    • A regenerative switched reluctance motor and a motor drive system therefor are provided. The motor has a rotor 33 with stacked rotor units 33a-33d each comprising 2n salient poles and a stator 31 with stacked stator units 31a-31d surrounded by and corresponding to the rotor units and each comprising 4n magnetic poles to form a predetermined gap with the salient poles of the corresponding rotor unit. A first excitation coil 32(A) is wound on every other one of the 4n magnetic poles of each stator unit, while a second excitation coil 32(B) is wound on the remaining magnetic poles thereof. The rotor units are sequentially shifted by a predetermined angle in angular position relative to the stator units. The switched reluctance motor and the motor drive system can efficiently drive the motor and recover regenerative power with little torque ripple and noise.

    • A high-pressure pump section pumps fuel in a fuel tank into a delivery pipe. An injector injects the fuel in the delivery pipe directly into a combustion chamber of an engine. An ECU calculates fuel injection quantity based on an operation state of the engine and calculates fuel injection time based on the fuel injection quantity and pressure of the fuel in the delivery pipe. The ECU calculates fuel injection start timing based on the operation state of the engine. The ECU sets the fuel injection time and the fuel injection start timing as a base injection period. When a fuel inflow period, in which the high-pressure fuel flows into the delivery pipe with the fuel pumping by the high-pressure pump section, overlaps with the base injection period, the ECU changes the base injection period to eliminate or reduce the overlap.
    • 高压泵部分将燃料箱中的燃料泵送到输送管中。 喷射器将输送管中的燃料直接喷射到发动机的燃烧室中。 ECU根据发动机的运转状态来计算燃料喷射量,并基于输送管内的燃料的燃料喷射量和压力计算燃料喷射时间。 ECU根据发动机的运转状态来计算燃料喷射开始时刻。 ECU将燃料喷射时间和燃料喷射开始定时设定为基准喷射期间。 当燃料流入时段(其中高压燃料流入高压泵部分的燃料的输送管道)与基础喷射期间重叠时,ECU改变基准喷射周期以消除或减少重叠 。

    • From among high upland area determination data stored in a hard disk drive, only a portion corresponding to a required segmental region is read into an external memory along with traveling of a vehicle. Determining of a high upland area is then executed based on the portion of the high upland determination in the external storage device. When a high-upland division is present in a vicinity of a present position, a portion of the high upland area determination data is read into the external memory. The read portion of the high upland area determination data corresponds to a high upland area, which covers all the high-upland divisions adjacently existing starting from the high-upland division in the vicinity of the present position. When a high-upland division is not present in the vicinity of the present position, a portion of the high upland area determination data corresponding to a segmental region having a predetermined minimum range centering on the present position is read into the external memory.
    • 从存储在硬盘驱动器中的高地区确定数据中,只有与所需分段区域对应的部分与车辆的行驶一起被读取到外部存储器中。 然后根据外部存储装置中的高地区确定部分来执行高地区的确定。 当在当前位置附近存在高地分区时,将高地区确定数据的一部分读入外部存储器。 高地区确定数据的读取部分对应于高地区,覆盖从现在位置附近的高地分区开始的所有高地陆地分区。 当在当前位置附近不存在高地区划分时,将与当前位置相对应的具有预定最小范围的段区域的高地盘区域确定数据的一部分读入外部存储器。
