  • Patent number: 11938930
    Abstract: A vehicle control apparatus selects, as a first group, objects in a predetermined area from objects included in object information, selects, as a second group, an upper limit number of the objects from the first group in descending order of a priority value when the number of the objects of the first group is greater than the upper limit number, and executes a collision avoidance control when an index value satisfies a predetermined condition. The priority value represents a probability that the own vehicle collides with the object. The apparatus reduces the priority value of a particular object of the first group when the moving speed of the own vehicle is equal to or lower than a moving speed threshold. The particular object is an object which is deemed to have a moving speed lower than a moving speed of a four-wheel vehicle.

  • Patent number: 11919533
    Abstract: An alert apparatus starts alerting a driver of a host vehicle, when an oncoming vehicle, that is an other vehicle traveling in an oncoming lane with respect to a traveling lane in which the host vehicle is traveling so as to approach the host vehicle and that is predicted to pass through on a specific direction side with respect to a current position of the host vehicle, is present, a turn signal indicator of the host vehicle corresponding to the specific direction side is being operated, and it is likely that the host vehicle starts turning to the specific direction side.

  • Patent number: 11834072
    Abstract: A driving assist apparatus executes an autonomous braking control when a predetermined autonomous stop condition becomes satisfied, executes a stopped state keeping control to keep the own vehicle stopped after stopping the own vehicle by the autonomous braking control, and terminates executing the stopped state keeping control when a predetermined stopped state keeping termination condition becomes satisfied while executing the stopped state keeping control. The driving assist apparatus executes a driving force limitation control to limit a driving force generated to move the own vehicle to a value smaller than the driving force which depends on an amount of operating the acceleration pedal when determining that the predetermined stopped state keeping termination condition is satisfied, and a mistaken pressing operation occurs. The mistaken pressing operation is an operation performed by a driver to mistakenly press an acceleration pedal with an intention to press a brake pedal.

  • Patent number: 11760344
    Abstract: Collision avoidance assist apparatus comprises an object information acquiring apparatus for acquiring, as object information, information on a three-dimensional object as well as dividing lines defining a travelling lane in front of a vehicle, and a control unit configured to, when a collision possibility with a three-dimensional object is high, identify this object as a target object. When one of the dividing lines has been detected without any discontinuation in a predetermined region as well as a part of an other dividing line has not been detected therein, if the control unit determines, based on the object information, that a second condition which is satisfied when the target object is positioned on the other dividing line and is moving in a same direction as an extending direction is satisfied and an avoidance route exists, the control unit performs automatic steering control so that the vehicle travels along the avoidance route.

  • Patent number: 11731621
    Abstract: When a collision avoidance target is a pedestrian or a bicycle, a driving assistance ECU performs automatic braking control. In this case, accelerator override cannot be performed. When the collision avoidance target is an automobile and when an accelerator operation amount is equal to or larger than a first operation amount threshold, the driving assistance ECU prohibits the automatic braking control. In this case, the accelerator override can be performed. When the accelerator operation amount is smaller than the first operation amount threshold, the driving assistance ECU performs the automatic braking control.

  • Patent number: 11615708
    Abstract: Provided is a collision avoidance control apparatus including a first sensor; a second sensor; a controller configured to execute collision avoidance control; and a memory configured to, when a specific object has been detected, record information on the detected specific object, the specific object being an object which has been detected by both of the first sensor and the second sensor, in which the controller is configured to execute the collision avoidance control when determining that there is an object based on any one of the first sensor and the second sensor, and determining that the object has been already recorded as the specific object in the memory.

  • Patent number: 11518375
    Abstract: When a driving assist ECU determines that a mistaken pedal operation has occurred, it starts an automatic brake control, and thereafter, ends the automatic brake control when a steering operation rate ? is greater than a threshold ?f (?>?f). Whereas, when the ECU determines that the mistaken pedal operation has not occurred, it performs a steering override control and does not perform the automatic brake control, when a steering operation amount ? is greater than a threshold ?e or when the steering operation rate ? is greater than the threshold.

  • Patent number: 11479240
    Abstract: A collision avoidance assist apparatus starts an autonomous steering control to autonomously steer and turn an own vehicle to orient the own vehicle in a laterally extending direction of an obstacle to avoid a collision of the own vehicle with the obstacle when the own vehicle potentially collides with the obstacle. The apparatus sets a first condition as a control termination condition used to determine whether to terminate the autonomous steering control, based on a laterally extending direction of the obstacle relative to the own vehicle when starting the autonomous steering control. The apparatus terminates the autonomous steering control when the obstacle is tracked, and a second condition different from the first condition becomes satisfied. The apparatus terminates the autonomous steering control when the obstacle is not tracked, and the first condition becomes satisfied.

  • Publication number: 20220258731
    Abstract: A collision avoidance assist apparatus includes: a front-and-lateral target information acquisition device configured to acquire front-and-lateral target information; a vehicle information acquisition device configured to acquire vehicle information including a vehicle speed and at least one of a yaw rate or a steering input value; and a control unit configured to execute collision avoidance assist control when a target satisfies a collision condition that is satisfied when the target is determined to have collision possibility. The control unit selects targets that satisfy a predetermined selection condition from targets in the front-and-lateral target information, determines whether the collision condition is satisfied for each selected target, determines, when this determination is to be made, whether an own vehicle is turning based on the vehicle information, and changes the selection condition between a case in which the own vehicle is not turning and a case in which the own vehicle is turning.

  • Patent number: 11370431
    Abstract: A vehicle control device comprises an operation amount sensor for measuring an operation amount of an accelerator element, an object sensor for detecting an object ahead of a vehicle, and a controller for applying a normal operation drive force which is determined depending on the operation amount to the vehicle. The controller executes an adaptive cruise control for applying a drive force required for an acceleration of the vehicle to become equal to an adaptive cruise control acceleration to the vehicle. The adaptive cruise control acceleration is an acceleration which increases as a difference between an inter-vehicle distance from the vehicle to an objective-forward-vehicle and a target inter-vehicle distance increases. When an erroneous operation start condition becomes satisfied, the controller ends the adaptive cruise control, and executes an erroneous operation related control for applying a drive force which is smaller than the normal operation drive force to the vehicle.
