Latest Patents

Spencer Johnson holds a patent for "Transition control for low torque upshifts of an automatic transmission." This invention addresses the challenges associated with upshifting in automatic transmissions. According to one embodiment, a vehicle includes a transmission, a brake pedal, and a controller. The controller is programmed to, in response to an upshift of the transmission, a driver-demanded torque being zero, and the brake pedal being released, command a first pressure, that is greater than zero, to an oncoming shift element associated with the upshift such that the oncoming shift element has a torque capacity of zero. In response to the brake pedal being applied during the upshift of the transmission, the controller commands a second, larger pressure to the oncoming shift element to increase the torque capacity to a non-zero value. Furthermore, in response to the expiration of a threshold time from the brake pedal being applied, the controller commands a series of sequentially ramping pressures to the oncoming shift element to further increase the torque capacity and lock the oncoming shift element. This innovative solution improves the efficiency and responsiveness of automatic transmissions.
