An automotive driving control system is described which consists of a stepless transmission provided between an engine and driving wheels, a transmission control means for controlling the transmission ratio of the stepless transmission, a throttle valve disposed in the intake passage of the engine, a throttle valve driving means for driving the throttle valve to control the opening degree thereof, first detecting means for detecting the amount of operation of the accelerator, second detecting means for detecting acceleration requirement. A control means is included which receives the outputs of the first and second detecting means to control the transmission control means and the throttle valve driving means to respectively control the transmission ratio of the stepless transmission and the opening degree of the throttle valve so that the engine output requirement as represented by the amount of operation of the accelerator is satisfied and control at least one of the transmission control means and the throttle valve driving means so that engine output corresponding to the amount of operation of the accelerator is obtained when the acceleration requirement is smaller than a predetermined value and maximum engine output is obtained when the acceleration requirement is larger than the predetermined value wherein acceleration requirement greater than the predetermined value corresponds to an abrupt acceleration of an automobile.
