Systems and methods for an optimized steer-by-wire architecture with limited feedback content

A method for controlling vehicle steering, the method comprising:

• generating, using a first electronic control unit, a feedback torque, using a feedback torque mechanism, in response to a steering input;
• supplying power, using a first power supply, to the first electronic control unit;
• controlling, using a second electronic control unit, at least one vehicle wheel based on the feedback torque and the steering input;
• supplying power, using a second power supply, to the second electronic control unit;
• determining whether the second power supply has failed;
• and
• in response to a determination that the second power supply has failed, instructing the first electronic control unit to communicate the steering input and the feedback torque to the second electronic control unit, wherein the second electronic control unit receives power from the first power supply in response to the determination that the second power supply has failed.

An apparatus for controlling vehicle steering, the apparatus comprising:

• a processor;
• and
• a memory including instructions that, when executed by the processor, cause the processor to:
• generate, using a first electronic control unit, a feedback torque, using a feedback torque mechanism, in response to a steering input;
• supply power, using a first power supply, to the first electronic control unit;
• control, using a second electronic control unit, at least one vehicle wheel based on the feedback torque and the steering input;
• supply power, using a second power supply, to the second electronic control unit;
• determine whether the second power supply has failed;
• and
• in response to a determination that one of the first power supply and the second power supply has failed, instruct the first electronic control unit to communicate the steering input and the feedback torque to the second electronic control unit, wherein the second electronic control unit receives power from the first power supply in response to the determination that the second power supply has failed.
