  • Apparatus for implementing interlock of electric power steering system
    Patent number: 8165757
    Abstract: An apparatus for implementing interlock of an electric power steering system is disclosed. The interlock apparatus can generate the output torque current value for achieving the steering system interlock with current values of two phases and the rectifying positional value for the 1-bit feedback current of one phase out of the 3-phase feedback current values and the rectifying positional value for the 3-bit 3-phase feedback current values. The disclosed interlock apparatus receives the 3-phase feedback current values from the current sensor and the rectifying positional values for the 3-bit 3-phase feedback current values from the rectifying positional sensor, and retrieves therefrom the current values of two phases and the rectifying positional value for the 1-bit feedback current of one phase for use with a substantially cost effective processor in generating the output torque current value.
