  • Publication number: 20240109412
    Abstract: A driving assistance apparatus includes a parking lot staying determination section which determines whether or not a vehicle is present in a parking lot having a parking row including parking slots and/or parked vehicles located adjacent to each other, an erroneous operation determination section which determines whether or not an occupant has erroneously stepped on an acceleration operation element, and a control section which executes driving power reduction control upon determination that the vehicle is present in the parking lot and that the occupant has performed the erroneous operation. When the erroneous operation determination section determines that the occupant has performed the erroneous operation again before elapse of a predetermined threshold time after execution of the driving power reduction control, the control section executes the driving power reduction control again, irrespective of the result of the determination by the parking lot staying determination section.

  • Publication number: 20240092346
    Abstract: Provided is a driving support device (1) including a control device which has an acceleration suppression function of suppressing acceleration of an own vehicle when the own vehicle is determined to be positioned in a parking area (PA) including a parking spot row (PSA) and an erroneous depression operation is determined to be executed on an accelerator pedal (AP). The control device predicts a trajectory (T) of the own vehicle in a case in which the own vehicle travels when a speed (vs) of the own vehicle is equal to or higher than a predetermined speed, and further predicts a time (?t) required for the own vehicle to reach a point at which the trajectory (T) and the parking spot row (PSA) intersect with each other. The control device determines that the own vehicle is positioned in the parking area (PA) when the predicted time (?t) is equal to or shorter than a predetermined time.
