Guidance device, guidance method, and guidance program
First Claim
1. a guidance device that provides guidance regarding an operation amount of a brake pedal in a vehicle having a friction brake and a regenerative brake, the guidance device comprising:
- a controller configured to;
acquire a current speed of the vehicle;
calculate 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;
acquire a deceleration target speed;
acquire a deceleration target position;
calculate a distance to the deceleration target position;
calculate 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;
acquire 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;
acquire a current operation amount of the brake pedal;
create;
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
cause 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.

Abstract
Guidance devices, methods, and programs acquire a current speed of a vehicle and calculate a regeneration upper limit operation amount of the regenerative brake based on the current speed of the vehicle. The devices, methods, and programs acquire a deceleration target speed, acquire a deceleration target position, calculate a distance to the deceleration target position, and calculate 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. The devices, methods, and programs communicate guidance regarding the operation amount of the brake pedal based on the calculated regeneration upper limit operation amount and the calculated deceleration required operation amount.
