电磁阀的控制装置以及控制方法
摘要：
在将用于线性电磁阀的螺线管的电流反馈控制的指令电流Ir设定在上限电流Irmax的范围内时，响应于向螺线管供电的电池的电压降低，将上限电流Irmax从第一上限电流Irmax1变更为小于第一上限电流Irmax1的第二上限电流Irmax2(S120)。即，在未产生电池的电压降低时，将指令电流Ir设定在第一上限电流Irmax1的范围内，在产生电池的电压降低时，将指令电流Ir设定在小于第一上限电流Irmax1的第二上限电流Irmax2的范围内(S110～S130)。由此，响应于电池的电压降低，将指令电流Ir限制在更小的上限电流Irmax的范围内，抑制螺线管的指令电流Ir和实际电流Ifb间的偏差变得过大。
摘要（英）：

When setting the command current Ir, which is used for current feedback control of the solenoid of a linear solenoid valve, to be less than an upper current limit Irmax, the upper current limit Irmax is changed from a first upper current limit Irmax1 to a second upper current limit Irmax2, which is smaller than the first upper current limit Irmax1, as the voltage of the battery supplying power to the solenoid decreases (S120). That is, when no decrease in battery voltage has occurred, the command current Ir is set to be less than a first upper current limit Irmax1 and when a decrease in battery voltage has occurred, the command current Ir is set to be less than a second upper current limit Irmax2, which is smaller than the first upper current limit Irmax1 (S110 - S130). The command current Ir is thereby limited to be less than a smaller upper current limit Irmax according to the decrease in battery voltage, keeping the deviation of the actual current Ifb from the solenoid command current Ir from becoming too large.
