摘要： An antiskid control system for a four-wheel-drive vehicle is arranged to calculate a difference between an average of wheel accelerations of front wheels and an average of wheel acceleration of rear wheels. When the difference is greater than or equal to the vibration determination threshold, the antiskid control system determines that a driveline vibration is generated and executes a control for converging the driveline vibration.

摘要： In an antiskid brake control system, an ECU is constructed to calculate a pseudo vehicle-body speed in accordance with a sensed wheel speed, calculate a target wheel speed in view of a predetermined slip ratio obtained in accordance with a calculated pseudo vehicle-body speed, carry out pressure reducing control by reducing the fluid pressure within a hydraulic unit when the sensed wheel speed is smaller than the calculated target wheel speed, estimate an amount of fluid stored in a reservoir, and correct the target wheel speed to lessen the slip ratio when the estimated fluid amount is greater than a predetermined value.

摘要： In a brake control apparatus for a vehicle, a left and right road friction coefficient estimating section calculates each of left and right estimated road surface friction coefficients from a relation between a pressure decrease control time in one cycle and a maximum wheel acceleration during the pressure decrease time. A split friction discriminating section discriminates a split friction road surface condition from a non-split condition in accordance with a difference between the left and right estimated road surface friction coefficients. A control modifying section modifies a brake fluid pressure control for a wheel cylinder to differentiate brake control characteristics for left and right wheels from each other in the case of the split friction road surface condition.

摘要： In an antiskid brake control system, an ECU estimates a wheel slip in accordance with a sensed wheel speed and controls a fluid pressure control valve for braking operation in accordance with the estimated wheel slip for an antiskid brake control, the fluid pressure being reduced when the wheel slip is enlarged and being increased when the wheel slip is lowered. When a vehicle-body speed is smaller than a predetermined quick pressure reduction prohibiting speed, the ECU performs a quick pressure reduction prohibiting control to restrain a quick pressure reduction having a greater reduction amount than a predetermined reduction amount.
