Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/082823
Kind Code:
A1
Abstract:
In the present invention, an ECU (40) stores and retains, in a storage unit (44), NOx information relating to: NOx in exhaust flowing through an exhaust system of a vehicle-mounted engine (10, 200) in a vehicle; or to NOx purification by a catalyst (116, 223) provided in the exhaust system. The ECU is provided with: a parameter acquisition unit (41) that acquires an NOx parameter that is a quantity of effluent NOx flowing out on the downstream side of the catalyst while the engine is running or a correlation value correlating with this quantity of effluent NOx; an integrated value calculation unit (42) that calculates a parameter integrated value by integrating the NOx parameter acquired by the parameter acquisition unit; and a storage processing unit (43) that stores the parameter integrated value in the storage unit as the NOx information.
