PROBLEM TO BE SOLVED: To provide a stop maintenance device of a vehicle which can make compatible both traveling stability and a steering comfort while maintaining a load alleviation function related to a pedal-in operation of a brake pedal.SOLUTION: A stop maintenance device of a vehicle comprises: a foot brake device 2; a DSC device 3 which can apply a brake independently from the brake pedal 5; an EPB device 4 which can apply a brake independently from the brake pedal 5; and an ECU 10 which can perform a first stop mode by operating the DSC device 3 when a stop state is detected. The stop maintenance device also comprises: a first determination part 10a which can determine the existence of an obstruction element which obstructs proper traveling after a stop; a second determination part 10b which can determine a failure of the EPB device 4; a lamp 63; and a speaker 64. When the first determination part 10a determines the existence of the obstruction element, the ECU 10 performs a second stop mode for maintaining the stop state by operating the EPB device 4, and when the second determination part 10b determines the failure of the EPB device 4 in the second stop mode, the ECU operates the lamp 63 and the speaker 64.SELECTED DRAWING: Figure 2
【課題】ブレーキペダルの踏込操作に係る負荷軽減機能を維持しつつ、走行安全性と操縦快適性とを両立することができる車両の停止維持装置を提供する。【解決手段】フットブレーキ装置2と、ブレーキペダル5と独立して制動可能なDSC装置3と、ブレーキペダル5と独立して制動可能なEPB装置4と、停止状態が検出されたときにDSC装置3を作動させて第1停止モードを実行可能なECU10とを備え、停止後の適正な走行を阻害する阻害要因の存在を判定可能な第1判定部10aと、EPB装置4の故障を判定可能な第2判定部10bと、ランプ63及びスピーカ64を備え、ECU10は、第1判定部10aが阻害要因の存在を判定したとき、EPB装置4を作動させて停止状態を維持する第2停止モードを実行し、第2停止モードにおいて第2判定部10bがEPB装置4の故障を判定したとき、ランプ63及びスピーカ64を作動させる。【選択図】 図2
