Abstract

A method of controlling traveling of an electric vehicle is provided. The method includes generating a motor torque command using a basic torque command and a virtual gear-shift intervention torque for generating a feeling of real gear shifting, while an electric vehicle travels. A motor is operated for driving the electric vehicle according to the generated motor torque command to generate the feeling thereof. In generating the feeling thereof, during at least a portion of time during which the feeling thereof is generated, boost control of the motor operation is performed such that a motor torque exceeding an allowable torque of the motor is generated, and thus the generation of the feeling thereof and the boost control are performed in conjunction with each other.

Description

technical field [0001] The present invention relates to a driving control method of an electric vehicle, more particularly to an enhanced application control strategy and a driving control method of an electric vehicle using the enhanced application control strategy, and the enhanced application control strategy can improve the driving of the electric vehicle Performance can also improve its acceleration performance. Background technique [0002] Electric vehicles (EVs) are known to use one or more electric motors for propulsion. A driving system of an electric vehicle includes: an electric motor serving as a driving force source; a battery for supplying electric energy to the electric motor; an inverter for driving the electric motor; A small rotational force is transmitted to the drive wheels. The electric motor is connected to the battery via an inverter to charge or discharge the battery according to the operating mode of the electric motor. [0003] During the drivin...
