とされている。As one of such techniques, for example, in an electric railway, a vehicle is braked by a resistance generated by operating a motor as a generator during vehicle deceleration, and
Regenerative braking is performed in which the generated power is sent back from the trolley wire and supplied to other trains. That is, in this method,
It is assumed that a part of the kinetic energy of the vehicle released during deceleration (excluding energy lost due to friction and the like, hereinafter referred to as regenerative energy) is converted into electric energy and used.

される。Further, in various types of vehicles, in which regenerative energy is stored as mechanical energy, deceleration energy is stored by a system consisting of a flywheel and a continuously variable transmission and is utilized at the time of starting. Regenerative braking devices are known (see Japanese Patent Publication No. 55-6785 and Japanese Patent Publication No. 57-127154). In this case, the regenerative energy transmitted from the wheels to the flywheel via the continuously variable transmission is accumulated as the rotational energy of the flywheel and is used for acceleration such as when the vehicle starts.

ギを十分に活用できないという問題がある。Thus, conventionally, regenerative braking has been performed in which the deceleration energy of the vehicle is used for reacceleration.
However, the conventional regenerative braking method used in the above-mentioned electric railway has a problem in that the mechanical energy is converted into electric energy, so that the loss is large and therefore the regenerative energy cannot be fully utilized.

Each of the conventionally proposed regenerative braking methods has a problem in that the regenerative energy is simply stored in the flywheel, and the influence on the operational feel of the brake is not considered at all.
