Abstract
【解決手段】コンバータは、IGBT素子とダイオードとを1つのチップで構成した上アームを備える。ECUは、上アームの過熱保護を行なう場合、コンバータの制御状態などからIGBT素子の推定温度を算出し、上アーム温度の検出値がIGBT素子の推定温度よりも高く、かつ上アーム温度の検出値がダイオードの保護温度以上である場合、バッテリからの放電を制限し、上アーム温度の検出値がIGBT素子の推定温度以下であり、かつ上アーム温度の検出値がIGBT素子の保護温度以上である場合、バッテリへの充電を制限する。
【選択図】図7
Description
図2は、モータジェネレータMGの力行時(バッテリ10の放電時)における、コンバータ30のスイッチング動作と電流の流れとを模式的に示す図である。図2(A)に示す状態は、IGBT素子Q1,Q2をそれぞれオフ状態(非導通状態)、オン状態(導通状態)とする状態である。図2(B)に示す状態は、IGBT素子Q1,Q2をそれぞれオン状態、オフ状態とする状態である。
以上のような構成を有する車両1において、バッテリ10の充放電に伴なってコンバータ30内の各部(IGBT素子Q1,Q2およびダイオードD1,D2)に電流が流れると、各部において熱が発生する。各部の発熱量は、コンバータ30の通電量、昇圧比(VL/VH)、スイッチング周波数(単位時間あたりのスイッチング回数)、さらには動作状態(力行時の動作なのか回生時の動作なのか)などによって異なる。したがって、コンバータ30内の各部の過熱を適切に防止するためには、温度センサによって各部の温度を検出し、各部の温度がそれぞれの許容温度を超えないようにバッテリ10の充放電を制限することが望ましい。
Q2推定温度=冷却水温TW+温度差ΔTQ2 …(2)
図7は、ECU100がコンバータ30の上アーム31の過熱保護を行なう際の処理手順を示すフローチャートである。このフローチャートは所定周期で繰り返し実行される。
上述の実施の形態においては、図8のS38にて、放電電力上限値WOUTを制限することによってIGBT素子Q2の過熱を抑制した。しかしながら、図8のS38にて、放電電力上限値WOUTを制限することに代えて、コンバータ30の上アームオン制御(上アームのIGBT素子Q1を常時オン状態にし、下アームのIGBT素子Q2を常時オフ状態にする制御)を行なうようにしてもよい。上アームオン制御を行なうことにより、下アームにおいては、電流がダイオードD2を流れ、IGBT素子Q2を流れなくなるため、IGBT素子Q2の過熱をより効率よく抑制することができる。
