摘要： The present invention provides a control apparatus for an electric vehicle that can prevent a vehicle from losing the stability because a rear wheel is locked first or prevent the drivability from reducing because a front wheel is locked early. A control apparatus outputs an instruction to generate a first regenerative braking force corresponding to a regenerative braking force on an electric motor when a signal regarding a return of a pressed accelerator pedal is input from an accelerator pedal sensor. The accelerator pedal sensor is configured to detect a physical amount regarding a stroke of the accelerator pedal of the electric vehicle. The control apparatus outputs an instruction to generate a brake actuation braking force on a wheel when a signal regarding pressing of a brake pedal is input from a brake pedal sensor. The brake pedal sensor is configured to detect a physical amount regarding a stroke of the brake pedal of the electric vehicle. The control apparatus outputs, to the electric motor, an instruction to reduce a total value of the first regenerative braking force and the brake actuation braking force by a braking force corresponding to a second regenerative braking force, which is a regenerative braking force smaller than the first regenerative braking force, when an output value lower than a predetermined speed is input from a vehicle body speed detection sensor. The vehicle body speed detection sensor is configured to detect a physical amount regarding a vehicle body speed of the electric vehicle.

摘要： 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.
