<p><P>PROBLEM TO BE SOLVED: To provide a gear shift unit of a vehicle which can accurately detect rotational angles of shift motors or the like when shift-controlling a shift rod by using a motor. <P>SOLUTION: The gear shift unit of the vehicle for shifting the shift rod 32 of the gear shift unit by using the motor comprises: a rotation/linear-movement conversion mechanism 80 which converts rotational motion to reciprocating linear motion and shift-operates the shift rod 32; a driven gear 58 which transmits rotation to the rotation/linear-movement conversion mechanism 80; a pair of drive gears 61, 63 which are engaged with the driven gear 58, respectively, and different in reduction ratio with respect to the driven gear 58; a pair the of shift motors 60, 62 which are driven by controlling the number of revolutions of the pair of drive gears 61 so as to correspond to the different reduction ratios, and have Hall ICs 65, 66 therein which detect the number of revolutions; and a TCM 73 to which detection values of the Hall ICs 65, 66 of the pair of shift motors are inputted, and which detects a rotational angle of the rotation/linear-movement conversion mechanism 80 from a phase difference of the detection values. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
