Abstract
A vehicle includes an engine including a forced induction device, a knock sensor and a crank angle sensor that detect an occurrence of LSPI, a battery that supplies electric power to a second motor generator, and an ECU. When an occurrence of the LSPI is detected, the ECU restricts a maximum torque, which can be output by the engine with the forced induction device, more than when an occurrence of the LSPI is not detected to prevent an engine operating point from being included in an LSPI area, and when an output of the engine becomes insufficient along with the restriction on the maximum torque, the engine compensates for an amount of the insufficient output with electric power supplied from the battery.
