Vehicle control apparatus, vehicle control method, and vehicle control system

A vehicle control apparatus including a control unit that outputs a result obtained by an operation based on input information, wherein the control unit is configured to acquire occupant specifications including a mass of an occupant in a vehicle and position of center of gravity of the occupant, acquire a physical quantity about a pitch angle of the vehicle, acquire a physical quantity about an acceleration of the vehicle, and output a control command for activating an actuator unit that controls the pitch angle of the vehicle based on a physical quantity about an occupant pitch moment, with the occupant pitch moment being calculated based on the occupant specifications, the physical quantity about the pitch angle, and the physical quantity about the acceleration, and the occupant pitch moment being applied to the occupant by a force that the occupant receives from a behavior of the vehicle, wherein the actuator unit is an active suspension, and

• wherein the control unit acquires a physical quantity about a suspension stroke of the active suspension, calculates a suspension stroke difference, which is a difference between the acquired suspension stroke and a reference suspension stroke obtained by conversion of a reference pitch angle of the vehicle, the reference pitch angle being calculated based on the occupant pitch moment and being a pitch angle in a direction opposite to the pitch angle of the vehicle, and outputs a control command for activating the active suspension such that the suspension stroke difference is reduced.
