Abstract

PROBLEM TO BE SOLVED: To provide a hybrid vehicle which can transition to a limp-home mode more safely than ever before upon engine failure, and a control method for the hybrid vehicle.SOLUTION: When a limp-home control part 13 stops diesel engine 5 or limits the output thereof to cause an HEV 1 to transition to a limp-home mode, an ECU 14 causes a clutch 12 for a motor to be brought into an engaged state and causes a motor generator 6 to be rotationally driven to thereby cause the motor generator 6 to share the entirety or a part of drive force transmitted from a transmission 4 to an output shaft 3.

Description

本発明はハイブリッド車両及びその制御方法に関し、更に詳しくは、従来よりも安全にリンプホームモードに移行することができるハイブリッド車両及びその制御方法に関する。   The present invention relates to a hybrid vehicle and a control method thereof, and more particularly to a hybrid vehicle and a control method thereof that can shift to a limp home mode more safely than in the past.

近年の車両には、エンジンやトランスミッションの故障により正常な走行が不可能となった場合には、その故障を拡大させることなく最小限の運転条件での走行を可能にする、いわゆるリンプホームモードが実装されている(例えば、特許文献1を参照)。   Recent vehicles have a so-called limp home mode that makes it possible to run under minimal driving conditions without increasing the failure when normal driving becomes impossible due to engine or transmission failure. It is mounted (for example, refer to Patent Document 1).

エンジンが発生する駆動力の少なくとも一部を、バッテリーを電源とする電動発電機で代替するハイブリッドシステムを備えたハイブリッド車両(以下「HEV」という。)においては、エンジンの故障時には、その故障の程度に応じてエンジンを停止又は出力を制限するリンプホームモードに移行するとともに、ハイブリッドシステム自体を停止させることが行われている。   In a hybrid vehicle (hereinafter referred to as “HEV”) having a hybrid system in which at least a part of the driving force generated by the engine is replaced by a motor generator using a battery as a power source, the extent of the failure when the engine fails Accordingly, the hybrid system itself is stopped while shifting to a limp home mode in which the engine is stopped or the output is limited.

しかしながら、HEVが、特に高速道路での走行中にリンプホームモードに移行すると、HEVが急減速して運転が困難となり、乗員が危険にさらされるおそれがある。   However, when the HEV shifts to the limp home mode particularly during traveling on a highway, the HEV suddenly decelerates and driving becomes difficult, and there is a risk of occupants being in danger.

特開2013−1350号公報JP 2013-1350 A

本発明の目的は、エンジンの故障時において、従来よりも安全にリンプホームモードに移行することができるハイブリッド車両及びその制御方法を提供することにある。   An object of the present invention is to provide a hybrid vehicle capable of shifting to a limp home mode more safely than before in the event of an engine failure and a control method therefor.

上記の目的を達成する本発明のハイブリッド車両は、バッテリーに接続された電動発電機及びエンジンの少なくとも一方を駆動源とするハイブリッドシステムと、前記エンジンの故障診断結果に応じて該エンジンを停止又は出力制限するリンプホーム制御部と、前記ハイブリッドシステム及びリンプホーム制御部を制御する制御手段とを備えたハイブリッド車両において、前記制御手段は、前記リンプホーム制御部が前記エンジンを停止又は出力制限したときは、前記電動発電機に前記ハイブリッド車両の駆動力の全部又は一部を負担させることを特徴とするものである。   The hybrid vehicle according to the present invention that achieves the above object includes a hybrid system that uses at least one of a motor generator and an engine connected to a battery as a drive source, and stops or outputs the engine according to a failure diagnosis result of the engine. In a hybrid vehicle comprising a limp home control unit for limiting and a control unit for controlling the hybrid system and the limp home control unit, the control unit is configured to stop or limit the output of the engine by the limp home control unit. The motor generator bears all or part of the driving force of the hybrid vehicle.

また、上記の目的を達成する本発明のハイブリッド車両の制御方法は、バッテリーに接続された電動発電機及びエンジンの少なくとも一方を駆動源とするハイブリッドシステムを備えたハイブリッド車両の制御方法であって、前記エンジンの故障診断結果に応じて該エンジンを停止又は出力制限したときに、前記電動発電機に前記ハイブリッド車両の駆動力の全部又は一部を負担させることを特徴とするものである。   The hybrid vehicle control method of the present invention that achieves the above object is a hybrid vehicle control method including a hybrid system that uses at least one of a motor generator and an engine connected to a battery as a drive source, When the engine is stopped or output is limited according to the engine failure diagnosis result, the motor generator is caused to bear all or part of the driving force of the hybrid vehicle.

本発明のハイブリッド車両及びその制御方法によれば、エンジンの故障時に電動発電機によりハイブリッド車両の駆動力の全部又は一部を負担するようにしたので、ハイブリッド車両の急減速を回避できるため、従来よりも安全にリンプホームモードへ移行することができる。   According to the hybrid vehicle of the present invention and the control method thereof, since the motor generator bears all or part of the driving force of the hybrid vehicle when the engine fails, it is possible to avoid sudden deceleration of the hybrid vehicle. It is possible to shift to the limp home mode more safely.

本発明の実施形態からなるハイブリッド車両の構成図である。It is a block diagram of the hybrid vehicle which consists of embodiment of this invention. 本発明の実施形態からなるハイブリッド車両の制御方法を説明するフロー図である。It is a flowchart explaining the control method of the hybrid vehicle which consists of embodiment of this invention.

以下に、本発明の実施の形態について、図面を参照して説明する。図1は、本発明の実施形態からなるハイブリッド車両を示す。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a hybrid vehicle according to an embodiment of the present invention.

このハイブリッド車両(以下、「HEV」という。)1は、左右一対の駆動輪2、2に駆動力を伝達する出力軸3に、変速機4を介して連結するディーゼルエンジン5及び電動発電機6と、その電動発電機6にインバータ7を通じて電気的に接続するバッテリー8とを有するハイブリッドシステム9を備えている。変速機4とディーゼルエンジン5との間には、湿式多板クラッチ10及び流体継手11が順に設けられている。また、変速機4と電動発電機6との間には、駆動力を断接するモータ用クラッチ12が介設されている。   This hybrid vehicle (hereinafter referred to as “HEV”) 1 includes a diesel engine 5 and a motor generator 6 that are connected via a transmission 4 to an output shaft 3 that transmits a driving force to a pair of left and right drive wheels 2 and 2. And a hybrid system 9 having a battery 8 electrically connected to the motor generator 6 through an inverter 7. A wet multi-plate clutch 10 and a fluid coupling 11 are sequentially provided between the transmission 4 and the diesel engine 5. A motor clutch 12 that connects and disconnects the driving force is interposed between the transmission 4 and the motor generator 6.

更に、HEV1には、リンプホーム制御部13が装備されている。このリンプホーム制御部13は、ディーゼルエンジン5の故障診断を行い、その故障の程度に基づいてHEV1をリンプホームモードへ移行させる機能を有している。   Further, the HEV 1 is equipped with a limp home control unit 13. The limp home control unit 13 has a function of performing a failure diagnosis of the diesel engine 5 and shifting the HEV 1 to the limp home mode based on the degree of the failure.

具体的なリンプホームモードの内容としては、ディーゼルエンジン5に火災が発生したような重度の故障の場合にはエンジンが停止される一方で、ディーゼルエンジン5の部品が損傷したような軽度の故障の場合には、エンジン出力が予め設定されたレベルに制限される。   As a specific content of the limp home mode, in the case of a severe failure such as a fire occurring in the diesel engine 5, the engine is stopped, while a minor failure such as a damaged part of the diesel engine 5 is detected. In some cases, the engine output is limited to a preset level.

上記のハイブリッドシステム9及びリンプホーム制御部13は、制御手段であるECU14に信号線(一点鎖線で示す)を通じて接続されている。   The hybrid system 9 and the limp home control unit 13 are connected to an ECU 14 as control means through a signal line (indicated by a one-dot chain line).

なお、図1ではリンプホーム制御部13とECU14を別体としているが、両者を一体的に構成しても良い。   In FIG. 1, the limp home control unit 13 and the ECU 14 are separated from each other, but both may be integrally configured.

このようなHEV1におけるECU14による制御方法を、図2に基づいて以下に説明する。   The control method by ECU14 in such HEV1 is demonstrated below based on FIG.

ECU14は、リンプホーム制御部13を通じて、HEV1がリンプホームモードに移行したか否かを判定し(S10)、リンプホームモードに移行してディーゼルエンジン5が停止又は出力制限された場合には、モータ用クラッチ12を接続し、かつ電動発電機6を回転駆動させることで(S20)、変速機4から出力軸3に伝達される駆動力の全部又は一部をアシストする(S30)。   The ECU 14 determines whether or not the HEV 1 has shifted to the limp home mode through the limp home control unit 13 (S10), and when the diesel engine 5 is stopped or the output is limited by shifting to the limp home mode. The clutch 12 is connected and the motor generator 6 is rotationally driven (S20), thereby assisting all or part of the driving force transmitted from the transmission 4 to the output shaft 3 (S30).

この電動発電機6によるアシストの大きさは、ディーゼルエンジン5の故障の程度に依存し、例えばエンジン停止時には、電動発電機6の出力限界でアシストする一方で、エンジン出力の制限時には、ディーゼルエンジン5の出力がリンプホームモードで予め設定されたレベルを維持できるようにアシストする。   The magnitude of the assist by the motor generator 6 depends on the degree of failure of the diesel engine 5. For example, when the engine is stopped, the assist is performed at the output limit of the motor generator 6, while when the engine output is limited, the diesel engine 5 Assists so that the output can be maintained at a preset level in the limp home mode.

このようにすることで、エンジンの故障時にHEV1の急減速を回避できるので、従来よりも安全にリンプホームモードに移行することができるのである。また、リンプホームモード中においては、電動発電機6の駆動力でHEV1を運転するので、更に乗員の安全性を向上することができる。   In this way, since the HEV 1 can be prevented from suddenly decelerating when the engine fails, it is possible to shift to the limp home mode more safely than in the past. Further, during the limp home mode, the HEV 1 is driven by the driving force of the motor generator 6, so that the safety of the occupant can be further improved.

本発明のハイブリッド車両及びその制御方法は、HEV1の急減速が特に問題となる高速道路での走行時、例えば60km/h(一般道における法定最高速度)以上の速度での走行時において好適に実施される。   The hybrid vehicle of the present invention and the control method thereof are suitably implemented when traveling on a highway where sudden deceleration of HEV1 is particularly problematic, for example, traveling at a speed of 60 km / h (the legal maximum speed on ordinary roads) or higher. Is done.
