## Abstract

A control device of a hybrid vehicle has an engine and an electric motor, the hybrid vehicle being configured to perform motor running using only the electric motor for running and engine running using at least the engine for running, the control device comprising: a first starting portion starting the engine by using the electric motor; and a second starting portion starting the engine without using the electric motor, the control device being configured to expand a range of performing the motor running when the engine is started by the second starting portion as compared to when the engine is started by the first starting portion.

## Claims

### Claim at position 1

1-4. (canceled)

### Claim 5

A control device of a hybrid vehicle having an engine and an electric motor, the hybrid vehicle being configured to perform motor running using only the electric motor for running and engine running using at least the engine for running, the control device comprising: a first starting portion starting the engine by using the electric motor; and a second starting portion starting the engine without using the electric motor,
the control device being configured to expand a range of performing the motor running when the engine is started by the second starting portion as compared to when the engine is started by the first starting portion.

### Claim 6 (depends on 5)

The control device of a hybrid vehicle of claim 5, wherein
the second starting portion injects fuel into a cylinder of the engine during stop of rotation and causes an explosion to start the engine, and wherein
if it is determined that a next engine start is performed by the second starting portion during stop of rotation of the engine, the range of performing the motor running is expanded.

### Claim 7 (depends on 5)

The control device of a hybrid vehicle of claim 5, wherein
the first starting portion starts the engine while the engine is rotationally driven by the electric motor, and wherein
when a smaller output torque of the electric motor is required for rotationally driving the engine, the range of performing the motor running is more expanded.

### Claim 8 (depends on 5)

The control device of a hybrid vehicle of claim 5, comprising a clutch connecting/disconnecting a power transmission path between the engine and the electric motor, wherein
the motor running refers to running with only the electric motor used as a drive force source for running while the clutch is released, wherein
the first starting portion starts the engine while the clutch is controlled toward engagement, and wherein
the second starting portion starts the engine while the clutch is kept released.

### Claim 9

A control device of a hybrid vehicle having an engine and an electric motor, the hybrid vehicle being configured to perform motor running using only the electric motor for running and engine running using at least the engine for running, the control device comprising: a first starting portion starting the engine by using the electric motor; and a second starting portion injecting fuel into a cylinder of the engine during stop of rotation and causing an explosion to start the engine,
the control device being configured to expand a range of performing the motor running when the engine is started by the second starting portion as compared to when the engine is started by the first starting portion.

### Claim 10

A control device of a hybrid vehicle having an engine and an electric motor, the hybrid vehicle being configured to perform motor running using only the electric motor for running and engine running using at least the engine for running, the control device comprising: a first starting portion starting the engine by using the electric motor; and a second starting portion starting the engine by using a starter motor,
the control device being configured to expand a range of performing the motor running when the engine is started by the second starting portion as compared to when the engine is started by the first starting portion.
