Driver assistance apparatus, driver assistance method, and a non-transitory computer-readable storage medium storing a program

A driver assistance method comprising a step of executing either a coasting control or a deceleration control, when a predetermined deceleration condition for decelerating a host vehicle becomes satisfied, wherein

• said coasting control is a control for setting a connection state between a drive source of said host vehicle and drive wheels of said host vehicle to a power cutoff state in which power is not transmitted between said drive source and said drive wheels and for causing said vehicle to coast, and
• said deceleration control is a control for setting said connection state to a power transmission state in which power is transmitted between said drive source and said drive wheels and for causing said vehicle to decelerate by causing an external force input from said drive wheels to be transmitted to said drive source,
• and wherein
• said method further comprises:
• a step of obtaining information indicative of driving circumstances of said host vehicle;
• and
• a step of determining, based on said obtained information indicative of the driving circumstances of said host vehicle, which one of said coasting control and said deceleration control is to be executed.

A non-transitory computer-readable storage medium storing a program, said program comprising instructions which, when executed by a processor of a controller mounted on a host vehicle, cause the processor to perform a step of executing either a coasting control or a deceleration control, when a predetermined deceleration condition for decelerating a host vehicle becomes satisfied, wherein

• said coasting control is a control for setting a connection state between a drive source of said host vehicle and drive wheels of said host vehicle to a power cutoff state in which power is not transmitted between said drive source and said drive wheels and for causing said vehicle to coast;
• and
• said deceleration control is a control for setting said connection state to a power transmission state in which power is transmitted between said drive source and said drive wheels and for causing said vehicle to decelerate by causing an external force input from said drive wheels to be transmitted to said drive source,
• and wherein
• said instructions which, when executed by said processor, cause the processor to perform:
• a step of obtaining information indicative of driving circumstances of said host vehicle;
• and
• a step of determining, based on said obtained information indicative of the driving circumstances of said host vehicle, which one of said coasting control and said deceleration control is to be executed.
