Abstract
Provided is a control apparatus, a control method, and a control system for an electric vehicle that can prevent or reduce an unnecessary torque fluctuation on a wheel not targeted for slip control. A control apparatus for an electric vehicle limits a torque to be output to a non-target wheel according to a torque output to a target wheel after target wheel slip control is started, and updates a limit value of the torque to be output to the non-target wheel when a fluctuation range of the torque output to the target wheel falls within a predetermined range during the limitation.
