摘要： An actual detected current value and a target voltage value of an electric motor are subjected to a low-pass filter process, and amounts of change per time in the filtered actual current value and the filtered target voltage value are calculated. If the amount of change in the actual current value on the increase side is greater than a criterion value and the amount of change in the target voltage value on the decrease side is greater than a criterion value, it is judged that the stroke end has been reached. Then, the upper limit value of the target current value is set at the actual current value obtained in the immediately previous cycle of the feedback control, so as to prevent generation of unnecessary torque.

摘要： A vehicle behavior control device (S) determines, by using a vehicle velocity (V), a transmission function (K(s)) which is determined based on a specification of the vehicle, receives as an input a wheel turning speed (ω) obtained by differentiating a wheel turning angle (δ) of left and right front wheels (FW1, FW2) with respect to time, and outputs a target yaw moment (My). The device (S) also calculates, by using the determined target yaw moment (My), a left-wheel-side forward/backward force (FxCL) imparted to a left wheel side (left front wheel FW1 and left rear wheel RW1) of a vehicle (10) and a right-wheel-side forward/backward force (FxCR) imparted to a right wheel side (right front wheel FW2 and right rear wheel RW2) of the vehicle (10). Then, the device (S) performs control to drive brake units (14-17) and in-wheel motors (IWMfl, IWMfr, IWMrl, IWMrr) depending on a turning direction of the vehicle (10), with the left-wheel-side forward/backward force (FxCL) serving as a braking force (or driving force) and the right-wheel-side forward/backward force (FxCR) serving as a driving force (or braking force). It is thus possible to ensure directional stability and responsiveness when the vehicle turns, taking into account a frequency response characteristic of a motion state amount generated on the vehicle (10).

摘要： When it is determined that a malfunction has occurred in a rotational angle sensor, an electronic control unit changes the control manner from the normal assist control to the sensorless assist control. In the sensorless assist control, an assist stop command unit receives the information concerning the motor rotational angular speed ωm from an angular speed conversion unit. Then, the motor rotational angular speed ωm is compared with the threshold value ωm1. If the motor rotational angular speed ωm is equal to or higher than the threshold value ωm1, an assist enabling signal is transmitted to a PWM voltage production unit to continue the power assist. On the other hand, if the motor rotational angular speed ωm is lower than the threshold value ωm1, a stop command signal is transmitted to the PWM voltage production unit to stop the power assist.

摘要： In a power supply apparatus 40, a power supply circuit is formed by a primary power supply circuit 50 which includes a high-voltage battery 51 and a step-down circuit 55 for stepping down the voltage of the high-voltage battery 51, and a secondary power supply circuit 60 which includes a low-voltage battery 61 and a step-up circuit 70 for stepping up the voltage of the low-voltage battery 61. The primary power supply circuit 50 and the secondary power supply circuit 60 are connected in parallel. An output voltage of the secondary power supply circuit 60 is set to be lower than an output voltage of the primary power supply circuit 50. When the output voltage of the primary power supply circuit 50 becomes lower than a target voltage of the secondary power supply circuit 60, the voltage stepped-up by the step-up circuit 70 is supplied to a motor drive circuit 32. Accordingly, power supply backup of an electric power steering apparatus can be performed as low cost.

摘要： The CPU calculates axial force matching external force that acts on a rack bar by combining steering torque MT that acts on a steering shaft with assist torque AT generated by an electric motor. The CUP then determines whether a vehicle is running straight based on a steering angle θ, a vehicle speed V, and the axial force F. Thus, even in a state where a control steering angle midpoint is deviated and a driver applies torque so as to return a turning position of a steering wheel to a neutral position, whether the vehicle is running straight can be accurately determined by making a determination by using the axial force F that acts on the rack bar. The CPU can set a considerably accurate control steering angle midpoint by calculating a smoothed steering angle midpoint by using an instantaneous steering angle midpoint in an accurately determined straight-running state.
