Embodiment Construction

[0034] Referring to the accompanying drawings, preferred embodiments of a control device and a control system according to an embodiment of the present invention will be described below.

[0035]figure 1 Shown is a schematic block diagram of a basic vehicle control system according to this embodiment.

[0036] exist figure 1 In, reference numeral 10 denotes a vehicle control system. The vehicle control system includes: a first electronic control unit (hereinafter ECU) 20 for engine control; a second ECU 30 for air bag control; a third ECU 40 for ABS control; Take device 50.

[0037] Since the structures of the ECUs 20, 30 and 40 are almost identical, a schematic configuration of the first ECU 20 will be given below.

[0038] The first ECU 20 includes: a communication circuit section 21, which is a communication device for controlling data communication with other ECUs 30 and ECU 40; a microcomputer, used for controlling each part of the first ECU 20; and a nonvolatile memor...

Abstract

A control apparatus includes a communication unit for conducting the data communication. Identification information is assigned to the control apparatus. The control apparatus further includes a storage unit having an identification information table storing information containing the identification information and the identification information of other control apparatuses, which are connected to and communicate with the control apparatus.

Description

[0001] The subject matter related to the present invention is contained in Japanese Patent Application No. 2002-203358 filed Jul. 12, 2002, which is incorporated herein by reference in its entirety. technical field [0002] The present invention relates to a control device and a control system, more particularly to a control device with a communication device for data communication and a control system comprising a plurality of control devices connected to each other for mutual communication . Background technique [0003] In recent years, different control devices have been installed on vehicles, including engine control devices for controlling engine fuel injection or ignition timing, ABS control devices for controlling anti-lock braking system (ABS), and air bag control devices. Deploy the airbag control unit for operation. [0004] In addition, there is a control system equipped with a so-called vehicle local area network (LAN), in which these control devices are connec...
