Vehicle running control appartus and vehicle running control method

The vehicle running control apparatus according to claim 11, wherein the driving torque integration device calculates the integral value of the driving torque based on a value of output required of the driving force source.

The vehicle running control apparatus according to claim 11, wherein the running situation determination device determines the vehicle running situation based on an actual wheel speed and the integral value of the driving torque, according to a map stored in advance, which includes a border line for distinguishing between different vehicle running situations, and which uses the wheel speed and the integral value of the driving torque as parameters.

The vehicle running control apparatus according to claim 11, wherein the running situation determination device determines the vehicle running situation when the integral value of the driving torque has reached a predetermined value.

The vehicle running control apparatus according to claim 11, further comprising:

• a frictional engagement device that controls a distribution ratio at which the driving torque is distributed to a front wheel and a rear wheel among plural wheels;
• and
• an engagement force control device that controls engagement force of the frictional engagement device according to a result of a determination on the vehicle running situation that is made by the running situation determination device.
