Abstract

The invention provides a control method for virtual gear shift feeling generation of an electric vehicle. The control method includes generating and realizing a virtual sensation of gear shifting the same as that of a vehicle equipped with a multi-speed transmission, in the electric vehicle without a multi-speed transmission. In particular, virtual gear shift intervention torque and limit torque for each virtual gear shift stage are determined from input variables through a virtual gear shift model by inputting vehicle driving information collected from a vehicle during operation. Then the determined virtual shift intervention torque, the determined limit torque for each virtual shift stage, and motor torque command are applied to operate a motor, thereby realizing the virtual sensation of multi-speed gear shifting.

Description

technical field [0001] The present invention relates to a control method of an electric vehicle, and more particularly, to a control method of an electric vehicle capable of generating and realizing, in an electric vehicle without a multi-speed transmission, the same shifting feeling as that of a vehicle equipped with a multi-speed transmission . Background technique [0002] As is well known, an electric vehicle (EV) is a vehicle driven using a motor as a driving force source for driving the vehicle. The power train of an electric vehicle includes a battery, an inverter, a motor and a reduction gear, the battery supplies electric power to drive the motor, the inverter is connected to the battery to drive and control the motor, which serves as the drive source of the vehicle through The inverter is connected to the battery so as to charge and discharge, and the reduction gear reduces the rotational force of the motor and transmits the rotational force to the driving wheels....
