Vehicle information calculation apparatus, vehicle information calculation method, and vehicle control apparatus

A vehicle information calculation method comprising:

• acquiring a torque of a motor that drives a vehicle;
• acquiring an angular acceleration of the motor;
• acquiring a contact force of a wheel of the vehicle;
• and
• calculating an inertia moment of a rotating system of the vehicle including the wheel on a basis of the torque, the angular acceleration, the contact force, and a coefficient of friction between the wheel of the vehicle and a contact surface.

A vehicle control apparatus to be provided in a vehicle including a motor as a drive source, the vehicle control apparatus comprising:

• a storage including an inertia moment of a rotating system stored therein, the rotating system including a wheel to be driven by the motor;
• and
• a controller configured to control behavior of the vehicle on a basis of the inertia moment stored in the storage,
• the inertia moment having a value calculated on a basis of a torque of the motor, an angular acceleration of the motor, a contact force of the wheel, and a coefficient of friction between the wheel and a contact surface.
