GEAR-SHIFT CONTROL METHOD FOR VEHICLE MOTOR-DRIVING APPARATUS, AND GEAR-SHIFT CONTROL METHOD FOR VEHICLE

WIPO Patent Application WO/2012/165146

A1

The present invention minimizes the time necessary for shifting gears in a vehicle motor-driving apparatus that uses a two-way roller clutch, and reduces shift shocks. A gear-shift control method for a vehicle motor-driving apparatus comprises: a first step (S1) wherein a gear-shift command is outputted; a second step (S2) wherein a shift ring (34) is moved from a first-gear shift position (SP1f) to a second-gear shift position (SP2f); a third step (S3) wherein the output of an electric motor (3) is controlled so as to release the engagement of a two-way roller clutch (16A) of the first gear; a fourth step (S4) wherein synchronous operation is executed using rotational-speed control; and a fifth step (S5) wherein the output control of the electric motor (3) is switched from the rotational-speed control to a torque control, and the output torque of the electric motor (3) is gradually raised with the torque control.
