PURPOSE:To improve the traveling performance on a split mu road by selecting the less speed among the right and left drive wheel speed and calculating the actual slip rate from the selected drive wheel speed and the driven wheel speed and executing the drive power reduction control. CONSTITUTION:In a car speed detecting device equipped with a differential limit mechanism (c) between the right and left drive wheels (a) and (b), the right and left drive wheel speed detecting means (d) and (e) for detecting the revolution speed of the right and left drive wheels (a) and (b) in a driven wheel speed detecting means (f) for detecting the revolution speed of the driven wheel are installed. A drive wheel speed selecting means (g) calculates the actual slip rate between a tire and road surface by an actual slip rate calculating means (h) from the selected drive wheel speed and the driven wheel speed. The actual slip rate is compared with a prescribed set slip rate, and when the actual slip rate exceeds the set slip rate, a drive power control means (i) executes the drive power reduction control, and the drive wheel slip is suppressed. |
