To provide a controller for a vehicle that can execute both temperature raising control and regeneration control over a filter while securing drivability.SOLUTION: The present invention relates to a controller for a vehicle that has an engine as a travel power source, a filter collecting exhausted fine particles from the engine, and a lock-up clutch provided on a power transmission path between the engine and driving wheels. The controller for the vehicle comprises: a determination part which determines whether or not there is a request to raise a temperature of the filter through retardation processing on an ignition period of the engine and a request to regenerate the filter by cutting fuel of the engine; and a control part which releases the lock-up clutch in an accelerator ON state to execute temperature raising control of the filter when there are the request to raise the temperature and the request to regenerate the filter, and engages the lock-up clutch to execute the regeneration control of the filter if the accelerator ON state is switched to an accelerator OFF state after the temperature raising control is completed.SELECTED DRAWING: Figure 3 【課題】ドライバビリティを確保しつつフィルタの昇温制御及び再生制御の双方を実行できる車両の制御装置を提供することを課題とする。【解決手段】走行動力源であるエンジンと、前記エンジンからの排気微粒子を捕集するフィルタと、前記エンジンと駆動輪との間の動力伝達経路上に設けられたロックアップクラッチを有したトルクコンバータと、を備えた車両の制御装置であって、前記エンジンの点火時期の遅角処理による前記フィルタの昇温要求、及び前記エンジンでの燃料カットによる前記フィルタの再生要求があるか否かを判定する判定部と、前記昇温要求及び再生要求がある場合において、アクセルオンの場合に前記ロックアップクラッチを解放して前記フィルタの昇温制御を実行し、前記昇温制御の完了後にアクセルオンからアクセルオフに切り替えられた場合には前記ロックアップクラッチを係合して前記フィルタの再生制御を実行する制御部と、を備えた車両の制御装置。【選択図】図３
