摘要： A slip control system determines friction/slip characteristics of tires of a road vehicle equipped both with an antilock system to permit an individual brake pressure control on individual vehicle wheels. The front wheel brakes are connected to a primary output pressure space of the tandem master cylinder, and the rear wheel brakes are connected to a secondary output pressure space of the tandem master cylinder. A first bore stage of a housing of the tandem master cylinder forms a housing-defined boundary of the secondary output pressure space. An inner piston flange movably seals off a pressureless downstream chamber in relation to an inner portion of the first bore stage. An intermediate wall of the housing delimits the bore stage relative to a central bore stage which extends from a third bore stage receiving a primary piston. An actuating piston is displaceably guided in the central bore stage in a pressure tight manner and forms an axially movable, inner boundary of the primary output pressure space relative to a pressureless downstream chamber in the central bore stage which is bounded by the intermediate wall. An annular space is bounded in an axially movable manner by an inner piston flange of a secondary piston and by the intermediate wall and is connected to the pressure output of the controllable pressure source.

摘要： Improvements in vehicle antilock braking systems of the type having an operator controlled master cylinder (11) and a second source (55, 57) of pressurized hydraulic fluid for selectively supplying rebuild pressure after an antilock event are disclosed. The improved system is selectively operable in one of three braking modes, a normal braking mode (119) where braking force is proportional to an operator brake pedal pressure, an enhanced anti-skid braking mode (69) where braking force may be maintained at a maximum nonskid level, and a conventional anti-skid braking mode (71) where braking force follows a cyclic pattern of fluid pressure bleed and build. The system includes circuitry (17, 19, 35, 37, 93, 95) for determining the speed of each wheel and an arrangement (59) operable independently of any vehicle wheels for determining vehicle deceleration. This comparison normally invokes the enhanced anti-skid braking mode. In the enhanced mode, the system is continually searching for an optimum wheel speed reference (39) by determining (119) on which side of the peak of a mu-slip curve the vehicle is operating, for example, by calculating the sign of the slope of the mu-slip curve at the current vehicle operating point, and then incrementing (88) a prior wheel speed reference by a value (79) which changes the wheel speed reference toward the peak (75) of the mu-slip curve thereby calculating an updated wheel speed reference to control appropriately the braking system. The accuracy of the determined vehicle deceleration, and in particular, of the accelerometer is confirmed by comparison (63) to an expected deceleration based on operator brake pressure, and the conventional anti-skid braking mode is substituted for the enhanced anti-skid braking mode in the event the determined vehicle deceleration is determined to be inaccurate. The enhanced anti-skid mode utilizes a pulse width modulated solenoid actuated two position valve (41, 43) operable in one position to provide a fluid flow path from the braking device, and in the other position to provide a fluid flow path from a second source to the braking device.

摘要： A brake pressure controller, responsive to a wheel speed sensor and coupled to a brake, performs a cyclic control of pressure applied to the brake. A brake pressure cycle includes a pressure apply stage and a pressure dump stage having activation conditions based upon a slip threshold parameter. A predetermined base threshold quantity is modified in dependence upon a measured time duration of the pressure dump stage and/or a slip depth error quantity so that a greater amount of slip is added to the base slip threshold when braking on a deformable surface than when braking on a non-deformable surface.

摘要： An integrated control system for integrally controlling operations of an electronic torque split system and a traction control system for an automotive vehicle is provided. This system is such that when slippage of auxiliary driven wheels to which engine torque is variably delivered exceeds an auxiliary wheel target slippage value which is determined in a preselected relation to a cornering condition, the torque split system modifies an amount of engine torque distribution to the auxiliary wheels so that the auxiliary wheel slippage is adjusted toward the auxiliary wheel target slippage value, while the traction control system is activated to reduce an excess of engine torque constantly delivered to primary driven wheels for maintaining primary driven wheel slippage within a preselected allowable range.

摘要： In an electric control apparatus for a hydraulic brake control system of a vehicle, a feedback control portion is provided to produce a feedback control pulse signal indicative of a difference between a target slip ratio and an actual slip ratio. A feedforward control portion is provided to successively convert the target slip ratio in relation to a required braking force, a hydraulic braking pressure and an amount of hydraulic braking fluid, in sequence, and to convert the amount of hydraulic braking fluid into a feedforward control pulse signal. A pulse mixing circuit is connected to control portions to mix the control pulse signals for producing a mixed control pulse signal as a distinct control pulse signal. A driving circuit is connected to the pulse mixing circuit to control a hydraulic braking pressure applied to each wheel of the vehicle in accordance with the control pulse signal, regardless of the extent to which a brake pedal of the vehicle is depressed.

摘要： An anti-lock braking system (1) includes an electronic control unit or ECU having software which utilizes inputs of deceleration and pump motor voltage feedback to effect an appropriate duty cycle for the pump motor. By utilizing vehicle velocity, calculated vehicle deceleration and wheel deceleration to estimate the type of surface engaged by the vehicle wheels, and utilizing motor voltage to estimate pump load, the duty cycle of the motor may be varied so that low brake pedal effort braking has the benefit of less pump motor operation and reduced pump motor noise.

摘要： A circuit configuration for a brake system comprising an anti-locking control is furnished with circuits which: (1) at a low friction coefficient on either vehicle side, individually control the brake pressure on the rear wheel brakes upon commencement of a control process, (2) after the first entrance of a rear wheel into a stable phase switch to "select-low", and (3) in the select-low control phased if during a predetermined period of time no instability occurs on the non-selected rear wheel, increase the brake pressure on the non-selected wheel in the next pressure build-up phase by a fixed or variable amount. According to a first embodiment, the brake pressure is delivered prematurely into a wheel brake of the rear wheel if the wheel speed falls below a slip threshold if, at the same time, the factual reacceleration is above a threshold value and if another value derived from the maximum value of the filtered wheel acceleration is exceeded.

摘要： the present invention, a counter value is increased by a predetermined increment when it is judged that front wheel speed is being decelerated and speed difference between front and rear wheels is higher than a setting value, and the counter value is decreased by a predetermined decrement when it is judged that speed difference between front and rear wheels is not higher than the setting value. Next, if it is judged that the counter value is higher than the setting value, a high .mu. flag is set. If it is judged that the counter value is not higher than the setting value, the high .mu. flag is cleared. Thus, it is judged whether road surface has a high .mu. value or not by speed difference between front and rear wheels and by duration, during which the speed difference is maintained. When a high .mu. flag is set, a control value for high .mu. value is set as a control value relating to anti-skid brake control, and if the high .mu. flag is cleared, a control value for low .mu. value is set.
