ABSTRACT:
An automatic transmission system for a vehicle in which the gear change operations are carried out in response to a condition signal relating to the speed of an internal combustion engine, which is determined by detecting the operating speed of a brake pedal of the vehicle and a variable filter circuit for receiving the condition signal and for removing any high frequency component of the condition signal, the frequency response characteristics of the variable filter circuit being changeable in response to the operating speed of a brake pedal means. The system is controlled in response to an output signal derived from the variable filter circuit so as to shift the transmission into a gear position determined on the basis of a predetermined map data in response to the operating condition of the vehicle at each instant, whereby the gear change operation can be carried out so as to match the actual operating condition of the vehicle.
