    摘要： A control method of an electric vehicle using one or a plurality of motors as a traveling drive source, includes: a motor torque command value calculating step that calculates a motor torque command value; an angular velocity detecting step that detects an angular velocity correlating with a rotation speed of a drive shaft which transmits a drive force of the motor to a drive wheel; a disturbance torque estimating step that estimates a disturbance torque acting on the motor based on the motor torque command value and the angular velocity; a limiting torque setting step that sets a limiting torque corresponding to the disturbance torque in a manner that a slipping rate of the drive wheel does not exceed a first predetermined value; and a motor torque limiting step that limits the motor torque command value using the limiting torque.

    摘要： A control method for an electric vehicle using a motor as a traveling drive source to decelerate by a regenerative braking force of the motor, including: obtaining an accelerator operation amount; estimating a disturbance torque acting on a vehicle body of the electric vehicle; obtaining an angular velocity of a rotating body that correlates to a rotation speed of a drive shaft which drives the electric vehicle; calculating a first torque command value based on the accelerator operation amount; setting the first torque command value to a torque command value; controlling a torque generated in the motor based on the torque command value; setting a target stop position at the time of stopping the electric vehicle; calculating a target angular velocity of the rotating body according to a distance from the electric vehicle to the target stop position; calculating a second torque command value for stopping the electric vehicle at the target stop position based on a difference between the target angular velocity and the obtained angular velocity; and converging the torque command value to the disturbance torque by setting the second torque command value to the torque command value and adjusting the braking and driving forces of the motor according to a distance to the target stop position, when the accelerator operation amount decreases or becomes zero and the electric vehicle is about to stop.

    摘要： 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.
