摘要： An apparatus for preventing a vehicle from deviating from the correct locus of movement thereof when the vehicle travels in a direction opposite to the direction designated by a gear selecting lever during an automatic parking control operation. When automatic parking control operation is started, the wheels are automatically steered on the basis of the relation between the traveling distance of the vehicle and a standard steering angle which is stored in advance in a storage device, and the vehicle is guided automatically to a parking position. When the vehicle, for which the automatic parking control operation has been started from a position O, moves back from a position Q due to the inclination of the road surface, the automatic parking control operation necessarily continues to be carried out unless the forward movement or backward movement of the vehicle is recognized and the vehicle travels to a different position O'. When the forward or backward movements of the vehicle is recognized, and when the vehicle moves back from the position Q, the standard steering angle .theta.ref is reproduced reversely from the position Q and outputted, whereby the vehicle can be returned to the original position O.

摘要： A valve operating system for an internal combustion engine includes a valve-opening electromagnet and a valve-closing electromagnet for exhibiting an electromagnetic force for attracting an armature to operate an engine valve, and a valve-opening resilient means and a valve-closing resilient means for maintaining the armature at a predetermined neutral position during deenergization of the electromagnets. In each electromagnet, a coil is inserted between inner and outer yokes which are disposed in the form of a double-cylinder such that they open at their ends opposed to the armature and are magnetically coupled to each other at their ends opposite from the armature, and the coil is positioned so that the coil protrudes from at least one of the yokes toward the armature. The armature has an annular accommodating portion provided in a surface thereof opposed to each the electromagnets and capable of accommodating that portion of the coil which protrudes from the yoke. With such a structure, it is possible to increase the electromagnetic attracting force of each of the electromagnets and to enhance the performance of the engine.

摘要： The elimination of a steering angle detector from an automatic steering system including an electric motor used as an actuator is accomplished and the steering angle of a wheel is calculated based on the rotational angle of the electric motor. In the electric motor, if a terminal voltage is represented by u; a supplied current is j; a resistance is R; an inductance is L; a rotational angle is .alpha.; and a constant depending on characteristic of the electric motor is K, the terminal voltage u is represented by the following equations: ##EQU1## If this equation is solved with respect to the rotational angle .alpha. and the inductance L having a small value is omitted, the rotational angle .alpha. is given according to the following equation: ##EQU2## The rotational angle .alpha. of the electric motor and the steering angle of the wheel are in a proportional relationship to each other and hence, if the rotational angle .alpha. is calculated from the terminal voltage u and the supplied current j to the electric motor, the steering angle of the wheel can be found. Thus, a steering angle detector can be eliminated.

摘要： A cable-type steering device for controlling operation of a power-steering motor in accordance with the tension on stranded metal wire cables which connect a vehicle steering wheel to a steering gearbox. Tensions of the cables are detected by contact with an arm of a potentiometer. The surfaces of the cables are smoothed by a swaging treatment or resin coating treatment to prevent undesirable vibrations of the arm of the potentiometer and improve the detection accuracy of the potentiometer. The smoothing treatment eliminates undesirable vibration which might otherwise occur due to irregularity of the surface of untreated stranded metal wire cable.

摘要： A steering apparatus steers a steerable road wheel in response to turning movement of a steering wheel with a variable steering angle ratio therebetween. The steering apparatus includes a first member operatively coupled to either one of the steerable road wheel and the steering wheel, and a second member operatively coupled to the other of the steerable road wheel and the steering wheel. The first member has a portion engaging the second member at a variable engaging position that is movable on a predetermined path. The steering angle ratio varies when the engaging position varies. When the steering angle ratio varies with the first and second members in their respective neutral positions, the first and second members remain completely still, and their neutral positions are kept in alignment with each other.

摘要： A steering apparatus has a sector shaft rotatable in response to rotation of a steering wheel for steering road wheels through a pitman arm coupled to the sector shaft. A torque sensor for detecting a steering torque applied to the steering wheel is positioned closer to the steering wheel than the sector shaft in a path of the steering torque from the steering wheel to the sector shaft. An electric motor is operatively coupled to the sector shaft for applying an assistive force to the sector shaft. The electric motor is controlled by a controller based on an output signal from the torque sensor. A steering angle ratio varying mechanism is disposed between the sector shaft and the torque sensor for varying the ratio of an angle through which the road wheels are turned to an angle through which the steering wheel is turned.
