摘要： An antiskid control system is disclosed in which a single solenoid-operated switching valve connects a single wheel brake selectively to a high pressure or low pressure from a source of brake pressure. After the decompression of a wheel brake pressure, a repetitive intensifying operation is executed with a period of 40 msec in which an intensifying and a decompressing operation take place alternately. During the repetitive intensifying operation, the duty cycle for the intensifying operation is increased at a given rate. A flash intensification is executed immediately before the repetitive intensification. An initial value of the duty cycle for the repetitive intensification which occurs after the decompression of a second and a subsequent pass is chosen in proportion to the time duration of the previous repetitive intensifying operation and in inverse proportion to the immediately preceding decompressing interval.

摘要： A rod actuator which includes a d.c. motor, a reduction gearing, a solenoid assembly which is used to define an intermediate stop position, and rotation stops. The angular extent through which an output shaft of the reduction gearing is rotatable is limited by a pair of limit stops. The solenoid assembly includes a plunger which is located intermediate the limit stops. A rotational stop is rotatably mounted on the output shaft and has a projection which is adapted to abut against the plunger to cease the motion of the rotational stop. The rotational stop is mounted on the output shaft so as to be rotatable relative thereto through a small angle by a lost motion, but is driven for integral rotation with the output shaft when such angle is exceeded. A lost motion connector is used so the angles of rotation where the rotation of the output shaft is stopped by the plunger during its clockwise and counter-clockwise rotations will be substantially equal. The actuator may be used in a shock absorber mounted on a vehicle to establish three levels, "high", "medium" and "low", of attenuation exhibited by the shock absorber.

摘要： A mover such as a vehicle acquires the information, which has been updated by broadcasting/communication during an engine stall or in an unreceivable state, after the engine start or the recovery of reception. The engine stall period and the unreceivable state continuation period of the mover are monitored and are notified after the engine start from a communication device to an information center and a mounted device. In response to this notification, the information center extracts the information, which has been updated during the engine stall period and the unreceivable state continuation period, and transmits the information to the communication device of the mover. As a result, the mover can always hold the latest information of a broadcast receiving device, the communication device and an information service device.

摘要： A wheel slipping control apparatus for controlling a braking hydraulic pressure to be applied to a wheel so as to perform an effective braking operation. The wheel slipping control apparatus comprises a control unit for generating a control signal in accordance with the wheel slipping state so as to perform a braking pressure control cycle so that the braking hydraulic pressure is set to a pressure decreasing mode and then to a pressure increasing mode. In the control unit, one of the braking pressure control cycles to be performed is determined as a learning control cycle to obtain a learning pressure-decreased value decremented in the learning control cycle and to obtain a learning pressure-increased value incremented in the learning control cycle. A present pressure-decreased value decremented in a control cycle after the learning control cycle is obtained to calculate a target pressure-increased value on the basis of the obtained learning pressure-decreased value and learning pressure-increased value whereby the braking hydraulic pressure is first increased to the vicinity of a wheel locking limit pressure after decreased in the pressure-decreasing mode.

摘要： In an apparatus for detecting the abnormality of a rotational speed sensor adapted for, for example, an anti-skid control system, a time period within which a subsequent pulse will be generated by the rotational speed sensor in response to the rotation of a body of revolution such as wheel is estimated on the basis of the latest pulse interval of the pulses previously generated therefrom and a value corresponding to the force of inertia of the wheel developed on the braking operation thereof. The determination of abnormality of the rotational speed sensor is made when the subsequent pulse is not produced within the estimated time period. This is arranged based on the fact that the pulse interval depends upon the inertial force of the wheel. With the above arrangement, the abnormality detection of the speed sensor can be quickly made, so that a fail-safe control in a braking system can be speedily performed in response to the occurrence of abnormality of the speed sensor.

摘要： In an antiskid control system for the hydraulic braking system of a wheeled vehicle, the rotational speed of a vehicle wheel and the acceleration of the wheel are detected and levels of road surface friction are determined on the basis of the wheel speed and acceleration to give a first indication that the road has a high value of friction or a second indication that the road has a low value of friction. The wheel speed and acceleration are analyzed to detect a down-pressure mode to decrease the fluid pressure of the braking system and an up-pressure mode to increase the pressure. In response to the presence of the first indication, the down-pressure mode is effected at a lower rate and then at a higher rate. In response to the occurrence of the second indication, the down-pressure mode is effected at the higher rate.

摘要： In an antiskid control system the speed of a vehicle wheel is compared with a variable threshold which is a function of the speed of the vehicle and a first comparator output is generated when the speed is lower than the variable reference. The acceleration of the wheel is compared with a predetermined threshold for generating a second comparator output when the acceleration is lower than the threshold or a third comparator output when the acceleration is higher than the threshold. The fluid pressure of the braking system is lowered in response to there being a simultaneous presence of the first and second comparator outputs and raised in response to there being a simultaneous presence of the first and third comparator outputs.
