Problems solved by technology

[0003] However, in the control device according to one example of the above-mentioned prior art, a plurality of circuits are required to change the torque characteristics of the electric motor that starts the internal combustion engine, so that there is a problem of complicating the device configuration and increasing the size of the device.
[0004] Furthermore, when continuous discharge is performed in a state where the temperature of the battery is low or the remaining capacity is reduced, an excessive voltage drop occurs, the electric power supplied to the motor decreases, and it may be difficult to output the desired torque required for starting the internal combustion engine.
In addition, there is a problem that the voltage drop at the height of the battery promotes the deterioration of the battery

Embodiment Construction

[0047] Next, a control device for an internal combustion engine according to an embodiment of the present invention will be described with reference to the drawings.

[0048] The internal combustion engine control device according to this embodiment of the invention is mounted on a vehicle such as a parallel hybrid vehicle in which an internal combustion engine E, an electric motor M, and a transmission T / M are connected in series, as shown in FIG. 1 , for example. The driving force of both the internal combustion engine E and the electric motor M is transmitted to the driving wheels of the vehicle through a differential that distributes the driving force between the left and right driving wheels (front wheels or rear wheels) from a transmission T / M such as a continuously variable transmission (CVT), Also, when the hybrid vehicle decelerates and the driving force is transmitted from the drive wheels to the motor M, the motor M functions as a motor to generate so-called regenera...

Abstract

The invention provides a control device which is used for an internal combustion engine which can be started by an electric driving motor to which an accumulator supplies the power; wherein, the invention is provided with a starting mode selection part which can take a first mode or a second mode as the starting mode of the internal combustion engine and a control device which sets the output mode when the power is output from the accumulator to the motor. The control device can set a smooth mode which continuously outputs a specified power correspondingly to the first mode and a pulse mode which outputs the power with the amplitude change more than the specified amplitude correspondingly to the second mode and can take one of the two modes as the output mode.

Description

technical field [0001] The invention relates to a control device for an internal combustion engine. Background technique [0002] Currently, it is known to change the amount of magnetic flux corresponding to the number of windings of the motor by using a plurality of circuits according to the output voltage of the battery in order to improve the startability of the internal combustion engine when the battery capacity is reduced, for example, at extremely low temperatures or when the battery is degraded. A control device for controlling torque characteristics of a motor at a predetermined voltage (for example, refer to JP-A-2005-20795). [0003] However, in the control device of one example of the above-mentioned prior art, it is necessary to have a plurality of circuits in order to change the torque characteristic of the electric motor that starts the internal combustion engine, and there is a problem that the device configuration is complicated and the device size is also i...
