<p>Subject : Assist-cut is to be made effectively in a state not requiring assist and assist is to be started at a medium treading force level. Solving Means : As treading force level detecting means for detecting that a treading force is at an assist-cut level there are used a treading force judging section (43), a low level counter (44), and a comparator (45). The treading force judging section detects the magnitude of the present treading force relative to a reference value of treading force, increments or decrements a count value (CNTBT) in accordance with the magnitude of the treading force, and makes assist-cut when the count value (CNTBT) becomes the reference value (TTED). As treading force changing level detecting means for detecting that the treading force is changing in the vicinity of a predetermined assist level there are used a peak value detector (46), a treading force level judging section (47), and an assist counter (48). Assist is started when it is judged from a count value of the counter (48) that the treading force level has exceeded the predetermined level continuously. <IMAGE></p> |
