摘要： The electrically variable transmission family of the present invention provides low-content, low-cost electrically variable transmission mechanisms including first, second and third differential gear sets, a battery, two electric machines serving interchangeably as motors or generators, and four selectable torque-transfer devices (two clutches and two brakes). The selectable torque transfer devices are engaged singly or combinations of two to yield an EVT with a continuously variable range of speeds (including reverse) and four mechanically fixed forward speed ratios. The torque transfer devices and the first and second motor/generators are operable to provide five operating modes in the electrically variable transmission, including battery reverse mode, EVT reverse mode, reverse and forward launch modes, continuously variable transmission range mode, and fixed ratio mode.

摘要： A family of transmissions includes three planetary gearsets and five torque-transmitting mechanisms. Each family member may be employed in a powertrain to provide six forward speed ratios and one reverse speed ratio when the torque-transmitting mechanisms are engaged in combinations of two in a selected manner. Each planetary gearset includes three planetary members; namely, a sun gear, a ring gear, and a planet carrier assembly member. The first member of the first planetary gearset is continuously connected with the first member of the second planetary gearset. The second member of the first planetary gearset is continuously connected with a first member of the third planetary gearset. The second member of the second planetary gearset is continuously connected with the second member of the third planetary gearset. An input shaft is continuously connected with one of the members of the planetary gearsets and an output shaft is continuously connected with another member of the planetary gearsets. Three of the torque-transmitting mechanisms are of the selectively engageable stationary type torque-transmitting mechanisms, or brakes, and two of the torque-transmitting mechanisms are rotating type torque-transmitting mechanisms, or clutches.

摘要： A system and method for providing energy to auto systems such as systems after-treating exhaust. Energy may be received from a solar energy source electrically connected to an after-treatment system. At least some of the energy from the solar energy source may be provided to the after-treatment system to purify exhaust from an engine. A control module may provide at least some of the energy from the solar energy source to a heater, for example, to initiate heating the after-treatment system prior to starting the engine. The heater may heat the after-treatment to temperatures within a predetermined temperature range associated with optimal efficiency for the after-treatment system.

摘要： A multi-speed transmission includes an input member, an output member, a stationary member, and a first and a second compound planetary gear set. The first compound planetary gear set has a first, a second, a third, a fourth, and a fifth member. The second compound planetary gear set has a first, a second, a third, and a fourth member. The first member of the second compound planetary gear set is continuously connected for common rotation with the output member. An interconnecting member continuously connects the first member of the first planetary gear set for common rotation with the second member of the second planetary gear set. The transmission includes seven torque-transmitting mechanisms that are engagable to establish up to fifteen forward speed ratios between the input member and the output member.
