Description

동력조향장치(power steering apparatus)Power steering apparatus

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

도변은 본 발명의 1실시예를 표시하는 것으로서, 제1도는 본 발명에 관한 동력조향장치의 구성을 표시하는 중요부분 블록도.Fig. 1 shows one embodiment of the present invention, and Fig. 1 is a block diagram showing an important part of the structure of a power steering apparatus according to the present invention.

제2도는 그 동작설명을 위한 순서도.2 is a flow chart for explaining its operation.

제3도는 조향모우터의 전류치제어에 있어서 모우터전류와 입력토오크와의 관계를 표시하는 그래프.3 is a graph showing the relationship between the motor current and the input torque in the current value control of the steering motor.

Claims (1)

자동차의 조향기구에 축을 개재하여 연동연결된 조향륜의 회전력을 검출하는 토오크센서(2)를 구비하고 그 토오크센서(2)의 검출치에 따라 전기한 조향기구를 전자클러치(8)를 개재하여 동작시키는 조향보조용 모우터(6)를 구비하여 이루어진 동력조향장치에 있어서, 전기한 토오크센서의 검출신호의 위상을 앞서게하는 진위상회로(3)와, 전기한 자동차의 주행속도를 검출하는 차속검출장치와, 그 차속검출장치의 검출속도가 소정속도 미만인 경우에 전기한 진위상회로의 출력신호를 사용하여 전기한 조향보조용 모우터(6)으로의 전류치를 검출속도에 따라 제한하는 전류치제한장치와, 전기한 차속 검출장치의 검출속도가 전기한 소정속도 이상인경우에 전기한 전자클러치(8)을 이탈하는 클러치제어장치와, 그 클러치제어장치에 의하여 이탈된 전기한 전자클러치(8)를 연결할 때에 전기한 모우터로의 전류치를 전기한 토오크센서(2)의 검출신호를 미분한 신호에 입각하여 조절하는 장치를 구비하는 것을 특징으로 하는 동력조향장치.The steering mechanism of the vehicle is provided with a torque sensor 2 for detecting the rotational force of a steering wheel interlocked via a shaft, and the steering mechanism electrically operated according to the detected value of the torque sensor 2 is operated via the electromagnetic clutch 8. A power steering apparatus comprising a steering assistance motor (6), comprising: a true phase circuit (3) for advancing a phase of a detection signal of an electric torque sensor and a vehicle speed detection for detecting a traveling speed of an electric vehicle; The device and the current limiting device for limiting the current value to the steering assist motor 6 described above by using the output signal of the true phase circuit described above when the detection speed of the vehicle speed detection device is less than the predetermined speed according to the detection speed. And a clutch control device releasing the electric clutch 8, when the detected speed of the vehicle speed detecting device is greater than or equal to the predetermined speed, and an electric limit deviated by the clutch control device. Here power steering apparatus comprising a control on the basis of a differential of the detection signal of the electric current to the electric Motor torque sensor 2 signal device when connecting the clutch (8). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
