| description | To suppress a relay from being welded while enabling electric power to be supplied to an auxiliary machine, when an abnormality occurs in communication between an electronic control unit (ECU) and a DC/DC converter.SOLUTION: An ECU of a control device of a vehicle performs communication with a DC/DC converter connected to a battery through a relay, so as to command to start and stop the DC/DC converter. A converter control part of the control device controls the DC/DC converter on the basis of the command from the ECU. In a state where the relay is in a connection state when an abnormality occurs in the communication, the converter control part controls the DC/DC converter so that a constant voltage operation of supplying electric power to an auxiliary machine is continued under a condition that the input voltage of the DC/DC converter based on a voltage sensor is higher than a voltage for a securing operation of the auxiliary machine. When the abnormality occurs, the ECU counts the number of times at which the relay is shut off during system start-up of the vehicle and, when the number of times is equal to or more than a threshold, prohibits the relay from being connected.SELECTED DRAWING: Figure 2
【課題】電子制御ユニット（ＥＣＵ）とＤＣ／ＤＣコンバータとの通信の異常時に、補機への電力供給の継続を可能としつつリレーの溶着を抑制できるようにする。【解決手段】車両の制御装置のＥＣＵは、リレーを介して電池と接続されるＤＣ／ＤＣコンバータとの間で通信を行い、ＤＣ／ＤＣコンバータの起動／停止を指令する。制御装置のコンバータ制御部は、ＥＣＵからの指令に基づいて、ＤＣ／ＤＣコンバータを制御する。上記通信に異常が生じた際にリレーが接続状態である場合、コンバータ制御部は、電圧センサに基づくＤＣ／ＤＣコンバータの入力電圧が補機の動作保証電圧よりも高いことを条件として補機に電力を供給する定電圧動作を継続するようにＤＣ／ＤＣコンバータを制御する。上記異常が生じている時、ＥＣＵは、車両のシステム起動中にリレーを遮断した回数をカウントし、当該回数が閾値以上となった場合にはリレーの接続を禁止する。【選択図】図２ |
