A gearshift control system for a hybrid-drive electric vehicle, the vehicle comprising an engine having an output shaft, a transmission having an input shaft and an output shaft, the transmission changing and transmitting a rotation of the input shaft to wheels via the output shaft thereof, the transmission having gear positions including a neutral position and a vehicle-starting gear position, and selectively applying one of the gear positions according to a gear shift request, a clutch for connecting and disconnecting power transmission between the output shaft of the engine and the input shaft of the transmission, a rotating electric machine connected to the input shaft of the transmission for operating as an electric motor and an electric generator, a storage element for storing an electric power supplied from the rotating electric machine, the system comprising: determining means for determining whether or not the gear shifting request of the transmission exists; clutch disconnection means for disconnecting the clutch upon the gear shifting request of the transmission; neutral position setting means for changing over the gear position of the transmission to a neutral position when the clutch has been disconnected; mode selecting means for selectively operating the rotating electric machine in a motor mode and in a power generating mode so that a rotational speed of the input shaft of the transmission reaches a region of a synchronizing rotational speed depending on a requested gear position; and gear setting means for setting the gear position of the transmission from the neutral position to the requested gear position, characterized in that the determining means is configured to determine if a gear shifting request is a request to the vehicle-starting gear position, and if the request to the vehicle-starting position exists in a vehicle stationary state where the engine is running idle, the transmission is in the neutral position, and the clutch is connected; and when the request to the vehicle-starting position exists in the vehicle stationary state, the clutch disconnection means is configured to disconnect the clutch; the mode selecting means is configured to operate the rotating electric machine in the power generating mode to decrease the rotational speed of the input shaft until the rotational speed of the input shaft of the transmission reaches the region of the synchronizing rotational speed in the vicinity of a zero value after the clutch disconnection means disconnects the clutch; and the gear setting means is configured to set the gear position of the transmission from the neutral position to the vehicle-starting gear position when the rotational speed of the input shaft reaches the region of the synchronizing rotational speed in the vicinity of a zero value. determining means for determining whether or not the gear shifting request of the transmission exists;
