Abstract: The present invention is a method and system to control regenerative braking during the operation of a yaw stability control system. The method and system use feedback control algorithms to monitor and dynamically modify regenerative and non-regenerative braking. The controller can use a simple proportional-integral-derivative feedback controller. A vehicle yaw stability control system can determine if a vehicle is experiencing an oversteer or understeer condition. The controller compares actual brake balance to a desired brake balance. The controller determines if the front axle wheels are overbraked relative to the rear axle wheels or if the rear axle wheels are overbraked relative to the front axle wheels as compared to the desired brake balance. The controller can adjust regenerative braking and non-regenerative braking levels according to the determinations.

Abstract: Disclosed are hair styling compositions which comprise from about 5% to about 90% by weight of a polyalkylene glycol styling agent that is substantially free of polyalkylene glyceryl ethers, and that has a number average molecular weight of from about 190 to about 1500 and from about 5 to about 35 repeating alkylene oxide radicals wherein each of the repeating alkylene oxide radicals has from 2 to 6 carbon atoms; from about 1% to about 90% by weight of a liquid carrier which can comprise water, an organic solvent, or combinations thereof; and, optionally, from about 5% to about 40% by weight of a propellant.

Abstract: Hair care compositions comprise a water-soluble polyalkylene glycol having a number average molecular weight of from about 200 to about 900 and from about 4 to about 18 repeating alkylene oxide radicals, wherein each of the repeating alkylene oxide radicals has from 2 to 6 carbon atoms; a film forming polymer is soluble in the polyalkylene glycol, wherein the weight ratio of the polyalkylene glycol to the film forming polymer ranges from about 5:1 to about 50:1; and a liquid carrier. The hair care compositions optionally further comprise a non-volatile silicone with a molecular weight greater than about 40,000 daltons.

Abstract: A brake assembly 12 for use within an electric vehicle 10 and which allows the vehicle 10 to be selectively decelerated in substantially the same manner as is an internal combustion engine type vehicle upon the release of an accelerator pedal member 18 or the depression of a brake member 20.

Abstract: A method and apparatus for providing regenerative and friction braking on a vehicle having one or more wheels driven by a drive motor includes a master cylinder (28), a hydraulic control unit (30), a brake control unit (38), a drive motor control unit (52) and a drive motor (18). The drive motor control unit determines a coast down regenerative torque signal and a driver brake command regenerative torque signal and commands the drive motor to regeneratively brake the driven left and right wheels in response to whichever of the coast down regenerative torque signal and the driver brake command regenerative torque signal is greatest, thereby maintaining a desirable proportioning of front to rear braking.

The brake control unit commands build and dump valve pairs (31, 35) such that brake forces generated at the driven left and right wheels (14, 16) are a combination of the regenerative braking and hydraulic braking, the hydraulic braking being gradually reduced and the regenerative braking being gradually increased during transitions from anti-skid braking control to wheel speed based proportioning and regenerative braking control.
