  According to the present invention, the energy of motion for eliminating the lack of motion of the occupant is converted into electric energy and used for driving the equipment of the traveling / operating system of the vehicle.

  An automobile equipped with a pedal pedal type accelerator device on the floor surface of a driver's seat is known in order to solve the lack of movement of the driver when driving the automobile for a long time (Patent Document 1). In this accelerator device, the driving force of the automobile is controlled in accordance with the momentum of the driver pedaling.

JP 2008-7054 A

  The kinetic energy generated by rowing the foot pedal type accelerator device is consumed by the opening / closing energy of the throttle valve and the like, and cannot be recovered and used as the energy of the drive source of the automobile. Therefore, even if it is beneficial for resolving the driver's lack of exercise, it is useless for replenishing the energy of the driving source of the automobile.

  Moreover, even if it helps to solve the lack of exercise for the driver, it does not help to solve the lack of exercise for other passengers. Further, there are problems such as overloading the driver during long-distance driving and difficulty in dealing with rapid acceleration for avoiding danger.

  In view of this, the present invention can be used for running / operation of an electric vehicle by providing a movement assist device of a system different from the driving system in the vehicle and recovering kinetic energy generated by operating the device as electric energy. Is an issue.

  In order to solve the above-described problems, the present invention is operated by an occupant's exercise assistance device and the exercise assistance device in an electric vehicle equipped with a main storage battery serving as a drive source for driving wheels and other parts of the vehicle. A configuration is adopted in which a generator and a storage battery for recovering the electric power obtained by the generator are provided, and the exercise assisting device is installed in the vicinity of a passenger's seat.

  When operating the electric vehicle, the occupant can solve the lack of exercise by operating the exercise assisting device as necessary to exercise. At the same time, the generator is rotated by the movement. The electric power generated by the rotation is stored in the recovery storage battery and used as electric power necessary for driving the automobile.

  As the above-mentioned recovery storage battery, an operation storage battery that drives equipment (accelerator, steering, brake, air conditioner, etc.) for the operation system of the vehicle other than the wheel drive motor is generally used. May be used as the storage battery for recovery, and the recovered power may be stored in the main storage battery. Further, the recovered power may be stored in both the main storage battery and the operation storage battery.

  When the occupant appropriately operates the exercise assisting device installed near the occupant's seat, the lack of exercise of the occupant in the automobile can be solved. Equipped with a generator that is actuated by an exercise assistance device, it is possible to convert the kinetic energy of the occupant into electric energy, and by collecting the electric energy, driving the equipment of the vehicle running and operating system Etc. can be used.

  By collecting and storing kinetic energy as electric energy, for example, even in the case of running out of fuel, it is possible to travel to the nearest power station. In addition, self-power generation is possible and high efficiency makes it possible to extend the cruising distance.
