Patents by Inventor Keith W. Weishuhn

Keith W. Weishuhn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9664309
    Abstract: An apparatus is provided that mounts both a pump and either an inlet hose or an outlet hose for the pump to vehicle support structure. The pump has a pump housing with a pump inlet and a pump outlet. An inlet hose is attached to the pump inlet, and an outlet hose is attached to the pump outlet. The apparatus includes a compliant pump hose mount that has a hose attachment portion with a hose opening sized so that one of the inlet hose and the outlet hose is supportable by the pump hose mount at the hose opening. The pump hose mount also has a mount portion mountable to the vehicle support structure. The pump is thereby mounted to the vehicle support structure by the pump hose mount so that noise and vibration of the pump are mitigated by the pump hose mount.

  • Patent number: 9352739
    Abstract: A method for operating a hybrid vehicle, particularly one that includes both a primary and an auxiliary power source. According to one exemplary embodiment, the method seeks to decouple or disassociate a driver's engagement of an accelerator pedal with activation of an auxiliary power source, such as an internal combustion engine. This way, if the driver aggressively engages the accelerator pedal while the hybrid vehicle is being propelled by a battery and an electrical motor, the method will delay activation of the internal combustion engine so that the two events do not appear to be linked or connected to one another. Delaying activation of the internal combustion engine while the electric motor is under a heavy stress load may also improve the drive quality of the hybrid vehicle.

  • Patent number: 7509201
    Abstract: A method of controlling noise/vibration in a vehicle having a powertrain includes sensing noise/vibration in the vehicle. An operating point of the powertrain is adjusted and a constant transmission output power is maintained to reduce the noise/vibration.
