Title: Vehicular electronic control device
Inventor: NAKAMURA MICHIO
IPC: F16H59/72
Filed: 2000-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a vehicular electronic control device capable of realizing a CSMA/CD type inter-vehicle communication system capable of smoothly carried out communication between control devices by appropriately reducing a bus load (a data duty factor on a communication line). SOLUTION: In an ECU (an electronic control device) for forming an inter- vehicle communication system of the CSMA/CD type, a control data calculated by a self is sent to a communication line regularly, and is provided to the other ECU. A transmission interval between the control data is changed according to an operating condition of the vehicle. For example, in a water temperature data for indicating the cooling water temperature of an engine, a time t after starting the engine (a lapsed time after the engine is started) is measured (S110), an interval for sending the water temperature data is set to a time longer toward the time t is longer (S120 to S180). It is thus possible to reduce a bus load in the whole of a system and a treating load in the ECU.
