摘要： In a motor control device (42) for a steer-by-wire steering device (10), the motor control device (42) having a redundant system consisting of two systems (L1, L2), a first turning current command value (It1) is calculated in a first system (L1), and a second turning current command value (It2) is calculated in a second system (L2). A third processor (68) outputs the first turning current command value (It1) when the two current command values (It1, It2) are not divergent and outputs the second turning current command value (It2) when the two current command values (It1, It2) are divergent. When a determination of a rapid steering operation is made, the third processor (68) outputs the first turning current command value (It1) regardless of whether or not the two current command values (It1, It2) are divergent.

摘要： A steering control device (1) includes a processor configured to execute a reaction force control process. The reaction force control process includes a reaction force torque calculation process of calculating a reaction force torque operation amount. The reaction force torque calculation process includes a deviation compensation calculation process of calculating a deviation-compensating component. The deviation compensation calculation process includes a process of calculating a positional deviation, a process of calculating the deviation-compensating component based on the positional deviation, and a process of switching among a plurality of calculation states for calculating the deviation-compensating component. The process of switching among the calculation states is a process of permitting switching among the calculation states on the condition that a permission condition is met. The permission condition is met based on an operation amount that varies in association with a driver's operation of an operation member.

摘要： A steering control device includes a processor. The processor is configured to execute a target rudder angle correction process, a restriction process, and a rudder angle control process. The target rudder angle correction process is a process of correcting the value of the target rudder angle variable by a play compensation amount corresponding to a steering direction. The restriction process is a process of restricting the magnitude of the play compensation amount to a small side depending on the traveling route at a current position of the vehicle and the traveling route at a movement-directional forward position. The rudder angle control process is a process of operating the motor (50) by a control in which a steering angle is adopted as a control amount and the value of the target rudder angle variable is adopted as a target value of the control amount.

摘要： A steering device includes a cylindrical support tube (17), a speed reducer (20), and a housing (18). The support tube (17) includes a flange (31), and supports a steering shaft (2) such that the steering shaft (2) is rotatable. The speed reducer (20) applies torque to the steering shaft (2). The housing (18) includes a cylindrical portion (41) that houses the speed reducer (20). The flange (31) and the cylindrical portion (41) are disposed coaxially, and coupled to each other by a bolt (30). The flange (31) and the cylindrical portion (41) include an engagement portion, at which the flange (31) and the cylindrical portion (41) are engaged with each other in a radial direction of the flange (31), at a different location from a location at which the bolt (30) is provided.

摘要： A steering device (10) includes a steering shaft (21), a motor (22), a stopper mechanism (40), and a controller (27). The controller (27) is configured to execute a first process and a second process when a determined condition is established. The first process includes causing the steering wheel (11) to operate to a first operation end through control of the motor (22) and thereafter operate in reverse to a second operation end. The second process includes computing a neutral position of the steering wheel (11) based on a rotational angle of the motor at a time when reverse operation of the steering wheel (11) is started and at a time when the reverse operation of the steering wheel (11) is ended.

摘要： A steering control system that controls a steering device (2) of a vehicle includes a storage unit, and a control unit configured to make a state transition to a normal control state via a start-up state after a power source system of the vehicle is started. In the start-up state, the control unit executes a correction information storing process of acquiring correction element information using a state variable obtained from the steering device (2) and writing correction information obtained based on the correction element information into the storage unit. In the start-up state, the control unit is configured to execute an abnormal condition determination process of determining whether an abnormal condition indicating that the correction information is abnormal is met. The correction information storing process is re-executed when the abnormal condition is met. The abnormal condition determination process is executed at least either before or after the correction information storing process.

摘要： A steering device turns a tire (99) of a vehicle of a steer-by-wire system (90) in which a steering mechanism and a turning mechanism are mechanically separated from each other and is provided with a turning device (80) including a turning actuator (88) and a turning angle control device (85). The turning actuator (88) turns tires (99) according to an instructed turning angle. The turning angle control device (85) calculates a turning angle command value (θ*t) corresponding to an inputted steering angle signal (θr) and generates a signal driving the turning actuator (88) based on that turning angle command value. The turning angle control device (85) applies limit such that the absolute value of a turning angle velocity becomes equal to or below a turning angle velocity limit value ωt-lim) set according to a predetermined parameter.
