    摘要: A transmission includes first, second, third, and fourth clutches, first and second shift valves, and first, second, third, and fourth trim valves. Each trim valve is operative to control fluid pressure to a respective one of the first, second, third, and fourth clutches. The transmission also includes a controller. The controller is electrically operatively connected to the first and second shift valves and the first, second, third, and fourth trim valves to selectively provide a first clutch configuration for operating in a first mode and a second clutch configuration for operating in a second mode. The transmission also includes a clutch control mechanization for selectively moving the clutch configuration to a default position in the event power to the transmission is lost.

    摘要: A hydraulic control system for distributing pressurized fluid to a multi-mode hybrid-type power transmission is provided, as well as a method for regulating the same. The hydraulic control system includes an engine-driven main pump in fluid communication with a main regulator valve, and an electrically-driven auxiliary pump in fluid communication with an auxiliary regulator valve. One pressure control solenoid provides feedback (boost) pressure to both regulator valves, and thereby modify output of the main and auxiliary pumps. A controller selectively modifies distribution of boost pressure to ensure a continuous and controllable feed of hydraulic pressure to the transmission during all vehicle operations. The method includes: determining if the vehicle is transitioning to engine auto-start or auto-stop; determining the line pressure requirements of the transmission under current operating conditions; starting the oncoming-pump; adjusting PCS command so started oncoming-pump pressure equals line pressure requirements; and shutting down off-going-pump.

    摘要: A fluid is supplied to a housing of a hybrid transmission. An overall system line pressure is elevated to induce leakage of the fluid through a control system. The leaked fluid is flowed through at least one backfill passage to the housing of the hybrid transmission. The leaked fluid is flowed over the motors disposed within the housing to cool the motors. The fluid that is flowed over the motors is collected to create a head pressure within the housing. The head pressure forces the collected fluid upwards within the transmission housing and into clutches that are disposed therein.

    摘要: A hydraulic control system for a multi-mode hybrid-type power transmission is provided, including an engine-driven main pump in fluid communication with a main regulator valve, and an electrically driven auxiliary pump in fluid communication with an auxiliary regulator valve. A first pressure control solenoid is configured to provide boost pressure to the main regulator valve and thereby boost output of the main pump. A second pressure control solenoid is configured to provide boost pressure to the auxiliary regulator valve and thereby boost output of the auxiliary pump. The distribution of boost pressure from the pressure control solenoids is selectively modified such that at least one of the flows of pressurized fluid from the pumps is equal to the current line pressure requirements of the transmission during engine auto-start and auto-stop, and transitions thereto. An improved method for regulating the hydraulic control system is also provided.

    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.

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.
