Summary: | A belt-type continuously variable transmission changes winding radii of a belt that is wound around an input-side and an output-side pulley to shift speeds. The belt-type continuously variable transmission is mounted on a vehicle that switches between two-wheel drive is transmitted only to front wheels and four-wheel drive. An electronic control unit that controls the belt-type continuously variable transmission adjusts the belt clamping pressure of each pulley as torque is distributed to the rear wheels, to suppress muffled noise due to resonance of vehicle components with belt span vibrations. |
