BRAKE DEVICE FOR VEHICLE

PROBLEM TO BE SOLVED: To provide a brake device for a vehicle which dissolves at least a part of a function limit to a determination object, in the brake device for the vehicle having the determination object which contributes to a function for making wheels of the vehicle generate brake forces, and a failure determination part which determines whether or not a failure occurs in the determination object.SOLUTION: In a brake device for a vehicle which comprises a determination object which contributes to a function for making wheels of the vehicle generate brake forces, a failure determination part which determines whether or not a failure occurs in the determination object, and a volatile memory which stores a determination result by the failure determination part, and controls the determination object on the basis of the determination result by the failure determination part, when power supply to the volatile memory is stopped in a state that a probability that a brake operation is performed is high, the determination result which is stored in the volatile memory is stored in a non-volatile memory.SELECTED DRAWING: Figure 4 【課題】車両の車輪に制動力を発生させる機能に寄与する判定対象とその判定対象に故障が生じているか否かを判定する故障判定部とを備える車両用制動装置であって、判定対象に対する機能制限の少なくとも一部を解消する車両用制動装置を提供する。【解決手段】車両の車輪に制動力を発生させる機能に寄与する判定対象と、判定対象に故障が生じているか否かを判定する故障判定部と、故障判定部による判定結果を記憶する揮発性メモリとを備え、故障判定部による判定結果に基づいて判定対象を制御する車両用制動装置において、ブレーキ操作が行われる蓋然性が高い状態で、揮発性メモリへの電力供給を停止するに際し、揮発性メモリに記憶されている判定結果を不揮発性メモリに記憶する。【選択図】図４
