Abstract:
1. An apparatus for controlling the driving force of a vehicle, comprising: drive wheels configured to receive torque from a drive source; a differential mechanism arranged between the drive source and the drive wheels, configured to allow differential rotation between the drive wheels and transmit torque from the drive source to the drive wheels; brakes, each one of said brakes corresponding to one of the drive wheels, and configured to selectively provide a braking force to the corresponding one of the drive wheels; a driving force controller configured to control at least one of the brakes and limit differential rotation between the drive wheels; a differential limiting mechanism provided for the differential mechanism; and a torque transmission coupling, wherein the differential mechanism receives torque from the drive source through the torque transmission coupling, and where “i” is a final reduction ratio between the torque connect/disconnect mechanism and one of the front and rear differential mechanisms on the secondary drive side, “Rt” is a torque bias ratio set for the differential mechanism on the secondary drive side, “TB” is braking torque achieved by the brakes, and “TEM” is torque transmitted through the torque transmission coupling.
