ABSTRACT:
There is provided wheel speed detection means for detecting a wheel speed V based on a pulse signal corresponding to a rotational speed of a wheel, driving torque integration means calculates an integral value TINdt of driving torque TINgenerated by the engine, and running situation determination means determines a vehicle running situation based on an actual wheel speed V and the integral value TINdt of the driving torque TIN. That is, the running situation determination means appropriately determines the vehicle running situation by comparing the actual wheel speed V which varies according to the vehicle running situation, and the function f (TINdt) even when the actual wheel speed is in the extremely low speed region. The function f (TINdt) is the function of the integral value TINdt of the driving torque TIN, and is also the function of the estimated wheel speed VPthat is estimated based on the integral value TINdt of the driving torque TIN.
