By fastening, the rotation of the electric motor MG can be transmitted to the engine ENG.
- second path When the engine is started via the path of the second input shaft 35 (hereinafter referred to as “second path”), the second speed stage or the fourth speed stage is established, and the second clutch C2 is further engaged, whereby the electric motor MG Can be transmitted to the engine ENG.
- the rotational speed of the first input shaft 34 is the same as the motor rotational speed Ms. Further, when the first clutch C1 is engaged, the rotational speed of the engine output shaft 2 is the same as the motor rotational speed Ms. Therefore, when the engine is started through the first path, the motor rotation speed Ms is the same as the rotation speed of the engine ENG.
- the second input shaft 35 includes “first input shaft 34”, “third speed drive gear G3 or fifth speed drive gear G5”, “first driven gear Go1 or second driven gear Go2”, and “second speed drive”. It is connected to the electric motor MG via a gear G2 or a 4-speed drive gear G4 ". Further, when the second clutch C2 is engaged, the engine output shaft 2 is connected to the second input shaft 35 via the idle gear train Gi. Therefore, when the engine is started by the second path, the motor rotation speed Ms is shifted and the engine output shaft 2 is rotated, so the motor rotation speed Ms is different from the rotation speed of the engine ENG.
- the motor rotational speed Ms transmitted to the engine ENG in the second speed side connected state or the fourth speed side connected state is obtained, respectively, and it is determined whether or not it is equal to or lower than the idle speed Ei of the engine ENG ( ST106).
- the motor rotational speed Ms at this time is obtained as follows.
- the gear ratio of each gear stage and idle gear train of the automatic transmission 31 is previously stored in the memory of the ECU, and the motor speed Ms transmitted to the engine ENG is determined from the actual speed and gear ratio of the motor MG. Calculate to find.
- the first path and the second path correspond to two paths for transmitting the driving power reduction to the driving wheels in the present invention. Further, in the present invention, the process of steps ST105 and ST106 changes the path connected to the motor from one to the other, and the motor speed transmitted from the motor via the connected path is equal to or lower than the engine idle speed. This corresponds to determining whether or not there is.
- the route is changed (ST107), and the engine start control in the high speed mode (ST104).
- the route is changed, if Ms> Ei in the second speed side connected state, the second speed side connected state is set. If Ms> Ei in the fourth speed side connected state, the fourth speed side connected state is set. To.
- engine start control is performed in the low speed mode (ST110).
- the route is changed (ST111), and the engine in the low speed mode is changed.
- Start control is performed (ST110).
- the engine start control in the low speed mode is the same as step ST4 in FIG.
- This control process ends when the engine start control in the low speed mode and the high speed mode is completed.
- step ST108 and step ST109 described above will be described.
- At least one state of “when the SOC of the storage battery BATT is equal to or lower than the predetermined value ⁇ ”, “when the temperature of the electric motor MG is equal to or higher than the predetermined value ⁇ ”, or “when an abnormality occurs in the electric motor MG” At this time, it is better to change the route, and the engine ENG is started via the second route.
- the predetermined value ⁇ is set to a value that can determine whether or not the value is sufficient to continue EV traveling. That is, when the SOC of the storage battery BATT is equal to or less than the predetermined value ⁇ , it is not sufficient to continue EV traveling, and it is not preferable to apply a large load to the electric motor MG. In this case, in order to reduce the load on the electric motor MG, the engine is started with a gear set lower than the gear currently being traveled.
- the route is changed to the second speed. Since the second speed stage has a larger gear ratio (ratio obtained by dividing the input rotational speed by the output rotational speed) than the third speed stage, the rotational speed transmitted to the engine ENG is 3 even when the rotational speed of the motor MG is the same. It becomes larger than the speed stage.
- the number of revolutions transmitted to the engine ENG can be increased without increasing the load on the electric motor MG.
- opening abnormality an abnormality in which the charging path from the electric motor MG to the storage battery BATT cannot be opened.
- ⁇ Opening abnormality occurs when an abnormality occurs in the contactor (electromagnetic contactor) that opens and closes the current of the electric motor MG and it cannot be opened. That is, when an open abnormality occurs, power generation is always performed during rotation of electric motor MG, and charging is performed regardless of the SOC of storage battery BATT. Therefore, the battery is further charged when the SOC of the storage battery BATT is high, and the possibility of damage to the storage battery BATT due to overcharging increases.
- Whether or not an open abnormality has occurred is determined by determining whether or not the current value of the electric motor MG detected by a current sensor (not shown) is out of a predetermined range. When it is out of the range, it is determined as an abnormal state, and when it is within the range, it is determined as a normal state.
- the route is changed to the fourth speed. Since the gear ratio of the fourth speed stage is smaller than that of the third speed stage, even when the rotation speed of the electric motor MG is the same, the rotation speed transmitted to the engine ENG is larger than that at the third speed stage. Thus, the engine ENG can be started while reducing the SOC of the storage battery BATT.
- the opening abnormality is mentioned as the abnormality of the electric motor MG
- it may be changed to the second path so that the electric motor MG or the storage battery BATT can be prevented from being damaged.
- an even-numbered stage is selected so that the gear ratio becomes small (for example, upshift from the third speed to the fourth speed), and the motor MG
- an even-numbered gear is selected so that the gear ratio is increased (for example, downshift from the third gear to the second gear).
- changing to the second path by the processing of the above steps ST108, ST109, ST111 is the case where the SOC of the electric power source of the electric motor is lower than a predetermined value, and the temperature of the electric motor is higher than the predetermined value or the electric motor is abnormal.
- this corresponds to changing the path connected to the electric motor and starting the engine via the connected path.
- the engine ENG can be started without increasing the load of the motor MG. Further, depending on the state of the electric motor MG and the storage battery BATT, the engine ENG can be started so as to prevent these damages.

ロック機構R1を固定状態とし、第3噛合機構SM3をリバースギヤGRとリバース軸36とを連結した連結状態として、第2クラッチC2を締結させて伝達状態とする。これにより、エンジン出力軸2の駆動力が、第2クラッチC2、アイドルギヤ列Gi、リバースギヤGR、リバース従動ギヤGRa、サンギヤSa、キャリアCa、3速ギヤ列G3及び出力軸33aを介して後進方向の回転として、出力部材33から出力され、後進段が確立される。
所定値αは、EV走行を継続するために充分な値か否かが判別可能な値に設定される。すなわち、蓄電池BATTのSOCが所定値α以下のときは、EV走行を継続するのに充分ではないため、電動機MGに大きな負荷をかけるのが好ましくない状態である。この場合には、電動機MGの負荷を軽減するために、現在走行中の変速段より低い変速段に設定してエンジンを始動する。
一般的に高温の場合には、電動機MGのエネルギー効率が悪くなる。電動機MGの回転軸(第1入力軸34)を回転させるための磁力は、温度が高くなるほど低くなり、電動機MGの出力する駆動力が減少するためである。

前記始動要求は、前記車両の走行速度が所定の始動可能速度より大きいときにあったものとすることを特徴とするエンジン始動制御装置。 - 請求項1~5のいずれか1項に記載の始動制御装置において、
前記ハイブリッド車両は、前記駆動源の動力を変速比が異なる2つの経路により駆動輪に伝達する動力装置を備え、
前記電動機は、前記2つの経路の一方に接続されており、
前記電動機回転数(Ms)が前記内燃機関のアイドル回転数(Ei)以下であると判定した場合には、前記電動機に接続する経路を一方から他方へ変更し、その接続した経路を介して前記電動機から伝達される電動機回転数(Ms)が前記内燃機関のアイドル回転数(Ei)以下であるか否かを判定することを特徴とする始動制御装置。 - 請求項6に記載の始動制御装置において、
前記電動機の電源のSOCが所定値以下の場合と、前記電動機の温度が所定値以上か又は前記電動機が異常の場合との、いずれか一方又は両方が生じたときには、前記電動機に接続する経路を変更し、その接続した経路を介して前記内燃機関を始動させることを特徴とする始動制御装置。
