Abstract:
1. A vehicle driving force system used for a vehicle having a configuration in which a driving force output from a driving source is transmitted to wheels, comprising: wheel speed detection means for detecting the wheel speed of said vehicle; acceleration calculation means for calculating the acceleration of each wheel based upon the wheel speed detected by said wheel speed detection means; acceleration skid detection means having a function of determining whether or not a skid of the wheels has occurred based upon the comparison result between the acceleration of the wheels obtained by said acceleration detection means and a predetermined skid-detection acceleration threshold for detection of a skid of the wheels; and acceleration threshold adjustment means which selects as a basis for calculating said predetermined skid-detection acceleration threshold a smallest value from skid-detection acceleration thresholds derived from the throttle opening of the engine, the accelerator opening, the accelerator opening speed, the engine revolution, the driving force, the wheel speed, and the slope angle of the road.
