Abstract

Provided is a driving support device ( 1 ) including: an operation sensor configured to acquire operation information that is information on an operation on a driving operation device included in an own vehicle; a periphery sensor configured to acquire peripheral information that is information on a target object existing in a periphery of the own vehicle; and a control device configured to execute deceleration support control of supporting a driving operation executed by a driver to decelerate the own vehicle when existence of a target object in front of the own vehicle is detected based on the peripheral information and a predetermined precondition relating to the target object and the own vehicle is satisfied. The control device determines, when the precondition is satisfied and an operation of depressing a brake pedal of the own vehicle is released, a mode of the deceleration support control based on information on one or both of a steering angle and a position of the own vehicle in a crossing direction on a travel lane on which the own vehicle is traveling at a time point when the precondition is satisfied and the operation of depressing the brake pedal of the own vehicle is released.

First claim

What is claimed is:

1 . A driving support device, comprising:
an operation sensor configured to acquire operation information that is information on an operation on a driving operation device included in an own vehicle; a periphery sensor configured to acquire peripheral information that is information on a target object existing in a periphery of the own vehicle; and a control device configured to execute deceleration support control of supporting a driving operation executed by a driver to decelerate the own vehicle when existence of a target object in front of the own vehicle is detected based on the peripheral information and a predetermined precondition relating to the target object and the own vehicle is satisfied, wherein the control device is configured to determine, when the predetermined precondition is satisfied and an operation of depressing a brake pedal of the own vehicle is released, a mode of the deceleration support control based on information on one or both of a steering angle and a position of the own vehicle in a crossing direction on a travel lane on which the own vehicle is traveling at a time point when the predetermined precondition is satisfied and the operation of depressing the brake pedal of the own vehicle is released.

2 . The driving support device according to claim 1 , wherein the control device is configured to:
execute first deceleration support control when the steering angle is equal to or smaller than a threshold value; execute second deceleration support control that is driving support at a level lower than a level of the first deceleration support control when the steering angle is larger than the threshold value and the position of the own vehicle in the crossing direction is within a lane line of the travel lane; and execute third deceleration support control that is driving support at a level lower than the level of the second deceleration support control when the steering angle is larger than the threshold value and the position of the own vehicle in the crossing direction is beyond the lane line of the travel lane.

3 . The driving support device according to claim 2 , wherein the control device is configured to execute fourth deceleration support control that is driving support at a level higher than the level of the first deceleration support control when the predetermined precondition is satisfied and an operation of depressing an accelerator pedal of the own vehicle is released.

4 . A driving support method, comprising:
acquiring operation information that is information on an operation on a driving operation device included in an own vehicle; acquiring peripheral information that is information on a target object existing in a periphery of the own vehicle; and executing deceleration support control of supporting a driving operation executed by a driver to decelerate the own vehicle when existence of a target object in front of the own vehicle is detected based on the peripheral information and a predetermined precondition relating to the target object and the own vehicle is satisfied, wherein the executing deceleration support control includes determining, when the predetermined precondition is satisfied and an operation of depressing a brake pedal of the own vehicle is released, a mode of the deceleration support control based on information on one or both of a steering angle and a position of the own vehicle in a vehicle width direction on a travel lane on which the own vehicle is traveling at a time point when the predetermined precondition is satisfied and the operation of depressing the brake pedal of the own vehicle is released.

5 . A non-transitory storage medium storing a driving support program for causing a computer of an own vehicle to execute:
acquiring operation information that is information on an operation on a driving operation device included in the own vehicle; acquiring peripheral information that is information on a target object existing in a periphery of the own vehicle; and executing deceleration support control of supporting a driving operation executed by a driver to decelerate the own vehicle when existence of a target object in front of the own vehicle is detected based on the peripheral information and a predetermined precondition relating to the target object and the own vehicle is satisfied, wherein the executing deceleration support control includes determining, when the predetermined precondition is satisfied and an operation of depressing a brake pedal of the own vehicle is released, a mode of the deceleration support control based on information on one or both of a steering angle and a position of the own vehicle in a vehicle width direction on a travel lane on which the own vehicle is traveling at a time point when the predetermined precondition is satisfied and the operation of depressing the brake pedal of the own vehicle is released.
