US 2026/0167260 A1 · STEER-BY-WIRE SYSTEM

Abstract

A steer-by-wire system includes a first control unit including a first CAN communication unit disposed in an SFA and connected to a CAN communication line, a second control unit including a second CAN communication unit disposed in an RWA and connected to the CAN communication line, a steering angle sensor configured to measure an input of a steering wheel and connected to the first control unit through the CAN communication line, and an R-CAN communication line to which the steering angle sensor and a portion of the second control unit are connected. In particular, when a failure of the SFA is determined, the second control unit receives data from the steering angle sensor using the R-CAN communication line to perform steering input to a wheel of a vehicle.

Dependent claims

A steer-by-wire system comprising:

a first control unit comprising a first controller area network (CAN) communication unit disposed in a steering force actuator (SFA) and connected to a CAN communication line;
a second control unit comprising a second CAN communication unit disposed in a road wheel actuator (RWA) and connected to the CAN communication line;
a steering angle sensor configured to measure an input of a steering wheel and connected to the first control unit through the CAN communication line;
and
a redundant-CAN (R-CAN) communication line to which the steering angle sensor and the second control unit are connected,
wherein, when a failure of the SFA is determined, the second control unit is configured to communicate with the steering angle sensor using the R-CAN communication line and perform steering input to a wheel.
