摘要： A device for controlling a motor-driven power steering system for a vehicle comprising: a torque sensor for detecting operator-induced steering force exerted on a steering wheel by an operator and generating a voltage signal representative thereof; a motor operatively connected to power assist the steering motion caused by the operator through the steering wheel; a control unit electrically connected with the torque sensor through a connector interposed therebetween for controlling the power-assisting operation of the motor in response to the operator-induced steering torque detected by the torque sensor; and a converter interposed between the torque sensor and the connector for converting the voltage signal generated by the torque sensor into a proportional current signal to be supplied to the control unit. With the above arrangement, the control unit is input with an electrical signal precisely representing the steering torque measured by the torque sensor without being affected by any voltage drop during transmission of the electrical signal from the torque sensor to the control unit, so that the control unit can control the power assisting operation of the motor in accordance with the measured steering torque in a most precise manner.

摘要： A power steering control apparatus for a car in which, under normal conditions, the steering becomes heavy as the speed of the car increases for the purpose of safety. This is realized by means of a hydraulic valve controlled by the reaction oil pressure of a proportional solenoid in the steering mechanism. In an abnormal condition such as the shortcircuit between solenoid coils or the failure of an electric control circuit, the conduction current of the proportional solenoid is interrupted by the electric control circuit whereby the reaction oil pressure is increased to cause the steering to become heavy. This function is performed by a failsafe circuit in the electric control circuit which monitors the error between the car speed inverse proportional signal and a feedback signal from the solenoid and then holds the abnormal condition when the error exceeds a predetermined value.

摘要： A power steering control apparatus for a car in which, under normal conditions, the steering becomes heavy as the speed of the car increases for the purpose of safety. This is realized by means of a hydraulic valve controlled by the reaction oil pressure of a proportional solenoid in the steering mechanism. In an abnormal condition such as the shortcircuit between solenoid coils or the failure of an electric control circuit, the proportional solenoid is deenergized through a failsafe circuit due to the fact that a feedback signal from the solenoid has become zero and the error with a high amplification gain between the car speed inverse proportional signal and the feedback signal has exceeded a first predetermined value. On the occasion of the voltage reduction of the power source for the electric control circuit and/or the increased temperature of the proportional solenoid, the failsafe circuit is disabled by an error protection circuit only when the difference between the car speed inverse proportional signal and the reduced feedback signal exceeds a second predetermined value.

摘要： A control unit is disclosed for controlling the driving torque of a generator driven by an engine in accordance with the number of cylinders to be operated, thereby to achieve stabilized operation. A voltage regulator is provided for varying the field current through the field coil of the generator so as to regulate the output of the generator. A circuit component including a pair of NC contacts in parallel with a resistor is connected in series between the field coil of the generator and a power source. Depending on the number of cylinders to be operated, the NC contacts are either closed to provide a low resistance path for current to the field coil or are opened to provide a high resistance path through the resistor.

摘要： An electric power steering device is disclosed which comprises a fail-safe relay. The circuitry for operating the relay comprises the following: the neutral region detector circuit which generates an output when the steering torque applied by the operator is in the neutral region; a motor current detector circuit for detecting the motor current; an AND gate having inputs coupled to the above two circuits; a self-hold circuit for holding the output of the AND gate; and a relay interrupting circuit for interrupting the relay in response to the output of the self-hold circuit. Thus, the fail-safe relay is interrupted to disconnect the battery from the motor and clutch when the motor is energized in spite of the fact that the steering torque by the operator of the vehicle is in the neutral region.

摘要： An electric power steering apparatus for an automotive vehicle has an interrupter which cuts off the power to a drive motor when a dangerous situation is detected. In one form of the invention, the interrupter cuts off power to the drive motor when a ground fault sensor detects a ground fault of a motor driver and there is disagreement between a directional drive signal to the drive motor and the direction of torque applied to the steering wheel by the driver. In another form of the invention, the interrupter circuit cuts off power when the vehicle speed exceeds a prescribed level and the torque applied to the steering wheel exceeds a prescribed level for a certain length of time. In a third form of the invention, the interrupter cuts off power when the motor current exceeds a prescribed level and disagreement of directional signals is detected.

摘要： An electric power steering device having a clutch 25 for connecting and disconnecting the motor 14 to and from the steering shaft is disclosed, the control circuit of which comprises, in addition to a microcomputer 3, an additional analog direction determiner circuit 17, and a first and a second logical circuit. The first logical circuit consists of a pair of AND gates 20A, 20B generates a final right or left direction signal supplied to the motor driver circuit. The second logical circuit consists of a pair of exclusive OR gates 21A, 21B and an AND gate 22 and supplies a deenergization signal to the clutch driver when the directions determined by the microcomputer and the analog direction determiner circuit disagree. The direction determiner circuit includes: a first comparator 31 which outputs a right direction signal when the output voltage of the torque sensor exceeds a first reference level; and a second comparator 32 which outputs a left direction signal when the output voltage of the torque sensor is below a second reference level which is lower than the first level. These reference voltages, selected at upper and lower ends of the non-sensitive region, may be obtained by a voltage divider.
