Abstract: A vehicle deceleration assistance apparatus executes a deceleration assistance control before a vehicle arrives at a target point. The apparatus executes the deceleration assistance control, setting a deceleration assistance level to a first level when a first condition is satisfied, blinkers are activated, and a second condition is satisfied. The first condition is a condition that a target point distance between the vehicle and the target point is equal to or shorter than a first distance. The second condition is a condition that the target point distance is equal to or longer than a second distance shorter than the first distance. The apparatus executes the deceleration assistance control, setting the deceleration assistance level to a second level lower than the first level when the first condition is satisfied, the blinkers are activated, and the second condition is not satisfied.

Abstract: A driving assistance apparatus is configured to perform an assistance control of assisting in driving a vehicle, when a first condition and a second condition are satisfied, in a situation in which a target is recognized. The driving assistance apparatus is provided with: a determinator configured to determine a state of the assistance control. The determinator is configured (i) to determine that the state of the assistance control is a standby state if a standby condition is satisfied, wherein the standby condition requires that the first condition is satisfied, but the second condition is not satisfied, in the situation in which the target is recognized, and (ii) to determine that the state of the assistance control is an interruption state if an interruption condition is satisfied, wherein the interruption condition requires that the first condition is no longer satisfied while the satisfaction of the standby condition is continued.

Abstract: 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.

Abstract: 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.

Abstract: In a driving assist device, an electronic control unit is configured to determine whether a target position is able to be decided from a predetermined object indicating that a vehicle needs to be decelerated, when recognizing the predetermined object, to perform a first assist by which the vehicle is decelerated at a first deceleration that is changed based on a brake operation by a driver, when determining that the target position is not able to be decided, and to perform a second assist by which the vehicle is decelerated at a second deceleration that is equal to or higher than a predetermined deceleration necessary to decelerate the vehicle to the target velocity before the vehicle reaches the target position decided from the predetermined object, when determining that the target position is able to be decided.

Abstract: An auxiliary current amount that is used in an auxiliary that is mounted in a vehicle is calculated. A stop time ratio of the vehicle is calculated based on a running history of the vehicle, and an estimated stop time of the vehicle that is estimated based on the stop time ratio is calculated. An SOC threshold is set based on an estimated consumption current amount that is obtained from the estimated stop time and the auxiliary current amount. A generator that is mounted in the vehicle is operated such that a value of a storage state of the battery recovers to become larger than the SOC threshold when the value of the storage state of the battery is smaller than the SOC threshold.

Abstract: 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.

Abstract: 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.

Abstract: 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.
