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.

摘要： Improved control for a hydraulic system pump motor useful in automotive braking applications, particularly in motor-based ABS, includes a routine for controlling a pump motor so that it is operated in a manner that is not disturbing to automotive vehicle occupants. In particular, the control routine of the present invention controls pump motor operation after an ABS braking event so that the motor is running only when the motor noise is masked by the pulsing of the ABS solenoids or after driver braking pressure is released from the master cylinder. In this way, the amount of objectionable noise transmitted to the automotive vehicle occupants is reduced, while important ABS pump functions, such as the draining of the accumulators following an ABS braking event, are facilitated.

摘要： A system and method for ABS stability control is provided, the method comprising the steps of determining whether a first wheel is in an ABS mode; determining whether the first wheel is in an apply mode; determining whether a second parallel wheel is in the release mode; calculating an adjusted wheel slip if the first wheel is in the ABS mode, the first wheel is in the apply mode, and the second parallel wheel is in the release mode; and determining a control mode for the first wheel using the adjusted wheel slip.
