Abstract
In an accelerator slip control device for a motor vehicle of the present invention, when the opening .theta. mw of a main throttle valve 8 has exceeded a standby starting opening .theta. sb at which the occurrence of acceleration slip is predicted, the opening .theta. sn of a sub-throttle valve 12 is set to a standby opening .theta. ss. These standby starting opening .theta. sb and standby opening .theta. ss are learned and updated on the basis of the driving torque of an internal combustion engine 2 when the acceleration slip is being controlled at an optimum value by acceleration slip control executed in the past, thereby enabling preventing the occurrence of excessive acceleration slip. Furthermore, when the occurrence of the acceleration slip is predicted, even before the occurrence of the acceleration slip, it is possible to reduce the time required to drive the sub-throttle valve 12 to a target opening of the acceleration slip control, at the time of occurrence of the acceleration slip, because the opening of the sub-throttle valve 12 is preset to the standby opening .theta. ss which is suitable for restraining the acceleration slip.
