Patent ID: 7749130

Claim:
A vehicle, comprising: an internal combustion engine; an electric power-mechanical power input output structure that is connected to an output shaft of the internal combustion engine and to a power shaft, which is rotatable independently of the output shaft, and inputs and outputs driving force from and to the output shaft and the power shaft with rotation based on a rotation speed of the output shaft and a rotation speed of the power shaft and input and output of electric powers and mechanical powers; an accumulator that transmits electric power to and from the electric power-mechanical power input output structure; a transmission that is constructed to connect the power shaft with a driveshaft linked to drive wheels for transmission of power between the power shaft and the driveshaft with a change of speed and to disconnect the power shaft from the driveshaft; a vehicle speed measurement unit that measures a vehicle speed; a gearshift position detection unit that detects a setting of gearshift position; a target state setting module that sets a target state of the transmission based on the detected setting of gearshift position; and a control module that controls the transmission to connect the power shaft with the driveshaft and attain an actual gear change of the transmission to the target state in response to a change of the gearshift position from a neutral position to a driving position when the measured vehicle speed is within a predetermined vehicle speed range, while controlling the transmission to prohibit the connection of the power shaft with the driveshaft and the actual gear change of the transmission to the target state regardless of the change of the gearshift position from the neutral position to the driving position when the measured vehicle speed is out of the predetermined vehicle speed range.
