Guidance device, guidance method, and guidance program

A guidance method for providing guidance regarding an operation amount of a brake pedal in a vehicle having a friction brake and a regenerative brake, the guidance method comprising:

• acquiring, with a controller, a current speed of the vehicle;
• calculating, with the controller, a regeneration upper limit operation amount, which is an upper limit value of the operation amount of the brake pedal when only the regenerative brake is operated, based on the current speed of the vehicle;
• acquiring, with the controller, a deceleration target speed;
• acquiring, with the controller, a deceleration target position;
• calculating, with the controller, a distance to the deceleration target position;
• calculating, with the controller, a deceleration required operation amount of the brake pedal required for reducing the current speed of the vehicle to the deceleration target speed at the deceleration target position based on the acquired current speed of the vehicle, the acquired deceleration target speed, and the calculated distance to the deceleration target position;
• acquiring, with the controller, an upper limit operation amount of the brake pedal that corresponds to an amount of braking when the brake pedal is depressed to a maximum extent;
• acquiring, with the controller, a current operation amount of the brake pedal;
• creating, with the controller:
• a current operation amount display section that shows the acquired current operation amount;
• a regeneration upper limit operation amount display section that shows the calculated regeneration upper limit operation amount;
• and a deceleration required operation amount display section that shows the calculated deceleration required amount;
• and causing, with the controller, the current operation amount display section, the regeneration upper limit operation amount display section, and the deceleration required operation amount display section to be simultaneously displayed on a display within a display area that represents the operation amount of the brake pedal and spans from a position that corresponds to a non-operation state of the brake pedal to a position that corresponds to the upper limit operation amount.

a non-transitory computer-readable medium storing a computer executable program usable to provide guidance regarding an operation amount of a brake pedal in a vehicle having a friction brake and a regenerative brake, the program comprising:

• instructions for acquiring a current speed of the vehicle;
• instructions for calculating a regeneration upper limit operation amount, which is an upper limit value of the operation amount of the brake pedal when only the regenerative brake is operated, based on the current speed of the vehicle;
• instructions for acquiring a deceleration target speed;
• instructions for acquiring a deceleration target position;
• instructions for calculating a distance to the deceleration target position;
• instructions for calculating a deceleration required operation amount of the brake pedal required for reducing the current speed of the vehicle to the deceleration target speed at the deceleration target position based on the acquired current speed of the vehicle, the acquired deceleration target speed, and the calculated distance to the deceleration target position;
• instructions for acquiring an upper limit operation amount of the brake pedal that corresponds to an amount of braking when the brake pedal is depressed to a maximum extent;
• acquiring a current operation amount of the brake pedal;
• creating:
• a current operation amount display section that shows the acquired current operation amount;
• a regeneration upper limit operation amount display section that shows the calculated regeneration upper limit operation amount;
• and a deceleration required operation amount display section that shows the calculated deceleration required amount;
• and instructions for causing the current operation amount display section, the regeneration upper limit operation amount display section, and the deceleration required operation amount display section to be simultaneously displayed on a display within a display area that represents the operation amount of the brake pedal and spans from a position that corresponds to a non-operation state of the brake pedal to a position that corresponds to the upper limit operation amount.
