Abstract:
1. A vehicle, comprising: an internal combustion engine; an electric power-mechanical power input output assembly, having a generator constructed to input and output power, linked to an axle of the vehicle and connected with an output shaft of the internal combustion engine in such a manner as to be rotatable independently of the axle, and configured to input and output power to and from the axle and the output shaft through input and output of electric power and mechanical power; a motor constructed to input and output power to and from the axle of the vehicle or a different axle of the vehicle from the axle and to generate a counter electromotive force by rotation; a first inverter circuit for driving the generator; a second inverter circuit for driving the motor; an accumulator configured to supply and receive electric power to and from the generator and the motor via the first inverter circuit and the second inverter circuit; a short circuit abnormality detection module that detects a short circuit abnormality that at least one short circuit is formed in a part of phases of the second inverter circuit; a driving force demand setting module that sets a driving force demand required for driving the vehicle; and a controller configured to, when the short circuit abnormality is detected by the short circuit abnormality detection module, control the second inverter circuit so that switching elements of the second inverter circuit are stopped in a preset switching state while controlling the internal combustion engine and the first inverter circuit so that the vehicle is driven with an execution driving force that is a driving force based on a sum of the set driving force demand and a cancellation driving force for canceling at least a part of a braking force applied to the vehicle from the counter electromotive force generated by rotation of the motor.
