STEERING APPARATUS

摘要

A steering apparatus is provided which can suppress unintended movement of a steering wheel when a clutch is engaged. When a power switch is turned off and a steering wheel is steered, a reaction force control circuit makes a reaction force motor to generate a steering reaction force stronger than a normal steering reaction force to give a driver an appropriate feeling of response according to a steering torque. The strong steering reaction force is applied to a steering shaft to suppress steering of the steering wheel. A steering operation control circuit executes steering operation control, that is, control that makes an actual steered angle equal to a target steered angle based on a steering angle, and then a clutch is engaged. The clutch is engaged after confirmation of an immovable state of steered wheels, and thus rotation of the steering wheel unintended by the driver is suppressed.

主权项

1. A steering apparatus comprising:
a clutch that connects and disconnects a power transmission path between a steering wheel and a steered wheel; a reaction force motor that generates a steering reaction force that is a torque acting in a direction opposite to a steering direction and applied to a portion of the power transmission path located between the steering wheel and the clutch; a steering operation motor that generates a steering operation force that is power making the steered wheel to be steered and that is applied to a portion of the power transmission path located between the clutch and the steered wheel; and a control apparatus that executes engagement and disengagement control for the clutch based on whether or not a clutch engagement condition is satisfied, reaction force control that generates, through the reaction force motor, a steering reaction force corresponding to a steering state, and steering operation control that makes the steered wheel to be steered in accordance with the steering state through the steering operation motor, wherein when the clutch engagement condition is satisfied and a state where the power transmission path is disconnected is switched to a state where the power transmission path is connected, the control apparatus executes rotation suppression control that suppresses rotation of the steering wheel through the reaction force motor or through both the reaction force motor and the steering operation motor.
