Driving support device for vehicle, driving support method for vehicle, and a non-transitory computer-readable storage medium storing a program for causing a computer

A driving support method for a vehicle,

• the driving support method being executed by a driving support device for a vehicle,
• the driving support device including a direction indicator for indicating a travel direction of the vehicle, and being configured to decelerate the vehicle without a driver operating a brake pedal,
• the driving support method comprising:
• executing automatic deceleration control for decelerating the vehicle when a specific condition indicating that the driver of the vehicle intends to turn the vehicle to right or left at an intersection present in front of the vehicle is satisfied, the specific condition including operation of the direction indicator as a condition of satisfaction;
• continuing, when the direction indicator stops operating during execution of the automatic deceleration control, the automatic deceleration control for a predetermined time period from a time point at which the direction indicator stops operating;
• and
• ending the automatic deceleration control when the direction indicator continues to stop operating from the time point at which the direction indicator stops operating until the predetermined time period elapses.

A non-transitory computer-readable storage medium storing a program for causing a computer of a driving support device for a vehicle, the driving support device for a vehicle including a direction indicator for indicating a travel direction of the vehicle and being configured to decelerate the vehicle without a driver operating a brake pedal, to execute processing comprising:

• executing automatic deceleration control for decelerating the vehicle when a specific condition indicating that the driver of the vehicle intends to turn the vehicle to right or left at an intersection present in front of the vehicle is satisfied, the specific condition including operation of the direction indicator as a condition of satisfaction;
• continuing, when the direction indicator stops operating during execution of the automatic deceleration control, the automatic deceleration control for a predetermined time period from a time point at which the direction indicator stops operating;
• and
• ending the automatic deceleration control when the direction indicator continues to stop operating from the time point at which the direction indicator stops operating until the predetermined time period elapses.
