  • Patent number: 7272478
    Abstract: The present invention provides a device for dynamically counteracting torque steer which includes a processor adapted to calculate a correction factor from a calculated axle torque on front wheel drive half shafts of the vehicle. A power circuit is provided responsive to the calculated correction factor to provide an offset current through the power steering unit or the braking system of the vehicle to counteract the torque steer.

  • Patent number: 7237433
    Abstract: A tire pressure monitoring system for a vehicle having a plurality of inflatable tires includes a plurality of rotation sensors that generate rotation signals based on a rotation of each of the tires and a pressure sensor that is responsive to a pressure within one of the tires and that generates a pressure signal based on the pressure. A control module receives the pulse signals and the pressure signal and that detects a low pressure condition of at least one of the tires based on the pressure signal and the pulse signals.

  • Patent number: 7218209
    Abstract: A method and apparatus are provided for determining pressure within a tire mounted to a vehicle, wherein the tire is coupled to a tire pressure monitoring system including a sensor coupled to a transmitter, the sensor configured to sense tire pressure and the transmitter configured to transmit the sensed tire pressure to a receiver. First, a first tire pressure is sensed. Then, a calculation is made as to whether the sensed first tire pressure is greater than a predetermined pressure threshold, equal to the predetermined pressure threshold, or less than the predetermined pressure threshold. Next, an indication is provided external to the vehicle that the sensed first tire pressure is greater than a predetermined pressure range, within the predetermined pressure range, or less than the predetermined pressure range.

  • Patent number: 7204114
    Abstract: A method of progressive hydro-forming of a tubular member includes the steps of positioning a tubular member between open die halves mating with one another to define a first tubular cavity portion in a first stage. The method also includes the steps of progressively closing the die halves and applying hydraulic pressure to expand and conform the tubular member to the first tubular cavity portion in the first stage. The method includes the steps of positioning the expanded tubular member in a second tubular cavity portion in a second stage and progressively closing the die halves to progressively deform the expanded tubular member within the second tubular cavity portion. The method includes the steps of applying hydraulic pressure to expand and conform the expanded tubular member to the second tubular cavity portion in the second stage.
