ABSTRACT:
A running control apparatus for an engine-driven vehicle includes a throttle command setting unit for setting a throttle command value based on an accelerator operation degree detected by an accelerator operation degree detector, and a throttle opening and closing driving unit controlled by a throttle opening and closing control unit for adjusting the opening of a throttle valve to the throttle command value, the throttle command value being set to change at a change rate smaller than a change rate of the accelerator operation degree in a region where the accelerator operation degree is small, while, to change at the change rate larger than the change rate of the accelerator operation degree in a region where the accelerator operation degree is large, and the running control apparatus further includes an A/T load signal setting unit and an automatic transmission control unit, in which the A/T load signal setting unit sets an A/T load signal so that the A/T load signal approximates to the throttle command value as the accelerator operation degree decreases, while, the A/T load signal approximates to the accelerator operation degree as the accelerator operation degree increases, and the automatic transmission control unit performs speed change control of an automatic transmission based on the A/T load signal and a vehicle speed signal detected by a vehicle speed detector.
