ELECTRIC MOTOR-DRIVEN POWER STEERING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electric motor-driven power steering device assisting operation of steering without causing a time lag from the operation of steering by a driver. SOLUTION: In the case that steering torque T detected by a torque detection part is placed in the conventional dead band in the vicinity of 0, by giving a prescribed drive current to a motor to drive it, backlash existing in a transmitting mechanism and a steering mechanism can be absorbed.
