Abstract
A gear-shifting shock suppressing system for a vehicle provided with an automatic transmission which shifted to a desired gear-speed on the basis of a gear-shifting signal controls the output of the engine of the vehicle in order to suppress gear-shifting shock which occurs when the automatic transmission shifts. The gear-shifting shock suppressing system detects the interval between successive two gear-shifting signals and controls the output of the engine when the interval between successive two gear-shifting signals is longer than the predetermined time in a manner different from the manner in which the gear-shifting shock suppressing system controls the output of the engine when the interval between successive two gear-shifting signals is shorter than the predetermined time.
