An electric power steering apparatus provides a steering power assist of a motor to the steering system of an associated automotive vehicle, so as to reduce necessary steering power to be applied by a driver. The steering apparatus includes an attenuation device in the form of a phase delay circuit or an active low-pass filter, which is provided in a feedback loop connecting a motor current detector and a control section of a control unit constituting the vehicle steering system. By the attenuation device attenuating relatively high frequency components of motor current detected by the motor current detector, there is achieved a high-performance electric power steering apparatus which is capable of reducing noise in the feedback loop, without affecting the motor current, to a sufficient degree to highly improve a response to a driver's steering operation.

An electric mirror control device provided with a proportionality constant conversion means for converting the proportionality constant of a detection output voltage to the angle of a mirror surface to be positive or negative. When an up-down sensor and a right-left sensor for detecting the angle of the mirror surface have a plurality of specifications, each of which has a different proportionality constant of the detection output voltage to the angle of the mirror surface, controller determines the specification of the angle sensors based on whether the proportionality constant of the detection output voltage output via the proportionality constant conversion means is positive or negative, and controls an up-down motor or a right-left motor in accordance with the determined specification stored in advance.

An outer sliding sunroof apparatus having a roof panel attached to an opening of a fixed roof of a vehicle, a drive device for opening and closing the roof panel, and a control unit for controlling the drive device. The apparatus further includes a load detector for detecting load applied to the drive device when the roof panel in a closed state is tilted up and moved toward a rear of the vehicle. When the load detector detects the load not less than a predetermined amount of load, the control unit is configured to move the roof panel in the closing direction.

An electrically operated mirror control device comprises a controller which includes a reverse linking unit for carrying out a reverse linking operation to tilt a mirror to change a mirror surface angle in linking with reversing of a vehicle, and a mirror switch which adjusts an amount of a change in the mirror surface angle of the mirror in the reverse linking operation. When the controller detects a predetermined operation in the reverse linking operation, a reverse angle memorizing control unit changes a first setting stored in a memorizing unit into a second setting of the mirror surface angle including the amount of the change in the mirror surface angle adjusted by the mirror switch at an end of the reverse linking operation.

A system of controlling a sliding member for a vehicle includes a motor, a pulse generating device, a counting device and a control device. The system has a range for movement of the sliding member between a position short of a first lock position and a position short of a second lock position. Also, the system has an error range within the range for movement of the sliding member and memorizes in advance a range of pulse count representative of the error range. If a pulse count counted by the counting device falls within the range of pulse count when the sliding member discontinues movement due to detection of an overload of the motor, the system resets a pulse count counted by the counting device at one of the first and second lock positions.

摘要:
In a vehicle suspension system including a hydraulic actuator between a sprung mass consisting substantially of a vehicle body and an unsprung mass consisting substantially of a wheel, a force proportional to but opposite in phase to an inertia force acting on the unsprung mass is applied by the actuator to the unsprung mass so that the ability of the tire to maintain contact with the road surface may be improved. This produces very little effect on the behavior of the sprung mass, but the vehicle handling is significantly improved. Better contact with the road surface not only improves the vehicle handling but also reduces the consumption of energy by the hydraulic actuator. A particularly favorable result can be obtained when the hydraulic actuator further applies a damping force proportional to the absolute velocity of the sprung mass to the sprung mass.

In an active vehicle suspension system employing a spring and a hydraulic actuator for supporting a wheel relative to a vehicle body, a control unit actuates the actuator so as to cancel the force applied by the spring force of the spring and a damping force applied by the hydraulic actuator. This damping force is typically produced by the flow resistance which the hydraulic oil encounters in the hydraulic circuit. This control action is carried out according to a signal obtained by processing an output of a displacement sensor between the wheel and the vehicle body with a first-order lead filter circuit. Thus, the control action is based on a readily available and highly responsive detection signal, an accurate and stable vibration control of the sprung mass of the vehicle or the vehicle body is made possible. This control action may be combined with a conventional feedback control based on the acceleration of the sprung mass or the load acting between the suspension system and the vehicle body, and a low-pass filter which ensures the stability of the system even when the first-order lead filter circuit is used.
