摘要： An actuation system for actuating a clutch piston of a transmission includes an actuator and a lever. A first end of the lever is attached to the actuator. The lever is pivotable about a lever connection location. Movement of the actuator rotates the lever about the lever connection location. A spring assembly is pivotable about a spring connection location, and pivotably connected to the lever at a second end of the lever. When the actuator is disposed in an un-actuated position, the spring assembly is positioned such that a pre-loaded spring force is directed along a zero moment path to generate a zero moment in the lever. When the actuator is disposed in an actuated position, the spring assembly is rotated so that the spring force is directed along a moment generating path in order to generate a moment in the lever to rotate the lever.

摘要： Presented are intelligent vehicle systems and control logic for predictive route planning and adaptive control, methods for manufacturing/operating such systems, and motor vehicles with real-time eco-routing and automated driving capabilities. A method for controlling operation of a vehicle includes determining vehicle origin and destination information, and identifying candidate routes for traversing from the origin to the destination. Road-level data, including speed and topology data, is received for each candidate route. Total energy uses are estimated for propelling the vehicle from the origin to the destination across each of the candidate routes. This estimating includes evaluating respective road-level data of each candidate route against a memory-stored table that correlates energy consumption to speed, turn angle, and/or gradient. A resident vehicle controller commands a resident vehicle subsystem to execute a control operation based on one or more of the estimated total energy uses corresponding to one or more of the candidate routes.

摘要： A transmission includes a continuously variable unit and a fixed-gear-ratio unit. The continuously variable unit includes a variator input, and a variator output that is continuously connected to the transmission output member. A first torque transmitting mechanism interconnects the variator input and a transmission input member. The fixed-gear-ratio unit includes a single planetary gear set having a ring gear, planet gears supported by a carrier, and a sun gear. The fixed-gear-ratio unit includes a fixed input and a fixed output. The fixed input is continuously connected to the transmission input member, and one node of the planetary gear set. The fixed output is continuously connected to the transmission output member, and is selectively connected to another node of the planetary gear set. The fixed-gear-ratio unit includes second, third, fourth, and fifth torque transmitting mechanisms that are selectively engageable and/or disengageable for changing between fixed gear ratios.

The fixed-gear-ratio transmission includes first and second planetary gear sets and a plurality of transmission clutches, wherein the first and second planetary gear sets are arranged to transfer torque between an input member and an output member in one of first and second fixed-gear-ratio modes by selectively activating the transmission clutches. The torque transmission device operates in a first fixed overdrive input/output speed ratio when the CVU input clutch is deactivated and a first set of two of the transmission clutches is activated. The torque transmission device operates in a second fixed overdrive input/output speed ratio when the CVU input clutch is deactivated and a second set of two of the transmission clutches is activated.

摘要： A continuously-variable transmission (CVT) assembly is employed for transmitting a torque from an external power-source. The CVT includes a variable-diameter input pulley and a variable-diameter output pulley, each having a respective range of adjustment. The CVT also includes a continuous torque-transmitting element extending between the variable-diameter input pulley and the variable-diameter output pulley, and thereby operatively connecting the input pulley to the output pulley. The CVT additionally includes a first elastic element having a first zero stiffness over the range of adjustment of the variable-diameter input pulley and configured to apply a first constant spring clamping force via the input pulley to the continuous torque-transmitting element. Furthermore, the CVT includes a second elastic element having a second zero stiffness over the range of adjustment of the variable-diameter input pulley and configured to apply a second constant spring clamping force via the output pulley to the continuous torque-transmitting element.
