Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/012927
Kind Code:
A1
Abstract:
The purpose of the present invention is to prevent a communication device from transmitting data to a communication network when an arithmetic device is operating abnormally, even in the case of an electronic control device that uses a communication device not equipped with a terminal for receiving input of a signal for switching to a receive-only mode. In this electronic control device, a communication device is configured not to transmit a signal to a communication network while a signal of a predetermined signal level is being received from an arithmetic device, and a monitoring device overwrites a signal output by the arithmetic device with the signal of the predetermined signal level when the arithmetic device is not operating normally, thereby preventing the communication device from transmitting a signal to the communication network.
