摘要： A method for estimating master cylinder pressure during brake apply of a brake system of a vehicle, wherein the brake system includes a brake pedal. A first master cylinder pressure is estimated from brake pedal position during brake apply. A second master cylinder pressure is estimated from vehicle deceleration during brake apply. The master cylinder pressure is estimated during brake apply to be equal to the first master cylinder pressure when the vehicle deceleration is below a predetermined deceleration value. The master cylinder pressure is estimated during brake apply to be equal to a value which is less than the first master cylinder pressure and greater than or equal to the second master cylinder pressure when the vehicle deceleration is at or above the predetermined deceleration value. At least the estimated master cylinder pressure during brake apply is used to control the vehicle.

摘要： A vehicle hydraulic braking system responds to detection of an operator intended high braking intensity event to isolate vehicle brakes from the master cylinder and activate a motor driven pump to generate a maximum predetermined supply pressure, calibrated to provide activation of an anti-lock braking system, to the brake apply valves for an initial predetermined time. Thereafter, the supply pressure is reduced via an electrically controllable pressure relief valve responsive to sensed vehicle deceleration so as to decrease the supply pressure provided to the apply valve to a level just sufficient to provide the sensed vehicle deceleration. The high intensity braking event is detected via a rate of change of master cylinder pressure, pedal force or pedal travel.

摘要： A method and device for brake application provides braking pressure augmentation when preferred. A power booster and master cylinder generate a braking pressure in relation to an operator's input on the brake pedal. An optional brake parameter sensor is used to determine when the power booster reaches a run-out condition. At least one control valve and pump are used to apply braking pressure in response to additional increases in brake pedal application by the operator, after the power booster reaches a run-out condition. The pump and control valve are optionally used to generate braking pressure independent of brake pedal inputs.

摘要： A substantially constant brake assist gain is provided in a vehicle braking system having a vacuum booster providing braking assist to a brake fluid master cylinder in response to an operator input braking force, even though the gain of the booster falls off from its maximum value in a non-linear manner in a runout initiating portion of the working vacuum range near zero booster vacuum. A brake fluid pump, such as is used in an ABS/TCS modulator, is used to supplement the booster output as it falls so as to maintain a constant, linear brake system gain into runout. In the runout initiating portion of the working vacuum range, a runout assist gain is derived from stored data expressing booster assist gain as a function of booster vacuum, and a target wheel pressure is calculated from the derived runout boost assist gain and a corresponding change in master cylinder pressure. A target wheel pressure error is calculated from the difference between the derived target wheel pressure and the master cylinder pressure and used to control the brake fluid pressure added by the pump to the master cylinder pressure.

摘要： Noise produced during a supplemental brake apply is reduced eliminated by reducing the quantity of additional brake fluid supplied to the pump during the apply. The prime valve is opened only at the initiation of the supplemental apply to supply a predetermined small quantity of brake fluid to the accumulator and pump inlet and is then closed for the remainder of the apply. The quantity of extra fluid supplied can be retained by the accumulator and does not need to by blown off back to the master cylinder. The apply valve of the non-regulated wheel brake is controlled to regulate pressure to the regulated wheel brake through the apply valve thereof, which is left open while the release valve of the regulated wheel brake is left closed. The release valve of the non-regulated wheel is controlled to maintain a lower pressure at the non-regulated wheel, preferably equal to the master cylinder pressure whenever possible, while permitting fluid flow back to the accumulator. The more even flow of this arrangement through the circuit permits operation with the smaller quantity of extra brake fluid. The reduction in blow-off events reduces objectionable noise produced by the blow-off valve when the vehicle operator initiates manual brake apply during a supplemental apply.
