Acceleration slip control device for a wheeled vehicle
First Claim
Patent Images
1. A control system for preventing a slip comprising:
- slip detection means for detecting a driving wheel speed and providing a first signal corresponding thereto and for determining whether or not said slip occurs based on said first signal;
engine intake air volume estimation means for estimating an intake air volume of an internal combustion engine and providing a second signal corresponding thereto;
desired engine output determination means, receiving said first and second signals when said slip occurs for determining a desired engine output in response to at least said first signal and modifying said desired engine output in response to said second signal; and
engine output control means responsive to said desired engine output determination means for controlling an engine output to approach said modified desired engine output.

Abstract
The invention relates to an acceleration slip control device, wherein the control quantity for the throttle valve angle operation is determined not only in response to the slip condition but also to the output torque changeability of the internal combustion engine with regard to the throttle valve angle displacement, therefore the output torque of the engine can be effectively restrained to the optimum value counteractive to the slip condition of the driving wheels.
