    • An electric power steering apparatus drives a motor to generate a steering assist force according to a steering torque and includes an output circuit for supplying the motor with electric power from at least one of a battery and an auxiliary power supply. The electric power steering apparatus has a control circuit which at or after detection of a breakdown of the battery, determines a length of time to the end of steering assist (decreasing time t1) based on the amount of energy stored in the auxiliary power supplies and which takes the determined length of time to perform output decreasing control to gradually decrease the upper limit of power supplied for the steering assist to practically zero according to a constant gradient. Thus is provided an electric power steering apparatus which is adapted to prevent a sudden fall of the steering assist force in the event of a battery breakdown while effectively utilizing the available stored energy.
    • 电动助力转向装置驱动电动机以根据转向转矩产生转向辅助力,并且包括用于向电动机提供来自电池和辅助电源中的至少一个的电力的输出电路。 电动助力转向装置具有控制电路,其在检测到电池故障之后或之后,基于存储在辅助电源中的能量的量来确定转向辅助结束时的时间长度(减小时间t1);以及 其采用所确定的时间长度来执行输出减小控制,以根据恒定梯度逐渐减小为转向辅助提供的功率的上限,几乎为零。 因此,提供了一种电动助力转向装置,其适于在有效利用可用的储存能量的同时防止在电池击穿的情况下转向辅助力的突然下降。

    • An engine lubrication system for a multi-cylinder engine, comprising: plurality of crank chambers that are partitioned by crankshaft bearing portions of the engine; pumps that take out oil from a lower portion of the engine; oil collection passages that are respectively provided for the crank chambers, a designated number of the oil collection passages being merged and connected to at least one of suction ports of the pumps; an oil storage section that temporarily stores the oil taken out from the lower portion of the engine; a lubrication part that supplies the oil in the oil storage section to a portion to be lubricated of the engine; and a pressure variation suppression section that is provided between the suction ports of the pumps and the designated number of the crank chambers to be merged, the pressure variation suppression section suppressing pressure variations in the crank chambers.
    • 一种用于多缸发动机的发动机润滑系统,包括:由发动机的曲轴轴承部分分隔的多个曲柄室; 从发动机下部取出油的泵; 分别设置用于曲轴室的油收集通道,指定数量的采油通道合并并连接到泵的吸入口中的至少一个; 储油部,暂时存储从发动机的下部取出的油; 润滑部,其将储油部中的油供给到所述发动机的被润滑部; 以及压力变化抑制部,其设置在所述泵的吸入口与要合并的所述指定数量的所述曲柄室之间,所述压力变化抑制部抑制所述曲柄室的压力变化。
