Abstract
There is provided an actuator control apparatus configured such that even when an electronic device that generates an electric signal to be used to control an actuator is provided in the form of a duplexed system, an increase in the number of communication paths between the electronic device and a controller is suppressed. A torque sensor and a rotation angle sensor are each provided in the form of a duplexed system. Two sets of a torque sensor and a rotation angle sensor are connected to a microcomputer via a SPI communication line. The torque sensors and the rotation angle sensors are connected to the microcomputer via CS communication lines, respectively. By selecting a communication target via a corresponding one of the CS communication lines, the microcomputer is able to receive multiple kinds of electric signals via each one of the SPI communication lines.
