Title: ELECTRIC VEHICLE CONTROL METHOD AND CONTROL DEVICE
Abstract:
A control method for an electric vehicle comprising a motor that provides braking force or drive force to the vehicle, in accordance with the amount of accelerator operation. The electric vehicle control method controls braking force when the accelerator operation amount is less than a prescribed value and controls drive force when the accelerator operation amount is at least a prescribed value. The electric vehicle control method: estimates disturbance torque that acts on the motor as a resistance component relating to gradient; and executes correction whereby the braking force or the drive force is increased/decreased in accordance with the external disturbance torque estimated value, so as to negate the resistance component. On downhill roads having at least a prescribed gradient, the correction amount for the braking force or drive force is reduced.
