Abstract
A system and a method for controlling an electrically-powered steering apparatus of a vehicle may include a selection switch adapted to select any of a plurality of steering modes, a control switch adapted to change a current for controlling the steering force, a control portion adapted to determine the current according to a signal received from at least one of the selection switch and the control switch and to transmit a control signal according to the determined current, and a drive portion adapted to control the steering force according to the control signal received from the control portion.
Claims9
A system for controlling an electrically-powered steering apparatus comprising:
- a selection switch adapted to select any of a plurality of steering modes;
- a control switch adapted to change a current for controlling the steering force;
- a control portion adapted to determine the current according to a signal received from at least one of the selection switch and the control switch and to transmit a control signal according to the determined current;
- and
- a drive portion adapted to control the steering force according to the control signal received from the control portion,
- wherein the control switch comprises:
- a change switch adapted to change the current determined at the selected steering mode;
- and
- a return switch adapted to recover the current changed by the change switch to the current determined at the steering mode selected by the selection switch.
A method for controlling an electrically-powered steering apparatus that controls a steering force according to a current, comprising:
- receiving a mode signal corresponding to a steering mode selected from a plurality of steering modes by a user;
- receiving a change signal for changing the steering force at the selected steering mode into a steering force desired by the user;
- determining, if at least one of the mode signal and the change signal is received, a first current corresponding to the steering force at the selected steering mode based on the received mode signal or a second current of the steering force desired by the user based on the received change signal;
- transmitting a control signal corresponding to the determined first and second currents;
- and
- receiving a return signal from a return switch for recovering the steering force desired by the user to the steering force at the selected steering mode of the mode signal;
- determining the first current corresponding to the steering force at the selected steering mode selected according to the return signal of the return switch;
- and
- controlling the steering force according to the control signal.
