Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/009497
Kind Code:
A1
Abstract:
Provided is an electronic control device that uses a plurality of microprocessors to perform a distributed process, said electronic control device being capable of time synchronization between high-precision microprocessors having low delay, without inhibiting the computation process of each microprocessor. The electronic control device is characterized by comprising: a plurality of microprocessors; and a waveform generation circuit connected between a master microprocessor that is the time synchronization source, and slave microprocessors that perform the time synchronization, among the plurality of microprocessors, the master microprocessor outputting to the waveform generation circuit a reset signal that is time-synchronized, the waveform generation circuit outputting to the slave microprocessors a waveform signal corresponding to the time change of the master microprocessor, and each slave microprocessor measuring the voltage value of the waveform signal and detecting the time corresponding to the measured voltage value.
