1. A control apparatus for a vehicle comprising:
- a plurality of actuators configured to perform sprung vibration suppression control by suppressing a bounce movement, a pitch movement and a roll movement of a vehicle body,a vertical acceleration sensor configured to detect a sprung vertical acceleration, anda plurality of actuator attitude control units configured to control the respective actuators such that the vertical acceleration detected by the vertical acceleration sensor becomes a vertical acceleration corresponding to a target sprung state, whereinthe plurality of actuators are a driving power source, a friction brake, and a damping force variable shock absorber of the vehicle, andthe plurality of actuator attitude control units are a driving power source attitude control unit, a friction brake attitude control unit, and a damping force control unit, andthe driving power source attitude control unit suppresses only the bounce movement and the pitch movement, andthe damping force control unit suppresses only the roll movement, a control of the driving power source, a control of the friction brake, and a control of the damping force variable shock absorber are performed in parallel to suppress a damping force control amount of the damping force variable shock absorber.
