Title:
METHOD FOR CONTROLLING ELECTRICALLY DRIVEN VEHICLE AND DEVICE FOR CONTROLLING ELECTRICALLY DRIVEN VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/139375
Kind Code:
A1
Abstract:
The present invention is a method for controlling an electrically driven vehicle provided with a motor that supplies the vehicle with a braking force or a driving force according to the amount of accelerator operation, wherein the braking force is controlled when the amount of accelerator operation is less than a prescribed value, and the driving force is controlled when the amount of accelerator operation is equal to or more than the prescribed value. A torque target value at which the motor is made to output a braking/driving torque according to the amount of accelerator operation is calculated. A disturbance torque acting on the motor as a resistance corresponding to a road surface gradient is estimated. Correction for eliminating the disturbance torque from the torque target value is performed. The motor is controlled according to the corrected torque target value. Then, when the amount of accelerator operation is less than the prescribed value and the vehicle speed is more than a prescribed vehicle speed on a downhill road, the amount of correction in said correction is reduced.
