Problems solved by technology
[0006] However, in the hybrid vehicle control device of the prior art described above, when traveling on an uphill road, only the regenerative torque of the electric motor is relatively reduced, or the assist amount of the electric motor to the internal combustion engine is increased. When the driving time on the road is long, or when the uphill slope of the uphill road is relatively steep, etc., the electric energy required to drive the electric motor may be insufficiently stored in the accumulator, resulting in The problem that the expected uphill driving performance cannot be ensured

Embodiment Construction
[0056] Hereinafter, a control device for a hybrid vehicle according to an embodiment of the present invention will be described with reference to the drawings.
[0057] The hybrid vehicle 1 of the present embodiment is as figure 1 Shown is a parallel hybrid vehicle in which an internal combustion engine (ENG) 11 , a motor (MOT) 12 , and a transmission (T / M) 13 are connected in series. The driving forces of both the internal combustion engine 11 and the motor 12 are distributed and transmitted to left and right drive wheels W, W through a transmission 13 and a differential (not shown). When the hybrid vehicle 1 decelerates, when the driving force is transmitted from the driving wheel W side to the motor 12 side, the motor 12 functions as a generator, generates so-called regenerative braking force, and recovers the kinetic energy of the vehicle body as electrical energy. Corresponding to the operating state of the hybrid vehicle 1 , the motor 12 is driven by the output of the i...

A control device for a hybrid vehicle having an internal combustion engine, a generator motor, an electricity storage device, and driving force assist means. The control device has switch means that appropriately selects from and switches between travel ranges including at least a normal travel range and a charge priority range in which charging to the electricity storage device is prioritized. The control device also has threshold value increasing means that, when the charge priority range is selected by the selection means, increases a specific determination threshold value to a level higherthan that when the normal travel range is selected by the switch means.
Description
technical field [0001] The present invention relates to a control device for a hybrid vehicle. [0002] This application uses Japanese Patent Application No. 2007-183462 as a basic application, and takes the content here. Background technique [0003] Conventionally, for example, a hybrid vehicle having an internal combustion engine and an electric motor as driving sources and transmitting at least either the driving force of the internal combustion engine or the electric motor to the driving force has been known (for example, refer to Patent Document 1). When driving on an uphill road, the regenerative torque of the electric motor is relatively reduced, thereby preventing excessive deceleration feeling and ensuring the expected drivability. [0004] In such a hybrid vehicle, for example, when moving from a flat road to an uphill road, etc., when the accelerator operation amount of the driver exceeds a predetermined threshold, the electric motor is powered on, and the drivi...
