Title:
ECU AND EXHAUST BRAKE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/167394
Kind Code:
A1
Abstract:
Proposed are an electronic control device and an exhaust brake control device with which it is possible to appropriately and promptly determine whether a relay is operating normally. Provided is an ECU (30) that controls an open/close operation of an exhaust flap (19) by transmitting, via a relay (40), a control signal (S1) to the exhaust flap (19). A CPU (31) of the ECU (30) transmits, to the exhaust flap (19), a control signal (S1) that causes operation to the open position, and next transmits a control signal (S1) that causes operation to the closed position. The CPU (31) then determines whether the relay (40) is operating normally on the basis of a first actual opening degree (A1) of the exhaust flap (19) after the control signal (S1) that causes operation to the open position has been transmitted, and a second actual opening degree (A2) of the exhaust flap after the control signal (S1) that causes operation to the closed position has been transmitted.
