摘要： An electric power steering device provides an appropriate power assist from the motor even when torque sensors have failed and the steering torque is no longer detected. If an error is detected in a torque sensor, the motor is driven based on the rotor rotation angle detected by a resolver and assist characteristics. When the absolute value of the rotor turning angle velocity calculated based on the rotor rotation angle falls to or below a prescribed value, a process is started for reducing the current driving the motor, and if the state in which the absolute value of the rotor turning angle velocity has fallen to or below the prescribed value continues over a prescribed length of time, the process for reducing the current is interrupted and, because an assist current was flowing at said time of interruption, an appropriate power assist can be given during a steering retention period.

摘要： Disclosed is an idle stop control device capable of relieving reaction force (kickback) of a handle occurring at idle stop controlled by the control of the idle stop control device. Specifically, an EPSECU (20) detects the rotational speed of an electric motor by detecting the rotational angle (θm) of the electric motor using a resolver (22), and at the same time, detects the steering torque using a torque sensor (23). Subsequently, the EPSECU determines whether or not the rotational speed of the electric motor and the steering torque are inside an idle stop transition area (P) by referring to a table (28) stored in a memory (27) in advance. When either or both of the rotational speed of the electric motor and the steering torque are outside the idle stop transition area (P), a signal requesting the prohibition of idle stop transition is output to an idle stop control device (10) via a cable (15). Upon receiving the signal requesting the prohibition of idle stop transition, the idle stop control device (10) prohibits the control of transition to idle stop even when conditions for idle stop are met.

摘要： An electric power steering apparatus detects, as an abnormal phase, a phase other than a combination of phases whose interphase voltage is of nearly zero volts if a q-axis current is equal to or smaller than a first threshold value though a q-axis voltage is being applied. Alternatively, the electric power steering apparatus calculates a base electric angle at which the q-axis current is equal to or smaller than a third threshold value though the q-axis voltage is being applied, and determines an abnormal phase based on the base electric angle.

摘要： Disclosed is an electric power steering device capable of applying a prescribed steering assist force to a steering assembly, even when a torque sensor is out of order and the electric power steering device is in a state of being unable to sense steering torque by the torque sensor. Using an angle of rotation of a rotating element, which is detected by a resolver that serves as a rotating element angle of rotation sensing unit of a motor, a steering angle and a steering angular velocity are estimated, and a prescribed steering assist force is applied to a steering assembly by the motor, on the basis of an estimated steering angle and/or an estimated steering angular velocity.

摘要： Control method for an electric power steering apparatus feeds back a motor current, flowing through a motor whose operation is controlled in accordance with a target motor current, so that the driving of the motor is controlled with the fed-back motor current. Peak value of the motor current is detected, and, for feedback control based on the detected peak value, the detected peak value is corrected to decrease. The thus-corrected peak value is fed back to control the motor current to conform to a target motor current value.

摘要： An electric power steering apparatus provides a steering assist of an electric motor directly to a vehicle steering system so as to reduce necessary steering power to be applied by a driver, and it is provided with a control unit including a phase compensation section implemented by software. The gain and phase of a steering torque signal from a steering torque sensor can be accurately set which correspond to the running and steering states of the vehicle, on the basis of a vehicle velocity signal from a vehicle velocity sensor. Thus, the gain in a high vehicle velocity condition and in such a frequency range outside the steering region can be controlled to substantially decrease so as to avoid parasitic oscillation and hence prevent the occurrence of magnetostrictive sound and hunting due to the parasitic oscillation. Accordingly, optimum steering feel can be achieved which corresponds to the states of the vehicle.

摘要： An electric power steering system is disclosed which includes an electric motor adapted to supply steering assist directly to the steering system to thereby reduce the steering torque to be exerted to the system by a driver. The steering system includes a phase compensative device which is formed of a phase delay circuit, or the phase delay circuit and a low-pass filter connected in series thereto, and is positioned in a loop connecting a motor current detector in the steering system and a drive controller in a control block, so that high-frequency components may be removed from motor current signals in the feedback loop. As a result, it is possible to suppress lag of the phases of the signals and hence to prevent parasitic oscillations, leading to the steering system being capable of providing steering assist most suited to particular steering operations and comfortable steering feel to a driver.
