  • Patent number: 6834838
    Abstract: A selectively deployable cupholder that incorporates the best aspects of the static and active component cupholder designs, composed of stationary cylindrical component and a movable cylindrical component that is telescopically nested within the stationary cylindrical component. When the movable cylindrical component is in an undeployed state, whereat it is fully nested with respect to the stationary cylindrical component, a low vertical profile is provided, suitable for drawer applications. When the movable cylindrical component is in a deployed state, whereat it is fully telescopically raised relative to the stationary cylindrical component, the cupholder receives beverage containers with a stable support as is required for the automotive driving environment.
    Type: Grant

  • Patent number: 5184299
    Abstract: A motor speed controller for an antilock brake system motor driven brake pressure modulator controls the speed during the pressure ramping phase of an antilock brake pressure control cycle by commanding periods of dynamic braking of the motor while the motor current is being controlled to ramp the pressure.

  • Patent number: 5147115
    Abstract: In an antilock braking system, when wheel parameters including slip represent an incipient wheel lockup condition normally calling for a release of brake pressure during a pressure apply mode of an antilock braking cycle and the duration of the pressure apply mode is less than a predetermined threshold representing an abnormal rapid cycling of the brake pressure, the wheel slip threshold representing an incipient wheel lockup condition is increased, the rate of increase in brake pressure during the brake pressure apply mode is set to a high level and the pressure apply mode is continued during which the wheel brake pressure is ramped at the increased rate. These steps are repeated while the wheel parameters represent an incipient wheel lockup condition normally calling for a release of brake pressure until the time of the pressure apply mode equals the predetermined threshold representing a normal brake pressure cycling period.

  • Patent number: 5106171
    Abstract: The current to the motor of a motor driven pressure modulator of an antilock brake system is controlled at a high value in response to a sensed incipient wheel lock condition so as to rapidly release the brake pressure for a calibrated time period that is a function of wheel parameters to reduce brake pressure by an amount determined to effect a recovery from the incipient wheel lock condition under normal antilock controlled braking. After the calibrated time period, the motor is braked so as to quickly halt its rotation and therefore the rapid pressure reduction by applying a motor brake current to the motor by controlling the motor current in the pressure apply direction. The duration of this rapid reduction of brake pressure and therefore the amount of pressure reduction is independent of a sensed recovery condition of the wheel and is based solely on an open loop calibration value determined to effect wheel recovery from the incipient wheel lock condition.

  • Patent number: 5102207
    Abstract: The period of an initial apply motor current in each apply phase of an antilock brake pressure cycle in a motor driven pressure modulator antilock braking system is adaptively controlled following a sensed recovery from an incipient wheel lockup condition to establish substantially a steady state condition relationship between current and pressure before motor current is ramped to ramp brake pressure. The period of the initial apply motor current is made a function of the amount of pressure decrease during a prior release phase portion of the antilock brake cycle to account for the greater increase in brake pressure to the initial reapply value.

  • Patent number: 5080447
    Abstract: A schedule of brake pressure ramp rates is provided in a vehicle antilock brake controller as a function of predetermined wheel parameters. The ramp rates associated with the specific values of the wheel parameters are filtered by limiting the changes in ramp rate to a next higher ramp rate from the schedule of rates when the ramp rate called for by the wheel parameters is greater than the present ramp rate and to a next lower ramp rate from the schedule of rates when the ramp rate called for by the wheel parameters is less than the present ramp rate.
