Abstract
A control device of an electric car in which any two of control devices fixed to the corresponding electric motors send signals to each other and send and receive control information by taking a bypass route when any one of transmission lines malfunctions is provided. Fail safe means for signal transmission lines, in which a bypass route is established such that a node detecting a communication failure in an electronic control system of the car sends a search message for searching a transmission route and another node which is able to establish the transmission route sends back a response message, is provided.
