  • Patent number: 11597401
    Abstract: A driving assistance apparatus makes a drive force of a vehicle equal to an erroneous operation coping drive force which is smaller than an ordinary drive force in a period from a satisfaction of an erroneous operation start condition which is satisfied when an accelerator pedal is operated erroneously to a satisfaction of an erroneous operation end condition which is satisfied when the erroneous operation has ended. The erroneous operation coping drive force is set to a first drive force if the erroneous operation start condition becomes satisfied after a reoperation determination time point at which a time threshold elapses from when the erroneous operation end condition became last satisfied. Meanwhile, the erroneous operation coping drive force is set to a second drive force which is greater than the first drive force if the erroneous operation start condition becomes satisfied before the reoperation determination time point.
