  • Publication number: 20180043792
    Abstract: A control device for electric motor vehicle using the motor as the traveling driving source and configured to decelerate by a regenerative braking force from the motor detects the accelerator operation amount, calculates the disturbance torque estimated value, and detects or estimates the resistance component unrelated to the gradient from the vehicle state. The control device for electric motor vehicle corrects the disturbance torque estimated value according to the detected or estimated resistance component unrelated to the gradient. The motor is controlled on the basis of the motor torque command value. When the accelerator operation amount is equal to or less than the predetermined value and the electric motor vehicle is just before the stop of the vehicle, the motor torque command value converges to the corrected disturbance torque estimated value in conjunction with the reduction of the rotation speed of the motor.

  • Patent number: 9845022
    Abstract: A control device for electric motor vehicle configured to decelerate by a regenerative braking force of the motor detects an accelerator operation amount, calculates a motor torque command value and controls the motor on the basis of the calculated motor torque command value. Further, a speed parameter proportional to a traveling speed is detected, and a feedback torque for stopping the electric motor vehicle is calculated on the basis of the detected speed parameter. Furthermore, the speed parameter is estimated in accordance with a state of the electric motor vehicle, and a feedforward torque is calculated on the basis of the estimated speed parameter. When accelerator operation amount is not larger than a predetermined value and the electric motor vehicle stops shortly, the motor torque command value is converged to zero on the basis of the feedback torque and the feedforward torque with a reduction in the traveling speed.

  • Publication number: 20160297303
    Abstract: A control device for electric motor vehicle is configured to decelerate by a regenerative braking force of the motor when an accelerator operation amount decreases or becomes zero. The control device detects the accelerator operation amount, calculates a motor torque command value, and controls the motor on the basis of the motor torque command value calculated. The control device detects a speed parameter proportional to a traveling speed and calculates a feedback torque for stopping the vehicle on the basis of the speed parameter detected. The control device also estimates a disturbance torque acting on the motor and converges, as the speed parameter is reduced, the motor torque command value to the disturbance torque on the basis of the feedback torque when the accelerator operation amount decreases or becomes zero and the electric motor vehicle stops shortly. The control device adjusts the feedback torque according to the disturbance torque.
