CONTROLLER FOR ELECTRIC AUTOMOBILE

摘要

A controller for electric automobile by which a signal can be transmitted even among controllers fixed to respective motors and control information can be transmitted/received by detouring upon occurrence of a trouble on any one transmission line. In the electronic control system of an electric automobile, a fail-safe means of a signal transmission path is provided such that a node detecting a communication trouble transmits a search message for searching a transmission path and a node which can form a transmission path sends back a response message thus forming a detouring circuit.
