Patent ID: 7316630

Claim:
A control apparatus for a belt-type continuously variable transmission connected to an engine, the continuously variable transmission having a starting clutch, a driving shaft, an input shaft operatively connected to a crankshaft of the engine through the starting clutch, and an output shaft fixedly connected to the driving shaft and coaxial therewith, wherein the crankshaft rotates in a first direction of rotation during normal engine operation; wherein the starting clutch is adapted to operatively connect the transmission to the crankshaft when a speed of the crankshaft exceeds a predetermined value, thus allowing power of the engine to be transmitted to the driving shaft through the continuously variable transmission, wherein the control apparatus comprises: a first one-way clutch disposed between the output shaft of the continuously variable transmission and the driving shaft, the first one-way clutch being capable of rotating idly relative to a backward drive of the output shaft; a gear ratio detector for detecting a gear ratio of the continuously variable transmission; an engine state detector for detecting whether the engine is stationary or moving; and a crankshaft driver which is capable of selectively and temporarily driving the crankshaft in a direction opposite to the first direction of rotation thereof such that the belt of the continuously variable transmission rotates backward, when the engine is in a stationary state, and the gear ratio of the continuously variable transmission is greater than a predetermined reference value.
