SHIFT SHOCK REDUCTION SYSTEM OF ELECTRICALLY DRIVEN UTILITY VEHICLE

摘要

A shift shock reduction system of an electrically driven utility vehicle comprises: a motor controller which controls an output of a motor; an automatic transmission which has a pair of electrically-powered means with two speeds or more; and a transmission control unit which is electrically connected with the controller, and controls the automatic transmission, wherein when the automatic transmission changes speed by the transmission control unit, a temporary neutral state is implemented, and as soon as the automatic transmission reaches a neutral position, control for increasing or reducing RPM of the motor can be carried out by the motor controller.

1. A shift shock reduction system for an electrically driven utility vehicle, comprising:
a motor controller controlling output of a motor; an automatic transmission having a pair of power transmitting means of two steps or more; and a shift controller connected to the motor controller so that the shift controller sends and receives control information to and from the motor controller and controlling a gear shift of the automatic transmission, wherein the automatic transmission is implemented to be placed in a temporary neutral state when a gear shifts under a control of the shift controller, and the motor controller performs control for increasing or decreasing rotation speed of the motor when the automatic transmission reaches the neutral state.
