摘要： An electromagnetic brake comprises a plurality of electromagnetic coils disposed on a stationary part of a drive force supply unit and producing a magnetic field in response to energizing currents supplied thereto, a rotor made of a conductive material and disposed on a rotary shaft of the drive force supply unit and positioned so as to rotate in the magnetic field and produce an eddy current in the rotor. The eddy current converts the rotational energy imparted to the rotor through the shaft into heat and generates a breaking force. A switching unit connected to the electromagnetic coils selectively controls the flow of energizing current to the coils in accordance with switching data supplied thereto by a control unit, responsive to external control data, for selectively controlling the ON/OFF ratio of energizing current flow to the electromagnetic coils.

摘要： An anti-skid control system for a motor vehicle, includes a brake fluid pressure buildup-control mode and a brake fluid pressure reduction mode, each of which occur cyclically. In each buildup-control mode, a control valve is repetitively opened and closed so that brake fluid pressure buildup and holding operations are performed alternately. The time period of each buildup-control mode is from a high peak of a wheel speed signal until a point of intersection between a reference velocity V.sub.W0 and the wheel speed V.sub.W. The reference velocity V.sub.W0 has an initial point Q positioned under the high peak V.sub.HP of the wheel speed V.sub.W by a velocity value .DELTA.V and extending straight at a gradient .theta.. The speed value .DELTA.V, the gradient .theta., and an initial pressure buildup time T.sub.P, in each building-control mode, are determined in accordance with the wheel acceleration in the preceding wheel acceleration, i.e., coefficient of friction of the road surface.

摘要： An anti-skid control system for motor vehicles is provided wherein the higher one of the lefthand and righthand rear wheels is selected as a first computed speed; the lower one of the above two wheel speeds is selected as a second computed speed; the lower one of the first computed speed and lefthand front wheel speed is selected as a third computed speed; the lower one of the first computed speed and righthand front wheel speed is selected as a fourth computed speed; and a reference speed is set up on the basis of the first computed speed in such a manner that it is lower than the first computed speed by a predetermined amount and follows the first computed speed with such a speed difference. Reduction of brake pressure which has been increased, is started on the basis of the third or fourth computed speed; and in the case where the second computed speed being decelerated, goes below the reference speed, the reduction of the brake hydraulic pressure is stopped at time when the second computed speed which is now being increased as the result of the brake pressure reduction goes above the reference speed, and thereupon buildup of the brake pressure is started.

摘要： A traction control method/apparatus for motor vehicles is arranged such that at an initial stage of the starting or accelerating operation of the motor vehicle where a large amount of slip of the driving wheel tends to be caused, a braking force is sufficiently applied to the driving wheel to restrain the slip thereof; and after the engine output is adjusted through accelerator or throttle control which is performed simultaneously with the application of the braking force, the procedure for controlling the brake hydraulic pressure is changed to eliminate the difference between the lefthand and righthand driving wheel speeds.

摘要： The present invention relates to a vehicle such as a forklift in which a hydraulic pump for driving the fork is driven by the same engine used to provide motive power to the vehicle. A inching control is provided in cases where an automatic transmission is employed for shifting the gears of the vehicle. The inching control controls the clutch to allow separate control of the motive system and cargo handling system of the vehicle. This control must be operated by an operator through the inching pedal. In the fork lift, the clutch plate wears excessively and therefore the relation between the amount of depressing of the inching pedal and engagement of clutch changes abruptly. The present invention discloses a technique to adequately measure the clutch position and for compensating for control of the clutch by always keeping constant the relation between the amount of depression of the inching pedal and the amount of engagement of the clutch.

摘要： An anti-skid control system for motor vehicles is disclosed wherein in case the wheel speed is equal to or lower than a minimum speed which is detectable by a microcomputer, the wheel speed is set at a predetermined threshold speed level between the minimum speed and zero, thereby preventing reduction of brake pressure from being started when the wheel is lower than the threshold speed. The anti-skid control system may also be designed such that a computed vehicle speed is set up which is approximate to the real vehicle speed; a reference speed is also set up on the basis of the computed vehicle speed in such a manner that it is lower by a predetermined amount than and follows the computed vehicle speed with such a speed difference; when the wheel speed becomes equal to or lower than a minimum speed which is detectable by a microcomputer, the wheel speed is set at a predetermined threshold speed level between the minimum speed and zero; and if a brake pressure reducing condition is prevailing at a point of time when the reference speed becomes equal to the threshold speed, then such a condition is released.

摘要： An anti-skid control system for a motor vehicle in which, when a wheel speed to be controlled and being decreased through buildup of brake pressure becomes equal to a reference speed, this equality is judged as a fulfillment of a brake pressure reduction starting condition, and thus reduction of the brake pressure is started. The highest wheel speed is detected and a computed vehicle speed is set up based on the highest wheel speed by having the increase and decrease of the highest wheel speed limited to a predetermined range. The computed vehicle speed and the wheel speed to be controlled are compared; and when the comparison indicates that the wheel speed to be controlled is equal to or higher than the computed vehicle speed, no reduction of the brake pressure is started irrespective of whether the brake pressure reduction starting condition is fulfilled.
