Abstract

PROBLEM TO BE SOLVED: To shorten a time required for an internal combustion engine starting, to inhibit a body vibration caused by a twisting resonance of a motive power transmission system and reduce a power consumption in a hybrid vehicle having a motive power device provided with an internal combustion engine and an electric motor. SOLUTION: When a starting of an internal combustion engine is instructed (t=0), a motoring by an electric motor is started. When a rotation speed of the internal combustion engine arrives at an ignition control starting speed Net, a fuel supply and an ignition control are executed. A speed raising rate is enhanced as shown by a solid line in Figure and a passing time at a resonance speed area Net is shortened (t2<t1) by a torque by the internal combustion engine itself and a torque by the electric motor. A time until the internal combustion engine independently starts to rotate is shortened and a power consumption is also inhibited.

2. Description of the Related Art Some hybrid vehicles having two types of prime movers, an internal combustion engine and an electric motor, have been put into practical use for driving vehicles. In such a hybrid vehicle, at a low speed, the internal combustion engine having relatively low efficiency at this time is stopped, and the vehicle is driven only by the electric motor. When the speed increases, the internal combustion engine is started, and the vehicle is driven by only the internal combustion engine or both prime movers. At this time, the internal combustion engine is started by motoring with an electric motor, and when the internal combustion engine reaches a predetermined rotation speed, ignition control for performing fuel supply and ignition control is executed. Conventionally, the rotation speed at which this ignition control is performed is slightly lower than the idle rotation speed of the internal combustion engine.

[0003] An example of a hybrid vehicle that performs such start control of an internal combustion engine is described in Japanese Patent Application Laid-Open No. Hei 10-82332. In the vehicle described in this publication,
The power transmission system is provided with a torsional damper, and the torsional damper absorbs rotation speed and torque fluctuations of the internal combustion engine. The resonance speed of the power transmission system is set outside the operating speed range of the internal combustion engine, that is, equal to or lower than the idle rotation speed, by adjusting a torsional damper or the like. Therefore, when the internal combustion engine is to be started, the motoring passes through the resonance speed range of the torsional damper, and thereafter, the ignition control is performed.

In order to solve the above-mentioned problems, a method for starting an internal combustion engine of a hybrid vehicle according to the present invention performs motoring by an electric motor and controls ignition at a speed lower than a resonance speed of a power transmission system. Is started, and the internal combustion engine is accelerated to near the idling rotational speed by motoring while maintaining the ignition control.

[0007] The acceleration by the internal combustion engine itself and the acceleration by the motoring increase the rotation speed faster and shorten the time required to pass through the resonance speed range. Thereby, it is possible to suppress the resonance of the power transmission system from inducing the vehicle body vibration.

Further, even when ignition control is performed at a speed lower than the resonance speed, the ignition control can be started at a speed exceeding the resonance speed when the internal combustion engine is at a low temperature where ignition does not actually occur. At such a low temperature, even if the ignition control is performed, the ignition does not occur, the rotation speed does not increase, and unburned gas may be generated.
Therefore, at low temperatures, the ignition control is performed after the motoring is accelerated to a rotational speed at which the starting conditions are sufficiently satisfied.

Since the efficiency of the internal combustion engine 10 is low in a low speed range, the operation is stopped at this time, and the vehicle is driven only by the electric motor 12. When the vehicle speed is high to some extent, driving by the internal combustion engine 10 is performed to suppress power consumption. With only the output of the internal combustion engine 10,
When the required driving force cannot be achieved, the electric motor 12 is also driven to drive the vehicle by both.

FIG. 2 shows an internal combustion engine 1 characteristic of this embodiment.
It is a figure for explaining the starting method of 0. The horizontal axis represents time t, and the vertical axis represents the rotation speed Ne of the internal combustion engine. In the conventional control, when the start control of the internal combustion engine 10 is started (t = 0), the internal combustion engine 10 is motored, and when the rotation speed Ne reaches the ignition start speed Nes, the ignition control is started. . Thereafter, the idle speed Nei or the rotation speed at which the required output is obtained is controlled.
In this conventional control, the resonance speed range N
Therefore, there is a problem that the time t1 when the vehicle passes through er is relatively long, and this resonance vibrates the vehicle body, and the occupant may feel uncomfortable. In order to shorten the passage time in the resonance speed range Ner, the output of the electric motor 12 can be increased to increase the speed of the internal combustion engine 10, but in this case, there is a problem that the power consumed increases.

In this embodiment, the resonance speed range Ner
At a lower rotation speed Net, ignition control is started. Due to the driving force by the motoring and the driving force of the internal combustion engine 10 itself, its rotation speed Ne rapidly increases as shown by a solid line in the figure. As a result, the passage time in the resonance speed range is shortened to time t2, and the speed range can be escaped before the influence of the power transmission system resonance becomes significant. Also,
Since the time required for the internal combustion engine 10 to reach the idle rotation speed Nei is shortened, power consumption for motoring can be reduced. If the motoring of the electric motor 12 and the ignition control of the internal combustion engine 10 can attain a sufficient acceleration, the output of the electric motor 12 for the motoring can be suppressed. In this case, power consumption can be further suppressed.

Further, the rotation speed at the start of ignition can be changed by using the temperature of the internal combustion engine 10. As the temperature of the internal combustion engine 10, for example, a cooling water temperature, an exhaust catalyst temperature, or the like can be used. Conventionally used sensors can be used as sensors for detecting these temperatures. Further, the temperature of the internal combustion engine at the present time can be determined from the elapsed time since the last stop of the engine. In this case, a timer is provided in the control unit 28 for measuring an elapsed time after the engine stop command is issued. When the internal combustion engine 10 is cold, at a low rotational speed, the supplied fuel may not ignite even if the ignition is controlled, and at this time, unburned gas may be discharged. Therefore, in such a cold state, the ignition control start point N
In et, the ignition control is not started, and the ignition control is performed after reaching a speed exceeding the resonance speed range Ner, for example, the conventional ignition control start point Nes.
