To improve evacuation travel performance.SOLUTION: An evacuation travel control device 40 includes a negative pressure securing control part 40C, a first determination part 40D, and an evacuation travel control part 40E. When driving of an internal combustion engine is stopped due to abnormality of an internal combustion engine, the negative pressure securing control part 40C executes negative pressure securing control so that a brake booster secures a first negative pressure larger than 0. A first determination part 40D determines whether or not the first negative pressure is secured in the brake booster by the negative pressure securing control. When determining that the first negative pressure is secured, the evacuation travel control part 40E sets second speed which is predetermined as a vehicle speed limit value of evacuation travel vehicle speed and is higher than first speed as a vehicle speed limit value, and controls the vehicle so that it performs evacuation travel.SELECTED DRAWING: Figure 3

    【課題】退避走行の走行性能の向上を図る。【解決手段】退避走行制御装置40は、負圧確保制御部40Cと、第1判断部40Dと、退避走行制御部40Eと、を備える。負圧確保制御部40Cは、内燃機関の異常により内燃機関の駆動が停止したときに、ブレーキブースターが0より大きい第1負圧を確保するように負圧確保制御を実行する。第1判断部40Dは、負圧確保制御によりブレーキブースターに第1負圧が確保されたか否かを判断する。退避走行制御部40Eは、第1負圧が確保されたと判断した場合、退避走行車速の車速制限値として予め定められた第1速度より速い第2速度を車速制限値として設定し、退避走行するように制御する。【選択図】図3
