摘要： An electric power steering apparatus having a motor for producing assist torque according to the steering torque, and a rack and pinion mechanism for transferring torque assistance to the rack shaft. The pinion and rack of the rack and pinion mechanism are both helical gears, and transfer high torque to the rack shaft. The helical gears have a curved arc tooth profile. The teeth of a curved arc tooth profile gear set mesh with contact between convex and concave surfaces. The contact area is therefore increased and contact pressure is decreased compared with involute teeth. Surface fatigue strength, bending strength, and bending fatigue strength are thus greater compared with involute teeth. The combined steering torque and assist torque is efficiently transferred to the rack shaft, and durability is sufficient to withstand torque loads from motor inertia.

摘要： An automatic steering system for a vehicle is provided which includes a memory section for storing data for a steering angle of a wheel with respect to a distance of movement of a vehicle in correspondence to four parking modes. If a desired parking mode is selected by a mode selecting switch and the vehicle is moved at a creep while depressing a brake pedal, a control section controls the operation of a steering actuator to perform automatic parking control. At this time, an object detector continuously detects the position of an object around or in the vicinity of the subject vehicle, and when there is an obstacle already existing within a locus of movement of the subject vehicle, or when there is a possibility that a moving obstacle may enter into the locus of movement of the subject vehicle, a warning is provided to a driver, and an automatic brake is operated. Thus, it is possible to reliably perform the automatic parking control when there is an obstacle.

摘要： An electric power steering apparatus, which has an electric motor incorporated in a steering system to provide steering power assist directly to the steering system to thereby reduce manual steering effort required by the driver, includes a steering torque differentiating section arranged to output a differential value of a component of the steering torque which is free from a near-dc component and a high frequency component, a motor control signal determining section for subtracting a value corresponding to the steering velocity from a value corresponding the steering torque and adding the value corresponding to the steering torque to a value corresponding to the differential value to thereby determine a motor control signal, and a motor drive section for driving the electric motor on the basis of the motor control signal. With this arrangement, the electric power steering apparatus can improve the response characteristics of the steering power assist system while preventing undue increase in the gain of the control system at low frequencies in the range of 2 to 4 Hz, for example.

摘要： An electric power steering apparatus comprises a control unit for drive-controlling a motor to apply an assist torque to a steering system based on signals from various sensors. The control unit comprises a slip angle difference predicting section for predicting a difference between a slip angle of front wheels and a slip angle of rear wheels, and a correcting section for correcting, based on an angle difference signal outputted from the slip angle difference predicting section, a target torque signal supplied to the motor. Behavior of a vehicle is predicted from the angle difference signal and the target torque signal is corrected by a correction amount corresponding to the angle difference signal so that the motor can be drives controlled with the influence of a change in a road surface reaction force taken into consideration.

摘要： A steering system for a vehicle is provided in which each of the inner cables of two Bowden wires has one end thereof wound around and fixed to a driving pulley provided on a rotary shaft of a steering wheel, and the other end thereof is connected to a follower pulley. Spring sheets provided at end of outer tubes of the Bowden wires, are biased by springs and are connected to differential transformers. When a difference in tension corresponding to steering torque is generated between the two inner cables, the spring sheets are moved relative to each other, and a steering torque is determined based upon the amount of relative movement detected by the differential transformers. Thus, the steering torque inputted to the steering wheel can be correctly detected, while eliminating the influence of friction of the Bowden wires.
