摘要： An apparatus for controlling a variator having at least one roller between two torroidal disks may include at least one actuator responsive to fluid pressure at separate high side and low side fluid inlets thereof to control torque applied by the at least one roller to the disks. First and second variator switching valves may each receive a first fluid at a first pressure and a second fluid at a second lesser pressure. The first and second variator switching valves supply the first fluid to the high side fluid inlet and the second fluid to the low side fluid inlet during two of four different operational states together defined by the variator switching valves, and supply the second fluid to the high side fluid inlet and the first fluid to the low side fluid inlet during each of the remaining two of the four different operational states.

摘要： A hydraulic system for a hybrid module which is located between an engine and a transmission includes a parallel arrangement of a mechanical pump and an electric pump. Each pump is constructed and arranged to deliver oil to other portions of the hydraulic system depending on the operational mode. Three operational modes are described including an electric mode, a transition mode, and a cruise mode. Included is a lube splitter valve which prioritizes the delivery of oil between downstream components and the motor (eMachine). The motor temperature is monitored and an elevated motor temperature provides an indication of a clogged oil filter.

摘要： A hydraulic system includes a main modulation control scheme which relies in part on the use of a VBS solenoid and the multiplexing of that solenoid. The hydraulic system is associated with a hybrid module and by controlling the main pressure at a reduced level, the fuel economy and reliability of that hybrid module are improved. The system pressure is controlled by the multiplexed VBS solenoid in order to maintain adequate clutch pressure based on torque requirements. The overall system cost is reduced by the multiplexing of valves and solenoids.

摘要： A variator lockout valve system for a continuously variable transmission includes a pair of shift valves. Each shift valve has at least one port that is fluidly coupled to a variator of the continuously variable transmission. Electro-hydraulic actuators control the position of each of the shift valves. When the shift valves are in one position, pressure control valves supply fluid pressure to the variator. If one of the shift valves is in another position, one of the pressure control valves is blocked from supplying fluid pressure to the variator.

摘要： A transmission includes an electro-hydraulic controller that includes redundancy in the hydraulic circuit that permits single fault failures to be compensated for by changing the flow path of hydraulic fluid to bypass the single fault failure. The redundancy results in the ability of the transmission to maintain full operation in all modes.
