Driving force distribution control apparatus of vehicle

A driving force distribution control apparatus, comprising:

• a front/rear driving force distribution controller for controlling a driving force distribution between a front wheel side and a rear wheel side;
• and
• a right/left driving force distribution controller for controlling a driving force distribution between a left wheel and a right wheel of at least one of the front wheel side and the rear wheel side,
• when a predetermined steering drive condition on a high μ road is satisfied, a control amount by the front/rear driving force distribution controller is decreased in response to at least an accelerating condition, when a predetermined steering drive condition on a low μ road is satisfied, a control amount set by the right/left driving force distribution controller is decreased in response to at least the accelerating condition, and
• when a vehicle speed is a high speed larger than a preset speed value and an absolute value of lateral acceleration actually generated in the vehicle is smaller than a preset value, the front/rear driving force distribution controller corrects the control amount to become a small control amount.

• when a vehicle speed is determined to be a very low speed smaller than a preset speed value, the right/left driving force distribution controller corrects the control amount to become a small control amount.
