Abstract
A vehicle controller is applied to a vehicle having an engine, a transmission, a clutch connecting and disconnecting a crankshaft of the engine and an input shaft of the transmission to each other, a vehicle wheel connected to a drive axle of the transmission, and an electric motor disposed to be capable of transmitting torque to the crankshaft The vehicle controller controls driving of the electric motor such that a rotation speed of the engine is reduced when an operation state of the engine shifts from operation to stop. The vehicle controller controls rotation of the crankshaft so as to avoid coincidence between a crank angle and a top dead center angle of the engine in a vibration amplification region amplifying an amplitude of vibration generated when the operation state of the engine shifts to the stop.
