Abstract:
1. A vehicle, comprising: an internal combustion engine; an electric power-mechanical power input output assembly connected with a driveshaft linked to an axle of the vehicle and with an output shaft of the internal combustion engine in such a manner as to be rotatable independently of the driveshaft and configured to input and output power to and from the driveshaft and the output shaft through input and output of electric power and mechanical power; a motor capable of outputting power to the driveshaft; an accumulator configured to transmit electric power to and from the electric power-mechanical power input output assembly and the motor; an input output limits setting module that sets input and output limits of the accumulator as maximum allowable electric powers to be charged in and discharged from the accumulator, according to a state of the accumulator; an intermittent operation prohibition vehicle speed setting module that sets an intermittent operation prohibition vehicle speed for prohibiting an intermittent operation of the internal combustion engine, according to the set input limit of the accumulator; a vehicle speed detector that detects a vehicle speed; a driving power demand setting module that sets a driving power demand required for driving the vehicle; and a controller configured to, when the detected vehicle speed is less than the set intermittent operation prohibition vehicle speed, control the internal combustion engine, the electric power-mechanical power input output assembly, and the motor so that the vehicle is driven with a driving power corresponding to the set driving power demand in a range defined by the set input and output limits of the accumulator with the intermittent operation of the internal combustion engine, when the detected vehicle speed is more than or equal to the set intermittent operation prohibition vehicle speed, the controller controlling the internal combustion engine, the electric power-mechanical power input output assembly, and the motor so that the vehicle is driven with the driving power corresponding to the set driving power in the range defined by the set input and output limits of the accumulator with a continuous operation of the internal combustion engine, and a control mode setting module that sets at least one vehicle control mode of multiple vehicle control modes where output powers corresponding to driver's operation are different, wherein the intermittent operation prohibition vehicle speed setting module sets the intermittent operation prohibition vehicle speed, according to the set vehicle control mode, and the controller controls the internal combustion engine, the electric power-mechanical power input output assembly, and the motor, according to the set vehicle control mode.
