Claims (5)
- 外部からの操作によりデューティ比を連続的に変更可能なPWM信号を出力する調光装置からの前記PWM信号に基づいて調光率を決定し該調光率に基づいて光源の調光制御を行うメータ装置を備えた車両用メータ調光装置であって、
前記メータ装置は、前記調光装置が出力する前記PWM信号の前記デューティ比の所定時間内の変化率が所定値を越えた場合に、前記調光装置の出力信号の異常と判定し、前記PWM信号に基づいて決定した調光率に基づいた前記調光制御の代わりに、所定の調光制御を行うことを特徴とする車両用メータ調光装置。 - 前記所定の調光制御は、所定の調光率に前記光源を発光させることを特徴とする請求項1に記載の車両用メータ調光装置。
- 前記所定の調光制御は、所定の調光率に前記光源を発光させると共に、所定の周期で前記光源の発光光量を変化させることを特徴とする請求項1に記載の車両用メータ調光装置。
- 前記デューティ比の所定時間内の変化率の前記所定値は、外部からの操作により前記所定時間内にデューティ比を可変する際の変化率の最大値を越える値であることを特徴とする請求項1〜3のいずれか1項に記載の車両用メータ調光装置。
- 前記所定時間は、前記調光装置が出力する前記PWM信号の周期の整数倍であることを特徴とする請求項1〜4のいずれか1項に記載の車両用メータ調光装置。
