A camouflage composition includes a plurality of fabric strips, each strip having a body portion and at least one fringed portion, said at least one fringed portion arranged along a margin of the strip, the first surface of the body portion of each fabric strip affixed to the first surface of the body portion of a separate one of said plurality of fabric strips along a seam, said seam being oriented adjacent said fringed portion of each strip, whereby the body portions of each of said plurality of fabric strips form a continuous material and said fringed portions extend outwardly from said continuous material to form a three-dimensional camouflage effect. A garment made at least in part of the camouflage composition and a method of making the camouflage composition are further included.

Camouflage composition and method of making

A brake system control for use in a vehicle with four wheels comprising the steps of: determining a desired yaw rate (,); determining a yaw torque command responsive to the desired yaw rate (,); if the vehicle is in an anti-lock braking mode during driver commanded braking, applying the yaw torque command to only one of the four wheels to release brake pressure in said one of the four wheels (,); if the vehicle is in a positive acceleration traction control mode during driver commanded acceleration, applying the yaw torque command to only one of the four wheels to apply brake pressure in said one of the four wheels (,); and if the vehicle is not in the anti-lock braking mode or in the positive acceleration traction control mode, then: (i) determining whether a vehicle brake pedal is depressed (,); (ii) if the vehicle brake pedal is depressed, applying brake force to the vehicle wheels responsive to the depression of the brake pedal (,), wherein the applied brake force is modified to at least two of the vehicle wheels to create a left-right brake torque differential responsive to the yaw torque command.

Brake control system

A sensor-responsive control method for use on a motor vehicle, comprising the steps of: measuring a vehicle yaw rate; measuring a vehicle lateral acceleration; responsive to the measured yaw rate and lateral acceleration, estimating a steering wheel angle; determining an error signal responsive to the difference between the estimated steering wheel angle and an adaptive steering position signal; and updating the adaptive steering position signal responsive to the error signal, wherein the adaptive steering position signal is quickly determined after the vehicle begins to move.

Sensor-responsive control method and apparatus

A brake control system method according to the steps of: determining driver commanded yaw rate; measuring actual yaw rate; determining a yaw rate error; determining, in response to vehicle conditions, a yaw rate dead band wherein the yaw rate dead band varies with vehicle conditions; comparing the yaw rate error to the dead band; and if the yaw rate error exceeds the dead band, controlling the vehicle responsive to the yaw rate error, wherein yaw rate control only occurs when the yaw rate error exceeds the dead band.

An antilock brake controller provides an adaptive pressure hold period that interrupts the release of brake pressure during the pressure release phase of an antilock braking pressure control cycle of a vehicle wheel by holding the brake pressure constant while the wheel slip rate is below a threshold that is adjusted as a predetermined function of wheel slip for the front wheels and as a predetermined function of wheel acceleration for the rear wheels.

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.

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.

Antilock brake controller with brake mode filter

A method for determining an accurate vehicle speed, based upon the wheel speed data, for vehicle antilock systems in which the integrity of each individual wheel speed value is verified before including that wheel speed value in the reference speed calculation. Reference speed is then computed as a function of only those wheel speed values which have been successfully accepted into the calculation.

ABS Reference speed determination

An anti-lock braking control system is described in which the braking pressure cycle is filtered by limiting the minimum time period of each brake pressure cycle. The period from the time a brake pressure release phase is initiated until the next brake pressure release phase is called for is timed. If the time is less than a predetermined value, the brake pressure is held constant until the minimum time period has expired.
