Vehicle driving assistance apparatus, vehicle driving assistance method, and computer-readable storage medium storing vehicle driving assistance program

A vehicle driving assistance method for executing a deceleration assistance control of autonomously applying a braking force to an own vehicle to decelerate the own vehicle, and a coasting control of causing the own vehicle to coast,

• wherein the vehicle driving assistance method comprises steps of:
• executing the coasting control when a predetermined coasting condition becomes satisfied in a situation where a deceleration target which creates a need to decelerate the own vehicle, is not detected;
• executing the deceleration assistance control when the deceleration target is detected in a situation where the predetermined coasting condition is not satisfied;
• and
• determining whether to execute the coasting control depending on driving operation information on a driving operation carried out by an operator of the own vehicle when the deceleration target is detected in a situation where the predetermined coasting condition is satisfied.

A non-transitory computer-readable storage medium storing a vehicle driving assistance program which executes a deceleration assistance control of autonomously applying a braking force to an own vehicle to decelerate the own vehicle and a coasting control of causing the own vehicle to coast,

• wherein the vehicle driving assistance program is configured to:
• execute the coasting control when a predetermined coasting condition becomes satisfied in a situation where a deceleration target which creates a need to decelerate the own vehicle, is not detected;
• execute the deceleration assistance control when the deceleration target is detected in a situation where the predetermined coasting condition is not satisfied;
• and
• determine whether to execute the coasting control depending on driving operation information on a driving operation carried out by an operator of the own vehicle when the deceleration target is detected in a situation where the predetermined coasting condition is satisfied.
