A gear shifting control device for a transmission connected to an engine comprising: a pedal operation detection unit which detects a gear shifting operation of a shift pedal ; and a control unit which performs output suppression control for suppressing output of the engine in accordance with the gear shifting operation detected by the pedal operation detection unit , characterised in that the control unit includes: a change rate calculation unit which calculates a time change rate (DFSA) of a pedal load detection value (FS) detected by the pedal operation detection unit ; a load prediction unit which obtains a pedal load prediction value (FSC) after a specified time elapses from the time change rate (DFSA); a pedal load determination unit which determines whether or not the pedal load detection value (FS) reaches a first threshold value (FSCC); a predicted value determination unit which determines whether or not the pedal load prediction value (FSC) exceeds a second threshold value (FSCTC) when the pedal load detection value (FS) reaches the first threshold value (FSCC); and an output suppression control unit which performs the output suppression control when it is determined that the pedal load prediction value (FSC) exceeds the second threshold value (FSCTC). a pedal operation detection unit which detects a gear shifting operation of a shift pedal ; and a control unit which performs output suppression control for suppressing output of the engine in accordance with the gear shifting operation detected by the pedal operation detection unit , characterised in that the control unit includes: a change rate calculation unit which calculates a time change rate (DFSA) of a pedal load detection value (FS) detected by the pedal operation detection unit ; a load prediction unit which obtains a pedal load prediction value (FSC) after a specified time elapses from the time change rate (DFSA); a pedal load determination unit which determines whether or not the pedal load detection value (FS) reaches a first threshold value (FSCC); a predicted value determination unit which determines whether or not the pedal load prediction value (FSC) exceeds a second threshold value (FSCTC) when the pedal load detection value (FS) reaches the first threshold value (FSCC); and an output suppression control unit which performs the output suppression control when it is determined that the pedal load prediction value (FSC) exceeds the second threshold value (FSCTC). a change rate calculation unit which calculates a time change rate (DFSA) of a pedal load detection value (FS) detected by the pedal operation detection unit ; a load prediction unit which obtains a pedal load prediction value (FSC) after a specified time elapses from the time change rate (DFSA); a pedal load determination unit which determines whether or not the pedal load detection value (FS) reaches a first threshold value (FSCC); a predicted value determination unit which determines whether or not the pedal load prediction value (FSC) exceeds a second threshold value (FSCTC) when the pedal load detection value (FS) reaches the first threshold value (FSCC); and an output suppression control unit which performs the output suppression control when it is determined that the pedal load prediction value (FSC) exceeds the second threshold value (FSCTC). <EOS>
