- the absolute value of the change speed of the accelerator pedal opening (change speed
- ) is equal to or greater than a predetermined value TH1
- ) of the deviation between the previous read value and the current read value of the accelerator pedal opening is equal to or greater than the predetermined value TH2 (FIG. 3).
- S106: YES) is provided ([0037]). It is said that only one of the change rate
- JP 2005-219580 A focuses on the absolute value of the change rate of the accelerator pedal opening (change rate
- is used only as one of the conditions for performing the control for starting the addition of the driving force to the inner turning wheel after the application of the driving force to the outer turning wheel is started.
- of the accelerator pedal opening directly reflects the operation of the accelerator pedal, that is, the driver's intention of acceleration / deceleration (or the future acceleration / deceleration state of the vehicle).

- JP 5-2005-219580 A has room for improvement from the viewpoint of vehicle attitude control or operation performance (responsiveness to accelerator pedal operation, etc.) during acceleration turning.
- the present invention has been made in consideration of the above-described problems, and an object of the present invention is to provide a vehicle capable of improving the attitude control or operation performance of the vehicle during accelerated turning.

- the vehicle further comprises a turning control device that adjusts a power difference between the left driving wheel and the right driving wheel based on a time differential value of the required driving power amount.
- the power difference between the left and right drive wheels is adjusted based on the required turning amount and the time differential value of the required drive power amount. For this reason, even with the same required turning amount, the power difference between the left and right drive wheels varies depending on the time differential value of the required drive power amount. Therefore, for example, when the power difference between the left and right drive wheels is increased as the time differential value of the required drive power amount increases, the vehicle (vehicle body) can be easily turned stably. This is particularly noticeable in a low speed region where the response of the behavior of the vehicle to steering is low. Therefore, the above control makes it possible to make the vehicle posture more stable or to increase the responsiveness to the driver's intention (high-speed turning).
- the turning control device may increase the power difference as the time differential value of the required drive power amount increases. Or the said turning control apparatus may make the said power difference small, so that the time differential value of the said request

- the power difference may be adjusted by controlling the power of the first prime mover and the second prime mover.
- the power difference between the left and right drive wheels is adjusted by controlling the power of the first prime mover and the second prime mover.
- the prime mover is connected to each of the left and right drive wheels, so that the outputs of the left and right drive wheels can be controlled independently.
- the first prime mover and the second prime mover are electric motors capable of generating power in the forward direction and the reverse direction of the vehicle, respectively, and the turning control device includes the vehicle of the first prime mover and the second prime mover.
- the power difference may be adjusted by generating power in the forward direction on the one corresponding to the outer ring in the turning direction and generating power in the reverse direction on the one corresponding to the inner ring.
- the turning control device adjusts the power difference between the left and right drive wheels by the first prime mover and the second prime mover connected to the left and right drive wheels.
- many electric motors can control power with high response and high definition. For this reason, with the above-described configuration, it is possible to generate a power difference between the left and right drive wheels with high response and high definition.
- the left driving wheel and the right motor Adjust the power difference from the drive wheels. For this reason, it is possible to flexibly set the power difference without being restricted by the fact that the power of both the left and right drive wheels must be in the forward direction (positive value). Therefore, it is possible to further improve the attitude control or operation performance of the vehicle according to the scene.
- the prime mover and the left drive wheel are connected via a first power transmission mechanism
- the prime mover and the right drive wheel are connected via a second power transmission mechanism
- the turning control device is configured to receive the request.
- the power difference may be adjusted by controlling the first power transmission mechanism and the second power transmission mechanism based on a time differential value of the driving power amount.
- the power difference between the left and right drive wheels can be adjusted without waiting for a change in the output of the prime mover based on the time differential value of the required drive power amount.
- the first power transmission mechanism is switchable between a connected state in which power is transmitted between the prime mover and the left drive wheel and a disconnected state in which power is shut off between the prime mover and the left drive wheel.
- the second power transmission mechanism includes a connection state in which power is transmitted between the prime mover and the right drive wheel, and a cutoff state in which power is shut off between the prime mover and the right drive wheel.
- the turning control device includes a first intermittent means and a second intermittent means based on a time differential value of the required drive power amount. The power difference may be adjusted by switching.
- the turning control device adjusts the power difference between the left and right drive wheels by connecting / disconnecting the first intermittent means and the second intermittent means. Thereby, it becomes possible to adjust the power difference between the left and right drive wheels by connecting and disconnecting the first intermittent means and the second intermittent means. For this reason, it becomes possible to generate the power difference between the left and right drive wheels with high responsiveness.
- the power difference between the left and right drive wheels based on the time differential value of the required drive power amount becomes small at high vehicle speeds. For this reason, it becomes possible to prevent the behavior of the vehicle from becoming unstable due to an excessive power difference between the left and right drive wheels at a high vehicle speed.
- the turning control device may reduce the power difference when the required turning amount is smaller than when the required turning amount is large when the time differential values of the requested driving power amount are equal.
- the required turning amount is small, the power difference between the left and right driving wheels based on the time differential value of the required driving power amount becomes small. For this reason, for example, when the steering wheel is removed due to road swell or dredging, or when the driver performs fine steering, the power difference between the left and right drive wheels is excessively generated and the behavior of the vehicle becomes It becomes possible to prevent disturbance.
- the turning control device is configured to add an addition power added to the power of the outer wheel in the turning direction of the vehicle of the left driving wheel and the right driving wheel and a subtraction power subtracted from the power of the inner wheel of the required driving power amount.
- the absolute value of the addition power and the absolute value of the subtraction power may be equalized by calculating based on the time differential value.

Abstract
Description
A.構成
A-1.車両10の駆動系
図1は、本発明の一実施形態に係る車両10の駆動系及びその周辺の概略構成図である。図1に示すように、車両10は、車両10の前側に直列配置されたエンジン12及び第1走行モータ14と、車両10の後ろ側に配置された第2走行モータ16及び第3走行モータ18と、高圧バッテリ20(以下「バッテリ20」ともいう。)と、第1~第3インバータ22、24、26と、駆動電子制御装置28(以下「駆動ECU28」という。)とを有する。
[2-1.概要]
図2は、各種センサと駆動ECU28の機能ブロックとを示すブロック図である。図3は、左右後輪36a、36bのうち外輪についてのフィードフォワード制御用トルクの一例を示す図である。駆動ECU28では、図2に示す各ブロックの機能をプログラム処理する。但し、必要に応じて、駆動ECU28の一部をアナログ回路又はデジタル回路に置換してもよい。
車速センサ50は、車両10の車速V[km/h]を検出してFF制御部70、72及びFB制御部80に出力する。舵角センサ52は、ハンドル62の舵角θst[度]を検出してFF制御部70、72及びFB制御部80に出力する。横Gセンサ54は、車両10(車体)に掛かる横加速度Glat[m/s2]を検出してFF制御部70及びFB制御部80に出力する。
(2-3-1.舵角比例FF制御部70)
舵角比例FF制御部70は、舵角比例フィードフォワード制御(以下「舵角比例FF制御」という。)を実行する。舵角比例FF制御では、舵角θst及びこれに伴う横加速度Glatに対応して駆動輪(ここでは、後輪36a、36b)のトルク(駆動力)を制御する。
AP微分FF制御部72は、アクセルペダル微分フィードバック制御(以下「AP微分FF制御」という。)を実行する。AP微分FF制御では、アクセルペダル開度θapの時間微分値である変化速度Vap[度/sec]に対応して駆動輪(ここでは、後輪36a、36b)のトルク(駆動力)を制御する。
第1加算器74は、FF制御部70からのトルクTff1lとFF制御部72からのトルクTff2lとの和(以下「フィードフォワード合計トルクTff_total_l」又は「FF合計トルクTff_total_l」という。)を算出する。
ローパスフィルタ78は、左後輪36a用のFF合計トルクTff_total_lのうち低周波数成分のみを通過させて第1減算器82に出力する。また、ローパスフィルタ78は、右後輪36b用のFF合計トルクTff_total_rのうち低周波数成分のみを通過させて第2減算器84に出力する。これにより、FF合計トルクTff_totalの急激な変化を避けることが可能となる。その結果、AP微分トルクTff2の急激な増加に対する運転者の違和感を避けることが可能となる。
FB制御部80は、フィードバック制御(以下「FB制御」という。)を実行する。FB制御では、車両10の旋回時における駆動輪(ここでは、後輪36a、36b)のスリップを避けるように駆動輪のトルク(駆動力)を制御する。
第1減算器82は、ローパスフィルタ78からのFF合計トルクTff_total_lとFB制御部80からのFBトルクTfblとの差(以下「合計トルクTtotal_l」又は「トルクTtotal_l」という。)を算出する。第2減算器84は、ローパスフィルタ78からのFF合計トルクTff_total_rとFB制御部80からのFBトルクTfbrとの差(以下「合計トルクTtotal_r」又は「トルクTtotal_r」という。)を算出する。以下では、合計トルクTtotal_l、Ttotal_rを「合計トルクTtotal」又は「トルクTtotal」と総称する。
図3には、左右後輪36a、36bのうち外輪についての舵角比例トルクTff1、AP微分トルクTff2及びFF合計トルクTff_totalの一例が示されている。図3からわかるように、アクセルペダル64が踏み込まれると、舵角比例トルクTff1及びAP微分トルクTff2が増加する。この際、舵角比例トルクTff1は、比較的立ち上がりが遅い。このため、舵角比例トルクTff1よりも立ち上がりが速いAP微分トルクTff2を加えることで、FF合計トルクTff_total全体としての立ち上がりを速めることが可能となる。
B-1.AP微分FF制御の流れ
図4は、AP微分FF制御のフローチャートである。図5は、図4のAP微分FF制御を用いた場合の各種データの一例を示す図である。図5において、破線は、所定の車速V及び舵角θstである場合のデータを示し、実線は、破線と同じ車速V且つ破線よりも大きい舵角θstである場合のデータを示す。また、図5は、定速走行をしている状態において、時点t1でアクセルペダル64を強く踏み込んだ場合のデータを示している。
図6は、AP微分FF制御を用いる場合と用いない場合の出力の一例を示す図である。図6では、本実施形態(すなわち、舵角比例FF制御及びAP微分FF制御の両方を行う場合)のトルク差ΔTと、比較例のトルク差ΔTを示している。比較例では、舵角比例FF制御を行うが、AP微分FF制御を行わない。
以上のように、本実施形態によれば、舵角θst(要求旋回量)とAP開度θapの変化速度Vap(要求駆動動力量の時間微分値)とに基づいて左右後輪36a、36b(左右駆動輪)のトルク差ΔT(動力差)を調整する(図2、図4)。このため、同じ舵角θstでも、変化速度Vapによって左右後輪36a、36bのトルク差ΔTが変わる。従って、変化速度Vapが高いほど左右後輪36a、36bのトルク差ΔTを大きくする場合、車両10(車体)を安定して旋回させ易くなる。このことは、特に、操舵に対する車両10の挙動の応答性が低い低速領域で顕著である。従って、上記制御により、車両10の姿勢がより安定し又は運転者の意思(高速旋回)に対する応答性を高めることが可能となる。
なお、本発明は、上記実施形態に限らず、本明細書の記載内容に基づき、種々の構成を採り得ることはもちろんである。例えば、以下の構成を採用することができる。
上記実施形態では、自動四輪車である車両10について説明した(図1)。しかしながら、例えば、舵角θstに加えて、AP開度θapの変化速度Vapに基づいて左後輪36a(左駆動輪)及び右後輪36b(右駆動輪)のトルク差ΔT(動力差)を調整する観点からすれば、これに限らない。例えば、自動三輪車及び自動六輪車のいずれであってもよい。
図7は、本発明の第1変形例に係る車両10Aの駆動系及びその周辺の概略構成図である。車両10Aでは、上記実施形態に係る車両10の前輪駆動装置34及び後輪駆動装置38の構成が反対になっている。すなわち、車両10Aの前輪駆動装置34aは、車両10Aの前側に配置された第2及び第3走行モータ16a、18aを備える。また、車両10Aの後輪駆動装置38aは、車両10Aの後ろ側に直列配置されたエンジン12a及び第1走行モータ14aを備える。
図8は、本発明の第2変形例に係る車両10Bの駆動系及びその周辺の概略構成図である。車両10Bでは、エンジン12からの駆動力(以下「駆動力Feng」という。)を前輪32a、32b及び後輪36a、36bに伝達する。これにより、前輪32a、32b(主駆動輪)に加え、後輪36a、36b(副駆動輪)を駆動輪とする。なお、前記実施形態(図1)と同様、エンジン12にモータ14が接続されてもよい。
図9は、本発明の第3変形例に係る車両10Cの駆動系及びその周辺の概略構成図である。第2変形例に係る車両10Bと同様、車両10Cでは、エンジン12からの駆動力(駆動力Feng)を前輪32a、32b及び後輪36a、36bに伝達する。これにより、前輪32a、32b(主駆動輪)に加え、後輪36a、36b(副駆動輪)を駆動輪とする。車両10Bと同一の構成要素については、同一の参照符号を付して説明を省略する。なお、前記実施形態(図1)と同様、エンジン12にモータ14が接続されてもよい。
上記実施形態では、第1~第3走行モータ14、16、18を3相交流ブラシレス式としたが、これに限らない。例えば、第1~第3走行モータ14、16、18を3相交流ブラシ式、単相交流式又は直流式としてもよい。
C-1.全体
上記実施形態では、舵角比例FF制御、AP微分FF制御及びFB制御のそれぞれを行った(図2参照)。しかしながら、例えば、AP微分FF制御に着目すれば、舵角比例FF制御及びFB制御の一方又は両方を省略することも可能である。
上記実施形態では、舵角θst及び車輪速Vwに基づくマップをAP微分トルクTff2の算出(選択)に用いた(図4のS4、S5)。しかしながら、例えば、AP微分トルクTff2の利用に着目すれば、これに限らない。例えば、AP開度θapの変化速度VapとトルクTff2との関係を規定した単一のマップを設けておき、当該単一のマップを用いてトルクTff2を選択又は算出してもよい。
上記実施形態では、AP微分FF制御において、AP開度θapの変化速度Vapに応じて左右後輪36a、36bのトルク差ΔTを変化させた(図4のS5)。しかしながら、例えば、AP開度θapの変化速度Vapに応じて左右後輪36a、36bのトルクを変化させる観点からすれば、これに限らない。例えば、トルク差ΔTの調整に加えて又はこれに代えて、変化速度Vapに応じてFF合計トルクTff_total(例えば、トルクTff2)を増加又は減少させることも可能である。例えば、変化速度Vapが増加した場合、FF合計トルクTff_totalを増加させることができる。当該制御によっても、車両10の姿勢がより安定し又は運転者の意思(高速旋回)に対する応答性を高めることが可能となる。
