PURPOSE:To prevent a reslip from occurring by selecting a preset specified map in the case where control characteristic maps at that time when a slip factor has exceeded the setting value, and before the specified time both are in such a characteristic that an increment ratio of throttle opening/accelerator manipulated variable is highest. CONSTITUTION:A slip factor is calculated by an operational means (c) from driving wheel speed (a) and body speed (b). When this slip factor is less than the setting value, a map selecting means (g) is shifted to a host map where an increment ratio of throttle opening to an accelerator manipulated variable is raised more than the existing control characteristic map. On the other hand, when it is more than the setting value, both maps at that time and before the specified time are compared at each exceeding time, thereby selecting a smaller side in the increment ratio. When both maps are in the highest characteristic in the increment ratio, the map preset in a setting means (f) is selected, and according to this map, desired throttle opening (h) is set up, and thereby the throttle opening is controlled via a control means (j) and an actuator (i). Thus, a reslip is prevented from occurring. |
