STEERING DEVICE

A steering device includes a steering shaft, a motor, a stopper mechanism, and a controller. The controller 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 to operate to a first operation end through control of the motor and thereafter operate in reverse to a second operation end. The second process includes computing a neutral position of the steering wheel based on a rotational angle of the motor at a time when reverse operation of the steering wheel is started and at a time when the reverse operation of the steering wheel is ended.

STEERING SYSTEM

A steering system includes a steering operation shaft in which power transmission to and from a steering wheel is disabled and that steers a steered wheel of a vehicle, a steering operation motor that generates a steering operation force that is a torque applied to the steering operation shaft so as to steer the steered wheel, and a control device that controls the steering operation motor. When a rotation position of the steering wheel is different from a rotation position corresponding to a steered position of the steered wheel, the control device executes a process for correcting the steered position of the steered wheel to a position corresponding to the rotation position of the steering wheel through the steering operation motor.

STEERING SYSTEM

A steering system includes a steering shaft that rotates along with an operation of a steering wheel; a motor configured to generate a torque that is applied to the steering shaft; and a control unit configured to control the motor. The control unit is configured to control the motor such that a rotation speed of the steering wheel decreases gradually to zero when automatic rotation of the steering wheel is stopped, in a case where the steering wheel is automatically rotated as an adjustment process of adjusting a rotational position of the steering wheel.

STEERING SYSTEM

A steering system includes a steering shaft; a motor configured to generate a torque applied to the steering shaft; and a control unit configured to control the motor. The control unit has a function of performing steering angle feedback control for causing a steering angle that is a rotation angle of a steering wheel to reach a target steering angle that is set based on a point of view of adjusting a rotational position of the steering wheel, as an adjustment process of adjusting the rotational position of the steering wheel. The control unit is configured to set a limit value for limiting a change range of the target steering angle with respect to the steering angle at each moment in a period in which automatic rotation of the steering wheel is hindered in a case where the automatic rotation is hindered while the adjustment process is being performed.

STEERING SYSTEM

A steering system includes a steering shaft; a reaction motor; and a control unit configured to control the reaction motor. The control unit has a function of performing a correction process of rotating the steering wheel using the reaction motor such that a displacement in a rotational position of the steering wheel with respect to a correct rotational position corresponding to a turning position of the turning wheels decreases when a power supply of the vehicle is turned on and the rotational position of the steering wheel is different from the correct rotational position. The control unit is configured to perform the correction process when the displacement is equal to or greater than a predetermined permissible value and not to perform the correction process when the displacement is less than the permissible value.

Steer by wire rotational travel stop

Controlling a steer-by-wire steering system

A vehicle steering system includes a steering actuator which acts on steered wheels, an actuation unit, a feedback actuator to which a user request for a steering angle can be applied using a steering input means, which outputs a feedback signal to the steering input means in response to the request and a driving state of the vehicle. A signal transmission transfers the request to the actuation unit. The actuation unit actuates the steering actuator to deflect the wheels. When a monitor detects a malfunction of the feedback actuator as a fault situation, the feedback signal and the signal transmission is modified or generated according to multiple options.

Steering column for a motor vehicle

A steering column for a steer-by-wire steering system include a steering shaft that is connectable to a steering wheel and is received in an inner steering column tube such that the steering shaft is rotatable about a longitudinal axis. An outer steering column tube may receive the inner tube such that the inner tube can be displaced along the longitudinal axis. The outer tube may be connectable to a vehicle chassis. The steering column may also include a feedback actuator having an electric motor that drives the steering shaft via a drive component that is connected to the steering shaft for the transmission of torque. The drive component may have a recess with a maximum inscribed diameter that is greater than an external diameter of the inner tube, and the recess may be disposed on a side of the drive component that faces the inner tube.
