摘要： An electric power steering system determines a steering state of a steering wheel on the basis of a current (Im) of a motor applying assist force to a steering system and a steering speed (ωs) of the steering wheel. A state where the steering wheel is retained at a position other than a neutral position is a retained state, and a state where the steering wheel is placed at the neutral position is a neutral state. When the steering speed (ωs) is lower than a determination value (ωa) and the motor current (Im) is larger than a reference value (Ix), it is determined whether the steering state is the neutral state. When the steering speed (ωs) is lower than the determination value (ωa), the motor current (Im) is larger than the reference value (Ix), and the steering state is determined to be the neutral state at immediately preceding determination, the steering state is determined to be the neutral state.

摘要： A vehicle steering apparatus in which a mechanical coupling between a steering member and steered wheels is uncoupled, includes a steering actuator for driving a steered mechanism and a control unit for drive-controlling the steering actuator. The control unit reduces steering-stiffness using a PID control portion for drive-controlling the steering actuator according to a deviation between a target steered angle and a steered-angle detected by the steered angle sensor. A gain setting portion sets gains of the PID control portion to be relatively low when a predetermined condition is satisfied.

摘要： A steering assist operation is performed, which includes a motor control unit that controls a motor, and the steering assist operation does not require a rotational angle sensor. A current drive unit drives the motor at an axis current value of a rotating coordinate system that rotates in accordance with a control angle, which is calculated by a control angle calculation unit. The control angle calculation unit obtains, at every predetermined calculation cycle, a present value of the control angle by adding an addition angle to an immediately preceding value of the control angle. An addition angle calculation unit calculates the addition angle to be added to the control angle through a proportional-integral control based on a torque deviation from a command torque set by a command torque setting unit.

摘要： An electric power steering system includes a motor that applies assist force to a steering system, and updates a motor resistance (Rm) that is a value indicating a resistance of the motor. Specifically, the motor resistance (Rm) is updated on the basis of the fact that an induced voltage (EX) of the motor is smaller than a first determination value (GA). In addition, when the induced voltage (EX) is smaller than or equal to a second determination value (GB), a divided value that is obtained by dividing a motor voltage (Vm) by a motor current (Im) is set as a new motor resistance (Rm).

摘要： A press-working apparatus capable of forming a clear character line. The press-working apparatus forms a product having a character line. The press-working apparatus comprises an upper die and a lower die arranged across a steel sheet, an upper die mechanism for moving the upper die toward and away from the lower die, a first holder and a second holder for clamping the steel sheet and applying an unwrinkling force to the same, and a control unit for controlling the upper die mechanism and the first holder. The upper die is divided on the character line of the product into a first upper die and a second upper die. The control unit makes the unwrinkling force by the first holder stronger than that by the second holder, so that the steel sheet is press-worked by the second upper die and then by the first upper die.

摘要： An automatic parking control is cancelled when a motor current has not yet reached a maximum current value Imax with a steering angle deviation exceeding a deviation threshold value. In addition, the automatic parking control is cancelled when a steering speed has not yet reached a maximum steering speed with a state where the motor current has reached and remains at the maximum steering speed continuing over a first time period. On the other hand, when a state where the steering speed has reached and remains at the maximum steering speed continues over a second time period, it is determined that there occurs an output shortage of a steering actuator, an automatic parking condition is recalculated, so as to allow the automatic parking continue to continue.
