ABSTRACT:
A wheel slip ratio correction apparatus is disclosed which includes a calculation unit for calculating a slip ratio of each wheel when the brakes are not applied to either a front wheel or a rear wheel of a mobile vehicle such as a motorcycle. The calculation unit calculates a difference between a front wheel slip ratio and a rear wheel slip ratio, and changes in the slip ratio difference, which occur within a predetermined time period, are monitored by detecting if the slip ratio difference is stable and is within a predetermined range for a predetermined period of time. If the slip ratio difference is stable and is within the predetermined range for the predetermined period of time, a correction value, dependent upon the slip ratio difference, is subtracted from the greater of the front wheel slip ratio and rear wheel slip ratio so that any undesirable difference between the front and rear wheel slip ratios may be eliminated.
