Abstract
A gear shifting system for an automotive vehicle equipped with an internal combustion engine comprises a load sensor for sensing the shift load generated by a shifting motion of a driver or a rider, a power adjusting system for adjusting the engine power of the internal combustion engine, and a control unit for controlling the power adjusting system. The control unit is actuated in response to a signal from the load sensor when the sensed load is equal to or greater than a predetermined value, and outputs a control signal to the power adjusting system so as to adjust the engine power. The load sensor is assembled on a linkage system connected between a shift shaft of the power transmission and the shift pedal, so that the load sensor can detect a stretching load or a depressing load caused by shifting operation in the shift-up or shift-down mode, and for differentiating between them.
