Problems solved by technology

[0004] However, such a technique can be easily applied to an automatic transmission using a shift map based on vehicle speed and accelerator opening, but when applied to a manual transmission, there is a possibility that active shift control is performed to a shift gear that does not match the driver's intention. question

Abstract

The present invention provides a shift control method for a motor-driven vehicle, comprising: in an incomplete meshing state, the step of sensing the position of a shift operating device operated by a driver; and based on the sensed position of the shift operating device, the step of calculating the operation gear ratio; the step of calculating the rotational speed of the target motor output shaft based on the operational gear ratio, the rotational speed of the target motor output shaft being the rotational speed of the motor output shaft for shifting to the target gear; and controlling the motor output shaft The speed of the step so that it tracks the calculated speed of the target motor output shaft.

Description

technical field [0001] The present invention relates to a shift control method and control system of a motor-driven vehicle, more specifically, to a control method and a control system for actively controlling the rotational speed of a motor output shaft during shift control of a motor-driven vehicle equipped with a manual transmission. Background technique [0002] Generally, to synchronize the input shaft speed and output shaft speed of the transmission, manual slip through clutch hydraulic control is utilized. However, the synchronous method using slip has problems in that the shift time becomes longer and the shift feeling changes depending on the traveling state. [0003] In order to solve such a problem, a technology has been developed that enables motor-driven vehicles to actively control the rotation speed of the output shaft of the motor to synchronize the speed of the input shaft and the output shaft of the transmission during shift control of the motor-driven vehi...
