AUTOMOTIVE DRIVING CONTROL SYSTEM

摘要

An automotive driving control system comprises a stepless transmission (14) provided between the engine (1) and the driving wheels (17), a transmission controlling means (18) for controlling the transmission ratio of the stepless transmission (14), a throttle valve driving means (36) for driving the throttle valve (3) of the engine (1), and a control means (38) for controlling the transmission control means (18) and the throttle valve driving means (3). The control means (38) controls the transmission control means (18) and the throttle valve driving means (36) according to the amount of depression of the accelerator pedal (30, and when the amount of depression of the accelerator pedal (30), is within a predetermined range, the control means (38) controls the throttle valve driving means (36) so that the opening degree of the throttle valve (3) is fixed at a predetermined value irrespective of the depressed amount of the accelerator pedal (30), and the transmission control means (18) to control the transmission ratio of the transmission (14) so that an engine output corresponding to the amount of depression of the accelerator pedal (30) can be obtained taking into account the predetermined value of the opening degree of the throttle valve (3).
