Patent number: 11878592Abstract: A control method for an electric vehicle 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 on the basis of the disturbance torque estimated value, such that the resistance component is negated. A determination is made regarding whether or not the accelerator operation amount is a partial equivalent amount and, if at least either the accelerator operation amount on a downhill road is greater than the partial equivalent amount or the accelerator operation amount on an uphill road is less than the partial equivalent amount, the correction amount is reduced.Type: GrantFiled: January 24, 2017Date of Patent: January 23, 2024Assignee: Nissan Motor Co., Ltd.Inventors: Naoteru Kujubu, Ikuma Shindo, Tatsuya Suzuki
