Passive starting of a torque-ripple-free electric power steering system

摘要: A method for passively starting an electric power steering (“EPS”) system includes disabling assist torque upon power-up, detecting index pulse a movement of column across one plurality reference positions, enabling the EPS pulse, receiving variable input command indicative external input, and ramping motor towards after until is substantially equal to command; wherein apparatus wheel operator inputs coupled column, applying encoder determining angular displacement where comprises at least track set sensors sensing generate signals, controller connected in signal communication between signals from controlling correspondence with system, comprising detector, enabler responsive detector amplifier, amplifier command.
