Abstract
A vehicle includes an engine, a motor, a battery that stores an electric power for driving the motor, and a control apparatus. The control apparatus is configured to control the engine and the motor in one of control modes, the control mode includes a charge sustaining (CS) mode and a charge depleting (CD) mode. During the CS mode, a first determination is made to determine that the engine malfunction has occurred when a number of times of abnormal combustion occurring during a current trip is equal to or larger than a threshold. During the CD mode, instead of or in addition to the first determination, a second determination is made to determine that the engine malfunction has occurred when a cumulative number of times of abnormal combustion is equal to or larger than the threshold.
