摘要： A motor assisted steering apparatus has its wheels oriented with respect to a car body in response to a combination of a steering force which is supplied by a manual operation and a driving force developed by an electric motor which is energized in accordance with the steering force. The existence of an abnormality is annunciated when the relationship between the manual steering force and the operational condition of the motor deviates from a predetermined relationship. For example, the existence of an abnormality is annunciated when the motor is energized even though a steering wheel is not substantially operated, when the motor is energized for rotation in a direction which causes the wheels to be turned to the left even though the steering wheel is turned to the right or vice versa. The existence of such abnormality is detected by monitoring the manual steering force and the operational condition of the motor, without requiring any addition of sensors which have no direct connection with the operation of the apparatus.

摘要： A motor driven power steering apparatus includes a steering mechanism having a torque detector for detecting torque applied to the mechanism through a steering wheel. An electric motor is connected to the steering mechanism through an electromagnetic clutch. The current in the electric motor is monitored and if it becomes excessive, a control circuit is activated to deactivate the clutch. The electric motor is disconnected from the steering mechanism at the time the engine of the vehicle is starting and at other times during operation of the vehicle to determine if excess current flows through the motor which would be indicative of a malfunction of the electric motor.

摘要： A fail-safe arrangement for an electrical power steering system is directed to providing a control arrangement for a power steering motor which will prevent abnormal operation from having adverse impact. The control system detects the welding or sticking together of closed relay contacs and functions to prevent such a situation by monitoring the motor terminal voltage so as to cut off power above a predetermined value regardless of position of the relay contacts.

摘要： An active vibration insulator includes an electromagnetic actuator, a cyclic-control-signals output device, and an electromagnetic-actuator driver. The electromagnetic-actuator driver includes an asymmetric half-bridge circuit, and an actuating-signals output device. The actuating-signal output device outputs a signal for turning on one of a high-side switch and a low-side switch of the asymmetric half-bridge circuit, and outputs a pulse-width-modulated actuating signal for actuating the other one of them by means of pulse-width modulation based on the cyclic control signals, which the cyclic-control-signals output device outputs, or outputs a pulse-width-modulated actuating signal for actuating both of them by means of pulse-width modulation when the cyclic control signals are positive. Moreover, the actuating-signal output device outputs a signal for turning off one of them, and outputs a pulse-width-modulated actuating signal for actuating the other one of them by means of pulse-width modulation when the cyclic control signals are negative.

摘要： An active vibration insulator includes an electromagnetic actuator, a controller, and a bad-roads processor. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The controller carries out vibrating-forces generation control. In the vibrating-forces generation control, the electric-current supplies are made variable so as to actively inhibit vibrations generated by an on-vehicle vibration generating source of a vehicle from transmitting to a specific part of the vehicle based on cyclic pulsating signals output from the on-vehicle vibration generating source. Thus, the controller lets the electromagnetic actuator generate the vibrating forces. The bad-roads processor stops the vibrating-forces generation control effected by the controller when the vehicle travels on bad roads.

摘要： An active vibration insulator includes an electromagnetic actuator, a control-signals generator, a control-signals compensator, and a driver. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The control-signals generator generates control signals, which actively inhibit vibrations generated by a vibration generating source of a vehicle from transmitting to a specific part of the vehicle, based on cyclic pulsating signals output from the vibration generating source. The control-signals compensator compensates the cyclic control signals, which the control-signals generator generates, depending on output voltages of a battery. The driver is connected between the battery and the electromagnetic actuator, and makes the electric-current supplies variable based on the cyclic control signals, which the control-signals compensator has compensated, and the output voltages of the battery, thereby driving the electromagnetic actuator.
