PROBLEM TO BE SOLVED: To provide a vehicle controller for achieving satisfactory steering feelings by suppressing the increase of vibration generated in a steering system. SOLUTION: A specific frequency extraction part 51 extracts frequency components corresponding to vibration promoting the generation of a rattle sound in a deceleration mechanism configuring an EPS actuator 22 from a pinion angleθp as a signal showing the state of a steering system, and outputs the effective value as a power spectrum Sp. Then, when the power spectrum Sp is a predetermined threshold or more, a speed ECU7 control a speed in order to reduce the power spectrum SP so that the speed V is out of a range from a first predetermined speed to a second predetermined speed.
