reducing exhaust gas emitted from an automobile, there is a method of limiting the torque of the engine relative to the torque requested by the driver. By controlling according to this method, the torque of the engine is limited, so that even if the driver depresses the accelerator pedal to the bottom, only an output lower than the maximum torque can be output (for example, refer to Patent Document 1). [0003] [Prior Art Literature] [0004] 【Patent Literature】 [0005] Patent Document 1: Japanese gazette, Japanese Patent Laid-Open No. 2006-280049 Contents of the invention [0006] When a car shifts gears, the engine torque is temporarily reduced from the gear before the shift to neutral, and then the gear is shifted to the gear after the shift to restore the temporarily reduced engin...
