摘要： A control unit estimates reverse transfer torque transferred from tires to a steering wheel and calculates an assist gain based on the reverse transfer torque. The control unit calculates basic assist torque demand by multiplying torsion torque detected by a torque sensor by the assist gain. The control unit further calculates assist torque command by adding compensation for stabilization. Since the assist gain is determined based on the reverse transfer torque, actual assist torque is generated in accordance with the force transferred from the road surface. Thus, a driver can operate the steering wheel while feeling the force from the road surface.

摘要： In an electric power steering system installed in a vehicle and designed to generate, by a motor, assist torque for assisting the driver's turning effort of the steering wheel, a self-aligning torque determiner determines a value of self aligning torque applied to the vehicle. A commanded-value generator determines a value of an assist ratio based on a predetermined relationship between a variable of the self aligning torque and a variable of the assist ratio. The assist ratio represents a ratio of share of torque by the motor for compensating the self aligning torque. The commanded-value generator generates, based on the self aligning torque and the value of the assist ratio, a commanded value for the assist torque. An assist torque determiner determines the assist torque based on the commanded value for the assist torque generated by the commanded-value generator.

摘要： In an electric power assisting system for a vehicle, a control unit receives an input shaft rotation angle detected by an input shaft rotation angle sensor and an output shaft rotation angle detected by an output shaft rotation angle sensor. The control unit controls rotation of a motor based on the detected two rotation angles. The control unit differently controls the rotation of the motor whether torque is applied from a steering wheel side or from a road surface side.

摘要： A vehicle integration control system includes a manager controller and a driving system controller. The manager controller sets a target generation driving force guide value for a driving force outputted from a driving system of a vehicle. The driving system controller controls the driving force on the basis of the target generation driving force guide value. The manager controller includes a driver request value setter and a driving force corrector. The driver request value setter sets a driver request generation driving force value corresponding to the driving force outputted from the driving system on the basis of a driver's input. The driving force corrector corrects the driver request generation driving force value on the basis of a predetermined program to restrain vibration generated in the vehicle when the driving force outputted from the driving system.

摘要： In a state where a driver sees a region near a vehicle, a finally-requested output-shaft torque is set so that a response is hastened in a deceleration and slowed in an acceleration. Thereby, a vehicle takes a forward descending position in which the front end of the vehicle is descending, which gives a driver a sense of deceleration or a sense of turning. Further, this position causes a front wheel load acting on the ground to increase and a rear wheel load acting on the ground to decrease, in comparison to a normal position. This thereby makes it easier for the vehicle to decelerate when practically decelerating or turning, and further enables turning to slightly over-steer. A resultant vehicular kinetic characteristic becomes comparable with a sense that is expected by the driver.

摘要： In a power steering apparatus employing an EPS (electrical power steering) motor coupled to a steering mechanism, when vibration of the steering mechanism is produced by twisting of tire rubber due to changes in steering angle, resultant pulsation of the drive current of the EPS motor are suppressed by adding to the drive current a current that is of equal frequency and opposite phase to the pulsation. Vibration of the EPS motor shaft, and resultant vibration of the steering wheel and vehicle body, are thereby effectively suppressed.
