Title:
ELECTRIC VEHICLE CONTROL DEVICE AND ELECTRIC VEHICLE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2015/083213
Kind Code:
A1
Abstract:
A control device is used in an electric vehicle that uses a motor as a traveling drive source and is decelerated by the 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, according to the calculated motor torque command value. The control device detects a speed parameter proportional to the traveling speed of the electric vehicle and calculates a feedback torque for stopping the electric vehicle, according to the detected speed parameter. The control device then estimates a disturbance torque acting on the motor and, when the accelerator operation amount decreases or becomes zero and the electric vehicle is about to stop, converges the motor torque command value to the disturbance torque according to the feedback torque, together with the reduction of the speed parameter. The control device also adjusts the feedback torque in accordance with the disturbance torque.
