  • Patent number: 11731637
    Abstract: A driver assistance control device includes a detection part detecting a degree of concentration of a driver; an acquisition part acquiring assistance levels set by the driver; a driver assistance control part performing a plurality of the functions; and a changing part automatically changing setting of the plurality of the functions in accordance with the degree. The changing part automatically changes the settings of first driver assistance functions including one of a plurality of the functions so that the assistance levels become higher than the levels set by the driver when the degree becomes lower than a first value, and automatically changes the settings of second driver assistance functions including at least another of a plurality of the functions so that the assistance levels become higher than the levels set by the driver when the degree becomes lower than a second value different from the first value.

  • Patent number: 11634121
    Abstract: In a driving assistance apparatus, an object detecting unit detects an object that is present in a periphery of an own vehicle based on an image captured by an imaging apparatus provided in the own vehicle. An avoidance control unit performs collision avoidance control for avoiding a collision between the detected object and the own vehicle when a collision between the object and the own vehicle is likely. A light distribution control unit switches irradiated light of an irradiation apparatus provided in the own vehicle between high beam and low beam based on a predetermined switching condition. The light distribution control unit performs switching suppression control to suppress switching of the irradiated light from high beam to low beam while the avoidance control unit is performing collision avoidance control in a case where the irradiated light is set to high beam.

  • Patent number: 11370432
    Abstract: A vehicle control apparatus includes an electric control unit that performs a preceding vehicle trailing control which makes an own vehicle trail a preceding vehicle as an adaptive cruise control, and performs a first brake control which automatically applies a first braking control to the own vehicle when a time-to-collision to a target object is less than a first threshold. In a case where a performing condition for the first brake control has been determined to be satisfied during a performance of the adaptive cruise control, the electric control unit continues performing the adaptive cruise control without performing the first brake control when a deceleration control by the adaptive cruise control is being performed, whereas stops performing the adaptive cruise control when the deceleration control by the adaptive cruise control is not being performed.

  • Patent number: 10850717
    Abstract: A driving assistance apparatus determines, based on an instantaneous indicator which is an instantaneous value of a parameter regarding steering of the own vehicle, whether a driver has started a collision avoidance operation for avoiding a collision between a target and the own vehicle. When it is determined that the collision avoidance operation has been started, a support start timing for starting driving assistance for avoiding the collision between the target and the own vehicle or reducing collision damage is set to be a timing later than when the collision avoidance operation has not been started. The support start timing during a collision avoidance time period which is a time period until a predetermined set time has elapsed after it is determined that the collision avoidance operation has been started is set based on a time-dependent indicator for steering indicated by the instantaneous indicator at timings during the collision avoidance time period.

  • Patent number: 10854081
    Abstract: A driving assistance device sets, in front of an own vehicle, an actuation region that is a region sandwiched by boundary lines, positioned at left and right, respectively. In a case where a target existing around the own vehicle has entered the actuation region, the device performs driving assistance for avoiding collision with the target or mitigating collision damage. The device, when setting the actuation region, in a case where the own vehicle is in a turning state, changes a lateral position of a boundary line in an outside in a turning direction of the own vehicle, of the left and right boundary lines of the actuation region, to a position closer to the own vehicle according to turning information. For a boundary line in an inside in a turning direction of the own vehicle, the device does not change a lateral position according to the turning information.

  • Patent number: 10814841
    Abstract: A controller calculates absolute velocity of an object based on acquired own vehicle velocity and acquired relative velocity of the object with respect to an own vehicle. The controller determines a relative movement state of the object in a direction of movement of the own vehicle based on the calculated absolute velocity of the object. The controller changes a threshold for the absolute velocity of the object to be used for determination of the relative movement state of the object while the automatic brake is actuated.

  • Patent number: 10293817
    Abstract: A hybrid ECU reads mode information during regenerative braking, and gradually decreases regenerative braking force when a friction braking force control in accordance with a preparatory mode is started. Thereby, sudden change of deceleration of a vehicle can be prevented. The hybrid ECU 50 makes regenerative braking force disappear immediately when a friction braking force control in accordance with a collision avoidance braking mode is started during regenerative braking. Thereby, the vehicle can be slowed down with a deceleration for collision avoidance.
