Abstract
An electric power steering device includes a torque sensor provided between a steering wheel and steered wheels mounted on a vehicle body; an assist device that adds an assist force when the steered wheels are steered according to a torque detected by the torque sensor; and a vibration suppressor that outputs a vibration suppressing force from the assist device to suppress a vibration of a steering system according to a signal of a predetermined frequency band of the torque.
Claims6
An electric power steering device comprising:
- a torque sensor provided between a steering wheel and steered wheels mounted on a vehicle body;
- an assist device that adds an assist force when the steered wheels are steered according to a torque detected by the torque sensor;
- and
- a vibration suppressor that outputs a vibration suppressing force from the assist device to suppress a vibration of a steering system according to a signal of a predetermined frequency band of the torque, wherein
- the vibration suppressor is controlled to output the vibration suppressing force when a rotational speed detected by a rotational speed detector that detects a rotational speed of a power device that drives the vehicle is a predetermined value.
