摘要： To provide optimal braking force control using braking operation data, an ECU in a brake force control system detects a braking operation according to fluctuation components of wheel rotation. That is, the ECU calculates the wheel acceleration and sets a reference load level for the braking operation according to a road surface coefficient of friction at the wheel tire. When the amplitude of the wheel acceleration increases and exceeds the reference load level, the braking load is determined to be heavy. If the braking load is heavy, the ECU decreases the brake oil pressure of the wheel being detected. In this way, the slip ratio can be controlled around a peak road surface coefficient of friction.
摘要翻译：为了使用制动操作数据提供最佳制动力控制，制动力控制系统中的ECU根据车轮旋转的波动分量来检测制动操作。也就是说，ECU计算车轮加速度，并根据车轮轮胎的路面摩擦系数设定制动操作的基准负载水平。当车轮加速度的振幅增加并超过参考负载水平时，制动负载被确定为很重。如果制动负载较重，ECU会降低被检测车轮的制动油压。以这种方式，可以围绕峰值路面摩擦系数控制滑移率。

摘要： In order to achieve an optimal pressure build-up function in an anti-lock braking control system for automotive vehicles and to maintain the pressure at the optimal point for long periods of time and thus achieve better brake deceleration with greater stability of travel and greater comfort than with conventional ABS control systems, the anti-lock braking control system includes, in addition to the ABS controller and monitoring circuit (3), a pressure function generator (4) which, for each wheel, intermediately stores an intermediate brake pressure value whenever wheel overbraking has been noted. Then, in the pressure build-up phase, the pressure function generator (4) gives off a signal to the pressure modulator in order to increase the wheel brake pressure in accordance with an exponential function.

摘要： An anti-lock braking method to retard the wheels of a vehicle provides thatbrake pressure be augmented or reduced or maintained constant in response to slip and/or the change in the rotational speed (positive or negative deceleration) of a retarded wheel as related to at least one threshold value, andthe respective renewed accelerations of the retarded wheels be measured during successive control cycles of the anti-lock braking so as to raise the threshold value or prevent a reduction of the brake pressure for a predetermined period of time in order to suppress undesired control operations which are releasable above all by oscillations of the vehicle axle. To avoid interference of the ABS control by axle oscillations, it is provided thata raised threshold value is maintained for a given period of time and then lowered once more to the basic value if no wheel retardation is measured and the threshold value is not exceeded either during this given period of time, the given period of time being somewhat longer than one axle oscillation period of a vehicle axle, whereasin the event that the threshold value is failed to be reached within the given period of time, this will not initiate a reduction of the brake pressure of the wheel, and a period of time will be measured during which the threshold value remains to be fallen short of, andin the event that this measured period of time is shorter than a predetermined period of time, reduction of the brake pressure continues to be precluded for an additional period of time which is at least as long as one typical axle oscillation period of the vehicle axle.

摘要： A system for correcting a wheel speed data produced by a wheel speed sensor, employs a filter for removing noise contained in the output of the wheel speed sensor. The filter limits variation rate of the wheel speed data so as to avoid occurrence of extraordinary variation of wheel speed as influenced by error factors, such as destruction of the wheel speed sensor or noise superimposed on the output of the wheel speed sensor.

摘要： According to the present invention, the time during which the hydraulic braking pressure is intermittently maintained, is varied depending upon the degree of decrease in the wheel speed relative to the vehicle speed, so that the time may be prolonged when a large decrease occurs. Hence, unnecessary maintenance of the intermittent maintaining time is avoided in order to prevent any unnecessary operational noise from being produced.

摘要： A schedule of brake pressure ramp rates is provided in a vehicle antilock brake controller as a function of predetermined wheel parameters. The ramp rates associated with the specific values of the wheel parameters are filtered by limiting the changes in ramp rate to a next higher ramp rate from the schedule of rates when the ramp rate called for by the wheel parameters is greater than the present ramp rate and to a next lower ramp rate from the schedule of rates when the ramp rate called for by the wheel parameters is less than the present ramp rate.
