Abstract:
1. A shift control apparatus of a constant mesh transmission which is connected via a clutch to a power source mounted in a vehicle, the transmission shifting speeds by a gear corresponding to a desired speed being engaged when a shift selecting member is moved to a position corresponding to the desired speed, comprising: a drive torque detecting device that detects drive torque output from the power source; a transfer torque detecting device that detects transfer torque transferred from the clutch to the transmission; a load torque detecting device that detects load torque transferred from a driven wheel of the vehicle to the transmission; a switching device that switches the clutch from an engaged state to a released state when the shift is required while the vehicle is running; and a first shift controlling device that controls, in parallel with switching the clutch, the shift selecting member such that the engaged gear disengages when the load torque becomes greater than at least one of the drive torque and the transfer torque.
