摘要： PURPOSE:To improve controllability by setting a reference deceleration, based on a ratio between a pressure-decreasing control time and a pressure-increasing control time, so that, when a friction coefficient of a road surface varies during antiskid controlling, the variation can be detected at an early period of time. CONSTITUTION:In an antiskid controller, a hydraulic control valve device A is installed between a brake cylinder and a hydraulic pressure source for a wheel brake, and this device A is controlled by a controlling means B, based on at least one of reference values for controlling such as a reference wheel speed, a reference deceleration, a reference slip ratio, etc., in order to keep the wheel slip ratio at a suitable range. At least one of the reference values for controlling is determined by control-reference-value determining means C, according to a friction coefficient of the road surface. In this case, the control-reference-value determining means C is provided with a means, which determines at least one control-reference-value based on a relation of a time between decreasing and increasing of the hydraulic pressure of the brake cylinder for the pressure control, which is carried out successively by the hydraulic pressure control valve device A.

摘要： PURPOSE:To enable rapid cancellation of a lock tendency despite of a road surface state by a method wherein a 2-position solenoid valve device having a boosting position and a pressure reducing position is provided, and the solenoid valve device is repeatedly switched at intervals of a proper time to the boosting position and the pressure reducing position to provide a dwell mode. CONSTITUTION:In a device in which the wheel cylinders of front wheels on both sides and rear wheel on both sides are connected to the two pressurizing chambers of a tandem type master cylinder 10 through a piping, a 2-position valve 22 serving as a solenoid valve device is situated in the middle between liquid passages 18 and 20 through which a wheel cylinder 14 for the left front wheel is connected to the master cylinder 10. The 2-position valve 22 is formed such that it is switchable to a pressure reducing position allowing the liquid passage 20 to be communicated to a reservoir passage 26 through excitation. When a tendency to cancel the lock tendency of a wheel by means of a pressure reducing mode is produced, a mode in which the 2-position valve 22 is switched alternately to a boosting position and a pressure reducing position is executed. When the lock tendency is canceled through execution of the mode, shift to a slow boosting mode is executed and when not canceled, shift to a pressure reducing mode is effected.

摘要： PROBLEM TO BE SOLVED: To prevent unnecessary accelerated slip from being started by the simple noise while excessive smoothing of the wheel speed is not required. SOLUTION: The fraction control is permitted (S1), and all conditions to start the traction control are established (S3-6), and the driving wheel speed before smoothing by the filter processing is continuously increased three times to start the fraction control (S7-9). The driving wheel speed is not increased continuously three times before the smoothing due to the temporary rise by the single noise, and the fraction control is not started. A suitable filter means can be adopted to detect the single noise based on the driving wheel speed before the smoothing apart from the smoothing of the wheel speed due to the filter processing, and the unnecessary traction control due to the single noise can be excellently avoided.

摘要： PURPOSE:To enable detecting even the occurrence of liquid leakage to a reservoir by judging the occurrence of pump seizure on the basis of sharp or gradual drop of motor terminal voltage immediately after stopping the drive of a motor with the second drive means. CONSTITUTION:Upon detecting an abnormality, a pump motor C is first driven with the first drive means A for the first predetermined time. After stopping the drive operation of the motor, the judgement of an abnormality is made on the basis of a drop in the terminal voltage of the motor C. In other words, when the seizure of the pump B does not exist, a load on the motor C at the time of drive stopping, changes depending upon whether a liquid is leaking into a reservoir E or not. Consequently, when the terminal voltage sharply drops, it is judged that at least one of the pump seizure and liquid leakage to the reservoir is taking place. Then, the motor C is driven with the second drive means F for the second predetermined time long enough to pump out the whole amount of the leakage liquid. If the terminal voltage drop immediately after stopping the drive operation is sharp, the second judgement means G judges that the seizure of the pump B is existing.

摘要： PURPOSE:To prevent control accuracy from being degraded by correcting a set time in accordance with the optimum specified regulation at a specified time when the wheel tends to be locked while being in a quick pressure intensifying mode set by the previous unit control so that the control mode is completed before the set time. CONSTITUTION:A controller 50 operates the reference speed based on wheel speeds, wheel acceleration and estimated vehicle speeds from a revolution sensor 54, furthermore with anticipation of a specified slip rate for the estimated vehicle speeds, and then, judges whether or not anti-skid control is required when a brake pedal 12 is depressed. When the friction coefficient of road surfaces is abruptly decreased during the period of antiskid control, and when a quick pressure intensifying mode has been completed before a set time, which is caused by a two-position valve 22 of some certain unit control because of abrupt increase in brake actuating force, the set time for the following time is corrected in accordance with the specified regulation to a greater extent than being corrected in accordance with the normal regulation. By this constitution, the time until the set time for quick pressure intensification is corrected to the value suitable to the friction coefficient of road surfaces and brake actuating force, is shortened, degradation in control accuracy for wheel cylinder hydraulic pressure can thereby be prevented.

摘要： PURPOSE:To always obtain the optimum braking force regardless of road surface condition by controlling braking force by a function of sliding velocity when sliding velocity is increased, and controlling a control force by a function of sliding condition depending on sliding velocity and its change rate when sliding speed is decreased. CONSTITUTION:At the time of braking when a brake pedal 5 is stepped from wheel speed detected by a speed sensor 43. According to the wheel speed, an estimated car body speed is calculated, sliding speed is calculated by subtracting the wheel speed from the estimated car body speed, and further a change rate of the sliding velocity is found. When the sliding speed is increased, in the case where the sliding speed is within a designated range, braking force is controlled by a function of the sliding speed, and when the sliding speed is decreased, in the case where the sliding condition depending on the sliding speed and the above change rate is within a designated region, braking force is controlled by a function of the sliding condition.

摘要： PROBLEM TO BE SOLVED: To improve the reliability of determining the correction/error of detection in the accelerating slip state by ending the control according to the condition that the accelerating slip state at least starts to converge at the latest by a throttle valve device is closed to a control target opening after the traction control is started. SOLUTION: In the condition where a sub-throttle opening is larger than a main throttle opening and the wheel cylinder liquid pressure is zero, it is determined whether the driving wheel speed is a throttle valve control reference value or less or not. Thus, it is determined whether the situation where the accelerating slip state exceeds the preset accelerating slip state is detected by mistake or not. Sometimes the driving wheel speed is apparently or temporarily increased by the resonance of a driving system, electric noise of rotation sensors 74, 76 or the like so that the accelerating slip state exceeds the preset accelerating slip state. In this case, mis-detection flag is set and the throttle valve control and the brake control are ended midway.

摘要： PURPOSE:To obtain highly precise judgment on a degree of irregularity of a road surface through a device, in which the degree of the irregularity is judged from the number of times by which a wheel acceleration exceeds a standard acceleration during a preset period, by specifying a counting means, which counts the number of times by which the standard acceleration is exceeded. CONSTITUTION:In an antiskid controller, a hydraulic pressure controller A is installed between a brake cylinder and a hydraulic pressure source. In addition, an irregularity judging means B is provided, which counts the number of times by which the wheel acceleration exceeds a positive, standard acceleration during a preset period and, when the result of the count is greater than the preset count, judges that the irregularity of the road surface is large. Meanwhile, the hydraulic pressure controller A controls the hydraulic pressure in such a way that, when the irregularity of the road surface is judged to be large, the hydraulic pressure of a wheel cylinder is more increased, during an antiskid controlling period, than the case in which the irregularity is not judged to be large. In this case, a counting means, which is provided to the irregularity judging means B, should be a selective, counting means C, which conducts counting, excluding the case in which it is probable that the excess of wheel acceleration over the standard acceleration is due to the execution of a pressure decreasing mode.

摘要： PURPOSE:To enable rapid cancellation of a lock tendency despite of a road surface state by a method wherein a slow boosting gradient is controlled to a proper value through control of a continuous time ratio between a pressure reducing position or a dwell position and a boosting position so that a continuous time of a slow boosting mode is adjusted to a proper length. CONSTITUTION:In a device in which the wheel cylinders of front wheels on both sides and rear wheels on both sides are connected to the two pressurizing chambers of a tandem type master cylinder 10 through a piping, a 2-position valve 22 serving as a solenoid valve device is situated in the middle between liquid passages 18 and 20 through which a wheel cylinder of, for example, a left front wheel 14 is connected to the master cylinder 10. The 2-position valve 22 is switchable to a plurality of modes containing a pressure reducing mode and a slow boosting mode by means of a controller 50. In this case, when a continuous time of a preceding slow boosting mode is different from a target time, a ratio between a continuous time of a pressure reducing position or a dwell position in a present slow boosting mode and a continuous time of a boosting position is variable to a direction in which a continuous time of the slow boosting mode attains a value approximately similar to a target time.
