摘要： A steering control apparatus (6) for a steering system (1) includes a controller (41). The controller sets a limit value to less than or equal to a steering angle limit value, the limit value being an upper limit of an absolute value of a torque command value, and controls a motor such that a motor torque follows the torque command. When the absolute value of a rotation angle of a rotary shaft (11) exceeds a steering angle threshold, the controller computes a damping control amount such that the damping control amount increases with an increase in an excess of an angular velocity of the rotary shaft over a first upper limit angular velocity. The controller computes the torque command value based on a value obtained by combining the basic command value and the damping control amount such that an absolute value of the basic command value is reduced.

摘要： Provided is a steering control apparatus capable of reducing the occurrence of a situation in which power cannot appropriately be applied to a steering mechanism. A steering ECU includes a plurality of microcomputers configured to control driving of a motor so that an assist force is applied to a steering mechanism. A main communication line for communicating a main command value (ADAS1*) and a subsidiary communication line for communicating a subsidiary command value (ADAS2*) are connected to each of the microcomputers. The steering ECU includes a selection switching circuit (511) and an input value limiting circuit (512). The selection switching circuit (511) is configured such that its selection state is switchable to set use of the command value (ADAS1*, ADAS2*) communicated via any one of the communication lines for driving assistance control. When a selected command value (ADAS(N)*) obtained after the selection state of the selection switching circuit (511) is switched deviates from an allowable range, the input value limiting circuit (512) is configured to set use of a limiting command value (Rg*) for the driving assistance control in place of the selected command value (ADAS(N)*).

摘要： A steering control device (1) includes: an absolute steering angle detecting unit (53) configured to detect an absolute steering angle; and a current command value calculating unit (51) configured to calculate a current command value corresponding to a target value of the motor torque output from the motor (21). The current command value calculating unit (51) is configured to perform partial release control for decreasing a correction value of the current command value due to execution of the end contact relaxation control when a vehicle is tried to be turned at the time of execution of the end contact relaxation control. The current command value calculating unit (51) is configured to stop the partial release control when the current command value which is calculated at the time of execution of the partial release control is a value which is not affected by decreasing the correction value based on execution of the partial release control.

摘要： A steering control device (1) includes an electronic control unit. The electronic control unit is configured to perform end contact relaxation control for correcting a current command value such that a decrease of an end separation angle indicating a distance of an absolute steering angle from an end-position-corresponding angle is limited when the end separation angle is equal to or less than a predetermined angle and to perform partial release control for decreasing a correction value of the current command value due to execution of the end contact relaxation control based on a steering torque which is input to a steering system when a vehicle is intended to travel while turning at the time of execution of the end contact relaxation control.

摘要： A controller (20) for a motor (10) includes a first processing circuit (301) and a second processing circuit (302). The first processing circuit (301) is configured to execute a first operation amount calculation process, an operation process, and an output process. The first operation amount calculation process is a process of calculating a first operation amount. The operation process is a process of operating a first drive circuit (221). The second processing circuit (302) is configured to execute a second operation amount calculation process, a first use operation process, a second use operation process, and an initial value setting process. The second operation amount calculation process is a process of calculating a second operation amount. The initial value setting process is a process of setting an initial value of an integral element depending on a value of an integral element of the first operation amount calculation process.

摘要： A control steered angle calculation unit (53) includes: an end position determination unit (73) that determines whether a rack shaft is located at either one of right and left rack end positions; a motor absolute angle calculation unit (71) that detects a motor absolute angle (Θma); an end position-corresponding motor angle setting unit (74) that, when the rack shaft is determined to be located at either one of the right and left rack end positions, sets the detected motor absolute angle as an end position-corresponding motor angle corresponding to the one of the right and left rack end positions; and a control steered angle origin setting unit (75) that calculates an average value of right and left end position-corresponding motor angles as an offset angle, and sets an angle obtained by subtracting the offset angle from the detected motor absolute angle as an origin of the control steered angle represented by the motor absolute angle.
