PROBLEM TO BE SOLVED: To provide an electromagnetic valve driving device capable of suppressing heat generation during constant current control.SOLUTION: An electromagnetic valve driving unit 30 performs second constant current control, in which a constant current driver 23 is on-controlled when a current value of a detected coil current I reaches a lower limit threshold Icor below, and the constant current driver 23 is off-controlled when the current value of the coil current I reaches an upper limit threshold Icor above. A ripple setting unit 37 is provided for changing a second specified range S by changing the lower limit threshold Icand a ripple width value. |
