Description
上記実施形態においては、偏差導出部としてのオフセットストローク導出部166が、例えば、第一ストロークセンサ41aの故障が検出された時点t1よりも前(直前)の第一導出値としての平均値Lpと、第二ストロークセンサ41bから取得した第二ストロークU2と、の差分である偏差σを導出するようにした。そして、第二導出部としての第二算出用ストローク導出部167が偏差σと、第二ストロークセンサ41bから取得した第二ストロークU2と、を加算した加算値Kを第二導出値として導出するようにした。
上記実施形態においては、第二導出部としての第二算出用ストローク導出部167が偏差σと、時点t1において故障が検出されていない第二ストロークセンサ41bから取得した第二ストロークU2と、を加算した加算値Kを第二導出値として導出するようにした。この場合、故障が検出されていない第二ストロークセンサ41bから取得した第二ストロークU2(第二出力電圧)が、例えば、電源からのノイズの影響やブレーキペダル11の振動等によって増減して変動すると、加算値Kも変動し、ひいては、目標減速度Gd及び目標制動力Bdも変動する可能性がある。
