  • 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.

  • Publication number: 20230256967
    Abstract: A vehicle control apparatus is provided with a reliability determination unit that determines a reliability related to an own vehicle location as a current location of the own vehicle being in a parking place, using a detection result of a parking space or a parked vehicle around an own vehicle based on image data around the own vehicle captured by a camera; and an own vehicle location determination unit that determines whether the own vehicle location is in the parking place, using a determination result of the reliability determined by the reliability determination unit.

  • Publication number: 20230249682
    Abstract: A driving support device including: an in-vehicle sensor configured to acquire and output each of position information relating to a position of an own vehicle, target information relating to a target positioned around the own vehicle, and operation information relating to an operation of an operating element of the own vehicle; and a control device having a lane departure prevention function for preventing the own vehicle from departing from a lane in which the own vehicle is traveling by activating at least one device among a notification device, a drive device, and a braking device mounted on the own vehicle in a situation in which an accelerator pedal of the own vehicle is erroneously operated and an angle between a traveling direction of the own vehicle and a boundary line of the lane detected based on the target information is equal to or less than a predetermined threshold value.

  • Publication number: 20230227039
    Abstract: Provided is an acceleration suppression apparatus having improved practicality. The acceleration suppression apparatus includes: an in-vehicle sensor (20) configured to acquire information relating to a position of an own vehicle and information relating to an operation of an operating element of the own vehicle to output the acquired information; and a parking assist ECU (10) configured to execute, based on the information acquired from the in-vehicle sensor (20), acceleration suppression control for suppressing acceleration of the own vehicle by controlling at least one of a drive device (30) or a braking device (40) mounted on the own vehicle. The parking assist ECU (10) is configured to execute the acceleration suppression control when, in a situation in which the own vehicle is positioned in a predetermined region including a parking space, a traveling mode of the own vehicle matches a predetermined mode defined in advance as a traveling mode when the own vehicle is being parked in the parking space.

  • Publication number: 20230035434
    Abstract: A vehicle driving assistance device includes a processor. The processor is configured to execute acceleration suppression control for suppressing acceleration of a driver's vehicle in a case where a predetermined prohibition condition is not satisfied when an erroneous acceleration operation precondition is satisfied while a traveling condition is satisfied. The traveling condition is a condition for determining that the driver's vehicle is traveling. The erroneous acceleration operation precondition is a precondition for determining that an acceleration operation is erroneously performed. The acceleration operation is an operation performed by a driver of the driver's vehicle to request the acceleration of the driver's vehicle. The predetermined prohibition condition is based on a relationship between the driver's vehicle and an external environment of the driver's vehicle.

  • Publication number: 20220161812
    Abstract: A vehicle control apparatus executes a driving force limiting control when a mistaken operation condition is satisfied. The vehicle control apparatus determines that the mistaken operation condition is satisfied when a third condition is satisfied at a point in time when a second condition becomes satisfied, determines that the mistaken operation condition is not satisfied when the third condition is not satisfied at a point in time when the second condition becomes satisfied, the third condition becomes satisfied within a first time threshold since a first condition becomes satisfied, and a pressing condition is satisfied before the third condition becomes satisfied, and determines that the pressing condition is satisfied when an operation amount of an acceleration operator is greater than or equal to a positive second operation amount threshold, and an operation speed of the acceleration operator is greater than or equal to a positive second operation speed threshold.

  • Patent number: 8428862
    Abstract: An object is to be able to accurately discriminate an object of a collision. A device has a collision detection to which are connected a pressure sensor that detects pressure within a pressure chamber, and a vehicle speed sensor that detects vehicle speed, and the collision detection determines effective mass of a collided object on the basis of an integrated value obtained by integrating, at a predetermined sectional integration width, detection results of the pressure sensor, and a converted vehicle speed signal obtained by subtracting a predetermined value ? from a vehicle speed signal of the vehicle speed sensor by using a predetermined vehicle speed converting map or the like. Then, when the determined effective mass exceeds a predetermined threshold value, the collided object is discriminated as a pedestrian.
