摘要： An actuator (10) that applies force to a member associated with steering, and a control device (100) that controls the actuator, have duplex configuration. First and second control devices (100-1, 100-2) compute the same controlled variable as first and second controlled variables (C1, C2), respectively. In a normal mode, the control device (100) controls the actuator according to the first controlled variable (C1). When a discrepancy arises between the first and second controlled variables (C1, C2), or an abnormality occurs in communications between the first and second control devices (100-1, 100-2), the operating mode is switched from the normal mode to an independent mode. In the independent mode, the first and second control devices (100-1, 100-2) control the first and second actuators, according to the first and second controlled variables (C1, C2), respectively.

摘要： A steer-by-wire steering system, including: a two-system reaction force applying device (62) including two reaction force controllers (110A, 110B) and configured to obtain operation information and apply an operation reaction force; a two-system steering device (64) including two steering controllers (108A, 108B) and configured to steer a wheel (12); an operation information obtaining device (106, 112); an auxiliary steering device (52) capable of changing a direction of a vehicle; two dedicated communication lines (124A, 124B) one of which information-transmittably and information-receivably connects one of the two reaction force controllers (110A, 110B) and one of the two steering controllers (108A, 108B) to each other, and the other of which information-transmittably and information-receivably connects the other of the two reaction force controllers (110A, 110B) and the other of the two steering controllers (108A, 108B) to each other; and a first communication bus (120a) to which the operation information obtaining device (106, 112) is at least information-transmittably connected and to which the two steering controllers (108A, 108B) and the auxiliary steering device (52) are at least information-receivably connected.
