Title:
AIR FLOW RATE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/146495
Kind Code:
A1
Abstract:
A processing unit (80) processes a signal outputted from a sensor unit (70) capable of outputting a signal that corresponds to an air intake quantity that is the amount of intake air flowing into an intake flow channel of an internal combustion engine. The processing unit (80) has an advancing process unit (810) and an annealing process unit (830). The advancing process unit (810) performs an advancing process for compensating for a response delay in relation to the signal outputted from the sensor unit (70). The annealing process unit (830) performs an annealing process for annealing a signal that has been processed by the advancing process unit (810).
