之后CPU72将发动机速度需求值Nereq与发动机速度下限Nemin之间的较大值设定为发动机22的目标转速Ne,(步骤S160 ),并用目标转速Ne伞除发动机动力需求值Pe,以计算发动机22的目标扭矩Te丰(步骤S170)。 After the CPU72 between the larger lower limit engine speed Nemin Nereq engine speed demand value set to the target rotation speed Ne of the engine 22 (step S160), and the umbrella with the target rotation speed Ne of the engine power demand except Pe, the engine 22 to calculate The target torque Te Feng (step S170). 将发动机速度需求值Nereq与发动机速度下限Nemin之间的较大值设定为发动机22的目标转速Ne,的目的在于确保对于发动机动力需求值Pe,中的突然增加的快速响应。 The larger value between the lower engine speed Nemin Nereq demand value and the engine speed of the engine 22 is set as the target rotation speed Ne, the purpose is to ensure that the engine power demand Pe, the sudden increase of rapid response. 在一个示例中,在混合动力车辆20在较高速度下行驶时,驾驶员可在伴随驱动动力需求值Pv+中的一些减小(但没有减小到零) 的减速状态下自在加速器踏板83上。 In one example, when the hybrid vehicle 20 traveling at a higher speed, the driver can be associated with the drive power demand Pv + some of the accelerator pedal 83 itself is reduced on the lower (but not reduced to zero) the deceleration state . 在这种情况下,发动机速度需求值Nereq低于发动机速度下限Nemin。 In this case, the engine speed is lower than the required value Nereq engine speed low Nemin. 通常,与仅通过转速上升而增加发动机动力相比,可在更短的时间周期内实现仅通过扭矩上升而增加发动机动力。 Typically, compared to the speed rises only by increasing engine power and, in a shorter period of time to achieve the torque increased only by increasing engine power. 这是由于增加吸入空气流量和燃料喷射量所需的时间比增加发动机22的转动系统的转速所需的时间少。 This is less time due to the increased time required for suction air flow and the fuel injection quantity ratio increases the rotation speed of the engine system 22 required. 也就是说,在高于发动机速度需求值Nereq 的发动机速度下限Nemin下驱动的发动机,对于从发动机22中输出动力增加的要求具有更快/更高的响应性。 That is, the engine speed is higher than the required value of engine speed limit Nemin Nereq the driving engine, the power output from the engine 22 is required to have increased faster / higher responsiveness.

之后CPU72根据下面给出的公式(1)从发动机22的目标转速Ne、齿圏轴32a的转速Nr ( -Nm2/Gr)、以及动力分配集成机构30的传动比p计算电机MGl的目标转速Nml、同时根据下面给出的公式(2)从所计算的目标转速NmP和电机MGl的当前转速Nml计算电机MGl的扭矩指令Tml* (步骤S210):<formula>formula see original document page 16</formula> After the CPU72 according to the formula given below (1) of the engine 22 from the target speed Ne, the rings of teeth 32a of the shaft rotation speed Nr (-Nm2 / Gr), and the power distribution integration mechanism 30 of the transmission ratio p calculated target rotation speed Nml of the motor MGl while (2) calculating the motor MGl torque command from the current speed Nml calculated target speed NmP and motor MGl according to the formula given below Tml * (step S210): <formula> formula see original document page 16 </ formula >

的特定驱动点下当从处于稳定运行中的发动机22中输出扭矩Te+时传输到齿圏轴32a的扭矩、以及当从电机MG2中输出扭矩Tm2孝时通过减速器35施加于齿圏轴32a的扭矩。 Juan torque gear shaft 32a, and when the output from the motor MG2 torque Tm2 filial reducer 35 is applied to the teeth by Juan shaft 32a under specific driving point when Te transfers to + 22 output from the engine is running and stable torque torque. 公式(2 )是用于在目标转速NmP下驱动并转动电机MG1的反馈控制的关系式。 Equation (2) is used to drive and rotate the motor MG1 relational expression of feedback control at the target rotational speed NmP. 在以上给出的公式(2)中,右侧第二项中的"kl"和第三项中的"k2"分别表示比例增益和积分项的增益。 In the formula given above (2), the second term on the right side "kl" and the third "k2" represent proportional and integral gain entry.

在电机MG1的目标转速NmP和扭矩指令TmP的计算之后,CPU72根据下面给出的公式(3)和(4)作为从电机MG2中输出的最小扭矩和最大扭矩计算扭矩下限<formula>formula see original document page 16</formula>通过用电机MG2的输入的当前转速Nm2分别除蓄电池50的输入极限Win与作为扭矩指令TmP和输入的当前转速Nml的乘积的电机MG1的功耗(电力消耗,发电)之间的差、蓄电池50的输出极限Wout与电机MGl 的功耗(发电)之间的差,分别给出扭矩下限Tmin和扭矩上限Tmax。 After the rotational speed and torque command TmP NmP calculation target the motor MG1, CPU72 (3) and (4) as the minimum torque and maximum torque output from the motor MG2 torque limit is calculated according to the formula given below <formula> formula see original document page 16 </ formula> motor MG2 by the input current rotation speed Nm2 are in addition to 50 of the input limit Win and as the current product and the input torque command TmP Nml speed of the motor MG1 battery power consumption (power consumption, power generation) the difference between the output limit Wout difference in battery power consumption of the motor MGl 50 (power generation) between the lower limit Tmin are given torque and torque upper limit Tmax. 之后CPU72根据下面给出的公式(5)从要求扭矩值T"、电机MG1的扭矩指令Tml、动力分配集成机构30的传动比p、以及减速器35的传动比Gr中计算将从电机MG2中输出的暂行电机扭矩Tm2tmp (步骤S230 ):Tm2tmp = ( Tr* + Tml* ) /p) /Gr (5 ) After the CPU72 (5) from the required torque value T ", the motor MG1 torque command Tml, the drive power distribution integration mechanism 30 than p, and the reduction gear 35 will drive the motor MG2 are calculated according to the equation given below in the ratio of Gr Interim motor output torque Tm2tmp (step S230): Tm2tmp = (Tr * + Tml *) / p) / Gr (5)

CPU72将暂行电机扭矩Tm2tmp限制于所计算的扭矩下限Tmin和扭矩上限Tmax之间的范围以设定电机MG2的扭矩指令Tm2w (步骤S240)。 CPU72 the provisional limit motor torque Tm2tmp calculated in the torque limit Tmin and torque range between the upper limit Tmax to set the motor MG2 torque command Tm2w (step S240). 以这种方式设定电机MG2的扭矩指令Tm2+将输出到齿團轴32a或驱动轴的要求扭矩值T"限制在蓄电池50的输入极限Win与输出极限Wout之间。可容易地从图7的列线图引出公式(5)。 In this way set the motor MG2 torque command Tm2 + output to the gear shaft 32a or the drive shaft group required torque value T "is limited to between the battery input limit Win and the output limit of 50 Wout. Can be easily from Fig. 7 nomograms leads equation (5).

在从驱动控制例程中退出之前,CPU72将发动机22的目标转速Ne+和目标扭矩Tew输送到发动机ECU24,同时将电机MG1和MG2的扭矩指令TmP和Tm2+输送到电机ECU40 (步骤S250 )。 Before exiting from the drive control routine, CPU72 the target engine speed Ne + 22 and the target torque Tew delivered to the engine ECU24, while the motor MG1 and MG2 torque command Tm2 + TmP and delivery to the motor ECU40 (step S250). 发动机ECU24接收目标转速Ne+和目标扭矩Te力并执行发动机22的燃料喷射控制和点火控制,以在目标转速Ne力和目标扭矩Te力的指定驱动点下驱动发动机22。 Engine ECU24 receives the target rotation speed Ne + and the target torque Te of the engine power and performs fuel injection control and ignition control 22 to drive the engine 22 at a specified drive point of the target rotation speed Ne and the target torque Te force force. 电机ECU40接收目标指令TmP和Tm2w并执行包含在各个逆变器41和42中的开关元件的开关控制,以用扭矩指令TmP驱动电机MG1以及用扭矩指令Tm2^'驱动电机MG2。 Motor ECU40 TmP target instruction and receiving and executing Tm2w contained in the respective inverters 41 and 42 in the switching control of the switching element, to use the torque command TmP drive motor MG1 with the torque command and Tm2 ^ 'drive motor MG2.

当在步骤8120确定驱动动力需求值卩„*等于0时,CPU72指定没有从发动机22中输出动力的要求并给出切断对于发动机22的燃料供应的指令(步骤S180)。 When the drive power demand is determined 8120 Jie „ * is equal to 0 at step, CPU72 specifies no power output from the engine 22 and gives the requirements for the fuel supply cut engine 22 instruction (step S180). 依照一具体程序,混合电子控制单元70通过通信端口向发动机ECU24发出燃料切断控制信号。 In accordance with a specific procedure, hybrid electronic control unit 70 to issue a fuel cut control signal to the engine through the communication port ECU24. 之后CPU72将如上所述的从发动机速度下限设定图中读出的与车速V相对应的发动机速度下限Nemin设定为发动机22的目标转速Ne力(步骤S1卯),并将发动机22的扭矩指令Te^殳定得等于0。 After the CPU72 as described above from the engine speed limit setting map is read out with the vehicle speed V corresponding to the engine speed limit Nemin is set to force the target rotation speed Ne (step S1 d) of the engine 22, the engine 22 and the torque Shu Te ^ instruction set to be equal to zero. 之后,在从驱动控制例程中退出之前,CPU72执行步骤S210到S240的处理以设定电机MGl和MG2的扭矩指令TmP和Tm2w并将所述设定输送到发动机ECU24和电机ECU40 (步骤S250 )。 Then, before exiting from the drive control routine, CPU72 process steps S210 to S240 to set the motor MGl and MG2 torque command TmP and Tm2w and the set delivered to the engine and the motor ECU24 ECU40 (step S250) . 当车速V低于参考车速Vref 时,将发动机速度下限Nemin设定得等于O。 When the vehicle speed V is lower than the reference speed Vref, the engine speed limit is set to be equal to O. Nemin 因此在没有转动的情况下停止发动机22。 So stop the engine in the absence of rotation 22.

在混合动力车辆20在较高速度下行驶时,驾驶员可以在不加速(不踏油门)状态踩踏在加速器踏板83上。 When the hybrid vehicle 20 traveling at high speed, the driver can not accelerate (not step throttle) state stepping on the accelerator pedal 83. 在不加速状态下,驱动动力需求值Pvw 等于O。 Without accelerated state, the drive power demand Pvw equal to O. 因此发动机22被切断燃料并在发动机速度下限Nemin下转动。 Therefore, the engine 22 is cut off the fuel and the engine rotational speed limit Nemin under. 在这200580012291.5 In this 200,580,012,291.5

种情况下驾驶员員加速器踏板83取消了燃料切断并立刻恢复吸入空气流量和燃料喷射以从发动机22中输出扭矩。 Case under the driver's accelerator pedal 83 members canceled the fuel cut-off and immediately resume the intake air flow rate and the fuel injection to the engine 22 from the torque output. 发动机22在发动机速度下限Nemin下转动,这使得发动机22有效地输出使得混合动力牟辆20在当前车速V下恒速驾驶所需的动力。 Engine 22 in the engine speed low Nemin lower turning, which makes the output of the engine 22 effectively makes the hybrid vehicle 20 of the constant-speed power drive Mou required under the current vehicle speed V. 吸入空气流量和燃料喷射量的简单调节能够使得发动机22立刻有效地输出使得混合动力车辆20恒速驾驶所需的动力。 Simple adjustment of the intake air flow rate and the fuel injection amount so that the engine 22 can be immediately effective output power of the hybrid vehicle 20 such that the desired constant speed driving. 发动机22的驱动点沿动作线(见图5)改变,所述动作线表示从能够使得发动机22有效地输出恒速驾驶所需的动力的特定驱动点开始的有M动机驱动点的延续。 Engine drive points along the operation line 22 (see FIG. 5) change, the line represents the operation of the engine 22 effectively enables the output power required for constant-speed driving of the driving point has a specific motor driver M continuation point. 与在低转速下驱动发动机22或停止发动机22的常规控制相比较,这种控制确保发动机22对于输出要求动力的更快速反应。 And at low speeds or stop the engine driving the engine 22 as compared to conventional control 22, which controls the engine 22 to ensure that the requirements for output power of more rapid response. 在本实施例的混合动力车辆20的结构中,如通过在步骤S230中设定暂行电机扭矩Tm2tmp清楚示出的,由来自于蓄电池50的电力供应驱动的电机MG2的输出扭矩补偿发动机22的延迟反应。 In the structure of the hybrid vehicle 20 of the present embodiment, such as by setting provisional motor torque Tm2tmp at step S230 shown clearly by the power supply from the battery 50 to drive the motor MG2 output torque of the engine to compensate for the delay 22 reaction. 要求动力从发动机22中的快速输出减少了蓄电池50的放电电力并有利地减少了蓄电池50的负荷。 Discharge power demand reduces the power of the battery 50 is output from the engine 22 rapidly and advantageously reduces the load on the battery 50. 因此这种布置有效地避免了较大电力的重复充电和放电所加速的蓄电池50的提前损坏。 This arrangement effectively avoids repeating the charge and discharge of large power accelerated damage to the battery 50 in advance.

如上所述的,本实施例的混合动力车辆20在不低于与车速V相对应的发动机速度下限Nemin的转动速度下驱动发动机22,从而提高发动机22对于输出动力需求值的改变的响应性。 As described above, the present embodiment is a hybrid vehicle 20 in the vehicle speed V is not lower than the speed corresponding to the engine rotational speed limit Nemin drive engine 22, thereby increasing the output power of the engine 22 to change the value of the demand response. 本实施例的控制有利地减少了由于发动机的延迟响应所导致的所需驱动动力的不足,从而降低所需的蓄电池50 的放电量并减少蓄电池50的负荷。 Control example of the present embodiment advantageously reduces the required driving force deficiency due to delays caused by the response of the engine, thereby reducing the discharge amount of the battery 50 and the required reduction of the battery load 50. 降低的充电和放电量有利地避免了较大电力量的重复充电和放电所加速的蓄电池50的提前损坏。 Reduce the amount of charging and discharging advantageously avoids large electric power repeated charging and discharging of the battery early damage accelerated 50. 发动机22的更快速响应性还确保了发动机22的驱动点沿动作线到有效发动机驱动点的即时移位。 Faster response engine 22 also ensures that the engine driving points along the line 22 to the effective operation of the engine-driven point shifted in time. 在驱动动力需求值Pw等于0时而不需要从发动机22中输出动力的情况下,本实施例的控制程序停止对于发动机22的燃料喷射,因此有利地提高了燃料消耗。 In the drive power demand is equal to 0 Pw sometimes do not need power from the output 22 of the engine, the control program according to the present embodiment stops the fuel injection of the engine 22, thus advantageously improving the fuel consumption.
