<p>PROBLEM TO BE SOLVED: To achieve highly precise control without cost increase while detecting both oil pressures of hydraulic actuators in a primary side and a secondary side with one oil pressure sensor.SOLUTION: Both oil pressures of hydraulic actuators 33, 35 in a primary side and a secondary side are controlled by respective valves 82, 83 to allow a belt type non-stage transmission to change speed with an appropriate belt holding pressure. A switch valve 93 switches communication of an oil pressure sensor 78 to either one of the hydraulic actuators 35, 33.</p> |
