To provide a device for determining failure of vehicle control, capable of appropriately determining the presence or the absence of the failure of the vehicle control.SOLUTION: The device for determining failure of vehicle control comprises: a relay circuit; and a control part. The control part executes a failure determination process of the relay circuit. The relay circuit comprises: a power supply circuit; and a relay switch. The relay switch comprises: a first contact point; a second contact point; an output side contact point; a coil; and a movable piece. The control part determines that the relay switch is normal when a potential of the output side contact point when the coil is in a non-conductive state matches a first target value, and the potential of the output side contact point when the coil is in a contact state matches a second target value, and determines that there is something wrong with the relay switch when at least one of them does not match the target value.SELECTED DRAWING: Figure 4

    【課題】適切に車両制御の故障の有無を判断することが可能な車両制御の故障判断装置を提供する。【解決手段】車両制御の故障判断装置は、リレー回路と、制御部と、を備える。制御部は、リレー回路の故障判断処理を実行する。リレー回路は、電源回路と、リレースイッチと、を備える。リレースイッチは、第1接点と、第2接点と、出力側接点と、コイルと、可動片と、を備える。制御部は、コイルを非通電状態にした場合における出力側接点の電位が第1目標値に一致し、且つ、コイルを通電状態にした場合における出力側接点の電位が第2目標値に一致した場合に、リレースイッチを正常と判断し、少なくとも一方が一致しない場合に、リレースイッチを故障と判断する。【選択図】図4
