Actuator control apparatus

摘要

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.

1. An actuator control apparatus comprising:
a first electronic device that generates an electric signal to be used to control an actuator; a second electronic device that has a function different from a function of the first electronic device, and that generates an electric signal to be used to control the actuator; a third electronic device that has the same function as the function of the second electronic device, and that generates an electric signal to be used to control the actuator; a fourth electronic device that has the same function as the function of the first electronic device, and that generates an electric signal to be used to control the actuator; a controller that controls the actuator based on the electric signals generated by the first to fourth electronic devices; a first serial bus that connects the first and second electronic devices to the controller; and a second serial bus that connects the third and fourth electronic devices to the controller.
