Abstract:
1. A power transmission control apparatus for a vehicle which includes an internal combustion engine (E/G) and an electric motor (M/G) as power sources, comprising: a manual transmission (M/T) which does not include a torque converter and includes: an input shaft (Ai) which receives power from the internal combustion engine, an output shaft (Ao) which receives power from the electric motor and which outputs power to a drive wheel of the vehicle, and a transmission mechanism (M) configured such that when a driver moves a shift operation member (SL) on a shift pattern to a hybrid-travel-stage shift completion position corresponding to a selected one of a plurality of gear stages (2-nd to 5-th gears) for hybrid travel in which the vehicle travels using both drive force of the internal combustion engine and drive force of the electric motor, the transmission mechanism establishes a power transmission route between the input shaft and the output shaft, the power transmission route having a transmission speed reduction ratio, which is the ratio of rotational speed of the input shaft to that of the output shaft, for the selected gear stage, and when the driver moves the shift operation member on the shift pattern to a motor-travel-stage shift completion position corresponding to a gear stage (EV gear) for motor travel in which the vehicle travels using only the drive force of the electric motor, the transmission mechanism establishes no power transmission route between the input shaft and the output shaft; and a friction clutch (C/T) which is interposed between the output shaft (Ae) of the internal combustion engine and the input shaft (Ai) of the manual transmission and whose engagement state changes in accordance with an operation quantity of a clutch operation member (CP) operated by the driver, wherein the transmission mechanism includes a movement restraining mechanism configured such that in a state in which the clutch operation member is not operated, the movement restraining mechanism prohibits movement of the shift operation member, on the shift pattern, to the motor-travel-stage shift completion position from a neutral position which differs from the motor-travel-stage shift completion position and in which no power transmission route is established between the input shaft and the output shaft, and in a state in which the clutch operation member is operated, the movement restraining mechanism permits movement of the shift operation member, on the shift pattern, from the neutral position to the motor-travel-stage shift completion position.
