  • Patent number: 11198440
    Abstract: A control system and method for controlling a multiple gear ratio automatic transmission in a powertrain for an automatic transmission having pressure activated fiction torque elements to effect gear ratio upshifts. The friction torque elements are synchronously engaged and released during a torque phase of an upshift event as torque from a torque source is increased while allowing the off-going friction elements to slip, followed by an inertia phase during which torque from a torque source is modulated. A perceptible transmission output torque reduction during an upshift is avoided. Measured torque values are used during a torque phase of the upshift to correct an estimated oncoming friction element target torque so that transient torque disturbances at an oncoming clutch are avoided and torque transients at the output shaft are reduced.

  • Patent number: 8820501
    Abstract: A pumping device for a vehicle seat cushion, which rotates a link gear mounted to the seat cushion as an actuating lever is rotated, thereby controlling the height of the seat cushion. This pumping device generates a uniform clutch force at the same position at all times and prevents undesired movement of the actuating lever so that the actuating lever can be located at the regular position at all times. In addition, when operating the actuating lever in the same direction continuously, the pumping device can minimize the degree of angle at which the actuating lever idles, so that the pumping device can improve the controllability of the actuating lever, thereby effectively transmitting the operating force of the actuating lever to the link gear. Therefore, this invention causes the user inconvenience and improves the quality of the vehicle seat, and remarkably improves assemblability and productivity of the pumping device.

    Abstract: A pumping device for a vehicle seat cushion, which rotates a link gear mounted to the seat cushion as an actuating lever is rotated, thereby controlling the height of the seat cushion. This pumping device generates a uniform clutch force at the same position at all times and prevents undesired movement of the actuating lever so that the actuating lever can be located at the regular position at all times. In addition, when operating the actuating lever in the same direction continuously, the pumping device can minimize the degree of angle at which the actuating lever idles, so that the pumping device can improve the controllability of the actuating lever, thereby effectively transmitting the operating force of the actuating lever to the link gear. Therefore, this invention causes the user inconvenience and improves the quality of the vehicle seat, and remarkably improves assemblability and productivity of the pumping device.

  • Patent number: 8051967
    Abstract: The seat adjustment mechanism has a housing with an outer ring and an inner ring. The rings are arranged concentrically. Clamping bodies interact with double clamping ramps on the rings and are arranged in an annular space between the rings. Spring supports pivot in relation to each other, interact with a stop on the housing, are arranged concentrically with the rings, and engage in each case both in the annular space and in an inner space arranged radially within the inner ring. The spring supports are braced in relation to each other by a spring, which is arranged in the inner space to secure the clamping bodies in the center of the double clamping ramps. Stop surfaces of the spring supports are acted upon by a force in the direction in which they are minimally spaced apart.

  • Patent number: 7684918
    Abstract: The invention relates to a PTO brake control system. There is a need for an improved and safe PTO brake control system. A PTO may be put into a driven and a non-driven condition an is braked by a PTO brake. A PTO brake control system includes a vehicle speed sensor and an ECU for controlling the PTO brake. The ECU deactivates the PTO brake when the vehicle is stationary and the PTO is not driven. This allows the PTO to be manually rotated to facilitate coupling of the PTO to an implement.
