摘要： PURPOSE: To prevent the unncessary drive of a liquid pressure motor and prevent the waste of a battery by stopping the liquid pressure motor for recovering the brake liquid when the calculated output of the wheel speed becomes zero under a condition that no decompression control signal of the brake liquid pressure is outputted.
CONSTITUTION: While a car is traveling, the output of a wheel speed sensor 1 is converted into a pulse signal by a waveform shaping circuit 2 then inputted into a wheel speed arithmetic unit (AU) 3, and a wheel speed VW is calculated. When a brake action is taken under this condition, the wheel deceleration αW is calculated by a wheel acceleration/deceleration AU4. When it reaches the present deceleration, a slip ratio λ is calculated by a slip ratio AU6 based on a pseudo car speed V
i outputted from a pseudo car speed deciding unit 5 and the wheel speed VW, and an actuator 8 is switched and controlled based on this λ and the wheel deceleration αW. In addition, a decompression motor M is started by a decompression signal generated when the wheel speed VW becomes lower than a target value V
c . The motor M is stopped when no decompression signal is applied and the wheel speed VW becomes zero.

摘要： PURPOSE:To detect accelerated and decelerated speeds in all speed regions from low to high speeds with high accuracy in an arithmetic device for accelerated and decelerated speeds, which operates accelerated and delcerated speeds from the change in the periods of the output pulse of a speed sensor. CONSTITUTION:A titled device is so arranged that the number No for creating the pulse intervals to be calculated in order to execute the operations of accelerated and decelerated speeds without executing said operations until the intervals T1 of the pulses from a wheel speed sensor exceed the prescribed value T0 at which the operations of the accelerated and decelerated speeds are possible and that only when the pulse intervals exceed the value T0 the operations of the accelerated and decelerated speeds are executed. Thus when the intervals of the pulses generated by the wheel speed sensor in the storage of high speeds are extremely short, the pulse intervals are below the value T0; therefore the operations of the accelerated and decelerated speeds for each pulse are not executed and the operations of the accelerated and decelerated speeds are executed only when the number of the pulses giving the pulse intervals generating the periodic differences when the operations of the accelerated and decelerated speeds are possible exceeds the value T0. As a result, the arithmetic processing time for the accelerated and decelerated speeds in the stage of high speeds remain above the detected intervals of the pulses, whereby the errors in the operations of the accelerated and decelerated speeds by the reduction in the pulse intervals occurring in an increase in the speed are considerably reduced.

摘要： PURPOSE:To obtain maximum braking efficiency by making the most of each output of sensors stored according to fixed priority, in a captioned controller which makes an independent skid control for each wheel by making a time sharing process for each signal from a sensor provided on each wheel. CONSTITUTION:An antiskid controller is making a skid control by giving priority to a pulse first applied among pulses for wheel speed from sensors 1a-1d provided on each wheel while braking is being applied. In this case, an output from each of sensors 1a-1d is once stored in a memory 10. Process order is decided according to a predetermined priority in a priority decision part 12 through a pulse memory signal in the memory 10, and a pulse code signal corresponding to the pulse memory signal is made applicable. Each of the pulse code signals is applied in order to an operation processing part 16 and a memory resetting part 18 through a process pulse retainer 14, and an anti skid signal is generated at the operation processing part 16 through a fixed process.

摘要： PURPOSE:To avoid the delay in production of acceleration from being increased even at small car speed and small acceleration, by controlling the signal processing transfer pattern according to the specified period and periodic difference or more, through the comparison of the clock count values in the period according to the speed. CONSTITUTION:The latch circuit 3 is controlled with intermittent pulse according to the observed period in response to the car speed from the pulse controller 8, the clock count values in response to the car speed is sequentially stored in the memories 4a-4c of the memory controller 4, and the acceleration alpha is detected with the operation section at the operation comparison circuit 5. The comparison sections 5b, 5c of the circuit 5 compares respectively the output of the memories 4a-4c to control the controller 4 via the controller 7 when the observed period difference and observed period are more than a given value. Thus, the latch control of the circuit 3 via the controller 8 and the signal processing transfer pattern by the output control of the memories 4a-4c of the controller 4 are changed, allowing to extend the observing time of small speed and acceleration and to prevent the increase in the delay in the production of acceleration.

摘要： PURPOSE:To improve the safety of an antiskid controller by correcting the mode when the control mode deflects from a normal control cycle. CONSTITUTION:An antiskid control circuit 100 controls the switching between an inflow valve 14 and an effluence valve 15 on the basis of the signal outputted from a wheel-speed sensor 1 on brake application, and increases and reduces and retains the brake hydraulic pressure. When switching to the pressure increase is directly carried-out from pressure reduction without passing through the retention state, in the state where the wheel acceleration/deceleration speed determined in a high acceleration speed range is smaller than a certain value, pressure increase is prohibited, and the mode is corrected compulsorily to the retention or pressure reduction mode. Further, when the wheel acceleration/deceleration speed over the above-described certain value is obtained, the switching from pressure reduction to pressure increase is permitted.

摘要： PURPOSE:To prevent the formation of the no-brake state of an antiskid apparatus by switching a pseudo-car-speed to a calculated wheel-speed value when the calculated wheel-acceleration/deceleration speed recovers a certain deceleration speed lower than a set deceleration speed with which the pseudo-car-speed is generated. CONSTITUTION:When the deceleration speed below a set value is realized at a prescribed time, the slip rate lambda does not reach the slip rate lambda0 with which the brake efficiency becomes max. at that time, and a pressure increasing signal is outputted form an output signal determining part 7, and a detection signal is outputted from a deceleration-speed recovery detecting part 10. Therefore, a selecting switch 11 is switched to mode II, and a calculated wheel speed Vw is input in substitution for a pseudo-car-speed Vi into a slip-rate calculating part 6, and the output slip rate lambda supplied from the calculation part 6 is fixed at zero, and the output signal determining part 7 retains the output state for a pressure increasing signal, and a wheel is brake-applied by the hydraulic pressure ordinarily determined according to the amount of stepping-in a brake pedal.

摘要： PURPOSE:To eliminate the useless consumption of battery power source by suspending the operation of the hydraulic motor of an antiskid controller at early time after a car stops. CONSTITUTION:Each decompression signal is outputted indpendently according to the state of a right front wheel, left fron wheel, and rear wheels from control parts 3a-3c during antiskid control. A motor control part 5 outputs a driving signal on the basis of each decompression signal, and a hydraulic motor M continues operation. When the calculated wheel speed becomes zero after the lapse of a certain time shorter than a certain time during which the output of the signal for driving the hydraulic motor is continued, the hydraulic motor M is brought into stop.

摘要： PURPOSE:To improve safety of anti-skid control, by continuing anti-skid control of the control system by means of a signal from a normal wheel speed sensor when any abnormality is detected in either a wheel speed sensor for right front- wheel or a sensor for a left front-wheel, while giving an alarm for such abnormality of the wheel speed sensor. CONSTITUTION:If, during anti-skid control, a wheel speed sensor 1a for a right front-wheel becomes abnormal, a signal indicating such abnormality is generated from an abnormal sensor detecting unit 5, and inputted to a fail safe control unit 6. The fail safe control unit 6 outputs a switching signal to an input change- over switch 3a, while outputting to each of wheel control units 4a-4c an order to continue anti-skid control. The right front-wheel control unit 4a thereby outputs an anti-skid control signal on the basis of the detecting signal from the left wheel speed sensor 1b, while the other control units 4b and 4c output anti-skid control signals as usual. Upon completing the anti-skid control, the fail safe control unit 6 outputs a signal for increasing pressure as well as an alarming signal to activate an alarm unit 7.

摘要： PURPOSE:To make correction to an invariably correct wheel speed by detecting abnormality of a wheel speed on the basis of the difference between the current and preceding wheel speeds, and inhibiting the correction of the wheel speed according to the polarity of the variation value of the wheel speed. CONSTITUTION:Wheel speed pulse 2 is inputted to a wheel speed arithmetic part 31 to calculate a wheel speed. The current wheel speed is stored in the 1st wheel speed memory 34, and the preceding wheel speed is stored in the 2nd wheel speed memory 35. Those wheel speeds are inputted to a wheel speed variation value arithmetic part 36, and a changeover switch 39 for correction is switched from normal mode I to abnormal mode II by the output of a correction command part 41b when the difference between both wheel speed exceeds a prescribed value. Further, the polarity of the wheel speed variation value which exceeds the prescribed value is discriminated by a polarity discriminating part 41b, and correction is inhibited when the discriminated polarity is the same with the preceding variation value. A wheel speed is outputted from an output value memory 40 in abnormal mode.
