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, an operating state detector for detecting a particular operating state of the engine such as 'knock' or resonance with the vehicle body, and a controller for controlling the transmission controller and the throttle valve driver. The controller controls the transmission controller and the throttle valve driver to respectively control the transmission ratio of the stepless transmission and the opening degree of the throttle valve so as to obtain that engine output which corresponds to the amount of depression of the acceleration pedal. When the particular operating state of the engine occurs, the controller controls the transmission controller and the throttle valve driver to respectively control the transmission ratio and the opening degree of the throttle valve so that the engine speed is changed without changing the engine output corresponding to the amount of depression of the accelerator pedal.
