Control method for electric vehicle and control device for electric vehicle

Abstract

To provide an electric-vehicular control method and an electric-vehicular control apparatus, which are capable of realizing desired acceleration while suppressing a pitching vibration.SOLUTION: A control method computes a first front-wheel drive force instruction value Ff1* that determines drive force of a front wheel 14 and a first rear wheel drive force instruction value Fr1* that determines drive force of a rear wheel 16 on the basis of target drive force for an electric vehicle 1, and computes a norm value of a pitch angular velocity λ' or a pitch angle λ on the basis of the first front-wheel drive force instruction value Ff1* and the first rear wheel drive force instruction value Fr1*. Meanwhile, a detection value of the pitch angular velocity λ' or pitch angle λ is acquired. Further, the control method computes, on the basis of a difference between the detection value and the norm value of the pitch angular velocity λ' or the pitch angle λ, a drive force movement amount Td that represents a magnitude of drive force for moving between the front wheel 14 and the rear wheel 16 in order to suppress a pitching vibration, and corrects the first front-wheel drive force instruction value Ff1* and the first rear wheel drive force instruction value Fr1* on the basis of the drive force movement amount Td.SELECTED DRAWING: Figure 6
