Abstract: The distribution of drive power produced by a drive power source is controlled in a four-wheel-drive motor vehicle having main drive wheels and auxiliary drive wheels. Drive powers produced by the drive power source are independently regulated and transmitted to the left and right auxiliary drive wheels. While the drive power distribution ratio between the main and auxiliary drive wheels is maintained at a suitable value, the drive powers are variable distributed between the left and right auxiliary drive wheels by a drive power distribution control system. The drive power distribution control system determines the drive power distribution ratio between the left and right auxiliary drive wheels depending on a detected lateral acceleration exerted to the motor vehicle, and transmits the drive powers to the left and right auxiliary drive wheels according to the determined drive power distribution ratio.
