Abstract
Provided is a control system capable of reducing cost while securing reliability of original processing of a microcomputer. An engine control device and a meter control device each store a control amount calculating procedure for calculating a control amount regarding a significant control to be performed on the control target of the engine control device. The engine control device compares a control amount regarding the significant control calculated by the engine control device, and a control amount regarding the significant control calculated by the meter control device, to thereby control the control target of the engine control device based on a result of the comparison.
Claims21
A control system, comprising a plurality of control devices for controlling different control targets, respectively, the plurality of control devices each being connected to a network in which time synchronization is possible between nodes connected thereto, the plurality of control devices comprising a first control device and a second control device and subsequent control devices, wherein:
- the first control device and the second control device and the subsequent control devices each store a control amount calculating procedure for calculating a control amount regarding a significant control having a higher degree of significance among controls to be performed on the control target of the first control device;
- and
- the first control device compares a control amount regarding the significant control, which is calculated by the first control device, and a control amount regarding the significant control, which is calculated, after synchronization with the first control device, by one of the second control device and the subsequent control devices, to thereby control the control target of the first control device based on a result of the comparison.
