Abstract
A motor control device drives a motor based on a vehicle signal including drive assist information and performs vehicle control. The motor control device includes: a first controller and a second controller that perform a calculation operation concerning drive control over the motor. A first microcomputer corresponds to a calculation portion of the first controller. A second microcomputer corresponds to a calculation portion of the second controller. The first microcomputer and the second microcomputer mutually transmit and receive operation results by inter-microcomputer communication, or the first microcomputer unilaterally transmits an operation result from the first microcomputer by the inter-microcomputer communication. The first microcomputer and the second microcomputer synchronize timings to start and end control by performing at least one of three types of arbitration processes including: an AND-start arbitration process; an OR-start arbitration process; and a forced arbitration process.
