PROBLEM TO BE SOLVED: To provide a drive power control apparatus capable of limiting cumbersomeness in acceleration-deceleration operations by obtaining optimal deceleration in accordance with the intention of a driver.SOLUTION: A controller 4, for use in controlling drive power, performs: calculating target acceleration G1 on the basis of a present driving state; calculating a difference between a present vehicular speed Vp and a recommended vehicular speed Vr, in a case where the present vehicular speed Vp exceeds the recommended vehicular speed Vr due to a decrease in a predetermined recommended vehicular speed Vr; calculating elapsed time since the present vehicular speed Vp has exceeded the recommended vehicular speed Vr; determining an intention of the driver for deceleration; and correcting the target acceleration G1 so as to increase the deceleration in a case where there is the intention of the driver for deceleration, after the present vehicular speed Vp exceeds the recommended vehicular speed Vr. Further, a correction amount for correcting the target acceleration increases with a difference in vehicular speeds and inversely with the length of the elapsed time.SELECTED DRAWING: Figure 1
【課題】運転者の意図に応じた最適な減速度を得ることにより加減速操作の煩雑さを抑制することができる駆動力の制御装置を提供する。【解決手段】駆動力を制御するコントローラ4は、現在の運転状態に基づき目標加速度G1を算出し、予め定められた推奨車速Vrの低下により現在車速Vpが推奨車速Vrを上回った場合に、現在車速Vpと推奨車速Vrとの差を算出し、現在車速Vpが推奨車速Vrを上回ってからの経過時間を算出し、運転者の減速意志を判定し、現在車速Vpが推奨車速Vrを上回った後に、運転者が減速意志のあることが判定された場合に減速度が大きくなるように目標加速度G1を補正するように構成され、目標加速度を補正する補正量は、車速の差が大きいほど大きくし、経過時間が長いほど小さくするように構成されている。【選択図】図1
