Vehicle controller

A vehicle controller that controls a power train of a vehicle, wherein

• the vehicle controller is configured to switch control of the power train between a first control and a second control, the second control reducing 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,
• the vehicle is a hybrid electric vehicle in which the power train includes an internal combustion engine and an electric motor,
• the first control and the second control are each control of a rotation speed of the electric motor, and
• the second control adjusts the rotation speed of the electric motor such that a rotation speed of the internal combustion engine becomes lower than in a case in which the first control controls the rotation speed of the electric motor.

• the vehicle is a hybrid electric vehicle in which the power train includes an internal combustion engine and an electric motor,
• the first control and the second control each switch between hybrid traveling and EV traveling in accordance with a traveling state of the vehicle, the hybrid traveling being a mode in which the vehicle travels with the internal combustion engine running, and the EV traveling being a mode in which the vehicle travels using driving force of the electric motor with the internal combustion engine being in a stopped state, and
• a range of the traveling state of the vehicle in which the EV traveling is performed is wider in the second control than in the first control.
