MOTOR CONTROL SYSTEM, MOTOR CONTROL METHOD, AND MOTOR CONTROL DEVICE

摘要

A host controller is incorporated with a plurality of different pieces of control software which are applicable to a plurality of destinations for a cooling blower to cool a main battery incorporated in a vehicle. The host controller transmits a destination-signal request pattern for requesting a destination signal pattern to specify the determinations for the cooling blower, to a motor control device by means of a PWM signal. Upon receiving the destination-signal request pattern, the motor control device transmits the destination signal pattern to the host controller. The host controller specifies one of the destinations for the cooling blower from the received destination signal pattern, and then changes over the control software to the control software applicable to the specified destination for the cooling blower.

1. A motor control system, comprising:
a motor control device for controlling a motor of a cooling blower for cooling a battery incorporated in a vehicle; and a host controller including a plurality of different pieces of control software applicable to a plurality of destinations for the cooling blower, the host controller transmitting and receiving control information of the motor to and from the motor control device by means of a PWM signal, wherein the host controller transmits, to the motor control device by means of the PWM signal, a destination-signal request pattern for requesting a destination signal pattern to specify the destinations; the motor control device transmits the destination signal pattern to the host controller upon receiving the destination-signal request pattern; and the host controller specifies one of the destinations for the cooling blower from the destination signal pattern and changes over the control software to the control software applicable to the specified one of destinations for the cooling blower.
