Speed Processing Program Design for Electronic Control Engine

Article Preview

Abstract:

Acquiring and processing the speed signal of engine is the foundation to control the engine, whose accuracy determines the quality of control by the electronic control system. This paper takes a gear encoder of 12-1 teeth as an example, through acquiring the crankshaft position signal, calculating the engine speed and TDC, develops a set of generic speed calculation program for electronic control engine, and verifies the feasibility of the program through the test.
