A vehicle controller controls a power train of a vehicle and is configured to switch control of the power train between first control and second control. The second control reduces operating noise of the power train by a greater degree than the first control. The vehicle controller is configured to based on sounds in a passenger compartment, perform mood determination in order to determine whether an occupant of the vehicle is in a state of high tolerance for the operating noise or in a state of low tolerance for the operating noise; control the power train through the first control when determining that the occupant is in the state of high tolerance through the mood determination; and control the power train through the second control when determining that the occupant is in the state of low tolerance through the mood determination.
