    Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of smoke by reducing the transient state of a load on an engine when a PM collecting device is in an easily clogged state. SOLUTION: When the accumulated amount of PM of the PM collecting device exceeds a specified amount (step S10) and the load on the diesel engine is in a transient state, the diesel engine is drivingly controlled by a series hybrid system (step S11 denial, step S12) until the regeneration control of the PM collecting device is performed so that the accumulated amount becomes a specified amount or below. Namely, the engine is driven so that the load becomes a load larger than a requested load for the running of the engine to regenerate an excess output thus produced by a motor generator and drive the motor generator to assist a torque short in acceleration. Thus, the engine can be operated substantially at a constant load, and the transient state of the load on the engine can be remarkably reduced. COPYRIGHT: (C)2005,JPO&NCIPI

    解决方案：当PM收集装置的PM的累积量超过规定量（步骤S10），柴油发动机的负荷处于过渡状态时，柴油发动机由串联混合动力系统驱动控制（步骤 S11否认，步骤S12），直到执行PM收集装置的再生控制，使得累积量变为规定量以下。 也就是说，发动机被驱动，使得负载变得大于用于发动机运行的要求负载的负载，以再生由电动发电机产生的过量输出并驱动电动发电机以辅助加速度短的转矩。 因此，发动机可以基本上以恒定的负载运转，并且可以显着地减少发动机上的负载的过渡状态。 版权所有（C）2005，JPO＆NCIPI

    Abstract: PROBLEM TO BE SOLVED: To suppress generation of noise when fastening a driving system caused by reversal of torque by preventing the reversal of the torque outputted to an input shaft of a transmission from an electric motor when an internal combustion engine is in an operation state generating vibration or booming noise. SOLUTION: When target engine speed Ne* and target torque Te* of an engine are present in booming noise area and when temporary torque Tm2tmp is within a prescribed area range including a value 0 by a threshold value Tref, a shift stage of the transmission is upshifted (S210), and torque instructions Tm1*, Tm2* of the motors MG1, MG2 are set such that request torque Td* is outputted to a driving shaft out of the prescribed area range of the temporary torque Tm2tmp though it is present in the booming noise area. Thereby, when the engine is operated in the booming noise area, the generation of the noise due to fastening which may be generated by reversing the torque of the motor MG2 can be suppressed.

    Abstract: PROBLEM TO BE SOLVED: To reduce acceleration shock in engine start during EV running.
    SOLUTION: If a running mode is in the EV running (YES in a step S10), and running information such as actual fuel injection amount Qfin, accelerator opening, and a vehicle speed is read (S20), a virtual engine speed NE0 is calculated (S30), a virtual fuel injection amount Qfin0 is calculated from a governor characteristic map based on the engine speed NE0 and the accelerator opening (S40). A target engine torque TEPn and actual engine torque TETn are calculated by using a torque conversion map, and differential torque ΔTEn is calculated (S50). When an engine start instruction is issued (YES in S60), differential torque ΔTE(n-1) calculated from torque TEP(n-1), TET(n-1) just before the start is held as the differential torque ΔTEn in the start (S70), and the differential torque is set as a torque assist amount Tmg (S80). When the engine start instruction is not issued (NO in S60), the present differential torque ΔTEn is set as the torque assist amount Tmg as it is (S90, S80).

    CPC classification number: Y02T10/7077

    Abstract: PROBLEM TO BE SOLVED: To efficiently charge a battery while suppressing the discharge of smoke in a diesel hybrid vehicle. SOLUTION: In case that the amount of battery charge SOC drops under a specified tolerance (positive in step S10), a stepped automatic transmission is shifted down from its stationary travelling at a maximum gear change stage to a low-speed stage which is lower by one stage (S11), and then even in case that it enters a shift up region to a maximum gear change stage by reacceleration, the shift up to the maximum gear change stage is inhibited (positive in step S12 and step S13), and the high-rotation operation of a diesel engine is executed to activate a motor-generator as a generator thereby charging the battery. When the battery is charged and the amount of charge SOC reaches a specified tolerance or over (negative in step S10), the speed is changed according to a usual schedule (step S14).
