Abstract
An automotive driving control system comprises a stepless transmission provided between the engine and the driving wheels, a transmission controller for controlling the transmission ratio of the stepless transmission, a throttle valve driver for driving the throttle valve of the engine, and a controller for controlling the transmission controller and the throttle valve driver. The controller controls the transmission controller and the throttle valve driver according to the amount of depression of the accelerator pedal. When the amount of depression of the accelerator pedal is within a predetermined range, the controller controls the throttle valve driver so that the opening degree of the throttle valve is fixed at a predetermined value irrespective of the amount of depression of the accelerator pedal, and controls the transmission controller to control the transmission ratio of the transmission so that an engine output corresponding to the amount of depression of the accelerator pedal can be obtained taking into account the predetermined value of the opening degree of the throttle valve.
