| 20100113214 | Method and Apparatus For Optimizing Braking Control During A Threshold Braking Event - A method minimizes a driveline vibration and reduces stopping distances in a hybrid electric vehicle (HEV) having a plurality of drive wheels, a friction braking system having antilock braking system (ABS) capability, and an electronically variable transmission (EVT) with two EVT modes. The method automatically shifts the EVT to a predetermined high speed/low torque EVT mode when the ABS is active and when a calibrated maximum deceleration rate is not exceeded. An HEV has a friction braking system with ABS capability and an EVT including a plurality of modes. A controller automatically activates the friction braking ABS in response to a threshold level of slip between the drive wheels and the road surface when the brake pedal is actuated. An algorithm automatically shifts the EVT into one of the high speed/low torque EVT modes when the ABS is activated and the calibrated maximum deceleration rate is not exceeded. | 05-06-2010 |

| 20100062897 | Brake Control System - Provided is a brake control apparatus for a vehicle which detects an amount of brake-pedal operation by means of an electric signal, and then calculates a braking force demanded by a driver from the electric signal, and thereby generates the demanded braking force. A control mode for a braking force is switched from a normal control mode to a stationary-vehicle control mode, if a determination that the vehicle is in a stationary state is followed by another determination that an electric signal corresponding to an actual braking force exceeds a command value for a stationary-vehicle braking force while the vehicle is in the stationary state. The control mode for a braking force is switched from the stationary-vehicle control mode to the normal control mode, if it is determined that the demanded braking force becomes smaller than the command value for the stationary-vehicle braking force. In addition, in the stationary-vehicle control mode, a braking force generated by a means for braking is equal to the command value for the stationary-vehicle braking force, whereas, in the normal control mode, the braking force generated by the means for braking is equal to the braking force demanded by the driver. | 03-11-2010 |

| 20100113215 | METHOD FOR OPERATING A VEHICLE BRAKE SYSTEM AND VEHICLE BRAKE SYSTEM - A method for operating a vehicle brake system and a corresponding vehicle brake system, particularly for motor vehicles. The vehicle wheels of the motor vehicle associated with an axle are at least partially driven by ‘WV’ an electric motor that can be operated as a generator during regeneration of braking energy, thus exerting a braking regeneration el torque on the respective axle. To prevent overbraking on the rear axle, the regeneration torque acting on at least one rear axle (HA) is limited such that the slippage present on the at least one vehicle wheel of the rear axle (HA) does not exceed or only negligibly exceeds a first slippage threshold individually associated with the respective vehicle wheel. | 05-06-2010 |
