PURPOSE: A digital handle with a hall effect encoder module for a four-wheel drive electric vehicle is provided accomplish more precise cornering by rapidly controlling the rotation speed and direction of a front wheel. CONSTITUTION: A hall effect encoder module(100) is installed on the lower end of a handle of a four-wheel-drive electric vehicle. The hall effect encoder module outputs a Zero-axis return check signal to a four-wheel-drive motor control module. The four-wheel-drive motor control module outputs a rotation speed signal and a rotation direction signal. A hall effect encoder(110) transmits a digital signal of a B channel to a first buffer(130). A handle direction setting unit(120) transmits a clock pulse signal to the first buffer. [Reference numerals] (110) Hall effect encoder; (120) Handle direction setting unit; (130) First buffer; (140) Synchronous BCD up/down counter for turning left; (150) Synchronous BCD up/down counter for turning right; (160) Second buffer; (170) Third buffer; (180) First connector; (190) Second connector |
