To provide a vehicle assist control device capable of ensuring the safety of a vehicle, by securing uphill travel performance, even if a battery residual quantity decreases.SOLUTION: A vehicle assist control device is equipped with a high-voltage battery 6, a motor 4 that outputs driving force to driving wheels 10 by electric power from the high-voltage battery 6, an engine 2 that outputs driving force to the driving wheels 10 through a clutch 31, and a control portion 8 that executes a plurality of assist controls assisting the driving force of the engine 2 by the driving force of the motor 4. The control portion 8 executes the plurality of assist controls, gradually restricts the execution of the plurality of assist controls as the residual quantity of the high-voltage battery 6 decreases, and finally restricts the execution of the assist control for improving uphill performance assisting the driving force of the engine 2 by the driving force of the motor 4 on an uphill road that is equal to or larger than a predetermined gradient.SELECTED DRAWING: Figure 1
【課題】バッテリ残量が減少しても、登坂走行性能を担保して、車両の安全性を確保することができる車両のアシスト制御装置を提供すること。【解決手段】高電圧バッテリ6と、高電圧バッテリ6からの電力により駆動輪10に駆動力を出力するモータ4と、クラッチ31を介して駆動輪10に駆動力を出力するエンジン2と、エンジン2の駆動力を、モータ4の駆動力でアシストする複数のアシスト制御を実行する制御部8とを備え、制御部8は、複数のアシスト制御を実行し、高電圧バッテリ6の残量が少なくなるに従い、複数のアシスト制御の実行を段階的に制限し、所定勾配以上の登坂路においてエンジン2の駆動力をモータ4の駆動力でアシストする登坂性能向上のためのアシスト制御の実行を最後に制限する。【選択図】図1
