    摘要: A powertrain has an electrically variable hybrid transmission having an electro-hydraulic control system, plurality of electrical power units, and a plurality of torque transmitting mechanisms selectively engageable by the electro-hydraulic control system to provide four forward speed ranges, a neutral condition, an electric low and high speed mode, and an electrically variable low and high speed mode. Additionally, the electrically variable hybrid transmission provides a parallel reverse mode and a series reverse mode. The present invention provides an improved electro-hydraulic control system having a multiplexed electronic transmission range selection (ETRS) and reverse dog clutch system for an electrically variable hybrid transmission. The multiplexed control system of the present invention allows effective control of both the ETRS system and reverse dog clutch system using only one solenoid valve.

    摘要: A powertrain has an electrically variable hybrid transmission having an electro-hydraulic control system, plurality of electrical power units, and a plurality of torque transmitting mechanisms selectively engageable by the electro-hydraulic control system to provide four forward speed ranges, a neutral condition, an electric low and high speed mode, an electrically variable low and high speed mode, and a hill hold mode. The electro-hydraulic control system permits operation in the electrically variable low mode of operation if the electrical power is interrupted when the powertrain is operating in the first forward range, electric low speed mode, electrically variable low speed mode, and hill hold mode. Additionally, the system permits operation in the electrically variable high speed mode of operation if the electrical power is interrupted when the powertrain is operating in the second through fourth forward range, electric high speed mode, and electrically variable high speed mode.

    摘要: An apparatus for controlling a variator having at least one roller between two toroidal 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 variator fault detection system for a continuously variable transmission is incorporated into a hydraulic control circuit that controls fluid pressure applied to a variator of the continuously variable transmission. The hydraulic control circuit for the variator includes a number of electrically-controlled shift valves and pressure control valves. Sensing devices are multiplexed to these valves to detect a number of different possible fault states relating to the variator shift valves and the variator pressure control valves.
