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： An auxiliary power source device (40) includes a main power source-side path (LI), an auxiliary power source-side path (L2), a power source control circuit (70), an analog determination circuit (100) that is provided separately from the power source control circuit (70), and a power source switching circuit (110). The power source control circuit (70) controls switching between a conduction state and an interruption state on the main power source-side path (LI) and the auxiliary power source-side path (L2). The analog determination circuit (100) determines an occurrence of abnormality in the main power source (50) and generates a switching signal when the occurrence of the abnormality in the main power source (50) is determined. The power source switching circuit (110) switchs a power source for supplying power to a power supply target, from the main power source (50) to the auxiliary power source (60).
