    • PROBLEM TO BE SOLVED: To provide an electric driving controller which can prevent application of overvoltage to an electronic apparatus connected to the output of an electric power source. SOLUTION: The electric driving controller is used for a vehicle which includes an AC motor 1 for traveling, a power converter 2 for driving the AC motor 1, an electric power source 4 for supplying electric power to the power converter 2, and a smoothing means 5 for smoothing the output of the electric power source 4. The electric driving controller includes a DC voltage detecting means 51 for detecting DC voltage V dc applied to the smoothing means 5. When the DC voltage V dc detected by the DC voltage detecting means 51 becomes a predetermined voltage or above, a motor control section 11 corrects the input characteristics of the power converter 2 to such ones as to reduce the DC voltage V dc . Consequently, application of overvoltage to an electronic apparatus connected to the output of the electric power source can be prevented. COPYRIGHT: (C)2010,JPO&INPIT
