摘要： In a method of controlling an electric power steering apparatus by controlling a drive force of a steering force assisting electric motor when a vehicle speed is lower than a predetermined speed and controlling a braking force of the electric motor when the vehicle speed exceeds the predetermined speed, a steering wheel forward or reverse turning state is determined in accordance with a change in steering torque when the vehicle speed exceeds the predetermined state. The braking force of the electric motor is controlled only when the steering wheel reverse turning state is detected.

摘要： A load current control device operates so as to control the magnitude of a current delivered to a load by varying a duty factor. With this control device, a fundamental value is determined on the basis of an instruction of an input signal, and a reference duty factor and a reference current value are determined on the basis of the fundamental value. The control device further operates to correct the reference duty factor on the basis of a difference between the magnitude of a current actually flowing in the load and the reference current value to turn on and off a power supplied in accordance with the corrected duty factor, therby to control the magnitude of the load current. In addition, when the above-said difference is out of a predetermined range, this load current control device outputs a signal indicative of abnormal condition.

摘要： In an electro-mechanical converter of the type wherein a plunger contained in a cylinder is moved in the axial direction thereof by passing a control signal through a solenoid coil wound about the cylinder, the diameter of the plunger is made sufficiently smaller than the inner diameter of the cylinder such that the plunger can move without causing undue friction.

To control a power steering unit of a motor car a control valve is actuated by the plunger for controlling the amount or pressure of the operating oil supplied to the power steering unit, in which case the control signal is made to be proportional to the speed of the motor car.

摘要： A control device for a power steering apparatus includes a vehicle speed signal generator, a steering angle signal generating circuit, a first pattern memory, a second pattern memory, and a drive circuit. The vehicle speed signal generating circuit generates a vehicle speed signal corresponding to an actual vehicle speed. The steering angle signal generator detects a steering angle and generates a steering angle signal. The first pattern memory generates a power steering signal determined in correspondence with the vehicle speed signal. The second pattern memory generates a correction signal determined in correspondence with the vehicle speed signal and the steering angle signal representing a steering angle with respect to a neutral position of a steering wheel. The drive circuit outputs a correction result by correcting the power steering signal by the correction signal.

摘要： In a control device for a power steering apparatus of which steering force is controlled on the basis of a control signal produced in accordance with a vehicle speed signal, the control device comprises means which outputs an engine rotation speed signal corresponding to an engine rotation speed, change relaxation means for relaxing changes in the engine rotation speed signal, and a switchover circuit which outputs an output signal of the change relaxation means instead of the vehicle speed signal when the vehicle speed signal is lost. Accordingly, even if a vehicle speed sensor is out of order for any reason, the power steering is carried out by the engine rotation speed signal, resulting small change of the steering force. Thus, this can protect the vehicle driver from dangerous conditions.

摘要： An electrical energy stored in a capacitor is discharged to the solenoid of a solenoid pump through a thyristor as the latter is controlled to conduct, thereby producing a reciprocating movement of the piston of the pump. The value of the drive current passing through the solenoid is detected by a detection circuit, and a signal which depends on the magnitude of the drive current is applied to the trigger circuit of the thyristor. The period of oscillation of the trigger circuit which controls the conduction of the thyristor is controlled by the signal, whereby a uniform drive energy per unit time to the solenoid pump is assured.

摘要： A drive circuit for a solenoid pump comprises a series combination of a pump solenoid and a capacitor connected through a rectifier circuit with an a.c. source. The solenoid is shunted by another rectifier poled to pass a charging current to the capacitor. A thyristor is connected across the series combination, and is triggered into conduction, whereupon it short-circuits the series combination to permit a discharge of the capacitor through the solenoid and to prevent a current flow from the source to the capacitor, thus allowing a uniform control of the energy discharged by the capacitor. A trigger circuit for the thyristor comprises a relaxation oscillator including a programmable unijunction transistor, the conduction of which is controlled inversely to fluctuations in the source voltage.
