Abstract: A pendulum crankshaft for an internal combustion engine includes a pendulum crankshaft having pendulum crank rolling path inserts that are cast into the component during the casting process. The rolling path inserts are positioned in a mold prior to casting.

The rolling path may be formed from a metal such as sintered powdered metal. The flowable material may be a metal such as iron. The resulting component is free of stress regions, such as on the carrier strap, that normally result from methods that involve press-fitting the rolling path insert into the component.

Abstract: A continuously variable transmission (100), wherein pressure equalization control is performed to make line pressure (PL) equal to secondary pressure (Psec) when prescribed start conditions are satisfied. During pressure equalization control, a secondary pressure indicated value (Psec_co) is raised by a prescribed amount (S10), then a line pressure indicated value (PL_co) is gradually decreased (S30). If determination is made that line pressure is the same as the secondary pressure after secondary actual pressure (Psec) is lowered (S40), then the line pressure is controlled so that the secondary actual pressure (Psec) becomes the secondary pressure indicated value (Psec_co) (S50). At the start of pressure equalization control, if the difference (?Psec) found by subtracting the secondary pressure indicated value from the secondary actual value is negative (S120), then a primary pressure indicated value is corrected on the basis of the difference (S130).
