Provided is a driving support device () including a control device configured to enter, in a first situation that is a situation in which an own vehicle travels in a predetermined region (X) before an intersection and an adjacent traveling lane is absent on a first direction side in a crossing direction of a traveling lane (L) on which the own vehicle is traveling, a state in which start of driving support for changing a traveling direction of the own vehicle to the first direction at the intersection is possible, and enter, in a second situation that is a situation in which the own vehicle travels in the predetermined region (X) and an adjacent traveling lane is present on the first direction side in the crossing direction of the traveling lane (L), a state in which the start of the driving support is impossible. When transition to the second situation occurs without execution of a lane change after the control device enters the state in which the start of the driving support is possible in the first situation, the control device holds the state in which the start of the driving support is possible until a second time point that is one of: a time point when a predetermined time has elapsed from a first time point that is a time point when the transition to the second situation occurs; or a time point when the own vehicle has traveled over a predetermined distance from the first time point.

Driving support device

A driving support apparatus comprises a sensor configured to acquire sensor information that is used to acquire a distance between a vehicle and an object, and a controller configured to execute a driving support control using a first distance, which is acquired by applying a first recognition method to the sensor information, representing a distance between the vehicle and a target object as a control distance. The first recognition method has a characteristic that a recognition reliability of the target object increases as an acquisition time of the first distance increases. The controller is configured to use an extrapolation distance representing the vehicle and the target object as the control distance, when the first distance can no longer be acquired and the acquisition time is equal to or longer than a predetermined threshold time.

Driving support apparatus

A vehicle driving assistance apparatus executes a speed control of controlling a moving speed of an own vehicle to a target speed or less when the own vehicle moves on a curved road, and the moving speed of the own vehicle is greater than the target speed. While executing the speed control, the vehicle driving assistance apparatus controls a deceleration of the own vehicle by the speed control such that a deceleration of the own vehicle realized when an own vehicle moving course is within a drivable area of the curved road, is smaller than the deceleration of the own vehicle realized when a part of the own vehicle moving course is out of an outer boundary of the drivable area.

Vehicle driving assistance apparatus

A vehicle driving assistance apparatus terminates decelerating an own vehicle with a second deceleration characteristic by a deceleration control and starts to decelerate the own vehicle with a first deceleration characteristic by the deceleration control when a predetermined time elapses since an accelerator operation is released while a deceleration target is detected, or when a deceleration intensity of the first deceleration characteristic is equal to or smaller than a predetermined intensity. The apparatus terminates decelerating the own vehicle with a third deceleration characteristic by the deceleration control and starts to decelerate the own vehicle with the first deceleration characteristic by the deceleration control when a predetermined time elapses since a brake operation is released while the deceleration target is detected, or when the deceleration intensity of the third deceleration characteristic is equal to or smaller than a predetermined intensity.

The driving support device includes a vehicle speed control unit that sets a target vehicle speed of the vehicle and controls a speed of the vehicle based on the target vehicle speed, and an operation state determination unit that determines whether or not a turning assistance function that assists turning of the vehicle can be operated in a curve in front of the vehicle. When it is determined that the turning assistance function can be operated, the vehicle speed control unit increases the target vehicle speed in the curve as compared with a case where it is determined that the turning assistance function cannot be operated.

A driving assistance apparatus assists a driver of a vehicle by performing a deceleration control to decelerate the vehicle when the vehicle makes a right turn or a left turn at an intersection. The driving assistance apparatus is configured to make a magnitude of a deceleration of a vehicle while performing a deceleration control of when a left-or-right-turn-condition is not satisfied smaller than a magnitude of a deceleration of the vehicle while performing the deceleration control of when the left-or-right-turn-condition is satisfied, in a case where a distance between the vehicle and the intersection is equal to or shorter than a distance threshold and the vehicle is predicted to change a moving direction to a particular direction, the left-or-right-turn-condition being a condition that is satisfied when the vehicle is permitted to change the moving direction to the particular direction in/from a traveling lane in which the vehicle is running.
