Title:
ACCELERATION SLIP CONTROLLER FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/1993/000507
Kind Code:
A1
Abstract:
When the opening mw of a main throttle valve (8) exceeds a stand-by start opening sb at which the occurrence of an acceleration slip is anticipated, the opening sn of a sub-throttle valve (12) is set to the stand-by opening ss. These stand-by openings sb and ss are learned and updated on the basis of a driving torque of an internal combustion engine (2) whose acceleration slip is controlled to an appropriate value by the acceleration slip control that was executed in the past. Therefore, the occurrence of an excessive acceleration slip can be prevented beforehand. Furthermore, if the occurrence of the acceleration slip is anticipated, the opening of the sub-throttle valve (12) is in advance set to the stand-by opening ss suitable for suppressing the acceleration slip. When the acceleration slip occurs, therefore, the time necessary for driving the sub-throttle valve (12) to the target opening of the acceleration slip control can be shortened.
