Document Type and Number:
WIPO Patent Application WO/2020/195248
Kind Code:
A1
Abstract:
An engine control device (50) controls an engine provided with an EGR device. The engine control device (50) is provided with an abnormality determining unit (55), a restricted operation unit (56), and a restriction released operation unit (57). The abnormality determining unit (55) determines whether an abnormality has arisen in the EGR device. The restricted operation unit (56) performs restricted operation in which some functions of the engine are restricted, if the abnormality determining unit (55) has determined that an abnormality has arisen in the EGR device. If a manipulation to release the restricted operation has been performed, the restriction released operation unit (57) switches from restricted operation to restriction released operation in which the restrictions on some of the functions of the engine are released, and performs said restriction released operation.
