Abstract
A driving force control apparatus of a motor vehicle including a first set of drive wheels and a second set of drive wheels, e.g., front wheels and rear wheels, which are driven with respective driving forces that are controlled independently of each other. The control apparatus calculates an actual slip rate difference between a slip rate of the first set of drive wheels and that of the second set of drive wheels, and controls distribution of driving force between the first set of wheels and the second set of wheels, based on the slip rate difference.
Claims24
A driving force control apparatus of a motor vehicle including a first set of drive wheels and a second set of drive wheels which are driven with respective driving forces that are controlled independently of each other, comprising:
- a slip rate difference calculating unit configured to calculate an actual slip rate difference between a slip rate of the first set of drive wheels and a slip rate of the second set of drive wheels;
- and
- a driving force distribution control unit configured to control distribution of driving force between the first set of wheels and the second set of wheels, based on the slip rate difference calculated by the slip rate difference calculating unit.
A driving force control method of a motor vehicle including a first set of drive wheels and a second set of drive wheels which are driven with respective driving forces that are controlled independently of each other, comprising the steps of:
- calculating an actual slip rate difference between a slip rate of the first set of drive wheels and a slip rate of the second set of drive wheels;
- controlling distribution of driving force between the first set of wheels and the second set of wheels, based on the calculated slip rate difference.
A driving force control apparatus of a motor vehicle including a first set of drive wheels and a second set of drive wheels which are driven with respective driving forces that are controlled independently of each other, comprising:
- slip rate difference calculating means for calculating an actual slip rate difference between a slip rate of the first set of drive wheels and a slip rate of the second set of drive wheels;
- and
- driving force distribution control means for controlling a distribution of driving force between the first set of wheels and the second set of wheels, based on the slip rate difference calculated by the slip rate difference calculating means.
