Abstract
A vehicle running control apparatus for a motor vehicle is provided which is able to accomplish a braking operation that meets with the driver's intention when the vehicle is decelerated under running control, while assuring improved safety. During deceleration control, target deceleration calculating device calculates a target deceleration degree .alpha.a of the subject vehicle in accordance with a deceleration degree of the preceding vehicle (S30). When the target deceleration degree .alpha.a is smaller than a predetermined deceleration degree X1, braking control device controls an operation of an actuator so as to drive a brake system to generate braking force that corresponds to the target deceleration degree .alpha.a (S32, S36). When the target deceleration degree .alpha.a is equal to or greater than the predetermined deceleration degree X1, on the other hand, the actuator is operated so as to drive the brake system to generate auxiliary braking force that corresponds to the predetermined deceleration degree X1 (S32, S34, S36).
