  • Damper for a vehicle torque transferring assembly
    Patent number: 7083523
    Abstract: A lightweight damper for reducing noise and vibration in torque transferring assemblies that is easily assembled and cost efficient. The damper may be formed from a foam material having a density less than 1.4 lb/ft3, and includes an outer surface that is resiliently biased against the inner surface of a tubular shaft when installed. In a second embodiment, the damper is formed from a sheet of material that dissipates energy such as noises and vibrations through movement of the layers relative to each other. In third embodiment, the dampening sheet and foam damper are combined to provide a damper that dampens noises and vibrations across a large frequency range.

  • Vehicle stability control
    Patent number: 6704622
    Abstract: Stability is an important factor in vehicle safety. Yaw rate error can be used to improve stability. Yaw rate is measured through a yaw rate sensor. Desired yaw rate can be determined from vehicle conditions and driver input. The yaw rate error is calculated by subtracting the measured yaw rate from the desired yaw rate. Based on this calculation, yaw torque target signals can be calculated to apply torque to the wheels through the application of one or more electric drivelines. The application of torque can provide side-to-side and front-to-rear torque biasing to improve stability. Furthermore, the application of torque at specific times can improve braking and launch capabilities.
