VEHICLE DRIVEN BY ELECTRIC MOTOR AND CONTROL METHOD FOR VEHICLE
DRIVE
May 18, 2016
A vehicle driven by an electric motor (136), includes: an accelerator operation amount detection unit (175); a speed detection unit (139); and a control unit (180) configured to calculate a required torque (T RQ ) of the electric motor on a basis of a accelerator operation amount and a vehicle speed, calculate a torque increase rate (RA Tp ), which is a required rate at which an effective torque (T AC ) for driving the electric motor is increased, on a basis of the required torque, and control the electric motor on a basis of the calculated torque increase rate. The control unit is configured to control the electric motor to operate at a predetermined torque increase rate until the effective torque reaches a predetermined threshold torque (T CHG ), and to reduce the torque increase rate below the predetermined torque increase rate after the effective torque reaches the predetermined threshold torque.
