Patent number: 11027617Abstract: An electrically driven vehicle includes a motor configured to supply the vehicle with a braking force or a driving force corresponding to an accelerator operation amount. The braking force is controlled when the accelerator operation amount is less than a predetermined value and the driving force is controlled when the accelerator operation amount is the predetermined value or more. A torque target value at which the motor is caused to output a braking or driving torque corresponding to the accelerator operation amount is calculated. A disturbance torque acting on the motor as a resistance corresponding to a road surface gradient is estimated, and a correction to remove the disturbance torque from the torque target value is performed. The correction amount is reduced in a downhill road when the accelerator operation amount is less than the predetermined value and a vehicle speed is larger than a predetermined vehicle speed.Type: GrantFiled: January 19, 2018Date of Patent: June 8, 2021Assignee: NISSAN MOTOR CO., LTD.Inventors: Ikuma Shindo, Tatsuya Suzuki, Naoki Miyashita
