Description
はじめに、パワーウィンドウシステムの構成の概略について説明する。図1は、本実施の形態に係るパワーウィンドウシステムの構成を示す模式図である。図2は、本実施の形態に係るモータの出力軸近傍の斜視図である。 (Configuration of power window system)
First, an outline of the configuration of the power window system will be described. FIG. 1 is a schematic diagram showing a configuration of a power window system according to the present embodiment. FIG. 2 is a perspective view of the vicinity of the output shaft of the motor according to the present embodiment.
上述のパワーウィンドウシステム10は、ドアガラス16を開閉する際にドアガラス16と枠体18との間に異物を挟み込んだ場合、その挟み込みを検出するための挟み込み検出装置を備えている。図3は、本実施の形態に係る挟み込み検出装置の構成を示すブロック図である。 (Pinch detection device)
The
次に、上述のパワーウィンドウシステムにおける挟み込み検出方法について説明する。図4(a)、図4(b)は、ドアガラスが閉動中に異物が挟み込まれた際のドアガラスの位置とモータの回転速度との関係を示した図である。スイッチ操作によりドアガラス16の閉動が指示されると、スイッチ入力回路44を介してその信号を受けたマイクロコンピュータ48は、モータ駆動回路40によりモータ本体20を駆動させる。その際、パワーウィンドウシステム10に異常がなければ、ドアガラス16の上端が枠体18に突き当たるまでは、モータ本体20の回転速度は図4(a)に示すように一定速度S0となる。ところが、ドアガラス16の上端が枠体18に正常に突き当たる前に、ドアガラス16と枠体18との間に異物が挟まれると、モータ本体20の回転速度は急激に低下する。 (Pinch detection method)
Next, a pinching detection method in the power window system described above will be described. FIG. 4A and FIG. 4B are diagrams showing the relationship between the position of the door glass and the rotation speed of the motor when a foreign object is caught while the door glass is closed.

はじめに、本実施の形態に係る挟み込み検出装置における設定モードによってしきい値を設定する方法の原理について説明する。なお、以下ではDCモータを例にとり説明するが、回転数とトルクとに相関があるモータであれば他の方式のモータであってもよい。 (Setting mode)
First, the principle of a method for setting a threshold value according to a setting mode in the pinch detection apparatus according to the present embodiment will be described. In the following, a DC motor will be described as an example, but other types of motors may be used as long as the motor has a correlation between the rotation speed and the torque.
H=D/(P1-P2)・・・式(1) The
H = D / (P1-P2) Formula (1)
N×H=N×D/(P1-P2)・・・式(2) When the reduction ratio of the
N × H = N × D / (P1-P2) Expression (2)
N×D/(P1-P2)=πL・・・式(3) In the wire regulator shown in FIG. 6, when the diameter of the
N × D / (P1−P2) = πL (3)
F=2×T/L・・・式(4) Next, when the diameter of the
F = 2 × T / L (4)
ΔT=(S0-S1)×(Ts/N0)・・・式(5) A general DC motor has a correlation between torque and rotation speed. FIG. 7 is a performance diagram in a general DC motor. In such a DC motor, as shown in FIG. 7, when the motor speed changes ΔS (= S 0 -S 1 ), the torque change generated by the motor is ΔT (T 1 -T 0 ). Become. Therefore, based on the correlation between the torque and the rotational speed shown in FIG. 7, assuming that the no-load rotational speed is N 0 [rpm] and the stationary torque is Ts [N · m], the torque change ΔT can be expressed by the following formula ( 5).
ΔT = (S 0 −S 1 ) × (Ts / N 0 ) (5)
F=(S0-S1)×(Ts/N0)×2π×(P1-P2)/(N×D)・・・式(6)
ここでFは挟み込み荷重に相当する。挟み込み荷重Fとは、挟み込まれた異物に働いているとされる荷重であり、誤作動の防止と安全性を両立する範囲で適宜決められるものである。目標となる挟み込み荷重Fが小さい場合、パワーウィンドウシステム10の各構成の交差や振動などの外乱によって誤作動、例えば、異物が挟み込まれていないにも関わらずドアガラス16が反転動作するといった状態が発生し得る。一方、目標となる挟み込み荷重Fが大きい場合、ドアガラス16が反転動作するまでに異物にかかる荷重が過大となる可能性がある。 Therefore, when Expression (3), Expression (4), and Expression (5) are considered, the relationship shown in Expression (6) is established.
F = (S 0 −S 1 ) × (Ts / N 0 ) × 2π × (P1−P2) / (N × D) (6)
Here, F corresponds to the sandwiching load. The sandwiching load F is a load that is assumed to act on the sandwiched foreign matter, and is determined as appropriate within a range in which malfunction prevention and safety are compatible. When the target sandwiching load F is small, a malfunction occurs due to disturbance such as crossing or vibration of each component of the
