Patent ID: 8359148

Claim:
A vehicle running control apparatus comprising: at least one of a driving torque generating device that applies a driving torque to a vehicle and a braking torque generating device that applies a braking torque to the vehicle; and a control device that calculates at least one of a target braking torque and a target driving torque such that a vehicle speed is controlled to become equal to a preset target vehicle speed, and controls the braking torque generating device or the driving torque generating device based on the calculated target braking torque or the calculated target driving torque; a running road determination portion that: sets weighted values of the driving torque and the braking torque in accordance with a running situation of the vehicle., sets a weighted driving torque by multiplying the driving torque by the weighted values of the driving torque, sets a weighted braking torque by multiplying the braking torque by the weighted values of the braking torque, and when the vehicle speed is controlled by the braking torque or the driving torque which the control device calculates, determines whether or not a road on which the vehicle is running is difficult to run on, on a basis of a sum of the weighted driving torque and the weighted braking torque.
